Many UK businesses only think about TM44 when a landlord, managing agent, buyer, tenant, facilities manager or compliance officer asks for the report.

But there is another risk area that often gets overlooked: business insurance.

If your commercial building has air conditioning systems with a combined effective rated output of more than 12kW, you may need a valid TM44 air conditioning inspection report. This is not just another certificate to file away. A TM44 inspection helps demonstrate that the air conditioning system has been assessed by an accredited assessor and reviewed for efficiency, maintenance, controls, sizing and improvement recommendations.

That can matter when a building’s risk profile is being reviewed.

Could missing TM44 compliance automatically invalidate your business insurance? Not necessarily. Insurance policies vary, and the effect of missing compliance would depend on the policy wording, the type of claim, the risk information declared, and the circumstances involved.

But could missing TM44 compliance create uncomfortable questions during insurance renewals, risk reviews, audits, claims handling or commercial property due diligence? Yes, it can.

That is the point many building owners miss.

Business insurance is built around risk. Insurers, brokers and loss adjusters want to understand whether a building is being properly managed, maintained and kept compliant with relevant legal obligations. If a commercial property has sizeable air conditioning systems but no current TM44 report, no clear maintenance records, no evidence of inspection and no compliance file, that can make the building look less professionally managed.

For businesses that want to reduce avoidable risk, TM44 should sit inside the same compliance folder as fire safety, electrical testing, EPCs, F-Gas records, maintenance documents and insurance renewal information.

If you are unsure whether your building needs a report, start by reviewing your TM44 air conditioning inspections position and whether your current evidence is up to date.

What is TM44 compliance?

TM44 is the inspection framework used for air conditioning inspections in qualifying UK commercial and non-domestic buildings.

In simple terms, if your building has air conditioning systems with a combined effective rated output of more than 12kW, it will normally need a TM44 inspection at least every five years. This can include central air conditioning systems, VRF or VRV systems, chillers, cassette units, split systems and multiple smaller units where their combined capacity exceeds the threshold.

A TM44 inspection is not the same as normal air conditioning servicing.

A service visit may check whether the system is working, clean filters, inspect parts, check refrigerant issues and complete maintenance tasks. A TM44 inspection is different. It is an energy assessment of the air conditioning system. It reviews how the system is performing, whether it appears properly maintained, whether controls are suitable, whether the system is appropriately sized, and what improvements may reduce energy use and operating costs.

The outcome is a TM44 report, completed by an accredited assessor. For insurance, audit and compliance purposes, the key issue is not only whether the inspection was done. It is whether the business can produce the right paperwork when asked.

A complete evidence position may include:

The current TM44 report
The TM44 certificate or lodgement evidence
The date of inspection
The expiry or next inspection date
The assessor details
The asset list used during the inspection
Maintenance records
F-Gas records where relevant
Any recommendations and follow-up actions
Internal notes showing who is responsible for compliance

If these documents are missing, scattered or out of date, the business may struggle to prove that the air conditioning system is being properly managed.

Why business insurance providers care about building compliance

Business insurance and commercial property insurance are based on risk assessment.

An insurer may consider many different factors before offering cover, renewing cover or reviewing a claim. These can include the building type, occupancy, use, condition, maintenance standards, fire protection, electrical safety, security, claims history and evidence that the business has managed known risks properly.

Air conditioning may not always be the first thing an insurer asks about. However, in many commercial buildings, air conditioning is an important part of the operational infrastructure.

It affects:

Occupant comfort
Energy use
Plant condition
Maintenance duties
Business continuity
Temperature-sensitive operations
Server room reliability
Tenant satisfaction
Property management standards
Compliance documentation

For some buildings, air conditioning is not just a comfort feature. It may be essential to business operations.

Examples include:

Hotels that rely on cooling for guest comfort
Offices with dense occupancy and meeting rooms
Retail premises with customer-facing trading areas
Gyms and leisure centres with high internal heat loads
Clinics and healthcare premises with treatment rooms
Server rooms requiring controlled temperatures
Restaurants and hospitality venues with high cooling demand
Multi-let commercial buildings with central and tenant systems
Data and IT-dependent businesses where overheating can disrupt operations

If a building depends heavily on air conditioning, poor documentation can create a weak point in the business’s risk profile.

This does not mean every insurer will ask for a TM44 report. But if the building is required to have one, and the report is missing, expired or impossible to locate, it may create avoidable uncertainty.

For commercial properties, TM44 legal requirements for commercial buildings should be treated as part of the wider compliance file, not as a separate technical issue that only the maintenance contractor needs to understand.

Could missing TM44 compliance affect insurance renewal?

Insurance renewal is one of the moments when building compliance becomes more visible.

At renewal, an insurer or broker may ask questions about:

Changes to the building
Changes to business use
Maintenance arrangements
Fire and safety controls
Plant and equipment condition
Previous claims
Risk improvements
Compliance with statutory obligations
Health and safety management
Evidence of inspections and servicing

If the business is asked whether all statutory inspections and compliance requirements are up to date, a missing TM44 report may become relevant.

The problem is often not deliberate non-compliance. It is poor record keeping.

A business may have air conditioning maintenance invoices but no TM44 report. A landlord may assume the tenant arranged it. A tenant may assume the landlord arranged it. A facilities manager may know the system is serviced but may not know whether the total cooling capacity exceeds 12kW. A managing agent may inherit a building with no AC asset register and no inspection history.

During renewal, that creates delay and uncertainty.

An insurer may not specifically say “provide a TM44 certificate.” But if the business is expected to confirm that its building systems are legally compliant, the responsible person should know whether TM44 applies and whether the report is current.

This is why every commercial property should have TM44 inspection evidence stored properly before renewal season, not after a broker or insurer raises a question.

Could missing TM44 compliance affect an insurance claim?

The claim stage is where documentation can become much more important.

When a claim is made, insurers and loss adjusters may review whether the business took reasonable steps to manage the relevant risk. They may ask for maintenance records, inspection documents, service history, compliance certificates and evidence that issues were not ignored.

This does not mean a missing TM44 report will automatically affect every claim. For example, a theft claim may have no direct connection to air conditioning. However, where a claim involves building services, plant condition, overheating, equipment failure, business interruption or maintenance standards, the wider compliance picture may be reviewed.

Potential scenarios include:

A commercial premises suffers disruption because cooling fails during hot weather.
A server room overheats, causing IT disruption or data-related operational loss.
A tenant complains that poor cooling affected business operations.
A hotel experiences guest disruption due to AC failure.
A retail site has repeated cooling issues during peak trading.
A building has plant-related problems and weak service records.
A property manager cannot show whether systems were inspected or reviewed.

In these situations, missing documents can create questions.

The key point is not that TM44 is an insurance product. It is not. The key point is that a TM44 report can form part of the evidence that a commercial air conditioning system has been assessed and that the building owner or responsible person took compliance seriously.

If the business has no report, no asset register, no maintenance history and no clear responsible person, that can look poor during a risk review.

Insurance is also not the only area where this matters. Missing documentation can also become a TM44 commercial property deal risk during sale, lease, refinancing or due diligence.

Business insurance is about evidence, not assumptions

A common mistake is assuming that “we service the AC every year” is enough.

It may not be.

Routine maintenance and TM44 compliance are different things. Both can matter, but they do not replace each other.

A facilities manager may have service sheets from an air conditioning contractor, but those sheets may not show:

Whether the total system exceeds 12kW
Whether a TM44 inspection was required
Whether a TM44 report was completed
Whether it was lodged correctly
Whether the report is still valid
Whether the report reflects the current building setup
Whether recommendations were reviewed
Whether new units were added after the inspection

From an insurance and risk management perspective, assumptions are weak. Evidence is stronger.

A good compliance file should clearly show:

What air conditioning systems are installed
Who controls them
Whether TM44 applies
When the last inspection took place
When the next inspection is due
Who completed the inspection
Where the report is stored
What recommendations were made
What actions were considered or completed

This is why we recommend that commercial building owners create a simple TM44 evidence file. For more detail, use this guide on TM44 compliance file documents businesses should keep.

Example case study: office building with annual AC servicing but no TM44 report

Consider a medium-sized office building in Manchester.

The building has:

Two floors of open-plan offices
Several meeting rooms
A small server room
Reception and common areas
Multiple split AC systems
A few cassette units added during a previous fit-out
Annual air conditioning servicing by a local contractor

The facilities manager believes the building is compliant because the AC contractor attends every year. The business has service invoices and maintenance sheets.

However, no one has calculated the total effective rated output. After reviewing the asset list, the combined capacity is over 12kW. The building should have a TM44 inspection, but no report can be found.

At insurance renewal, the broker asks whether statutory inspections and building compliance documents are up to date. The facilities manager checks the files and realises there is no TM44 evidence.

The business now has a problem. It must either declare that the TM44 position is unclear or urgently arrange a review.

This could have been avoided with a simple compliance tracker.

The lesson is straightforward: annual AC servicing is useful, but it does not automatically prove TM44 compliance.

Example case study: landlord and tenant confusion in a multi-let building

Now consider a multi-let office building in London.

The landlord controls:

Reception cooling
Common area systems
Central plant
Shared risers and roof plant

Several tenants control:

Supplementary split systems
Meeting room cooling
Server room cooling
Small AC units added during fit-outs

The landlord assumes tenants are responsible for their own installed units. The tenants assume the landlord is responsible because the building already has central cooling. The managing agent has maintenance records for common systems, but no complete register of tenant-installed units.

During an insurance review, the landlord is asked for building compliance evidence. The central system has a TM44 report, but it does not include all tenant-installed cooling. Some of the additional systems may affect the total cooling capacity and inspection scope.

This creates uncertainty.

The issue is not just technical. It is contractual and operational. Who controls which system? Who holds the report? Who arranges the inspection? Who pays? Who updates the file when new units are added?

Where responsibility is unclear, use the TM44 responsibility guide to understand the practical issues before they become a dispute.

Example case study: retail business with multiple branches

A retail operator has 18 branches across the UK.

Each branch has air conditioning, but the systems vary:

Some have small split units
Some have larger cassette systems
Some are in shopping centres
Some are high street stores
Some are landlord-controlled
Some are tenant-controlled
Some have old reports
Some have no clear evidence

The business holds a group insurance policy. During renewal, the broker asks for confirmation that site compliance documents are up to date.

The head office team discovers that each branch stores documents differently. Some reports are in local email inboxes. Some branches only have maintenance invoices. Some have expired reports. Some have no asset list at all.

This creates unnecessary pressure.

For multi-site businesses, TM44 should not be handled branch by branch with no central control. It should be managed as a portfolio compliance item.

A proper tracker should include:

Site name
Address
Postcode
AC system type
Estimated capacity
TM44 required: yes/no/unknown
Last inspection date
Expiry date
Report location
Assessor details
Next action
Risk level

For businesses with multiple sites, TM44 portfolio management can help keep reports, inspection dates and renewal evidence under control.

You can also read more about TM44 for multi-site businesses UK if your company operates several commercial premises.

What documents should building owners keep for insurance and compliance?

A well-managed commercial building should have a clear TM44 and AC compliance file.

This does not need to be complicated. The goal is to make sure the right person can find the right evidence quickly.

Your file should include:

Current TM44 report
TM44 certificate or lodgement evidence
Date of inspection
Next inspection due date
Assessor name and accreditation details
AC asset list
Cooling capacity information
Maintenance records
F-Gas records where applicable
Photos or plant references where useful
Recommendations from the report
Notes of actions taken or considered
Responsible person details
Landlord and tenant responsibility notes
Renewal reminder
Broker or insurer correspondence where relevant

This file helps during:

Insurance renewal
Compliance audits
Property sales
Lease negotiations
Tenant enquiries
Managing agent handovers
Facilities management reviews
Enforcement questions
Claims investigations
Internal governance checks

The key is speed. If someone asks for proof, you should not need three weeks to find the report.

If your current report is out of date, read this guide on what happens when a TM44 certificate has expired.

TM44, F-Gas and maintenance records: how they work together

TM44 is often confused with air conditioning servicing and F-Gas compliance.

They are connected, but they are not the same.

AC servicing is routine maintenance. It helps keep systems working efficiently and safely.

F-Gas compliance relates to fluorinated greenhouse gases and leak checking where relevant. It is especially important for systems containing regulated refrigerants.

TM44 is an energy inspection requirement for qualifying air conditioning systems. It reviews system efficiency, controls, maintenance adequacy, sizing and recommendations.

For insurance and risk management, these documents work best together.

A strong evidence file may show:

The system is maintained
The system is inspected where legally required
The system has relevant F-Gas records
The responsible person understands the assets
Recommendations are reviewed
Renewal dates are tracked

A weak evidence file may show only a few invoices and no clear compliance picture.

That difference matters.

The more complete your evidence, the easier it is to respond to questions from insurers, brokers, landlords, tenants, buyers, auditors or enforcement officers.

What if your business cannot find an old TM44 report?

This is common.

Many businesses change office managers, facilities providers, managing agents, landlords, tenants and maintenance contractors over time. Documents get lost. Reports sit in old inboxes. A previous contractor may have closed. A landlord may have changed. A tenant may have left.

If you cannot find your old TM44 report, take these steps:

Check your internal compliance folder
Ask the facilities manager or managing agent
Ask the landlord or tenant, depending on control
Contact your previous AC contractor
Search old email inboxes for “TM44”, “air conditioning inspection” or “ACIR”
Check whether the report was lodged
Review whether the current AC setup has changed
Book a new inspection if the report is missing, expired or unreliable

Do not assume that a missing report exists somewhere.

If the business cannot produce it, the practical compliance position may still be weak.

If you have already received a compliance request or warning, read this guide on TM44 warning letters in the UK and what to do.

How missing TM44 can affect property managers and managing agents

Managing agents carry significant operational responsibility. They often act as the day-to-day controller of building compliance documents, service contractors, tenant communication and landlord reporting.

For managing agents, missing TM44 evidence can create several problems:

Landlords may ask why compliance was not tracked
Tenants may question service charge spending
Insurers may request documentation during renewal
Buyers may raise questions during due diligence
Facilities teams may not know which systems are included
Contractors may only hold maintenance information, not TM44 evidence
Reports may not reflect tenant-installed systems
Renewals may be missed during handover

A managing agent should not rely on memory or informal assumptions. Every qualifying building should have a clear AC compliance record.

This is especially important in buildings with:

Multiple tenants
Common area cooling
Landlord-controlled central systems
Tenant-installed supplementary cooling
Server rooms
Retail units
Clinics or high-use areas
Refurbished floors
Frequent occupier changes

The best protection is a simple, centralised register.

How missing TM44 can affect commercial landlords

For commercial landlords, TM44 is part of the wider property compliance picture.

A missing report may cause issues during:

Insurance renewal
Lease negotiation
Sale due diligence
Refinancing
Tenant disputes
Managing agent reviews
Service charge queries
Regulatory checks
Portfolio audits

Landlords should know which systems they control and whether any tenant-installed systems create additional compliance questions.

For example, a landlord may provide central cooling to common areas and base-build systems. Tenants may install extra AC for meeting rooms, retail spaces or IT rooms. If nobody tracks the combined system position, the building’s compliance file may become incomplete.

The landlord should also consider whether TM44 inspection costs are covered by the lease or service charge provisions. That is not something to assume. The lease should be checked and, where needed, legal advice should be taken.

From a risk perspective, the best approach is to treat TM44 as a routine five-year compliance item, not an emergency document search.

How missing TM44 can affect tenants

Tenants may think TM44 is always the landlord’s problem.

That is not always safe.

If a tenant controls the air conditioning system, installed supplementary units, controls operation, arranges maintenance or occupies a self-contained commercial unit, the tenant may need to understand whether TM44 applies.

This is especially relevant for:

Retail units
Restaurants
Clinics
Gyms
Office tenants
Showrooms
Warehouses with office cooling
Server rooms
Tenant fit-outs
Standalone commercial units

If the tenant’s insurance asks about compliance with legal obligations, the tenant should not assume the landlord holds all relevant evidence.

Tenants should ask:

Who controls the AC system?
Is the system over 12kW?
Is there a current TM44 report?
Does the report include tenant-installed systems?
Who keeps the report?
When is renewal due?
Are maintenance records available?
Is the landlord or tenant responsible under the lease?

This can prevent problems later.

Could an insurer ask directly for a TM44 report?

Yes, it is possible, especially where the insurer, broker, risk engineer or loss adjuster is reviewing building services or compliance documentation.

They may not always use the term “TM44”. They may ask for:

Air conditioning inspection reports
Statutory compliance certificates
Building services inspection records
HVAC maintenance evidence
Energy compliance reports
Plant maintenance schedules
Risk improvement documents
Evidence of compliance with legal obligations

If your building requires a TM44 inspection, the report may be part of the answer.

This is why storing the report correctly matters. The person handling insurance renewal may not be the same person managing building maintenance. If documents are not organised, the business may fail to provide evidence even when an inspection was completed.

Red flags that your TM44 insurance evidence is weak

Your evidence may be weak if:

You cannot find a TM44 report
The report is more than five years old
The report address does not match the current premises
The report does not reflect new AC units
You only have AC service sheets
You do not know the total cooling capacity
No one knows who controls the system
The landlord and tenant disagree on responsibility
The assessor details are missing
No lodgement evidence is available
Recommendations were never reviewed
The report is stored in an old employee’s inbox
The building has been refurbished since the inspection
The AC system has been extended since the inspection
There is no central compliance tracker

Some businesses believe they are covered but still have TM44 hidden failures that can cause fines, especially where reports are old, incomplete or no longer match the current building setup.

How to reduce insurance-related TM44 compliance risk

The solution is practical.

You do not need to overcomplicate it. You need a clear process.

Step 1: Confirm whether your building has air conditioning over 12kW.

Step 2: Confirm who controls the system.

Step 3: Find your current TM44 report.

Step 4: Check the inspection date.

Step 5: Check whether the report is still valid.

Step 6: Check whether the building has changed since the report.

Step 7: Store the report with your insurance and compliance documents.

Step 8: Keep AC maintenance records in the same file.

Step 9: Review recommendations and note any actions taken.

Step 10: Add the next inspection date to your compliance calendar.

Step 11: For multi-site businesses, create a portfolio register.

Step 12: If anything is missing, book a new inspection or compliance review.

If you need to understand the wider duty, review the TM44 inspection requirements UK page before making declarations during insurance renewal or commercial property reviews.

Practical insurance renewal checklist for TM44

Before your next insurance renewal, ask these questions:

Does the building have air conditioning?
Is the combined effective rated output over 12kW?
Is there a current TM44 report?
Is the report less than five years old?
Was the report completed by an accredited assessor?
Is the report stored in the compliance file?
Is there lodgement evidence?
Do we have AC maintenance records?
Do we have F-Gas records if relevant?
Have we added or removed AC units since the report?
Do we know who is responsible for the system?
Have recommendations been reviewed?
Is the next inspection date recorded?
Can we produce the report quickly if asked?

If the answer to any of these is “no” or “not sure”, the building’s evidence position should be reviewed.

TM44 and business interruption risk

Business interruption insurance is designed to protect against certain types of disruption, depending on policy wording.

Air conditioning failure can create operational problems, especially in buildings where cooling is important to trading, occupancy, IT systems or customer experience.

Examples include:

A hotel receiving complaints during a heatwave
A gym losing members because cooling is poor
A server room overheating and causing IT downtime
A retail unit becoming uncomfortable for customers
A clinic needing temperature control in treatment rooms
An office becoming difficult to occupy during summer

TM44 does not prevent every cooling problem. It is not a maintenance contract and it is not a repair service.

However, it can identify issues such as poor controls, inefficient operation, maintenance weaknesses, possible faults, unsuitable sizing or opportunities for improvement. A business that reviews and acts on recommendations may be in a stronger risk management position than one that ignores the system until it fails.

That is why TM44 should be viewed as more than compliance. It can support better building management.

TM44 and directors’ risk management

For company directors and senior managers, the question is simple:

Can the business show that building compliance is being actively managed?

For a small company with one commercial unit, that may mean keeping one folder up to date.

For a larger business with multiple sites, it may require a formal register, renewal reminders and central responsibility.

The risk is not only the cost of an inspection. The bigger issue is poor governance.

A director, finance manager or operations manager should be able to ask:

Which sites need TM44?
Which reports are current?
Which reports are expiring soon?
Who is responsible for renewals?
Are documents stored centrally?
Can we prove compliance during insurance renewal?
Do we have evidence if there is a claim?
Are recommendations being considered?

This is especially important for businesses with group insurance policies, property portfolios, multiple branches or investor reporting requirements.

TM44 and commercial property due diligence

Insurance is only one part of the risk picture.

TM44 may also become relevant during commercial property transactions, including:

Sale of a commercial building
Purchase of an investment property
Lease assignment
New lease negotiation
Refinancing
Portfolio acquisition
Property management handover
Landlord due diligence
Tenant fit-out review

A missing TM44 report can create questions about whether the property has been properly managed. It may not stop a transaction, but it can delay enquiries, create uncertainty or lead to requests for further evidence.

This is why TM44.uk recommends keeping inspection evidence in a property-ready format.

Your TM44 file should be ready for:

The insurer
The broker
The buyer
The tenant
The landlord
The managing agent
The solicitor
The surveyor
The facilities manager
The auditor

If the same file can answer all of those parties, your compliance position is much stronger.

What should a good TM44 report help you understand?

A useful TM44 report should not just exist for compliance. It should help the building owner or manager understand the system better.

It should help identify:

What equipment is present
Whether maintenance appears adequate
Whether controls are appropriate
Whether the system is likely to be efficient
Whether there are obvious faults or operational issues
Whether the system may be oversized or poorly controlled
Where energy savings may be possible
What recommendations should be considered
When the next inspection is due

For insurance and risk management, this matters because the report provides documented evidence. It shows that the system has not simply been ignored.

A poor-quality or incomplete report is less useful. That is why choosing a competent assessor matters.

Should you tell your insurer if TM44 is missing?

If your insurer or broker asks about statutory compliance, building inspections or air conditioning documentation, you should answer accurately.

Do not guess. Do not say everything is compliant if you have not checked.

If you discover that TM44 may be missing, expired or unclear, the best approach is usually to:

Review the building records
Check whether the system exceeds 12kW
Confirm who controls the system
Find any previous report
Book an inspection if required
Update your compliance file
Ask your broker for guidance where necessary

This article is not legal or insurance advice. If you are unsure how missing compliance affects your policy, speak to your insurance broker or legal adviser.

From a practical building management perspective, the safest move is to fix the evidence gap quickly.

Final thoughts

Missing TM44 compliance may not automatically invalidate business insurance. That should not be the claim.

The real issue is more practical.

If your building is required to have a TM44 inspection and you cannot produce a current report, it may raise questions during insurance renewals, risk reviews, claims handling, audits or property transactions. It may also suggest that air conditioning compliance is not being properly tracked.

For building owners, landlords, tenants, managing agents and facilities managers, the answer is simple: treat TM44 as part of your insurance-ready compliance file.

Know whether the rule applies. Keep the report. Track the expiry date. Store maintenance evidence. Review recommendations. Make sure the responsible person is clear.

That is how you reduce avoidable risk and show that your building is being managed professionally.

If your building has air conditioning over 12kW, or you are not sure whether TM44 applies, book a TM44 inspection with TM44.uk and get your compliance evidence in order.

FAQs

Does missing TM44 compliance automatically invalidate business insurance?

Not automatically. Insurance policies vary, and the effect of missing TM44 compliance depends on the policy wording, the type of claim and the circumstances involved. However, a missing or expired TM44 report may create questions during insurance renewals, audits, risk reviews or claims where building compliance evidence is requested.

Can an insurer ask for a TM44 report?

Yes, an insurer, broker, risk engineer or loss adjuster may ask for air conditioning inspection evidence, statutory compliance documents or building services records. They may not always use the term TM44, but if the building is required to have a TM44 inspection, the report may form part of the compliance evidence.

Why might TM44 matter during an insurance claim?

TM44 may matter if the claim involves air conditioning, plant condition, overheating, maintenance standards, business interruption or wider building management. The report can help show that the air conditioning system was assessed and that compliance was not ignored.

Is air conditioning servicing the same as a TM44 inspection?

No. Air conditioning servicing and TM44 inspections are different. Servicing focuses on maintenance and system operation. A TM44 inspection is an energy assessment for qualifying air conditioning systems and includes efficiency, controls, maintenance adequacy, sizing and recommendations.

What documents should I keep with my TM44 report?

You should keep the TM44 report, certificate or lodgement evidence, assessor details, inspection date, expiry date, AC asset list, maintenance records, F-Gas records where relevant, recommendations and any notes showing actions taken or reviewed.

Who is responsible for TM44 compliance in a commercial building?

Responsibility usually sits with the person who controls the air conditioning system. This may be the building owner, landlord, tenant, managing agent or occupier, depending on the lease, building setup and who controls the system.

How often does a TM44 inspection need to be renewed?

For most qualifying commercial air conditioning systems, a TM44 inspection is required at intervals not exceeding five years. If the system has changed significantly, the compliance position should be reviewed earlier.

Can TM44 help with risk management?

Yes. A TM44 report can support risk management by documenting system condition, maintenance adequacy, controls, efficiency and recommendations. It can also help building owners create a stronger compliance evidence file for audits, renewals and property reviews.
