TM44 Government Lodgement Process (UK)
TM44 lodgement is the part most businesses miss. A TM44 inspection alone is not the finish line. If your air conditioning system qualifies, you need the TM44 report properly recorded and submitted, so you can prove compliance during audits, landlord and tenant due diligence, or local authority checks.
At TM44.uk, we manage the full end-to-end process: we inspect your systems on-site, produce a clear TM44 report, submit it to the official TM44 register, and provide proof of lodgement you can rely on. This is built for facilities managers, landlords, managing agents, and multi-site operators who need compliance that stands up when someone actually checks.
If you are not sure whether your system qualifies (especially when multiple split systems add up across floors), do not guess. We can confirm it quickly and quote accurately with the right scope from day one.
What you get with TM44.uk
- TM44 inspection completed on-site by a qualified assessor
- TM44 report produced with clear efficiency recommendations
- TM44 register submission completed correctly
- Proof of lodgement provided for audits and compliance checks
- UK-wide service with portfolio support for multi-site buildings
Not Sure If You Are Compliant?
If you are unsure whether your air conditioning qualifies for TM44, you are not alone. The 12kW threshold catches many sites because capacity is often spread across multiple split systems, multiple floors, or different zones. Some buildings assume they are exempt because no one has ever asked before. That is usually when the problem starts.
The fastest way to confirm your position is simple: send your postcode, building type, and either the number of indoor and outdoor units or an asset list. We will tell you whether TM44 applies, what the correct scope should be, and what lodgement will look like for your site.
If you are in a hurry for an audit or compliance deadline, tell us. We can prioritise urgent cases and help you get compliant without the stress.

What Is TM44 Government Lodgement?
TM44 government lodgement is the formal process of submitting a completed TM44 inspection report to the official TM44 register so it becomes a recognised compliance record. This matters because compliance is not just about having a document saved internally. During audits or enforcement checks, organisations often need to prove that the inspection exists, that it covers the correct systems, and that it has been recorded properly.
Here is the key distinction. A TM44 inspection is the on-site assessment of qualifying air conditioning systems and controls, focusing on energy efficiency and performance. Lodgement is what turns that inspection into a compliance trail that can be verified. Without lodgement, it can be difficult to demonstrate compliance during lease negotiations, landlord requests, due diligence, or local authority reviews.
Most non-compliance issues in TM44 are not caused by technical failures. They are caused by admin errors, missing systems, incorrect scope, or incomplete documentation. That is why we treat lodgement as part of the service, not an optional add-on.
Why TM44 Lodgement Is a Legal Requirement in the UK
TM44 lodgement is legally important because UK compliance is evidence-based. Authorities and auditors are not interested in good intentions or “we booked it”. They check whether the required inspection has been completed, recorded properly, and is available as evidence when requested.
If your building qualifies and the lodgement cannot be verified, your site may be treated as non-compliant even if an inspection took place in the past. That is why enforcement actions and penalty notices often relate to missing records, incorrect scope, or poor compliance documentation. It is not always about the equipment. It is about whether you can prove compliance clearly.
Lodgement also protects you commercially. It supports landlord and tenant compliance discussions, reduces friction with managing agents, and prevents delays when a buyer, tenant, or facilities team asks for proof. The goal is simple: if anyone checks, you can produce the right evidence in minutes.
If you want the full legal context and what it means for commercial buildings, read our regulations guide and legal requirements pages.
Who Is Legally Responsible for TM44 Lodgement?
Responsibility for TM44 lodgement usually sits with the party who controls the air conditioning system, not simply the person who occupies the building. This is where most compliance confusion comes from, especially in multi-let buildings, serviced offices, and sites where tenants install their own split systems.
In practice, responsibility often looks like this:
- If the building owner controls a central system, the owner is typically responsible.
- If a tenant controls and maintains their own installed systems, the tenant may be responsible for those systems.
- If a managing agent is appointed, they may manage compliance on behalf of the owner, but accountability still sits with the legally responsible party.
During audits or enforcement checks, the focus is on the responsible party, not the contractor. That is why it is important to confirm scope early and document which systems are included. If you are not sure who is responsible in your setup, send us the building type and system arrangement. We will tell you what usually applies and how to structure it cleanly.
The TM44 Government Lodgement Process Explained Step by Step
A compliant TM44 lodgement follows a structured process. Skipping steps or rushing the scope is the fastest way to end up with a report that cannot stand up in an audit. Here is how we run it at TM44.uk.
- Step 1: Confirm TM44 applies and define scope
We confirm whether your combined cooling output exceeds 12kW and identify the systems that must be included, including split systems across multiple floors or zones. - Step 2: Asset list and system mapping
We review your asset list (or build one with you) to ensure nothing is missed. Missing systems is one of the most common compliance failures. - Step 3: On-site inspection and assessment
We inspect qualifying systems, controls, zoning, access conditions, maintenance evidence, and operational strategy, then document what is required for the TM44 report. - Step 4: Efficiency findings and improvement recommendations
TM44 is not just a tick-box. We identify practical energy-efficiency opportunities, control improvements, and operational changes that reduce waste. - Step 5: TM44 report creation and quality review
We produce the TM44 report, then review it for accuracy, correct site details, and correct system coverage. - Step 6: TM44 register submission and lodgement confirmation
We submit the report correctly and provide proof of lodgement as compliance evidence for audits and inspections.
If you have multiple sites, we can structure it as a portfolio programme so renewals stay organised and nothing expires unnoticed.
What Information Is Submitted to the TM44 Register
Only complete and accurate information should be lodged on the TM44 register. This information becomes the compliance footprint that auditors and enforcement teams rely on when verifying whether an inspection has been completed properly.
A TM44 register submission typically includes:
- Site and building identification details
- Inspection date and scope confirmation
- Summary of the qualifying air conditioning systems assessed
- Evidence that controls and operational strategy were considered
- Efficiency observations and recommended improvements
- Assessor details and report references
Accuracy matters. If site details are wrong, if systems are missed, or if the scope does not reflect the real installation, compliance can be challenged later. That is why we treat asset list review and scope confirmation as part of the process, not an afterthought.
If you want to understand how the register works and why it is checked, read our TM44 register guide.
How Long TM44 Lodgement Takes
TM44 lodgement timelines depend on two things: the size of your site and how organised the system information is. The inspection itself is completed on-site, but the report and lodgement must be processed accurately so your compliance record stands up during checks.
Typical timelines look like this:
- Smaller sites with a clear asset list: inspection completed quickly, with report and lodgement processed soon after.
- Medium sites with multiple zones: inspection may take longer due to access and system mapping, with report preparation following.
- Large sites or multi-building portfolios: additional coordination is required, especially where plant rooms, roof access, or out-of-hours work is needed.
If you have an upcoming audit, lease milestone, or compliance deadline, tell us when requesting a quote. Urgent cases can often be prioritised.
What Proof of TM44 Lodgement Looks Like
Proof of TM44 lodgement is the evidence that your TM44 inspection has been properly recorded and can be verified when requested. This is what facilities teams, managing agents, landlords, and compliance auditors typically ask for, especially during inspections, ESG reporting, lease renewals, or enforcement reviews.
A proper TM44 compliance pack should include:
- Your TM44 report in PDF format
- Confirmation that the report has been lodged and recorded
- Clear site identification and inspection date for audit trails
- Scope clarity, so it is obvious what systems were included
- A simple reference trail your team can forward when asked
Without proof of lodgement, many businesses struggle to demonstrate compliance even if an inspection took place. That is why we include lodgement and evidence as part of the service, so you are not left trying to “prove it” later under pressure.
Common TM44 Lodgement Mistakes That Cause Non-Compliance
Most TM44 non-compliance is not caused by a broken air conditioner. It is caused by missing records, incorrect scope, or admin mistakes that make the compliance trail unverifiable. These are the most common issues we see when businesses come to us for help.
Common TM44 lodgement mistakes include:
- Assuming the inspection alone is enough without lodgement evidence
- Missing split systems across floors or tenant areas
- Incorrect site details or building identification
- Incomplete asset lists, leading to partial scope
- Poor documentation around controls, zoning, or operational strategy
- Delays caused by access restrictions not planned in advance
- Using providers who do not support the process end-to-end
- No clear proof pack provided for audits
Our process is designed to prevent these failures. We scope properly, map systems, document findings clearly, and provide a clean compliance pack that stands up when checked.
TM44 Lodgement for Multi-Site and Portfolio Buildings
Multi-site and portfolio buildings need a different approach. Each qualifying site must be inspected and lodged individually, and the biggest risk is inconsistency. Different report formats, different scopes, and missed renewals create gaps that show up during audits.
TM44.uk supports portfolio clients with a structured approach:
- Centralised scoping across all sites
- Consistent inspection and reporting format
- Scheduling that prevents missed renewals
- One point of contact for facilities teams and managing agents
- Compliance packs organised per site for quick audit responses
If you manage multiple buildings, the smartest move is to treat TM44 as an organised programme, not a one-off job. Send us your site list and we will propose the cleanest, lowest-friction way to get everything inspected and lodged.
TM44 Lodgement vs Having Only a TM44 Report
A TM44 report is the inspection document. Lodgement is the compliance record that makes the inspection verifiable. This difference matters because auditors and enforcement teams do not rely on internal files alone. They want to see that the inspection exists as a proper compliance trail and can be confirmed.
If you only have a TM44 report, you may still face questions like:
- Does this cover all qualifying systems on the site?
- Can you prove it has been properly recorded for compliance?
- Is this current and within the required cycle?
With inspection plus lodgement, the compliance trail is much stronger. It reduces stress during audits, prevents last-minute scrambling when someone asks for proof, and helps landlords, tenants, and managing agents keep documentation clean.
How TM44 Lodgement Is Checked During Audits and Inspections
During audits and compliance checks, the most common question is simple: can you prove your TM44 inspection has been completed correctly and is current. In many cases, the check is focused on the compliance record and not on what you intended to do.
Audits may happen when:
- A landlord or managing agent updates compliance files
- A tenant requests proof during lease renewals
- A buyer performs due diligence
- A facilities team runs internal compliance reviews
- A local authority or enforcement team investigates compliance
What they typically ask for:
- The TM44 report
- Proof of lodgement or confirmation trail
- Inspection date and scope clarity
- Evidence that qualifying systems were included
We provide a clear compliance pack so your team can respond fast and confidently when asked.
