TM44 Fines in 2025: Proposed Changes Every UK Business Should Know
September 16, 2025
The 2025 TM44 Wake-Up Call
For years, TM44 inspections were ignored by many UK businesses because the fines were lower than the inspection costs. That landscape is about to change.
The UK government has proposed increasing TM44 penalties to £800 per breach in 2025, a sharp rise from the existing £300 fine plus £200 for failing to provide the report when asked. With compliance rates historically below 20%, this new move signals a clear warning: it’s now cheaper to comply than to risk being fined.
In this post, we’ll explain what TM44 inspections are, the current and proposed fines, how enforcement is tightening, and what every facilities manager, landlord, and business owner must do to stay compliant.

What Is a TM44 Inspection? (Quick Refresher)
A TM44 inspection is a legal requirement under the Energy Performance of Buildings Regulations for all air conditioning systems with an effective rated output over 12kW.
Who needs it? Commercial buildings, offices, retail, hospitality, public sector sites – any property with AC above 12kW.
- How often? Every 5 years.
- Who can do it? Only accredited TM44 assessors, who provide a report and lodge it on the government register.
The inspection assesses:
- System efficiency and sizing.
- Energy-saving opportunities.
- Compliance with F-Gas and maintenance standards.

Current TM44 Penalties (as of September 2025)
- £300 fine for failing to have a valid TM44 inspection report.
- £200 additional fine for failing to provide the report to Trading Standards within 7 days of request.
These fines apply per building, so multi-site businesses face multiplied risks.

Proposed TM44 Fine Increase in 2025
The government’s latest consultation proposes raising the non-compliance penalty to £800. This change reflects the view that the current £300 fine is not a strong enough deterrent, especially for large businesses with high energy usage.
👉 Key points:
- Proposed fine: £800 per breach.
- Additional penalties if reports are not supplied on request.
- Stronger enforcement through the central register of lodged reports.
⚠️ While this increase is not yet law, businesses should prepare now. It’s highly likely to be implemented as part of wider EPB reforms.
Why Compliance Rates Are So Low (and Why That’s Changing)
Historic government analysis suggested TM44 compliance was around 20%. Why so low?
-
Fines (£300) were often cheaper than inspection costs.
-
Low awareness among SMEs and landlords.
-
Enforcement was patchy outside major cities.
But with £800 proposed fines, tighter audits, and the public register of inspections, non-compliance will become much riskier in 2025.

TM44 compliance is more than a legal requirement, it’s a chance to lead by example. Every inspection is a step toward lower energy costs, smarter buildings, and a greener planet. By acting now, your business demonstrates vision, responsibility, and integrity, inspiring trust from employees, confidence from customers, and respect across your industry.
TM44 Fines vs Inspection Costs – The Business Math
Let’s break it down:
- Small site (one AC system): Inspection £250–£450. Fine: £800.
- Medium site: Inspection £500–£800. Fine: £800.
- Large multi-site portfolio: Inspection £900+ per site. Fines: £800 per building, so risks multiply quickly.
✅ Conclusion: Even the highest inspection costs are now cheaper than the risk of fines.

Beyond Fines – The Business Case for TM44
Avoiding penalties is only one benefit. TM44 inspections can:
- Cut energy bills: Implementing assessor recommendations can save 10–30% on AC running costs.
- Support Net Zero goals: Reducing carbon emissions is now part of corporate ESG responsibilities.
- Improve building performance: Extend AC lifespan, avoid breakdowns, and reduce maintenance costs.
- Protect brand reputation: Clients, tenants, and investors increasingly expect compliance.
We also provide Energy Efficiency Upgrade Reports after TM44 inspections to help you go beyond compliance.

Industries Most at Risk of TM44 Fines in 2025
- Offices: Particularly multi-tenant buildings in London, Birmingham, Manchester, Leeds.
- Retail chains: Each store with AC requires its own certificate.
- Hospitality: Hotels, bars, restaurants with heavy AC loads.
- Public sector: Schools, universities, NHS sites – all face higher scrutiny.
If you need an urgent inspection for a lease, sale, or audit, we provide Emergency TM44 – 24/48 Hour Service.
How to Stay Ahead – Practical Steps for Compliance
- Check if your building qualifies – any AC system >12kW.
- Locate your last inspection report – if over 5 years old, it’s invalid.
- Use the government’s central register to confirm your certificate status.
- Book a TM44 inspection with an accredited provider.
- Consider bundling services – TM44, EPC Certificates and F-Gas Compliance Checks can often be done together to save money.
- Act early – don’t wait for enforcement officers or a surprise audit.
Many clients pair their inspection with an Energy Efficiency Upgrade Report
Case Example – Compliance Saves More Than Fines
A London office group with three buildings faced potential fines of £2,400 if non-compliant. Instead, they booked TM44 inspections at £1,200 total. The assessor also recommended efficiency upgrades that cut annual cooling costs by 15% (£4,500 saved per year).
👉 Compliance paid back in less than 3 months.
