What is a TM44 inspection and who needs it?

A TM44 inspection is a legal assessment of your building’s air conditioning system to ensure it runs efficiently and complies with UK regulations. If your property has a combined AC output over 12kW, you need one by law.

What happens if I don’t get a TM44 inspection?

Failing to get a TM44 certificate can result in fines up to £1,000. It also affects your energy efficiency and could complicate property sales, leases, or insurance.

How long does a TM44 inspection take?

Most TM44 assessments take just 1–2 hours on-site, depending on your AC system’s size. You’ll get a fully accredited report within 48–72 hours.

TM44 Register Explained

What Is the TM44 Register?

The TM44 Register is the UK government’s official database of lodged air-conditioning inspections. Every valid TM44 certificate must be uploaded to this register by an accredited assessor to prove compliance with the Energy Performance of Buildings Regulations.

If your property has air-conditioning systems with a combined output of more than 12kW, you are legally required to hold a valid TM44 inspection report every five years. But here’s the catch if your certificate is not visible on the TM44 Register, your building is treated as non-compliant, even if you have a private report in your records.

Compliance, Savings & Peace of Mind

Why Your Business Must Appear on the TM44 Register

Compliance Made Simple With TM44.uk

Every commercial building in the UK with air conditioning systems rated above 12kW must, by law, have a valid TM44 inspection certificate lodged on the official government register. Yet today, more than 80% of buildings are still non-compliant

Failing to appear on the TM44 Register puts your business at immediate risk:

Fines Are Rising: From late 2025, penalties for non-compliance jump from £300 to £800 per building – with repeat fines possible every week until you comply.
Inspections On Demand: Trading Standards can request your TM44 certificate at any time. If you can’t produce it within 7 days, you’ll be fined again.
Deal Breaker for Property Transactions: Landlords, tenants, and insurers increasingly require TM44 proof before completing leases, sales, or renewals.

The TM44 Register isn’t just another piece of paperwork. It’s the government’s official record that your building is compliant, energy-conscious, and legally protected. If you’re not on it, you’re exposed to penalties, reputational risk, and lost opportunities.

But there’s an upside too. A properly lodged TM44 certificate unlocks:

Lower energy bills – inspections often highlight simple fixes that cut costs by up to 30%
Extended equipment lifespan – proactive recommendations prevent breakdowns
Audit-ready compliance – certificates instantly verified on the government register
Sustainability proof – supports MEES and net zero targets

⚡ Many of our clients are surprised at how much money and hassle they save just by acting on the recommendations within their TM44 report.

Why Compliance Matters More Than Ever in 2025

TM44 Register by the Numbers

Adding real data makes the risk clear and shows why the TM44 Register isn’t just red tape:

Over 50% of UK commercial buildings inspected under TM44 show areas for energy efficiency improvements — meaning most businesses are paying more than they need to on energy bills.

Fines for non-compliance can reach £800 per site — and these can apply to each building in a portfolio, not just once.

Certificates last just 5 years — many businesses only realise they’ve lapsed when facing an audit or landlord check.

Energy savings of up to 30% are possible when businesses act on recommendations provided in their TM44 report.

Thousands of TM44 certificates are missing from the register each year due to non-accredited assessors or expired reports — leaving owners unknowingly non-compliant.

At TM44.uk, every certificate we issue is lodged directly with the government TM44 Register, so you’re never left exposed.
