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.
