TM44 Air Conditioning Inspections in London and Nationwide

TM44 Inspection for Air Conditioning Over 12 kW

We provide TM44 air conditioning inspections in London and across the whole UK, including Northern Ireland. If the air conditioning in your building has a combined rated output of more than 12 kW, the law requires an inspection by an accredited assessor at least every five years. We cover single sites and national portfolios, lodge the report on the government register (England and Wales), and tell you where the system is wasting energy.

Who needs one

• Any building where the air conditioning adds up to more than 12 kW. All the units count together, so several small split systems usually qualify.
• The duty sits with whoever controls the system, usually the owner or the tenant.
• In England and Wales there is a fixed penalty of £300 for not having a valid report.

What the inspection covers

• Maintenance and F-gas records
• A sample of indoor and outdoor units, air handling units, chillers and controls
• Whether the system is the right size for the building
• Time schedules, set points and control settings
• A report with practical steps to cut running costs

Simple and complex systems (Level 3 and Level 4)

We provide TM44 inspections for simple and complex systems (Level 3 and Level 4) across the whole UK, including Northern Ireland. Level 3 covers simple systems such as split and multi-split units. A Level 4 TM44 inspection covers complex systems such as chillers, air handling units and central plant. Send us the asset list and we will tell you which one your building needs.

We inspect split and multi-split systems, VRF, chillers, air handling units and packaged rooftop units.

TM44 inspections for portfolios across the UK

We provide inspections at multiple sites for national occupiers across England, Wales, Scotland and Northern Ireland. We agree dates with each site contact and supply risk assessments and method statements when asked.

Air conditioning inspection reports in Northern Ireland

In Northern Ireland the same inspection is called an air conditioning inspection report, under the Northern Ireland regulations. The 12 kW threshold and the five-year interval are the same as in England and Wales, and a system installed since 30 December 2008 needs its first inspection within five years. We cover Northern Ireland sites on their own or as part of a UK portfolio.

Combine it with a DEC or EPC

If the building also needs a Display Energy Certificate or a commercial EPC, we can cover it in the same visit, which cuts the cost.

What we need from you

• Asset list with make, model and rated output
• Maintenance and F-gas records
• Floor plans
• Site contact name and phone number, and any access rules

TM44 inspection cost and turnaround

Priced per site, by the number and type of systems. Send the asset list for a free quote.

Turnaround: 5 working days once we have everything we need.

When the first inspection is due

A new system needs its first inspection within five years of being put into service, then at least every five years after that. If the last report is more than five years old, it has lapsed and you need a new inspection.

What your TM44 report tells you

The report shows whether the system is the right size, whether the controls and time schedules match how the building is used, and how well it is maintained. Many of the recommendations, such as resetting set points and schedules or cleaning filters and coils, cost little and can be done by your maintenance contractor.

People often call it a TM44 certificate. It is an inspection report, and in England and Wales it is only valid once lodged on the government register.

Our experience

We have carried out more than 300 TM44 inspections, from single offices and shops to multi-site portfolios.

Questions we get asked

How do I know if my system is over 12 kW? Add up the rated cooling outputs on the unit data plates. If you are not sure, send us the asset list or photos of the plates and we will tell you.

How much does a TM44 inspection cost? It depends on the number and type of systems, so we price each site. Send us the asset list for a free quote. Booking a DEC or commercial EPC in the same visit costs less, as we save on travel.

Do you do TM44 inspections in London and Northern Ireland? Yes. We're based in London and work across the whole UK, including Northern Ireland, from single shops and offices to multi-site portfolios.

Is this the same as servicing or an F-gas check? No. TM44 is an energy inspection. It is required on top of routine maintenance and F-gas leak checks.
