TM44 air conditioning inspections

Check.Lodge.Track the cycle.

In short

Air conditioning systems with an effective rated output above 12kW must be inspected at intervals of no more than five years, and the report must be lodged on the national register. The obligation sits with whoever controls the operation of the system, which can be the tenant rather than the owner, and nothing reminds you when it falls due.

What this does not do. An inspection does not reduce a bill on its own. Its recommendations identify where cooling is costing more than it should, and the saving comes from acting on the ones the data supports.

The first review across your invoices costs nothing. Later work is quoted and agreed in writing before it begins. Cost recovery

Questions

What clients ask before starting

For air conditioning systems with an effective rated output above 12kW, at intervals of no more than five years. The threshold catches more buildings than people expect, because the outputs of separate systems serving one building are added together.

The person who controls the operation of the system. Depending on the lease that may be the tenant rather than the building owner, which is exactly why the obligation is so often missed.

No. There is no annual return and no prompting letter. The five-year cycle simply runs, and it runs whether anyone is watching it or not.

No. The recommendations in a TM44 report are not mandatory. They usually identify running costs worth addressing, and we read them against your consumption data so you can see which ones are worth anything.

Establishing whether your sites are in scope and when each inspection falls due costs nothing as part of the first review. The inspection work itself is quoted and agreed in writing before it starts.

Yes. Each system's threshold, last inspection date and next due date is held against the site in the same record as your contracts and meters, so the obligation surfaces ahead of its deadline rather than after it.
