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
Who this is for
Any site with air conditioning, and especially estates where no one is sure when each system was last inspected or whose obligation it is.
TM44 is one of the more frequently missed compliance obligations, largely because nothing prompts it. There is no annual return and no reminder, and the requirement sits with the person who controls the system rather than automatically with the building owner.
The regulatory detail, with the threshold, the cycle and what the inspection produces, is set out in the TM44 sheet.
What we examine
- The rated output of every air conditioning system on each site, added together where systems serve the same building, against the 12kW threshold.
- The date of the last inspection and the report lodged for it, so the five-year cycle is established from evidence rather than memory.
- Who controls the operation of each system under the lease, because that decides who the obligation sits with.
- The recommendations in any existing report, read against your consumption data to see which of them are worth acting on.
The process
01
Establish scope
Each site is tested against the threshold and the result is set out in writing: in scope or not, and why.
02
Set the cycle
The last inspection date is evidenced and the next due date recorded against the site, so the obligation surfaces before it lapses.
03
Inspect and lodge
The inspection is carried out and the report lodged on the national register, as the regulations require.
04
Read the recommendations
The report's recommendations are set against your half-hourly or AMR data, so the ones that would change a bill are separated from the ones that would not.
What this does not do
- A TM44 report does not reduce a bill on its own. It identifies where cooling is costing more than it should; the saving comes from acting on the finding.
- The obligation cannot be backdated. If an inspection is already overdue, we say so and get it done; we will not present a late report as anything other than late.
- The recommendations are advisory. Where a report recommends work that the consumption data does not support, we say that too.
The first review costs nothing. Anything after it is quoted and agreed in writing before it starts.
Questions
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.

How to check this
Each claim on this page is answered by something you can read for yourself. Nothing below states a figure; it names the document or register the claim is held against.
Point 01
We hold a Level 1 Letter of Authority only
The authority wording sets out what we may do with your data and states that we cannot sign a contract on your behalf. Read it before you sign it.
Point 02
How we are paid is agreed in writing before you sign
Our margin or management fee is stated in the terms that accompany a recommendation, and nothing is added afterwards.
Point 03
Every figure we quote carries a dated source document
Records state the figure, what it is measured against, the document it is taken from and the date on that document. Records still held anonymous are labelled as such.
Point 04
Compliance work is held against the current legislation
Each obligation is recorded with the rule it comes from and the deadline it carries, in an evidence pack an auditor can follow.
Point 05
We work to a published code of conduct
Our obligations as a third party intermediary, and what you can hold us to, are set out in full.
