System inspection drawing

Select a point on the system to see what it decides.

A building's cooling is treated as one system for the threshold test. Each hotspot below is part of the inspection duty.

Rated output

The rated output of every air conditioning system on each site, added together where systems serve the same building, against the 12kW threshold.

Take control with Omnium

Stop the five-year inspection interval lapsing unnoticed.

The inspection interval, the obligation holder and the national register lodging, all tracked rather than left to chance.

  • Interval tracked

    The next inspection is scheduled against the five-year interval, not discovered late.

  • Obligation holder identified

    Whoever controls the operation of the system, which can be the tenant rather than the owner, is identified correctly.

  • Findings linked to cost

    Recommendations identify where cooling is costing more than it should.

  • Lodged on the register

    The completed report is lodged on the national register as part of the inspection.

Where it goes wrong, and what we do about it

  • How Omnium solves it

    We track the inspection interval for every system above the 12kW threshold, so the next inspection is scheduled rather than discovered late.

  • How Omnium solves it

    We identify whoever controls the operation of the system, which can be the tenant rather than the owner, so the obligation is placed correctly.

  • How Omnium solves it

    Recommendations identify where cooling is costing more than it should, and the saving comes from acting on the ones the data supports.

  • How Omnium solves it

    We lodge the completed report on the national register as part of the inspection, so the compliance step does not get missed.

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

An inspection does not reduce a bill on its own.

It identifies where cooling is costing more than it should. The recommendations are advisory, and where the data does not support them, we say that too.

  • 01

    The rated output of every air conditioning system on each site, added together where systems serve the same building, against the 12kW threshold.

  • 02

    The date of the last inspection and the report lodged for it, so the five-year cycle is established from evidence rather than memory.

  • 03

    Who controls the operation of each system under the lease, because that decides who the obligation sits with.

  • 04

    The recommendations in any existing report, read against your consumption data to see which of them are worth acting on.

  1. Each site is tested against the threshold and the result is set out in writing: in scope or not, and why.

  2. The last inspection date is evidenced and the next due date recorded against the site, so the obligation surfaces before it lapses.

  3. The inspection is carried out and the report lodged on the national register, as the regulations require.

  4. 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.

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.
