Commercial · Air Conditioning
TM44 air conditioning inspections.
A legal requirement every five years for any building with more than 12kW of combined cooling, which is most offices and a lot of retail. Enforced by local authorities, and very widely ignored.
Who needs one, and how the threshold works.
It is the combined cooling output of every system in the building, not the size of any one unit. Several small splits can take you over it without anyone noticing. Building size is irrelevant.
Most non-domestic premises: offices, retail, hospitality, warehouses, schools and healthcare.
At least once every five years, and sooner if the systems are significantly altered.
Efficiency of the plant, sizing against the actual load, condition and maintenance, controls, and documentation.
Lodged to the national register with recommendations for improving efficiency and reducing energy consumption.
Local authorities enforce it. The practical exposure is usually at sale, letting or audit, when the report is asked for and does not exist.
An accredited TM44 assessor. That accreditation sits with the assessor, so we bring in a specialist and say so rather than implying it is ours.
The report generates recommendations. Controls, zoning and plant replacement are work we can carry out once you decide what is worth doing.
From assessment to lodged report.
We total the cooling capacity across the building to confirm whether you are actually in scope.
An accredited assessor inspects the systems, controls and records.
Report produced and lodged, with recommendations.
The recommendations are advisory. We will tell you which ones pay for themselves and which do not.
Answered
plainly.
Add up the rated cooling output of every air conditioning system in the building. Individual splits are commonly 2.5 to 7kW, so three or four units will often take a building over the threshold. It is the total that counts, not the largest unit.
Local authorities enforce the requirement and can issue penalties. In practice the more common consequence is commercial: the report is requested during a sale, a letting or a compliance audit, and its absence holds up the transaction.
No. An EPC rates the energy performance of the building. A TM44 inspection looks specifically at the air conditioning systems, how efficiently they run and whether they are sized correctly for the space. A building can need both.
Usually the person who controls the systems, which the lease should determine. In a multi-let building with landlord-supplied comfort cooling it is normally the landlord. Where a tenant has installed their own, it is normally the tenant.
The inspection must be done by an accredited TM44 assessor, and that accreditation belongs to the assessor rather than to us. We arrange it, manage it and handle any resulting works, and we will tell you who is carrying it out.
