New Build & Conversion Services
A sharper TM44 inspection service for property owners, facilities managers and occupiers who need clear evidence, practical recommendations and a report process that does not slow the building down.
Designed for busy property teams
TM44 inspections are there to assess air conditioning efficiency, controls, maintenance and system sizing. The service should leave you with a report you can actually understand and a clear view of what needs attention.
Assessment of qualifying comfort cooling systems serving commercial premises, offices, shops, schools, clinics and managed buildings.
Clear inspection reports covering system condition, likely efficiency, control settings, maintenance evidence and improvement recommendations.
Support for landlords, managing agents and organisations with multiple premises or staggered renewal dates.
Practical guidance on when reports are due again, what records to keep and what information helps future inspections.
Scope check
In England and Wales, air conditioning systems with an effective rated output of more than 12kW must be regularly inspected by an accredited energy assessor. The inspection interval must be no more than five years.
Several smaller units can count together where they are under single control in the same building. If the capacity is unclear, the equipment labels, O and M manuals, asset list or maintenance records are usually the first place to check.
Inspection scope
The inspection looks at the parts of the system that affect performance, energy use, records and future management.
We review the installed air conditioning equipment, visible condition, system layout, cooling output and how the building is being served.
Process
Each stage is designed to keep the inspection tidy, evidence-led and easy to manage around your building users.
Share the address, building type, number of units and any available AC records.
We review whether the site is likely to fall within TM44 requirements.
We agree a practical attendance plan for plant areas, occupied spaces and records.
The assessor reviews equipment, controls, maintenance evidence and system operation.
You receive clear findings, recommendations and guidance for your records.
Local coverage
Suitable for offices, retail units, hospitality venues, industrial spaces, education buildings, clinics, care settings and multi-tenant commercial sites.
One building, several sites or a portfolio with mixed renewal dates - the inspection process can be planned around how your property is managed.
Report outputs
The report should support compliance records while also highlighting opportunities to improve energy performance and reduce avoidable operating costs.
Assessment of likely efficiency, system condition and opportunities to improve performance.
Review of control settings, operating patterns and whether cooling is being used sensibly.
Comments on maintenance evidence, visible defects and useful records for future inspections.

The person who controls the operation of the system usually has responsibility. Depending on the lease and management arrangement, this may be the owner, occupier, landlord or facilities manager.
The inspection report provides recommendations. The key benefit is that you have a clear view of the system, its efficiency and practical improvement options.
