Make, model, capacity, refrigerant and maintenance records are gathered for the assessor.
Inspect
The accredited assessor inspects the systems and controls on site.
Act on the report
You receive the report; we can quote for the recommended improvements.
Local points to consider
England and Wales
Under the Energy Performance of Buildings (England and Wales) Regulations 2012, systems over 12 kW need inspecting at least every five years by an accredited assessor, with the report lodged on the national register. Local Trading Standards enforce it, with a £300 penalty for not having a valid report.
Access and parking
Town-centre jobs in Harrow often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Not an F-gas check
A TM44 inspection is about energy efficiency. It does not replace F-gas leak checks or servicing.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Types of premises we cover in Harrow
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
