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.
Working hours
Most Hemel Hempstead businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Not an F-gas check
A TM44 inspection is about energy efficiency. It does not replace F-gas leak checks or servicing.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Who we work with in Hemel Hempstead
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
