Hounslow and surrounding areas
Hounslow sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
That includes premises in TW3, TW4 and TW6 and the surrounding districts. We also work in nearby Isleworth, Heston and Richmond. We give you the records in a form an inspector, insurer or landlord can read, and remind you when the next check is due.
What we do
- Check of whether your systems meet the 12 kW threshold for your nation
- Collection of system details, records and drawings
- Inspection arranged with an accredited air conditioning energy assessor
- Report with recommendations, lodged where the rules require
- Quote for any recommended improvements

What to think about in Hounslow
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 Hounslow 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.
Leased premises
If your Hounslow premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Premises we work in around Hounslow
- 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).
