What to think about in Windsor
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.
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.
Not an F-gas check
A TM44 inspection is about energy efficiency. It does not replace F-gas leak checks or servicing.
Conservation areas
Historic streets and listed buildings in and around Windsor are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Premises we work in around Windsor
- 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).
