Points to plan for in Heston

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.

Conservation areas

Historic streets and listed buildings in and around Heston are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

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.

Types of premises we cover in Heston

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.
