Heat load surveys and system design in Greenford
Every Greenford quote starts with a room-by-room survey rather than a guess from floor area. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
For self-builds and extensions in Greenford, a standalone design pack can go straight to your builder. Greenford lies roughly 10 miles from central London, and we cover it as part of London. That includes the UB6 postcode district.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. On a survey in Greenford the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
