Heat load surveys and system design in Chiswick
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. No two rooms in Chiswick gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Chiswick, a standalone design pack can go straight to your builder. We cover Chiswick as part of London, roughly 6 miles from central London. That includes the W4 postcode district.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
On a survey in Chiswick 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. 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.
