Heat load surveys and system design in Swanley
No two rooms in Swanley gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Every Swanley quote starts with a room-by-room survey rather than a guess from floor area. Swanley sits around 17 miles from Maidstone, inside our Kent area. We cover BR8 and the streets around them.
Prices in Swanley
For Swanley, expect roughly £495 to £1,495 for a standalone design pack, VAT included, adjusted for typical South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. On our South East England figures, the Design pack option (drawings and schedules for one home) is about £495–£945.

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 Swanley 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.
