Heat load surveys and system design in Sittingbourne
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Every Sittingbourne quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Sittingbourne gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Sittingbourne lies roughly 11 miles from Maidstone, and we cover it as part of Kent. Homes in ME10 are all within our coverage.

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
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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
