Heat load surveys and system design in Crowborough
No two rooms in Crowborough 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 Crowborough quote starts with a room-by-room survey rather than a guess from floor area. Crowborough lies roughly 21 miles from Brighton, and we cover it as part of East Sussex. Coverage includes TN6.

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
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. 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.
