Heat load surveys and system design in Leatherhead
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Every Leatherhead quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Leatherhead gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Surrey coverage takes in Leatherhead, about 10 miles from Woking. Coverage includes KT22.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
