Heat load surveys and system design in South Croydon
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. No two rooms in South Croydon gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
Every South Croydon quote starts with a room-by-room survey rather than a guess from floor area. South Croydon is about 10 miles from central London and falls within our London coverage. We cover CR7 and CR9 and the streets around them.

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
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. Surveys in South Croydon cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
