Ducted air conditioning in Surbiton
For a renovation in Surbiton, the best time to plan ducted cooling is before the plasterers arrive. 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.
Ducted systems suit Surbiton loft conversions and new extensions where ceilings are being boarded anyway. Our London coverage takes in Surbiton, about 11 miles from central London. We cover KT5 and KT6 and the streets around them.

Planning and permissions
For most houses in Surbiton, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
Surveys in Surbiton cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
