Multi-split air conditioning in Surbiton
In a house in Surbiton with a usable loft, multi-split pipes can often run through it so the front stays clear. 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.
Multi-split is a good fit for Surbiton flats and maisonettes where only a balcony or one rear wall is available. Our London coverage takes in Surbiton, about 11 miles from central London. Coverage includes KT5 and KT6.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
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. On a survey in Surbiton the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
