Multi-split air conditioning in Egham
Multi-split is a good fit for Egham flats and maisonettes where only a balcony or one rear wall is available. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
Twin and triple systems suit Egham homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. We cover Egham as part of Surrey, roughly 8 miles from Woking. Coverage includes TW20.

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
On a survey in Egham 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. We book surveys in Egham at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
