Multi-split air conditioning in Staines
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. Twin and triple systems suit Staines homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit.
Multi-split is a good fit for Staines flats and maisonettes where only a balcony or one rear wall is available. Staines sits around 8 miles from Woking, inside our Surrey area. Postcode districts we cover here include TW18.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
Surveys in Staines cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Staines 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.
