Multi-split air conditioning in Crowthorne
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 Crowthorne homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit.
Multi-split is a good fit for Crowthorne flats and maisonettes where only a balcony or one rear wall is available. We cover Crowthorne as part of Berkshire, roughly 10 miles from Reading. That includes the RG45 postcode district.
Prices in Crowthorne
Budget around £2,995–£9,445 for 2–4 rooms including VAT for multi-split air conditioning in and around Crowthorne. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) would typically be £4,095–£6,645 here.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
Three rooms with mixed indoor styles and Wi-Fi control throughout.
Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
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 Crowthorne 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. 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.
