Air conditioning for flats and apartments in Westminster
Balcony-mounted outdoor units are often the neatest solution for flats in Westminster. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
Newer blocks in Westminster with balconies are often the simplest flats to fit. Westminster is part of our London coverage. Homes in SW1A, SW1E, SW1H, SW1P, SW1V and SW1W are all within our coverage.
Prices in Westminster
Budget around £1,795–£7,845 per flat, one room to the whole flat including VAT for air conditioning for flats and apartments in and around Westminster. Prices here sit above the national middle, reflecting London 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. For reference, the Two rooms option in Westminster (twin multi-split for living room and main bedroom) usually comes to about £3,495–£5,195.

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%.
Consent and planning for flats
Leaseholders in Westminster usually need the freeholder's consent for anything fixed outside, and blocks of flats often need planning permission for outdoor units. In England, permitted development allows one outdoor unit of up to 0.6 m³ on a block of flats; anything more needs planning permission.
The survey
Surveys in Westminster 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.
