Air conditioning for flats and apartments in Hayes
Newer blocks in Hayes with balconies are often the simplest flats to fit. 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.
Balcony-mounted outdoor units are often the neatest solution for flats in Hayes. Our London coverage takes in Hayes, about 13 miles from central London. That includes the UB3 and UB8 postcode districts.
Prices in Hayes
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 Hayes. London is one of the dearer parts of the UK for trades, which shows in the range. 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 Two rooms option (twin multi-split for living room and main bedroom) would typically be £3,495–£5,195 here.
Single room
One wall unit with a balcony outdoor unit.
Two rooms
Twin multi-split for living room and main bedroom.
Whole flat
Three or four rooms on one outdoor unit, concealed routes.
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
For flats in Hayes, the lease and the freeholder's consent come first. Planning rules for blocks of flats are stricter than for houses, and we check them before quoting. 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
On a survey in Hayes 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. A survey in Hayes usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
