Air conditioning for flats and apartments in Welling
Balcony-mounted outdoor units are often the neatest solution for flats in Welling. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
Newer blocks in Welling with balconies are often the simplest flats to fit. Our London coverage takes in Welling, about 10 miles from central London. We cover DA16 and the streets around them.
Prices in Welling
Guide prices around Welling run from £1,795 to £7,845 per flat, one room to the whole flat including VAT. That is above the UK middle, mainly because labour and access cost more in London. 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. On our London figures, the Two rooms option (twin multi-split for living room and main bedroom) is about £3,495–£5,195.
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
Flats need more care: get your freeholder's written consent first, and expect the planning rules for a block of flats in Welling to be stricter than for a house. 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 Welling cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Welling at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
