Wall-mounted air conditioning in Welling
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. Where a home in Welling faces the street, the outdoor unit usually goes at the rear, out of sight.
A single wall-mounted unit is often all a bedroom or sunny living room in Welling needs. We cover Welling as part of London, roughly 10 miles from central London. Postcode districts we cover here include DA16.
Prices in Welling
Our London guide price for wall-mounted air conditioning is £1,495–£3,895 per room, VAT included. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. Typical Popular work (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) lands around £2,045–£2,845 in this area.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
A survey in Welling 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. Surveys in Welling cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
