New build and renovation air conditioning in Richmond
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. For new Richmond extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings.
First-fix pipework in Richmond extensions goes in while the joists and studs are open. We cover Richmond as part of London, roughly 8 miles from central London. We cover TW9 and the streets around them.
Prices in Richmond
Air conditioning for new builds and renovations in Richmond typically comes in at £495–£1,195 per indoor position (first fix) including VAT, based on London rates. London is one of the dearer parts of the UK for trades, which shows in the range. What moves a quote in Richmond up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the First and second fix option (complete install priced per room including units) would typically be £1,895–£3,895 here.

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%.
Working with your builder
Because the pipework is built into the structure, coordination with your builder matters more than planning here; the outdoor unit follows the same rules as any other installation.
The survey
A survey in Richmond 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. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
