New build and renovation air conditioning in Barnes
The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights. For new Barnes extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings.
First-fix pipework in Barnes extensions goes in while the joists and studs are open. Barnes is about 6 miles from central London and falls within our London coverage. We cover SW13 and the streets around them.
Prices in Barnes
Our London guide price for air conditioning for new builds and renovations is £495–£1,195 per indoor position (first fix), VAT included. London is one of the dearer parts of the UK for trades, which shows in the range. What moves a quote in Barnes up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical First and second fix work (complete install priced per room including units) lands around £1,895–£3,895 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%.
Working with your builder
On build projects the main thing is timing with your builder and electrician; we fit first-fix pipework before plastering and agree the outdoor unit position early.
