New build and renovation air conditioning in Barnet
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 Barnet extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings.
First-fix pipework in Barnet extensions goes in while the joists and studs are open. We cover Barnet as part of London, roughly 11 miles from central London. We cover EN5 and the streets around them.

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.

At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. We book surveys in Barnet at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
