New build and renovation air conditioning in Borehamwood
Renovations in Borehamwood are the easiest jobs to make invisible, because the pipework goes in before the plaster. The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool.
For new Borehamwood extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Our Hertfordshire coverage takes in Borehamwood, about 5 miles from Watford. That includes the WD6 postcode district.

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.
