Wall-mounted air conditioning in Borehamwood
In a semi or terrace in Borehamwood, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. 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.
Where a home in Borehamwood faces the street, the outdoor unit usually goes at the rear, out of sight. Our Hertfordshire coverage takes in Borehamwood, about 5 miles from Watford. We cover WD6 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%.
Planning and permissions
For most houses in Borehamwood, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
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. A survey in Borehamwood 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.
