Wall-mounted air conditioning in Brentwood
Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat. A single wall-mounted unit is often all a bedroom or sunny living room in Brentwood needs.
Where a home in Brentwood faces the street, the outdoor unit usually goes at the rear, out of sight. Brentwood is about 18 miles from Southend-on-Sea and falls within our Essex coverage. Postcode districts we cover here include CM14.
Prices in Brentwood
Guide prices around Brentwood run from £1,295 to £3,295 per room including VAT. That is above the UK middle, mainly because labour and access cost more in the East of England. What moves a quote in Brentwood up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our East of England figures, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) is about £1,745–£2,395.

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 Brentwood, 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. 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.
