Wall-mounted air conditioning in Dorset

Wall-mounted air conditioning across Dorset

In a semi or terrace in Bournemouth, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. Where a home in Bournemouth faces the street, the outdoor unit usually goes at the rear, out of sight. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.

Prices in Dorset

Guide prices around Dorset run from £1,150 to £2,950 per room including VAT. That is close to the UK middle for this kind of work. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. On our South West England figures, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) is about £1,550–£2,150.

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

Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

The survey

A survey in Dorset 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. 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.
