Wall-mounted air conditioning in Corsham
Where a home in Corsham faces the street, the outdoor unit usually goes at the rear, out of sight. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
A single wall-mounted unit is often all a bedroom or sunny living room in Corsham needs. Corsham is about 19 miles from Swindon and falls within our Wiltshire coverage. Coverage includes SN13.

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.

On a survey in Corsham the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
