Wall-mounted air conditioning in Marlborough
In a semi or terrace in Marlborough, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
A single wall-mounted unit is often all a bedroom or sunny living room in Marlborough needs. Marlborough lies roughly 10 miles from Swindon, and we cover it as part of Wiltshire. That includes the SN8 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%.
Planning and permissions
For most houses in Marlborough, 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
On a survey in Marlborough 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. We book surveys in Marlborough at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
