Ducted air conditioning in Marlborough
In an older house in Marlborough, the loft and any existing bulkheads decide whether a ducted layout will work. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
For a renovation in Marlborough, the best time to plan ducted cooling is before the plasterers arrive. Our Wiltshire coverage takes in Marlborough, about 10 miles from Swindon. Postcode districts we cover here include SN8.

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
A survey in Marlborough 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. Surveys in Marlborough cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
