New build and renovation air conditioning in Devizes
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. For new Devizes extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings.
First-fix pipework in Devizes extensions goes in while the joists and studs are open. Devizes lies roughly 17 miles from Swindon, and we cover it as part of Wiltshire. That includes the SN10 postcode district.
Prices in Devizes
For Devizes, expect roughly £395 to £895 per indoor position (first fix), VAT included, adjusted for typical South West England rates. 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. As an example, the First and second fix option (complete install priced per room including units) would typically be £1,450–£2,950 here.

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%.
Working with your builder
First-fix work is about coordination, while the outdoor unit follows the normal planning rules for the property.
The survey
A survey in Devizes 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.
