New build and renovation air conditioning across Wiltshire
For new Swindon extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Renovations in Swindon are the easiest jobs to make invisible, because the pipework goes in before the plaster. 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.
Prices in Wiltshire
For Wiltshire, 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. Typical First and second fix work (complete install priced per room including units) lands around £1,450–£2,950 in this area.

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
