New build and renovation air conditioning in Windsor
First-fix pipework in Windsor extensions goes in while the joists and studs are open. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For new Windsor extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Windsor lies roughly 16 miles from Reading, and we cover it as part of Berkshire. Coverage includes SL4.
Prices in Windsor
Guide prices around Windsor run from £495 to £1,095 per indoor position (first fix) including VAT. South East England is one of the dearer parts of the UK for trades, which shows in the range. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our South East England figures, the First and second fix option (complete install priced per room including units) is about £1,745–£3,595.

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
Because the pipework is built into the structure, coordination with your builder matters more than planning here; the outdoor unit follows the same rules as any other installation.
