New build and renovation air conditioning in Derby
The East Midlands gets warm, dry summer spells, and loft conversions and top-floor bedrooms are where the heat builds. For new Derby extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings.
First-fix pipework in Derby extensions goes in while the joists and studs are open. We cover Derby and the rest of Derbyshire, including Chesterfield and Long Eaton. Homes in DE1 are all within our coverage.
Prices in Derby
In the East Midlands, our guide range for air conditioning for new builds and renovations is £380–£845 per indoor position (first fix), including VAT. That sits a little below the UK middle, reflecting typical East Midlands labour rates. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. For reference, the First and second fix option in Derby (complete install priced per room including units) usually comes to about £1,395–£2,845.

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
On build projects the main thing is timing with your builder and electrician; we fit first-fix pipework before plastering and agree the outdoor unit position early.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. 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.
