New build and renovation air conditioning in Daventry
Summer peaks in the East Midlands make bedrooms under the roof the hardest rooms to keep comfortable. Renovations in Daventry are the easiest jobs to make invisible, because the pipework goes in before the plaster.
For new Daventry extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Our Northamptonshire coverage takes in Daventry, about 12 miles from Northampton. Homes in NN11 are all within our coverage.

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.
