New build and renovation air conditioning in Northampton
In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment. Renovations in Northampton are the easiest jobs to make invisible, because the pipework goes in before the plaster.
First-fix pipework in Northampton extensions goes in while the joists and studs are open. We cover Northampton and the rest of Northamptonshire, including Corby and Kettering. Homes in NN1 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
First-fix work is about coordination, while the outdoor unit follows the normal planning rules for the property.
