New build and renovation air conditioning across Kent
Renovations in Maidstone are the easiest jobs to make invisible, because the pipework goes in before the plaster. For new Maidstone extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.

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
A survey in Kent usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. On a survey in Kent the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
