New build and renovation air conditioning in Tonbridge
First-fix pipework in Tonbridge extensions goes in while the joists and studs are open. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
For new Tonbridge extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. We cover Tonbridge as part of Kent, roughly 12 miles from Maidstone. We cover TN9 and the streets around them.

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.
