New build and renovation air conditioning in Surbiton
First-fix pipework in Surbiton extensions goes in while the joists and studs are open. Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell.
Renovations in Surbiton are the easiest jobs to make invisible, because the pipework goes in before the plaster. Surbiton sits around 11 miles from central London, inside our London area. That includes the KT5 and KT6 postcode districts.

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.
