New build and renovation air conditioning in New Malden
First-fix pipework in New Malden extensions goes in while the joists and studs are open. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
Renovations in New Malden are the easiest jobs to make invisible, because the pipework goes in before the plaster. New Malden lies roughly 9 miles from central London, and we cover it as part of London. Postcode districts we cover here include KT3.
Prices in New Malden
Budget around £495–£1,195 per indoor position (first fix) including VAT for air conditioning for new builds and renovations in and around New Malden. That is above the UK middle, mainly because labour and access cost more in London. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. Typical First and second fix work (complete install priced per room including units) lands around £1,895–£3,895 in this area.

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.
