New build and renovation air conditioning in Streatham
Renovations in Streatham are the easiest jobs to make invisible, because the pipework goes in before the plaster. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
For new Streatham extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Our London coverage takes in Streatham, about 5 miles from central London. We cover SW16 and the streets around them.
Prices in Streatham
Air conditioning for new builds and renovations in Streatham typically comes in at £495–£1,195 per indoor position (first fix) including VAT, based on London rates. That is above the UK middle, mainly because labour and access cost more in London. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the First and second fix option (complete install priced per room including units) would typically be £1,895–£3,895 here.

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.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
