New build and renovation air conditioning in Islington
For new Islington extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
First-fix pipework in Islington extensions goes in while the joists and studs are open. Islington is about 3 miles from central London and falls within our London coverage. We cover EC1P, EC4P, N1, N1C, N1P and N7 and the streets around them.
Prices in Islington
Guide prices around Islington run from £495 to £1,195 per indoor position (first fix) including VAT. 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. On our London figures, the First and second fix option (complete install priced per room including units) is about £1,895–£3,895.

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.
