New build and renovation air conditioning in Harrow
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. For new Harrow extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings.
Renovations in Harrow are the easiest jobs to make invisible, because the pipework goes in before the plaster. We cover Harrow as part of London, roughly 10 miles from central London. Homes in HA2 are all within our coverage.
Prices in Harrow
Air conditioning for new builds and renovations in Harrow 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. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. 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
First-fix work is about coordination, while the outdoor unit follows the normal planning rules for the property.
