Air conditioning for flats and apartments in Chiswick
The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights. In Chiswick apartment blocks, the freeholder's consent is usually the first thing to sort out.
Newer blocks in Chiswick with balconies are often the simplest flats to fit. Chiswick lies roughly 6 miles from central London, and we cover it as part of London. That includes the W4 postcode district.

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%.
Consent and planning for flats
Leaseholders in Chiswick usually need the freeholder's consent for anything fixed outside, and blocks of flats often need planning permission for outdoor units. In England, permitted development allows one outdoor unit of up to 0.6 m³ on a block of flats; anything more needs planning permission.

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. Surveys in Chiswick cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
