Multi-split air conditioning in Streatham
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. In a house in Streatham with a usable loft, multi-split pipes can often run through it so the front stays clear.
Twin and triple systems suit Streatham homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Streatham lies roughly 5 miles from central London, and we cover it as part of London. Postcode districts we cover here include SW16.

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%.
Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
