Multi-split air conditioning in Walthamstow
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. Twin and triple systems suit Walthamstow homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit.
Multi-split is a good fit for Walthamstow flats and maisonettes where only a balcony or one rear wall is available. Walthamstow lies roughly 8 miles from central London, and we cover it as part of London. Homes in E17 are all within our coverage.

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.

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.
