Air conditioning for extensions and kitchen-diners in Stratford
The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights. For a kitchen-diner in Stratford, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Stratford with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Stratford lies roughly 6 miles from central London, and we cover it as part of London. Coverage includes E15.

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
For most houses in Stratford, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
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. On a survey in Stratford the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
