Wall-mounted air conditioning in Streatham
In a semi or terrace in Streatham, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
Where a home in Streatham faces the street, the outdoor unit usually goes at the rear, out of sight. We cover Streatham as part of London, roughly 5 miles from central London. That includes the SW16 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%.
Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
Surveys in Streatham cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Streatham 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.
