Bedroom and loft air conditioning in Greenwich
Loft conversions and top-floor bedrooms in Greenwich gain heat through the roof all day and give it back at night. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
For bedrooms in Greenwich, we place the outdoor unit at the back of the house, away from neighbours' windows. We cover Greenwich as part of London, roughly 5 miles from central London. Coverage includes SE10.

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
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 Greenwich 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.
