Garden room and home office air conditioning in Southall
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. We check the armoured supply cable on every Southall garden room before quoting.
For a garden room in Southall, the outdoor unit usually sits on a small stand behind the building. Southall is about 11 miles from central London and falls within our London coverage. We cover UB1 and the streets around them.

Guide prices around Southall run from £1,895 to £4,145 per system including VAT. That is above the UK middle, mainly because labour and access cost more in London.

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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. 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.
