Garden room and home office air conditioning in Battersea
The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights. We check the armoured supply cable on every Battersea garden room before quoting.
For a garden room in Battersea, the outdoor unit usually sits on a small stand behind the building. Our London coverage takes in Battersea, about 2 miles from central London. Coverage includes SW11.

Guide prices around Battersea 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. What moves a quote in Battersea up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed.

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 survey
A survey in Battersea usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. 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.
