Garden room and home office air conditioning in Surbiton
We check the armoured supply cable on every Surbiton garden room before quoting. Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell.
For a garden room in Surbiton, the outdoor unit usually sits on a small stand behind the building. Surbiton is about 11 miles from central London and falls within our London coverage. Homes in KT5 and KT6 are all within our coverage.

Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. On our London figures, the Popular option (3.5 kW unit with Wi-Fi to warm up before you walk down the garden) is about £2,345–£3,245.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
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. Surveys in Surbiton cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
