Garden room and home office air conditioning in Richmond

Garden room and home office air conditioning in Richmond

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 Richmond, the outdoor unit usually sits on a small stand behind the building.

Garden offices used every day in Richmond need cooling in summer and efficient heat in winter. Richmond is about 8 miles from central London and falls within our London coverage. We cover TW9 and the streets around them.

Prices in Richmond

Garden room and home office air conditioning in Richmond typically comes in at £1,895–£4,145 per system including VAT, based on London rates. That is above the UK middle, mainly because labour and access cost more in London. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. For reference, the Popular option in Richmond (3.5 kW unit with Wi-Fi to warm up before you walk down the garden) usually comes to 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

For most houses in Richmond, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.

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. On a survey in Richmond 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.
