Garden room and home office air conditioning in Gravesend
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. For a garden room in Gravesend, the outdoor unit usually sits on a small stand behind the building.
We check the armoured supply cable on every Gravesend garden room before quoting. Gravesend is about 14 miles from Maidstone and falls within our Kent coverage. That includes the DA12 postcode district.

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 Gravesend, 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
On a survey in Gravesend 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. 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.
