Garden room and home office air conditioning in Crawley
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. Garden offices used every day in Crawley need cooling in summer and efficient heat in winter.
For a garden room in Crawley, the outdoor unit usually sits on a small stand behind the building. As well as Crawley itself, our West Sussex coverage takes in Worthing, Bognor Regis and the towns around them. Homes in RH11 and RH77 are all within our coverage.

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
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. On a survey in Crawley 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.
