Garden room and home office air conditioning in Chichester
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Garden offices used every day in Chichester need cooling in summer and efficient heat in winter.
We check the armoured supply cable on every Chichester garden room before quoting. Our West Sussex coverage takes in Chichester, about 32 miles from Crawley. Coverage includes PO19.

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
We book surveys in Chichester at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
