Conservatory air conditioning in Westminster
If your conservatory in Westminster faces south, that is where overheating is worst. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.

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
We book surveys in Westminster at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Westminster cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
