Conservatory air conditioning in Harrow
Conservatories and orangeries in Harrow can swing from too hot in July to too cold in January. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
In Harrow, the indoor unit usually goes on the original house wall inside the conservatory. Harrow is about 10 miles from central London and falls within our London coverage. Coverage includes HA2.

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.
