Conservatory air conditioning in Windsor
Conservatories and orangeries in Windsor can swing from too hot in July to too cold in January. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
In Windsor, the indoor unit usually goes on the original house wall inside the conservatory. Windsor sits around 16 miles from Reading, inside our Berkshire area. Coverage includes SL4.

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.

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