Conservatory air conditioning in Dorchester
Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks. In Dorchester, the indoor unit usually goes on the original house wall inside the conservatory.
If your conservatory in Dorchester faces south, that is where overheating is worst. Dorchester sits around 24 miles from Bournemouth, inside our Dorset area. That includes the DT1 postcode district.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
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. 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.
