Conservatory air conditioning in Barnet
Conservatories and orangeries in Barnet 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 Barnet, the indoor unit usually goes on the original house wall inside the conservatory. Barnet lies roughly 11 miles from central London, and we cover it as part of London. That includes the EN5 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
A survey in Barnet usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. 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.
