Conservatory air conditioning across Cornwall
In Truro, the indoor unit usually goes on the original house wall inside the conservatory. If your conservatory in Truro faces south, that is where overheating is worst. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
Prices in Cornwall
Conservatory air conditioning in Cornwall typically comes in at £1,450–£3,450 per system including VAT, based on South West England rates. That is close to the UK middle for this kind of work. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Popular option (5 kW unit with Wi-Fi for a medium conservatory or orangery) would typically be £1,850–£2,595 here.

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.

Planning and permissions
For most houses in Cornwall, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
We book surveys in Cornwall at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Cornwall cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
