Conservatory air conditioning in Stevenage
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. If your conservatory in Stevenage faces south, that is where overheating is worst.
In Stevenage, the indoor unit usually goes on the original house wall inside the conservatory. Our Hertfordshire coverage takes in Stevenage, about 19 miles from Watford. Homes in SG1 are all within our coverage.

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 Stevenage, 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
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. A survey in Stevenage 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.
