New build and renovation air conditioning in Stevenage
For new Stevenage extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool.
Renovations in Stevenage are the easiest jobs to make invisible, because the pipework goes in before the plaster. We cover Stevenage as part of Hertfordshire, roughly 19 miles from Watford. Postcode districts we cover here include SG1.
Prices in Stevenage
Our East of England guide price for air conditioning for new builds and renovations is £445–£995 per indoor position (first fix), VAT included. That is above the UK middle, mainly because labour and access cost more in the East of England. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. Typical First and second fix work (complete install priced per room including units) lands around £1,595–£3,295 in this area.

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%.
Working with your builder
First-fix work is about coordination, while the outdoor unit follows the normal planning rules for the property.
The survey
On a survey in Stevenage the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. 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.
