Air conditioning for extensions and kitchen-diners in Thetford
An extension in Thetford with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. 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.
In Thetford, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Thetford as part of Norfolk, roughly 27 miles from Norwich. We cover IP24 and the streets around them.
Prices in Thetford
For Thetford, expect roughly £1,595 to £4,995 per space, VAT included, adjusted for typical East of England rates. Prices here sit above the national middle, reflecting East of England labour rates and parking and access costs. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,295–£3,195 here.

One 3.5–5 kW unit for a medium extension.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.

Surveys in Thetford cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
