Air conditioning for extensions and kitchen-diners in Stowmarket
For a kitchen-diner in Stowmarket, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
An extension in Stowmarket with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Stowmarket sits around 11 miles from Ipswich, inside our Suffolk area. Postcode districts we cover here include IP14.

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.

On a survey in Stowmarket 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.
