Garden room and home office air conditioning in Seaham
Cooler North East summers mean cooling is mostly needed in lofts, conservatories and rooms with large windows. For a garden room in Seaham, the outdoor unit usually sits on a small stand behind the building.
We check the armoured supply cable on every Seaham garden room before quoting. Seaham sits around 10 miles from Durham, inside our County Durham area. That includes the SR7 postcode district.

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%.
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.
The survey
We book surveys in Seaham at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in Seaham 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.
