Garden room and home office air conditioning in Daventry
Garden offices used every day in Daventry need cooling in summer and efficient heat in winter. In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment.
We check the armoured supply cable on every Daventry garden room before quoting. Daventry lies roughly 12 miles from Northampton, and we cover it as part of Northamptonshire. We cover NN11 and the streets around them.

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
For most houses in Daventry, 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
On a survey in Daventry 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. We book surveys in Daventry at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
