Garden room and home office air conditioning in Darlington

We check the armoured supply cable on every Darlington garden room before quoting. Darlington lies roughly 17 miles from Durham, and we cover it as part of County Durham. We cover DL3 and the streets around 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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
A survey in Darlington 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. We book surveys in Darlington at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
