Points to plan for in Devon
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Conservation areas
Historic streets and listed buildings in and around Devon are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Working hours
Most Devon businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Typical premises in Devon
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.

- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
