Before you book in Cornwall
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
Conservation areas
Historic streets and listed buildings in and around Cornwall are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Filters
Filter grades should match the original design or current guidance for the building.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Premises we work in around Cornwall
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
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.
