Things to check in Wiltshire
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
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 Wiltshire
- 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.
