Points to plan for in Dartford
Refrigerant leaks
Topping up without finding the leak is a false economy and, for systems above the threshold, a breach of F-gas leak repair duties.
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.
Switch it off
If water is coming through a ceiling or the unit is tripping, switch it off at the isolator until it is checked.
Leased premises
If your Dartford premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
