Local points to consider
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.
Leased premises
If your County Londonderry 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.
Conservation areas
Historic streets and listed buildings in and around County Londonderry are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
Working hours
Most County Londonderry businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
