What to think about in Belfast
Working hours
Most Belfast businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Access and parking
Town-centre jobs in Belfast often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Conservation areas
Historic streets and listed buildings in and around Belfast 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.
Leased premises
If your Belfast 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.
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.
