Things to check in Durham
Working hours
Most Durham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Conservation areas
Historic streets and listed buildings in and around Durham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Leased premises
If your Durham 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.
Access and parking
Town-centre jobs in Durham 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.
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.
