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