Local points to consider

Operator duty

The legal duty sits with the operator — the person or business with actual control over the equipment.

Leased premises

If your Darwen 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.

Certified engineers

Leak checks must be done by an engineer holding the right F-gas certification.

Historic streets and listed buildings in and around Darwen are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
