Things to check in Bangor, Gwynedd
Building Regulations
New or altered ventilation in Wales must meet Approved Document F (Wales). We design to it and hand over the commissioning records.
Leased premises
If your Bangor, Gwynedd 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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
