What to think about in Gwent
Building Regulations
New or altered ventilation in Wales must meet Approved Document F (Wales). We design to it and hand over the commissioning records.
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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Leased premises
If your Gwent 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.
