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