Local points to consider
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Alton are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
