What to think about in Cirencester
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
Conservation areas
Historic streets and listed buildings in and around Cirencester are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
