What to think about in Washington
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 Washington are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Washington 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.
