Things to check in Richmond
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Conservation areas
Historic streets and listed buildings in and around Richmond are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
