A bypass avoids warming incoming air in summer.
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.
Space
Units need space in the ceiling void or a plant area with access for filter changes.
Conservation areas
Historic streets and listed buildings in and around Carlisle are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
