Where we work around Carshalton
Premises in Carshalton are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.
That includes premises in SM5 and the surrounding districts. Nearby, we also cover Wallington (about 1 km), Sutton (about 3 km) and Mitcham (about 4 km). Buildings across London range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

Things to check in Carshalton
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
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 Carshalton are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
