Local points to consider
Filters
Filter grades should match the original design or current guidance for the building.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
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.
