How we work in Orkney, Shetland and the Western Isles
Calculate
Fresh-air needs are calculated per room. For sites in Orkney, Shetland and the Western Isles we confirm access and parking beforehand.

Local points to consider
Summer bypass
A bypass avoids warming incoming air in summer.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Space
Units need space in the ceiling void or a plant area with access for filter changes.
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.
