Energy
Fan upgrades and better controls can cut energy use significantly on older units.
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.
Filters
Filter grades should match the original design or current guidance for the building.
Leased premises
If your Chiswick premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
