From enquiry to handover in Isleworth
Survey the floor
We look at the ceiling void, the grid layout, window orientation, occupancy and where the outdoor plant can go.
Zone the space
Open-plan, meeting rooms, reception and IT rooms are treated as separate zones with their own controls.
Coordinate the ceiling
Unit positions are set against the lighting and grid layout so cassettes and grilles sit neatly. We keep work areas in Isleworth screened and tidy at the end of each day.
Install around the business
Work is phased by area or done out of hours so staff can keep working.
Commission and train
Controls are set with sensible limits and scheduling, and we show your facilities lead how to manage them.
Before you book in Isleworth
Leases and dilapidations
In a leased office, agree with the landlord who owns the system and what happens at the end of the lease.
Working hours
Most Isleworth businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Out-of-hours use
If staff work late or weekends, zoning lets you run only the areas in use.
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.
Typical premises in Isleworth
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
