How it works in St Helens
Survey the floor
We look at the ceiling void, the grid layout, window orientation, occupancy and where the outdoor plant can go. For sites in St Helens we confirm access and parking beforehand.
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.
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.
Points to plan for in St Helens
Leases and dilapidations
In a leased office, agree with the landlord who owns the system and what happens at the end of the lease.
Leased premises
If your St Helens 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.
Draughts and noise
Units are positioned so air does not blow directly onto desks, with quiet fan speeds selected for meeting rooms.
Working hours
Most St Helens businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Types of premises we cover in St Helens
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
