From enquiry to handover in County Londonderry
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 County Londonderry 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.
Local points to consider
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.
Draughts and noise
Units are positioned so air does not blow directly onto desks, with quiet fan speeds selected for meeting rooms.
Access and parking
Town-centre jobs in County Londonderry often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Types of premises we cover in County Londonderry
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
Compliance in Northern Ireland: refrigerant work falls under EU F-gas rules that apply in Northern Ireland, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
