How a job in Dereham works
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 Dereham 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.
Conservation areas
Historic streets and listed buildings in and around Dereham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Draughts and noise
Units are positioned so air does not blow directly onto desks, with quiet fan speeds selected for meeting rooms.
Leased premises
If your Dereham 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.
Typical premises in Dereham
- 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.

No — it heats and cools the air already in the room. Fresh air comes from ventilation, which we can design alongside the cooling.
What size air conditioning does an office need?
As a rough guide, offices need about 80–125 W of cooling per square metre, more with lots of glazing, dense occupancy or IT. A heat load survey gives the real figure for each zone.
