We cover every Chelmsford postcode, including CM1 and CM99. We also work in nearby Billericay, Witham and Maldon. In Chelmsford we work with offices, shops and hospitality premises, from a single room to a whole floor; each job starts with a heat load check rather than a guess from the floor area.
What we do
- Heat load assessment per zone (occupancy, IT, lighting, solar gain)
- Zoned design so meeting rooms can be controlled separately
- Ceiling cassettes, ducted units or wall units to suit the ceiling
- Coordination with your fit-out contractor, ceiling and lighting layout
- Commissioning, handover and F-gas records

How it works in Chelmsford
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. In Chelmsford we agree timings around your opening hours.
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.
What to think about in Chelmsford
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 Chelmsford 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.
Out-of-hours use
If staff work late or weekends, zoning lets you run only the areas in use.
Working hours
Most Chelmsford 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 Chelmsford
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
