The steps for a project in Feltham
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 Feltham 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.
Points to plan for in Feltham
Out-of-hours use
If staff work late or weekends, zoning lets you run only the areas in use.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Draughts and noise
Units are positioned so air does not blow directly onto desks, with quiet fan speeds selected for meeting rooms.
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.
Types of premises we cover in Feltham
- 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.

Which postcodes do you cover in Feltham?
All of them, including TW13. Give us your postcode when you enquire and we will confirm the visit details.
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.
Does office air conditioning provide fresh air?
No — it heats and cools the air already in the room. Fresh air comes from ventilation, which we can design alongside the cooling.
