Local points to consider
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Future use
Allow for growth in occupancy or IT load.
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.
Premises we work in around Chelsea
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
