Local points to consider

Noise

Outdoor unit noise is designed in from the start, not fixed afterwards.

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.

Future use

Allow for growth in occupancy or IT load.

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.

Typical premises in Sevenoaks

  • Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
  • Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
  • Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.

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).
