Before you book in Durham

Diversity

Not every room peaks at once; good design accounts for diversity so central plant is not oversized.

Access and parking

Town-centre jobs in Durham 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.

Coordination

Ceiling, lighting, sprinkler and electrical layouts are coordinated early.

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.

Types of premises we cover in Durham

  • Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
  • Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
  • Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.

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.
