Covering Dereham and nearby
In a town like Dereham, a single wall unit for a shop or a cassette for a surgery makes a real difference in summer. Norwich is about 25 km away.
Postcode districts we cover in Dereham include NR19. We also cover Norwich, Thetford and King's Lynn, all within easy reach of Dereham. Buildings across Norfolk range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.
What we do
- Heat load and diversity calculations for every zone

- Refrigerant pipework sizing, branch selectors and refrigerant charge calculation
- Leak detection where the refrigerant concentration limits require it
- Phased installation, pressure testing, commissioning and full F-gas records

From enquiry to handover in Dereham
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids.
System design
Outdoor units, indoor units, branch boxes and pipe sizes are designed together, including the refrigerant charge and any leak detection.
Phased first fix
Pipework and controls cabling go in floor by floor, often out of hours in occupied buildings. In Dereham we agree timings around your opening hours.
Pressure test and charge
The network is pressure tested, evacuated and charged with the calculated refrigerant quantity.
Commissioning
Each indoor unit is commissioned and the controls set up, with as-fitted drawings and F-gas records handed over.
Before you book in Dereham
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
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.
Refrigerant in occupied rooms
Because one network carries a large refrigerant charge, small rooms on the system are checked against the safety limits in BS EN 378 and may need leak detection.
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.
Typical premises in Dereham
- 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.
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 Dereham?
All of them, including NR19. Give us your postcode when you enquire and we will confirm the visit details.
How long does a VRF system last?
With regular servicing, commercial VRF equipment commonly runs for 15 years or more. Lifespan depends on use, maintenance and the operating environment.
When is VRF better than separate split systems?
Usually once you need more than about six to eight indoor units, want central control, or are short of space for outdoor units. One outdoor unit can replace many.
