The steps for a project in Dartford
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. We keep work areas in Dartford screened and tidy at the end of each day.
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.
Local points to consider
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.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
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 Dartford
- 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.
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.
FAQs for Dartford
How much does a VRF system cost in Dartford?
Guide prices in Dartford run from about £2,795 to £5,695 per indoor unit (whole system), plus VAT. A typical job (office floor of 10–16 indoor units) costs £27,995–£91,500 plus VAT. We fix the price in writing after a free survey.
Do you also cover Bexley, Swanley and Welling?
Yes. Alongside Dartford, we also cover Bexley, Swanley and Welling. Each has its own page with local guide prices.
Which postcodes do you cover in Dartford?
All of them, including DA1. Give us your postcode when you enquire and we will confirm the visit details.
What is the difference between VRF and VRV?
None in practice. VRV is one manufacturer's trademark; VRF is the generic name for the same type of system.
Does a VRF system need F-gas leak checks?
Usually yes. Most VRF systems hold enough refrigerant to exceed 5 tonnes CO2 equivalent, which triggers at least annual leak checks and record keeping.
