How we work in Grays
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Grays we confirm access and parking beforehand.
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.
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.
What to think about in Grays
Leak checks
Larger VRF systems usually exceed 5 tonnes CO2 equivalent, so they need at least annual F-gas leak checks — more often at 50 tonnes and above.
Working hours
Most Grays businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
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.
Premises we work in around Grays
- 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.
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).
Common questions from businesses in Grays
How much does a VRF system cost in Grays?
Guide prices in Grays run from about £2,650 to £5,350 per indoor unit (whole system), plus VAT. A typical job (office floor of 10–16 indoor units) costs £26,500–£85,995 plus VAT. We fix the price in writing after a free survey.
Do you also cover South Ockendon, Gravesend and Dartford?
Yes. Alongside Grays, we also cover South Ockendon, Gravesend and Dartford. Each has its own page with local guide prices.
Which postcodes do you cover in Grays?
All of them, including RM17. Give us your postcode when you enquire and we will confirm the visit details.
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.
What is heat recovery VRF?
A version that can cool some zones and heat others at the same time, moving heat around the building instead of dumping it outside.
