How much does a VRF system cost in Hertfordshire?
In Hertfordshire, guide prices 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) usually comes to £26,500–£85,995 plus VAT. The fixed price follows a free survey.
VRF (variable refrigerant flow) — called VRV by some manufacturers — is a commercial air conditioning system where one outdoor unit, or a bank of them, serves many indoor units through a shared refrigerant network.
Our coverage in Hertfordshire
We cover all of Hertfordshire, including Watford, Hemel Hempstead, Stevenage, St Albans and Welwyn Garden City. We quote for premises right across Hertfordshire, including rural and edge-of-town sites.
Postcode districts we cover include AL1, AL8, EN7, HP4, SG6, SG13, WD6 and WD99. We plan installations in Hertfordshire so the noisy work — core drilling, ceiling access, lifting plant — happens when it disturbs your business least.

How it works in Hertfordshire
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 Hertfordshire 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.
Points to plan for in Hertfordshire
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.
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.
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
Access and parking
Town-centre jobs in Hertfordshire 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.
Who we work with in Hertfordshire
- 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.
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.
Common questions from businesses in Hertfordshire
How much does a VRF system cost in Hertfordshire?
Guide prices in Hertfordshire 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 Buckinghamshire, Bedfordshire and London?
Yes. Alongside Hertfordshire, we also cover Buckinghamshire, Bedfordshire and London. Each has its own page with local guide prices.
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.
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.
