UK farm operations are quietly going electric. Farm pickups, ATVs, agricultural utility vehicles (Gator, Polaris Ranger, Kubota RTV), telehandlers and (increasingly) tractors are available as battery-electric variants. Add visitor traffic to farm shops, glamping pods, equestrian centres and pick-your-own operations, and the case for on-farm EV charging is now compelling on most holdings.
Pair the charger with your existing or planned solar PV array and you remove the marginal cost of electricity entirely. A 7kW workplace charger powered by midday solar generation costs you 4p/kWh (the SEG export you forgo) versus 30p/kWh at retail tariff — a 6.5× saving on every kWh dispensed.
Three farm EV charging use cases
1. Workplace charging (farm staff and fleet)
22kW three-phase or 7kW single-phase chargers installed at staff parking and fleet bays. Typical setup: 4–8 charge points across a working dairy or arable farm. Vehicles charge overnight using stored battery (if you have one) or first-shift midday using direct solar generation. Workplace Charging Scheme grant covers 75% of cost up to £350 per socket (£14,000 cap across 40 sockets).
2. Visitor charging (farm shop, B&B, glamping)
Customer-facing charge points at farm shops, café visitor parking, glamping pods or pick-your-own car parks. Materially increases dwell time — visitors who plug in stay an average 45 minutes longer than those who don't, lifting spend per visit by 30-50%. Charges can be free (loss-leader) or PAYG via Octopus Electroverse, Bonnet or similar app-based payment. UK government On-street Residential Chargepoint Scheme doesn't cover farms, but the EV Infrastructure Grant for SMEs covers up to 75% of cost with £15k cap.
3. Heavy-duty / fleet charging (telehandler, ATV, agricultural)
22kW or 50kW DC fast chargers for telehandlers, electric ATVs and (soon) electric tractors. JCB launched a hybrid telehandler in 2024 with battery-electric capability; John Deere, New Holland and Fendt all have electric prototypes due 2026-2027. Future-proofing fleet charging infrastructure now positions the farm well for the inevitable transition.
Cost ranges for typical farm EV install
| System | Cost | After grant | Notes |
|---|---|---|---|
| Single 7kW workplace | £1,200–£1,800 | £300–£900 | Workplace Charging Scheme 75% up to £350 |
| Single 22kW three-phase | £1,800–£2,600 | £900–£1,700 | Same WCS grant, supply must be three-phase |
| 4-socket workplace cluster | £6,000–£9,500 | £4,600–£8,100 | DNO load assessment usually needed |
| Visitor cluster (4×22kW + 1×50kW DC) | £35,000–£55,000 | £20,000–£40,000 | EV Infrastructure Grant for SMEs, supply upgrade typical |
| Solar load balancing inverter add-on | £1,500–£3,500 | 100% AIA | SolarEdge Smart EV Charger or Zappi integration |
Solar + EV load balancing (the technical bit)
A smart EV charger paired with solar inverter (or battery) operates in three modes:
- Eco mode (solar-only) — charger ramps up/down to match available solar generation. No grid import, no SEG export. Perfect for daytime workplace charging during summer.
- Eco+ mode (solar plus battery) — draws from battery when solar isn't sufficient, never from grid. Best for overnight charging when paired with battery.
- Fast mode (grid-allowed) — full charger output regardless of solar availability. For visitor chargers and emergencies.
The two products that dominate UK farm EV-solar pairing in 2026:
- MyEnergi Zappi — UK-made, three-mode EV-solar charger. 7kW or 22kW variants. Best-in-class app and home automation integration.
- SolarEdge Smart EV Charger — integrates directly with SolarEdge inverter to deliver true solar-tracking charging. Slightly higher capital cost but cleaner installation when paired with new solar.
Workplace Charging Scheme grant (2026 details)
UK Government's Workplace Charging Scheme (WCS) remains the headline EV grant for farms in 2026:
- ✓ Coverage: 75% of total purchase + installation cost
- ✓ Cap per socket: £350
- ✓ Cap per applicant: £14,000 (up to 40 sockets)
- ✓ Eligibility: VAT-registered farm businesses with off-street parking and a dedicated EV charging requirement (staff, fleet, or visitor)
- ✓ Application: via gov.uk OZEV portal, voucher-based — voucher issued first, install completed within 6 months, claim against voucher
- ✓ Stacks with: 100% AIA on the residual cost (i.e. after grant)
EV Infrastructure Grant for SMEs (visitor charging)
For visitor-facing charge points (farm shop, B&B, glamping) the relevant scheme is the EV Infrastructure Grant for SMEs:
- ✓ Coverage: 75% of infrastructure cost including supply upgrade, cable runs, DNO works
- ✓ Cap: £15,000 per grant, one per business
- ✓ Eligibility: SME farm businesses with up to 249 employees
- ✓ Stacks with: Workplace Charging Scheme on the actual chargers
Worked example: 4-charger workplace cluster + solar
A 200-cow dairy with 6 farm staff and 2 contractor pickups installs a 4×7kW workplace cluster (£8,400 gross), runs DNO supply reinforcement (£4,200), and adds load-balancing integration (£2,200). Gross total: £14,800. After Workplace Charging Scheme (£1,400) and EV Infrastructure Grant (£11,100 capped to £15k): net £2,300.
The farm's existing 100kW solar array (already installed) generates 88,000 kWh/year. Adding the EV cluster increases self-consumption from 70% to 78% as vehicles charge during peak generation. Annual additional saving (vs. SEG export forgone): £1,400. Payback on the EV cluster: 1.6 years.
