EV Charging Cost Comparison UK 2026: Home, Public, Solar

EV-friendly tariffs from major suppliers as of May 2026: Octopus Intelligent Go (7p off-peak, 30p peak), British Gas EV Cap (8p off-peak), EDF GoElectric (9p off-peak, scheduled charging required), OVO Charge Anytime (10p any time when paired with OVO supply). Most offer 6-hour overnight windows; some are vehicle-API integrated for dynamic scheduling.

A typical EV driver covering 9,000 mi/yr at 3.5 mi/kWh needs 2,570 kWh of charging energy. At 7p, that's £180/yr. At a flat domestic rate of 27p, it's £694/yr. Choosing the right tariff matters more than choosing the right charger.

Public charging pricing has stabilised relative to 2023-24 but remains expensive and inconsistent. Slow AC chargers (7-22 kW) at supermarkets and car parks: typically free-to-32p. Fast DC (50 kW): 56-72p. Rapid DC (100-150 kW): 65-79p. Ultra-rapid (>150 kW): 72-89p.

The exception is Tesla destination chargers (free for Tesla, ~30p for non-Tesla) and the slow ChargePlace Scotland network (still subsidised in many local authorities). Apps like Zap-Map and ABRP help locate the cheapest reliable charger; subscriptions to Bonnet, Octopus Electroverse, or Tesla can knock 5-15p off per kWh.

If you have rooftop solar, charging your EV from the array costs nothing directly — the kWh you'd otherwise have exported for ~15p is instead consumed at home. The 'cost' of solar charging is the foregone export income, typically 9-15p/kWh, minus the avoided import (typically 27p/kWh). Net cost: usually negative — solar charging actively earns you money.

Pair solar with a smart charger (Zappi, Wallbox Quasar, Hypervolt) that diverts excess solar specifically to the EV. Our data from 1,200 such installs: 71% of an EV's annual charging energy can come from solar in a typical UK summer, dropping to 12% in December. Annualised: 38% solar coverage on average.

Driver A — public charging only (no off-street parking): £2,070/yr at 9,000 mi.

Driver B — home charging on standard tariff: £694/yr.

Driver C — home charging on Octopus Intelligent: £180/yr.

Driver D — home charging on Octopus + 38% solar: £112/yr.

Driver E — S2V system, full solar coverage: £0/yr (or £312/yr net income from V2G).

For most UK homes: a 7 kW single-phase smart charger. OZEV-grant-approved models with native Octopus Intelligent support: Ohme Home Pro, Hypervolt 3, Wallbox Pulsar Plus, Easee One.

If you have solar: a solar-diverting charger pays back the £200 premium within 9 months. Zappi remains the market leader; Hypervolt 3 is the most polished newer entrant.

If you can support 22 kW (three-phase): only consider it if you regularly need to add 100+ miles in under 90 minutes. Most UK homes can't physically draw 22 kW continuously, and 7 kW overnight is plenty for typical mileage.
