EV Charger Payback Calculator 2025/26

Three main grants are available: the Electric Vehicle Homecharge Scheme (EVHS) gives £350 towards a home charger for eligible EV owners living in flats or rented accommodation; the Workplace Charging Scheme (WCS) gives £350 per socket (up to 40 sockets) for businesses and charities; and the Public ChargePoint Grant (PCG) supports installation of chargepoints in residential on-street locations and small community car parks. All grants are administered through OZEV (Office for Zero Emission Vehicles) and require an OZEV-approved installer.

A 7kW home charger installed at a private residence typically costs £700–£1,400 fully installed. For a domestic EV owner saving approximately 15p/kWh versus public charging, and charging 30–40 miles per day, payback is typically 3–5 years from electricity savings alone. For a landlord or business operator charging tenants or guests at a margin, payback can be shorter — 2–4 years depending on utilisation and charge rate.

Business electricity costs in the UK vary significantly by contract, meter type and consumption profile. In 2025/26, most SME businesses pay 22–35p/kWh on a fixed contract, with half-hourly metered sites potentially accessing lower off-peak rates. Public rapid charger operators typically buy at 20–28p/kWh and charge users 70–90p/kWh. Destination charger operators at hotels or retail parks often use dynamic pricing or flat session fees. Energy brokers can help larger operators secure better rates.
