EV Charging Costs in the UK
The running cost of an electric vehicle depends significantly on where and how you charge. Home charging overnight on a smart tariff can cost a fraction of public rapid charging. Understanding the cost landscape helps EV drivers make informed decisions and manage energy bills effectively.
- Home charging is cheapest - overnight on an EV-specific smart tariff can cost 7-15p per kWh vs 50-85p at public rapid chargers.
- BP Pulse is one of the largest public charging networks in the UK. Ofgem requires contactless payment at all 50kW+ chargers since November 2024.
- Ofgem price cap sets quarterly limits on domestic electricity unit rates, directly affecting home charging costs.
- The OZEV home charger grant provides up to 350 GBP for eligible properties including renters and flat owners.
Home Charging: The Cheapest Option
A 7kW home wallbox charges most EVs overnight. Cost depends on tariff: standard unit rate under the Ofgem price cap approximately 24-28p per kWh; EV-specific smart tariff with off-peak overnight rates as low as 7-10p per kWh; Economy 7 overnight rates typically 9-15p per kWh. A 60kWh battery costs approximately 4-6 GBP on a smart overnight tariff versus 14-17 GBP on a standard rate.
Public Charging: BP Pulse and Others
BP Pulse operates one of the largest public charging networks in the UK. Public charging is more expensive due to infrastructure costs. Ofgem required contactless payment at all 50kW+ public charge points from November 2024 - eliminating the need for network subscriptions. Public rapid charging typically costs 50-85p per kWh. Check current tariffs on the operator website before charging.
The OZEV Home Charger Grant
The OZEV EV chargepoint grant provides up to 350 GBP towards home charger installation for eligible properties. As of 2026 the grant primarily targets flats and rental properties - the grant for standalone houses closed in 2022. Check gov.uk/government/collections/government-grants-for-low-emission-vehicles for current eligibility.
Workplace Charging
The Workplace Charging Scheme (WCS) supports businesses installing EV charge points - up to 350 GBP per socket for up to 40 sockets. Where available, workplace charging provides a convenient mid-day top-up option for employees.
Frequently Asked Questions
Is home charging much cheaper than public?
Yes, substantially. On an EV-specific overnight tariff, home charging costs 7-10p per kWh. Public rapid charging costs 50-85p per kWh. For a typical annual mileage the difference amounts to hundreds of pounds per year.
Do I need a BP Pulse subscription to use their chargers?
No. Since Ofgem requirement from November 2024, contactless payment is available at all 50kW+ public charge points. You can pay per session without a subscription, though subscription plans may offer lower per-kWh rates for frequent users.
How does the Ofgem price cap affect home EV charging?
The Ofgem price cap sets maximum unit rates for default domestic electricity tariffs, reviewed quarterly. Home EV charging costs are directly linked to these rates if you are on a standard variable tariff. Smart EV tariffs can offer significantly cheaper overnight rates within the cap structure.
Can I install a home EV charger in a rental property?
You need landlord permission. The OZEV grant is available for renters in eligible circumstances. Check gov.uk guidance for current rental property eligibility as rules have changed in recent years.
