Estimated annual home EV charging cost
Default example: 10,000 miles, 3.5 miles/kWh, 10% grid-energy losses, 80% charged at home, 90% eligible for each cheap rate. About 2,540 kWh/year; all home charging at 26.32p/kWh would cost £668. The table changes when you edit the inputs.

| E.ON Next Drive Smart | 8.095p / 31.682p | £265/year | 10.45p/kWh |

These dated values remain here for reference if you change the calculator. Use the official supplier links above for current terms and a postcode quote. E.ON uses its exact published 8.095p rate, often displayed rounded as 8.1p. OVO is an EV-only add-on; the other listed products have whole-home cheap windows. Partner deals, subscriptions and optional rewards are not modelled.

How this EV tariff calculator works
Annual home grid energy = (annual miles ÷ miles/kWh) ÷ (1 − charging loss) × home-charging share. Annual cost = home grid energy × (cheap rate × eligible share + day rate × remaining share) ÷ 100. Percentages are converted to fractions.
The estimate annualises the rates you enter; it does not forecast future prices or spread a short-term quote over changing tariff periods. Standing charges, the rest of the household bill, public charging, subscriptions, exit fees and rewards are excluded. For a full bill comparison, obtain a supplier quote based on your total home use.
Price, carbon intensity and smart charging
The electricity generation and carbon-intensity map gives grid context, not your retail price or a signal guaranteed to qualify for your tariff. Follow your supplier’s smart-charging rules. DriveQuery’s Tesla smart-charging product is in early access development; this calculator does not connect to or control a car.
For a single session, use the UK charging cost calculator. Read the Tesla home charging guide or find nearby public chargers.
Frequently asked questions
What is the best EV tariff in the UK?
It depends on your eligible charging hours, vehicle or charger compatibility, daytime rate and household use. Compare the dated examples below with your own quote; the lowest EV charging estimate is not necessarily the lowest household bill.
Are these live electricity prices?
No. Supplier examples were checked on 13 October 2026. Prices can change; use the official source links and enter the rates from your postcode quote.
Does the calculator include standing charges?
No. It estimates home EV charging energy only. Standing charges, other household electricity, public charging, subscriptions, exit fees and optional rewards are excluded.
Can I use this comparison in Northern Ireland?
These examples and the Ofgem benchmark cover Great Britain. Northern Ireland has a separate retail energy market; use local supplier quotes instead.
Is cheaper electricity always lower carbon?
No. Your retail tariff determines the price you pay, while the electricity map describes generation and calculated carbon intensity. A low price alone does not prove low emissions.
