The legacy E.ON brand has been closed to new sign-ups since 2022. The only domestic tariff still live on this licence is the Standard Variable Tariff, capped by the Ofgem Energy Price Cap. New customers are routed to E.ON Next; existing legacy-brand customers are being migrated to E.ON Next on a rolling basis. Migration is free, there is no exit fee, and customers can switch externally during the migration window at no cost. Rates below are the Q2 2026 cap level for a typical UK single-rate meter on direct debit, exc. VAT - your real rate depends on your region.

Standard Variable Tariff (legacy)
variable · legacy bookNo fixed term
The only domestic tariff still active on the legacy E.ON licence. Capped quarterly by the Ofgem Energy Price Cap. No exit fee, switch any time. There are no fixed deals on this brand any more - for a fixed-rate offer you need to move to E.ON Next or to a third-party supplier.
Prices verified against the E.ON published price list on May 2026. Always check the live price on the supplier's own website before signing up.
Selectra expert
Which E.ON tariff fits you, and what will you actually pay?
The legacy E.ON brand is in run-off. If you're still on a legacy E.ON account in May 2026 you have three live options: stay on the Standard Variable Tariff, accept the migration to E.ON Next, or switch externally to a fixed deal at a challenger. The cards below explain what each route costs and who each one fits. Figures assume a typical 2,700 kWh electricity + 11,500 kWh gas dual-fuel household at Ofgem Q2 2026 cap levels.
Standard Variable Tariff (legacy)
variable · legacy book
Best fit if — You've been with E.ON since the Powergen days, you have a complex meter setup (Economy 10, dynamic teleswitched, unusual two-rate import/export) that the legacy back office handles cleanly, and you genuinely value the continuity of paper bills, phone-first service and the same agents in Coventry / Nottingham.
Skip if — You want a fixed deal (none are offered on this brand), you rely on a modern app with half-hourly data and live chat, or you actively want to capture savings against the cap. The legacy app receives minimal investment and your unit rate moves with the cap each quarter.
What you'll actually pay
Right on the Ofgem cap - about £1,641 a year on a typical dual-fuel household at Q2 2026 rates (24.70p/kWh electricity, 5.70p/kWh gas, plus standing charges). No exit fee, leave any time. The cap is reviewed each quarter, so your bill can rise or fall on 1 January, 1 April, 1 July and 1 October.
A holding tariff for legacy-meter and continuity-sensitive customers - not a financially competitive choice in 2026.
Migrate to E.ON Next
same group · Kraken platform
Best fit if — You want to stay within the E.ON group but unlock a modern app (Kraken-based, half-hourly data, live chat, in-app DD changes) and the option to take a fixed deal. Migration preserves your account history and is free of charge.
Skip if — You're actively comparison-shopping for the cheapest fixed deal on the UK market - Octopus and EDF Simply Fixed usually undercut E.ON Next's equivalent fixed product by £20-£60 a year on a typical household.
What you'll actually pay
Same SVT cap rates if you do nothing after the migration, or a ~£30-£70 saving versus the cap on the equivalent E.ON Next 12-month fixed product. The migration is mechanical: new login, account number unchanged, balances and direct debit carried across. Allow 4-6 weeks for the move to complete.
The default path. Better tech, similar group, optional fixed deals - accept the letter unless you want to leave the group.
Switch to a challenger fixed deal
external switch · 12-month fix
Best fit if — You want the cheapest market price for your real annual kWh and are willing to leave the E.ON group entirely. Octopus, EDF Simply Fixed and Good Energy (for renewable buyers) are the typical alternatives.
Skip if — You're moving house in the next 12 months (the new supplier's £25-£75 per-fuel exit fee bites), you have a non-standard meter setup that needs operational handling few challengers can do, or you genuinely value the legacy E.ON phone service.
What you'll actually pay
On a typical dual-fuel household, the cheapest fixed deal in May 2026 saves ~£60-£120 a year vs the cap - about £1,520-£1,580 a year. Switch is free, takes 14-21 days, no exit fee from legacy E.ON. Always run the Selectra comparator on your real annual kWh before signing - headline rates lie on edge-case meters.
The right call if your priority is the cheapest cash bill and your meter setup is standard. Compare every 12 months at renewal.
All figures assume a typical 2,700 kWh electricity + 11,500 kWh gas dual-fuel household at Ofgem Q2 2026 cap levels. Your actual bill depends on your region, your meter type and your real annual kWh - always run a quote in the Selectra comparator before signing.
How to compare UK tariffs
Three numbers that decide your bill
1
Unit rate (p/kWh) — the cost of the energy you actually use. The Energy Price Cap caps the unit rate on the default (Standard Variable) tariff. Fixed tariffs are usually slightly above or below the cap.
2
Standing charge (p/day) — what you pay per day even if you use zero energy. Covers network costs, smart-meter rollout and policy levies. About 53p/day for electricity and 32p/day for gas on a typical 2026 tariff.
3
Exit fee — what you pay to leave early on a fixed tariff. Typically £25-£75 per fuel. None on Standard Variable. None in the final 49 days of any fixed contract.

Is E.ON the cheapest for your usage?
Headline rates lie. The only way to know is to compare against your real annual kWh. Selectra's comparison uses your postcode + 12-month usage to find the cheapest current deal.
Every UK domestic energy tariff has two components: a standing charge (a flat fee in pence per day, even if you use zero energy), and a unit rate (in pence per kWh you actually consume). Your bill = (standing charge × days) + (unit rate × kWh used) + VAT (5%). Compare both numbers — a tariff with a low unit rate but a high standing charge can cost more than the reverse if you use little energy.
The Energy Price Cap set by Ofgem limits how much suppliers can charge for the default (Standard Variable) tariff. It is reviewed every three months. It does not cap fixed-term tariffs — those can be cheaper or more expensive than the cap depending on wholesale prices.
Most UK fixed-term tariffs include an exit fee (typical range: £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. The default Standard Variable tariff has no exit fee.
Many UK suppliers offer 'green' or '100% renewable' tariffs which match your annual consumption with REGO certificates. This is a paper-trail match, not a guarantee that the electrons reaching your home are renewable — but it does fund continued renewable generation. Tariffs marked '100% renewable' below carry REGO backing.
If wholesale prices are forecast to rise, fixing locks in today's price for the contract length. If they are forecast to fall, the Standard Variable tariff (capped by Ofgem) tracks the wholesale market down. The right choice depends on your appetite for stability vs. potential savings — Selectra's comparison tool factors in both.
