Octopus vs E.ON Next: switching bonus and tariff comparison
Last updated: 22 September 2026
Comparing Octopus vs E.ON Next? Here are the joining incentives, this autumn’s prices and exit fees, tariff styles (smart vs traditional), and who each supplier tends to suit. The latest Octopus referral details and the current sign-up link are on my main guide: Octopus referral link and £50 credit guide.
Comparing more than two suppliers? Tariffs, exit fees, supplier comparisons and the referral rules are all in my Octopus Energy guides hub.
Joining incentives: what you might get (and what changes)
Octopus Energy is best known for an always-on referral credit for new customers who switch via a referral link. The headline value is commonly £50 credit, but referral terms can change, and credit is usually applied after your account is live and billing has started.
E.ON Next runs its own refer-a-friend scheme through Mention Me. When a referred friend joins, you both get a £50 voucher. So the headline figure matches. The difference is that Octopus pays account credit off your bill, while E.ON Next pays a voucher to spend elsewhere.
Tip: don’t start a switch via a comparison site if you specifically want a referral reward. Referral eligibility usually depends on starting from the referral route.
Tariffs and features: smart pricing vs standard deals
Octopus leans into smart-meter driven tariffs and “price follows the market” options for people who can shift usage (for example, EV charging or off-peak-heavy homes). If you like tinkering and you have a smart meter, Octopus usually has more interesting tariff shapes.
E.ON Next is often more conventional: a broader spread of fixed and variable options, plus add-on services depending on what they’re promoting. If you want something that feels more like a traditional big supplier set-up, E.ON Next can be the more familiar choice.
Octopus vs E.ON Next prices and exit fees this autumn
Ofgem’s price cap for 1 October to 31 December 2026 is £1,723 a year for a typical dual fuel home paying by Direct Debit, up from £1,663, according to Ofgem’s announcement. That is the benchmark every figure below is measured against.
Octopus publishes its fixed prices for all fourteen regions, so I priced them at Ofgem’s typical use of 2,500 kWh of electricity and 9,500 kWh of gas. E.ON Next quotes by postcode, so its rows show what each tariff promises and what it costs to leave.
| Tariff | Term | Against the October cap | Exit fee |
|---|---|---|---|
| Octopus 12M Fixed | 12 months | £75 to £117 a year above the cap, depending on region | £50 per fuel |
| Octopus 18M Fixed | 18 months | From £7 below to £33 above the cap, depending on region | £75 per fuel |
| Octopus Flexible, Tracker and Agile | Rolling | Moves with the market | None |
| E.ON Next Pledge | Tracks the cap | Guaranteed below the cap, £50 a year saving on average use | £25 per fuel if you leave E.ON Next |
| E.ON Next Fixed 12m | 12 months | Quoted by postcode | £50 per fuel |
| E.ON Next Fixed 24m | 24 months | Quoted by postcode | £100 per fuel |
| E.ON Next Smart Saver | Fixed | Cheaper off-peak electricity, needs a smart meter | None |
Octopus prices are from its public tariff data on 22 September 2026, and the full regional breakdown is in my should you fix your energy tariff guide. E.ON Next terms are from its tariffs page. So this autumn, E.ON Next Pledge promises more than either Octopus fix, although its rate still moves every quarter. Exit fees are charged per fuel, so leaving a dual fuel E.ON Next Fixed 24m early costs £200.
Switching process and ease
Both suppliers use the UK switching system, so your supply stays on throughout. Moreover, Ofgem’s rules require the switch within five working days, or the new supplier pays you £40. The timeline can vary (meter reads, account checks, and supplier admin can slow things down), but the core process is similar: sign up, confirm details, and your supply transfers automatically.
Where people notice differences is usually communication, app/account UX, and how quickly issues get resolved, rather than the switch mechanics themselves.
Customer experience: what people actually care about
- Billing clarity: how easy it is to understand your statements and credit balance.
- Support speed: live chat, email turnaround, and whether problems get closed properly.
- Account tools: app quality, meter read flows, and Direct Debit controls.
Octopus tends to win on “modern account experience”. E.ON Next can be fine day-to-day, but feedback can be more mixed depending on the tariff and how often you need support.
Who should choose which?
Pick Octopus if:
- You want the joining perk as credit off your bill rather than a voucher.
- You have a smart meter and can shift usage to suit smarter tariff options.
- You care about a cleaner, more app-led account experience.
Pick E.ON Next if:
- You want a more traditional supplier feel and a wider mix of standard tariffs.
- You are happy choosing based on whatever fixed deal is best at the time.
- You value bundled energy services when they are available.

If you prefer going direct, you can still switch without a referral.
