🔌Does Octopus Energy Support Prepayment Meters?
Yes. Octopus Energy fully supports prepayment customers — both smart prepayment meters, which you manage and top up through the Octopus app, and traditional key or card meters, which you top up at PayPoint outlets. If you're currently on prepay with another supplier, you can switch to Octopus and your meter will keep working exactly as before.
Smart prepay is where Octopus really shines. If you have a smart meter (or get one installed for free), it can run in prepayment mode — giving you app-based top-ups, real-time balance tracking, and automatic alerts when credit runs low. No more trudging to the shop in the rain with a key. Learn more about how the meters themselves work in our smart meters guide.
With 7.3 million UK customers, a 4.8/5 Trustpilot rating from 779,000+ reviews, and Which? Recommended status 9 years running, Octopus is also one of the best-rated suppliers for customer support — which matters a lot when you're on prepay and need help quickly.
📲How Topping Up Works
How you top up depends on which type of prepayment meter you have:
Smart prepay customers get the best experience by far — instant top-ups from anywhere, low-balance notifications, and a live view of exactly how much credit is left. If you're on a traditional meter, Octopus will typically offer to upgrade you to a free smart meter, which you can run in prepay or credit mode.
💷Prepayment Pricing — Is Prepay More Expensive?
Prepayment used to carry a hefty premium, but the gap has narrowed significantly. Prepay unit rates are capped by Ofgem under the energy price cap, and since July 2023 prepayment standing charges have been brought broadly in line with direct debit — ending the long-standing “prepay penalty” on daily charges.
That said, prepayment tariffs are typically variable tariffs that track the price cap. What prepay customers usually can't access are Octopus's cheapest smart tariffs — like Agile or the EV tariffs — which generally require a credit meter and direct debit. So while prepay is no longer dramatically more expensive like-for-like, staying on prepay can still mean missing out on the biggest savings. You can compare what's available on our tariffs overview.
🔄Switching From Prepayment to a Credit Meter
If you'd rather pay by monthly direct debit, Octopus can move you from prepayment to a credit meter — and with a smart meter it's usually free and done remotely, with no engineer visit needed. The meter simply switches from prepay mode to credit mode. If you still have a traditional key or card meter, Octopus will typically install a free smart meter first.
A couple of caveats: you may need to pass a credit check, and any outstanding debt on the prepayment meter usually needs to be cleared before the switch. If you rent, it's worth a quick check of your tenancy agreement too — our renters guide covers what landlords can and can't object to.
Why bother? Moving to credit + direct debit unlocks the good stuff:
Credit meter customers can access tariffs like Agile Octopus, with half-hourly pricing that can even go negative.

A monthly direct debit spreads costs evenly across the year — no more watching the balance or emergency dashes to top up.
Set-and-forget billing
Your supply never cuts off because credit ran out. You pay for what you use, accurately, via smart meter readings.

🆘Emergency Credit & Support
Running out of credit doesn't mean instantly losing supply. Octopus smart prepay includes friendly-credit hours — typically overnight, and often on weekends and bank holidays — during which your supply stays on even if your balance hits zero. Anything used during friendly-credit hours is deducted from your next top-up.
On top of that, there's emergency credit — typically around £30 — that you can activate when your balance runs out, giving you a buffer until you can top up. Exact amounts and friendly-credit windows can vary, so check your account or the app for the figures that apply to your meter.
If you're struggling to afford top-ups, Octopus has a strong reputation for support: its financial-support team can set up payment plans, apply for support schemes on your behalf, and in genuine hardship cases has been known to add discretionary credit. Don't self-disconnect in silence — get in touch with them first.
✅Can Prepay Customers Get the £50 Referral Credit?
Yes. The £50 referral credit applies when you switch supplier to Octopus Energy using a referral link — and that includes prepayment customers. Once your switch completes, the credit is added to your account. Switching takes less than 5 minutes and Octopus handles everything with your old supplier — see how switching works.
Verdict: Octopus is one of the best suppliers for prepayment customers.
App-based smart prepay top-ups, friendly-credit hours, around £30 of emergency credit, and award-winning support make Octopus a genuinely good home for prepay households. And when you're ready, the free switch to a credit meter unlocks the cheapest smart tariffs in the UK. Either way, switching supplier to Octopus via a referral link earns you £50 free credit.
