Compare prepayment meter energy deals in minutes
Prepayment tariffs can differ by region, meter type (smart prepay, key or card) and whether you pay for electricity only or dual fuel. The simplest way to find a suitable deal is to compare the whole market based on your details.
Use the form to request a comparison. We’ll look for tariffs available to prepay households and highlight any restrictions (for example, supplier policies around switching when you have energy debt).
Tip: If you have a smart meter in prepay mode, you may have more top-up options (app, online, PayPoint/Payzone). Tell us your meter type so we can match you accurately.

How prepay meter energy deals work in the UK
A prepayment meter (PPM) lets you pay for gas and/or electricity before you use it. Instead of a monthly bill, you top up credit—traditionally using a key or card, or via a smart meter in prepay mode. Your unit rate and standing charge depend on the tariff you’re on.
If you’re unsure whether you’re on prepay: look for a top-up key/card, a prepay display showing remaining credit, or messages about emergency credit and friendly credit (smart prepay).

Prepayment meter types (and why it matters for deals)
Suppliers may offer different prepay tariffs depending on your meter. Knowing what you have helps you avoid wasted time and ensures you’re quoted accurately.
| Meter type | How you top up | What to watch for | Switching notes |
|---|---|---|---|
| Smart meter (prepay mode) | Often online/app + PayPoint/Payzone | Check emergency credit, friendly credit, and in-home display info | May allow easier tariff changes; some switches still require checks |
| Key meter | PayPoint/Payzone (in-store), then insert key | Lost/damaged keys; standing charge still accrues daily | May need a new key programmed for the new supplier |
| Card meter | PayPoint/Payzone (in-store), then insert card | Card replacement; ensure meter reads updated credit correctly | Some suppliers prefer smart prepay; a meter exchange may be suggested |
Not sure what you have? Put “Not sure” on the form. If you can, note any brand/model on the meter or in-home display and whether you top up online or with a key/card.
Can you switch prepay energy deals if you owe money?
Sometimes. If there’s debt on your prepayment meter, switching may be limited by supplier rules and industry processes. This is common if debt is being recovered through top-ups.
What typically affects switching
- Debt level on the meter/account
- Debt assignment eligibility (if applicable)
- Whether you’re switching gas, electricity or dual fuel
- Your current meter type and whether a meter exchange is required
What you can do now
- Check your meter screen or receipt for any debt recovery amount
- Ask your supplier for a statement of balance and recovery rate
- If you’re struggling, ask about payment support and hardship options
- Still compare deals—knowing your options helps you plan the best route
Important: If you’re self-disconnecting (running out of credit) or can’t top up, contact your current supplier urgently. They can advise on emergency credit, friendly credit (if available), and support options.
Practical ways to make prepay go further
Comparing tariffs is important, but so is avoiding common prepay pitfalls. These steps can help reduce surprises and keep your home supplied.
Watch standing charges
Standing charges apply daily—even if you use little energy. If you don’t top up for a while, charges can reduce your credit when you next add money.
Keep receipts & track credit
If your meter doesn’t update, receipts help your supplier resolve issues. With smart prepay, check your balance and recent top-ups in the app where available.
Use heat efficiently
Small changes add up: reduce flow temperature if appropriate, use thermostatic radiator valves, draught-proof doors, and run appliances on full loads.
Common mistakes when looking for prepay deals
- Comparing the wrong meter type (smart prepay vs key/card) and getting unsuitable quotes.
- Ignoring regional pricing—rates can vary by distribution area, so postcode matters.
- Not checking debt recovery—debt deductions can make your top-ups seem “smaller”.
- Assuming all suppliers will accept a switch—eligibility can depend on meter setup and account status.
Prepay meter energy deals UK: FAQs
Are prepayment meter tariffs more expensive?
Not always, but they can be. Costs depend on your region, the tariff’s unit rate and standing charge, and whether your meter setup restricts which suppliers can accept a switch. Comparing is the fastest way to see what’s available for your home.
Can I switch from prepay to a credit meter?
In many cases, yes—but it’s subject to supplier checks and your circumstances (for example, payment history, debt, and meter location). Some households move from key/card to smart prepay first. If you want to explore this, mention it when you request a comparison.
Do I need my MPAN/MPRN to compare?
It helps but isn’t essential to start. Your postcode and basic details let us check what’s typically available in your area. If we need more accuracy later, we may ask for meter point details from a bill, receipt, or your supplier.
What if my current supplier installed the meter due to debt?
That’s common. Switching may still be possible, but the debt amount and recovery arrangement can affect eligibility. If you’re unsure, request a comparison and include any details you have about the outstanding balance or deductions taken at top-up.
Will switching affect my supply or top-ups?
A switch should not leave you without energy, but prepay changes can involve new top-up instructions (for example, a new key/card or updated smart settings). We’ll outline what to expect for your meter type and supplier.
