Compare cheaper prepayment meter tariffs (whole-of-market)

Prepayment meter customers can often access competitive tariffs—especially if you have a smart prepayment meter or you’re able to switch to a credit meter. EnergyPlus is a UK comparison service that helps you check what’s available for your home without guesswork.

Good to know

Prepayment prices can be different from direct debit prices. The cheapest option for you depends on your meter type, your region, and your current supplier’s rules (for example, debt or meter mode).

What you’ll need (2 minutes)

  • Your postcode and whether you have gas, electricity, or both
  • Whether you top up with a key/card, app, or smart meter
  • Rough usage (if you know it)—we can still help if you don’t

Can you switch energy supplier on a prepayment meter?

Usually, yes

Most UK households can switch prepay tariffs. Your new supplier will normally keep you on prepay initially (or move you to smart prepay) and provide new top-up instructions.

Debt can affect switching

If you owe your current supplier, you may be blocked from switching above a certain amount, or your debt may be arranged to transfer depending on supplier rules and your circumstances.

Meter type matters

Traditional key/card meters and smart prepay meters can have different tariff availability. If you’re unsure what you have, we can still compare options.

Tip: If you’re on a prepayment meter due to past debt, ask your supplier whether you can move to credit and what checks apply. It can widen your tariff choice—but it won’t be right for everyone.

How to get a cheaper tariff when you’re on prepay

If you pay as you go, there are still practical ways to cut costs. The right route depends on whether you want to stay on prepayment or move to a monthly bill.

1) Switch to a cheaper prepay tariff

Even if you stay on prepayment, pricing and standing charges can vary by supplier and region.

  • Compare unit rates and standing charges (not just estimated monthly cost)
  • Check if dual fuel is cheaper than separate suppliers
  • Confirm whether the tariff is available for your meter type

2) Move from key/card to smart prepay

Smart prepayment can unlock easier top-ups and clearer usage tracking, which helps many households control spend.

  • Top up online, by app, or phone (depending on supplier)
  • Track daily usage to spot spikes and reduce waste
  • Some suppliers can change tariff settings remotely

3) Switch to a credit meter (where eligible)

Credit meters often come with more tariff choice, including direct debit deals—though approval depends on the supplier and your account history.

  • Ask about removing prepayment mode and any security deposit
  • Check whether any debt arrangement needs to stay in place
  • Consider budgeting: monthly bills can be easier for some, harder for others

4) Reduce usage without losing comfort

Switching tariff is powerful, but small changes can lower spend immediately.

  • Heat rooms you use most; reduce drafts; use radiator valves effectively
  • Wash at lower temperatures and air-dry where possible
  • Turn appliances fully off at the wall to cut standby use

Smart prepayment meters: what changes (and what doesn’t)

A smart prepayment meter still lets you pay as you go, but it can change how you top up and how you manage your energy. That can make it easier to stay in control and avoid unexpected outages.

Common advantages

  • More convenient top-ups (often online/app and at PayPoint)
  • Better visibility of daily/weekly usage
  • Fewer manual readings compared with traditional meters
  • Emergency credit still applies (terms vary by supplier)

Things to watch

  • Tariff availability can differ between smart prepay and key/card
  • Switching may involve a short period where you follow supplier setup steps
  • If you have debt on the meter, deductions may continue after switching
  • Not every property can have a smart meter installed immediately

If you’re not sure whether your meter is smart, look for an in-home display (IHD) and whether you can see near real-time usage. If in doubt, start the comparison form and select “Not sure”.

How switching works on a prepayment meter

Switching supplier is typically straightforward, but prepay has a few extra details. Here’s what most households can expect.

  1. Compare available tariffs
    Choose whether you want to stay on prepay or explore switching to credit (if eligible).
  2. Submit your details
    We’ll use your postcode and meter info to match tariffs available in your area.
  3. Confirm your top-up method
    Your new supplier will explain how to top up (key/card, app, PayPoint, or smart prepay instructions).
  4. Keep your supply on
    Switching should not interrupt supply. Make sure you keep enough credit while the switch completes.
Quick comparison: key/card vs smart prepay vs credit
Feature Key/Card Prepay Smart Prepay Credit (Direct Debit)
How you pay Top up with key/card Top up via app/online/PayPoint (varies) Monthly bill (often cheaper tariffs)
Tariff choice Varies by supplier Often broader than key/card Usually broadest choice
Usage insight Limited Better day-to-day visibility Depends on meter (smart gives best)
Risk of running out Higher if you can’t top up quickly Often lower due to remote/online top-ups Lower (billed after use)

Common reasons prepay customers don’t see cheaper deals (and how to fix them)

Comparing the wrong meter type

Prepay tariffs can be restricted by meter mode. If you pick “credit” by mistake, quotes can look cheaper but won’t be available. Use the form and choose your actual meter type.

Standing charge confusion

A low unit rate can be offset by a higher standing charge. Always compare both—especially for low-usage households.

Debt deductions on the meter

If repayments are taken from top-ups, it can feel like your tariff is expensive. Switching may not remove deductions, but a cheaper tariff can still reduce overall cost.

Prepayment meter tariff FAQs

Is prepayment always more expensive than direct debit?

Not always. Prices vary by supplier and region. Direct debit tariffs can be cheaper and offer wider choice, but some households prefer prepay for budgeting. The best approach is to compare what’s available for your meter and address.

Can I change from prepayment to a credit meter?

In many cases, yes—but it depends on your supplier’s policy, any debt on the account, and whether a meter exchange is required. If approved, credit meters may open up more tariffs, including monthly direct debit deals.

Will switching supplier cut me off?

No—switching supplier should not interrupt your gas or electricity supply. Keep enough credit on your meter during the switch so you don’t run out, and follow any setup steps from your new supplier.

What if I don’t know my usage in kWh?

That’s common for prepay customers. You can still start a comparison with your postcode and meter type. If you can, check your top-up history or your in-home display (for smart meters) to estimate typical usage.

Does my region affect prepay prices?

Yes. Unit rates and standing charges can differ by regional distribution area. That’s why postcode-based comparison is important when looking for a cheaper prepayment meter tariff.

Can I stay on prepay but top up online?

Often yes—if you have smart prepayment (or your supplier offers online top-ups linked to your meter). If you’re on a traditional key/card meter, you may need a smart upgrade to unlock online/app top-ups.

If you’re struggling to keep your meter topped up, you may be eligible for additional support through your supplier or local schemes. It’s worth asking about hardship funds, emergency credit, and payment plans.
