Can I switch from a prepayment meter to a cheaper tariff? (UK, 2026)

Yes — in most cases you can switch supplier on prepay, and often move to a credit meter and Direct Debit for cheaper rates. Here are the rules, the steps and the savings in 2026.

  • Your right to switch — even with some debt on the meter
  • How to move from prepay to a credit meter and Direct Debit
  • Compare cheaper tariffs by postcode — no obligation

Fast answer: yes, you can usually switch

You have the right to switch supplier on a prepayment meter, and in most cases you can also change to a credit meter and pay by Direct Debit — which typically lowers both your unit rates and standing charges. Even with some debt on the meter, you can often still switch under the Debt Assignment Protocol.

Key takeaway: moving from prepay to Direct Debit on a credit meter is one of the simplest ways to cut your bill, because Direct Debit price-cap levels are generally lower. Compare deals for your postcode and check the current debt threshold before you start.

Compare cheaper tariffs for your home

A postcode-based quote shows what is available to you on prepay and on a credit meter, so you can see how much moving to Direct Debit could save.

What we use to compare

  1. Postcode — region and standing charges.
  2. Current payment method — prepay now, and the credit-meter option.
  3. Annual usage — from a bill or an estimate.
  4. Meter type — traditional prepay or smart.

No pressure: a quote does not commit you to switching. Review rates and any terms before deciding.

Steps to switch from prepay to a cheaper deal

1) Check your usage and any debt

Note your annual kWh and any balance owed on the meter. This sets your options and which deals you can move to.

2) Compare credit-meter tariffs

Run a postcode comparison for Direct Debit tariffs to see the saving against your current prepay rates.

3) Ask to change meter/payment

Request a credit meter (or smart-meter mode change) and Direct Debit. If renting, get landlord consent first.

Switching when you owe money

Under the Debt Assignment Protocol, prepayment customers can usually switch supplier even if they owe up to a set amount per fuel, with the debt transferring to the new supplier. Larger debts may need to be cleared or arranged first.

Tip: the debt threshold can change over time, so confirm the current figure with your supplier or Citizens Advice. If you are struggling, ask about repayment plans, the Priority Services Register and available support before switching.

Pitfalls to avoid

Comparing prepay against prepay only

The bigger saving usually comes from moving to a credit meter and Direct Debit — compare that option too.

Assuming debt blocks a switch

Smaller debts can often transfer with you. Don’t stay on expensive rates without checking the protocol.

Forgetting landlord consent

If you rent, you usually need permission to change the meter type, though you can switch supplier on prepay yourself.

Missing available support

If money is tight, ask about repayment plans and the Priority Services Register before committing to a new deal.
