Timing depends on the tariff terms. For EDF Power Perks, EDF currently says eligible event credits are usually added during the first week of the month after the event, once the smart-meter readings needed to calculate the credit are complete.

If a promised tariff credit is missing, check the scheme terms and your smart-meter readings first, then ask the supplier to trace the credit.

Check EDF Power Perks credit timing

For EDF Power Perks, credit is usually monthly

EDF's current Power Perks page says participating customers will see the credit monthly on the bill as “Power Perks credit”. For Free Electricity events, EDF says it will usually add the credit during the first week of the month after the event. So an event held in October would normally show a credit in the first week of November.

That wording matters. “Usually” is not the same as a guarantee for every account. EDF says it needs complete smart-meter readings for the event period. Missing, delayed or incomplete readings can prevent or delay the credit being applied.

The supplier has to calculate the credit

These rewards are not normally a fixed cash rebate detached from usage. EDF says it calculates the free-electricity credit using the electricity you used during the event and the unit rate on your eligible tariff at that time. That is why the credit can differ between households even when they take part in the same event.

The easiest way to check a missing credit is therefore to compare three things: the event date, the smart-meter data for that period and the tariff rate used in the calculation. A credit that looks different from what you expected is not necessarily an error.

Why smart-meter data matters

Power Perks requires a compatible smart meter set up to send half-hourly readings. If the meter is not communicating correctly, the supplier may not have the complete data needed to verify the event. Before contacting EDF, check whether your account shows current readings and whether any meter issue has already been reported.

This is a wider lesson with energy rewards: the reward timetable can depend on data arriving before the supplier can calculate it. A promotion saying “credit next month” does not necessarily mean the credit will appear on the first bill issued after the event.

A tariff credit is not always cash in your bank

EDF says Power Perks credits are added directly to the EDF energy account. Its current terms say the credit cannot be exchanged for cash, transferred to another person or moved to another energy account. So a credit appearing on the bill is not the same thing as a bank refund.

That distinction is useful when you are comparing a reward against a cheaper tariff. A £20 account credit reduces the amount you owe EDF, but it does not create £20 of unrestricted cash.

Do not confuse rewards with ordinary account credit

A normal energy account can also be “in credit” because you have paid more by Direct Debit than you have used. Ofgem says you can contact your supplier to claim ordinary account credit back at any time, although you should consider whether keeping some credit is sensible for future bills.

Ofgem's latest market data, published in October 2026, shows that household energy credit balances move seasonally and that the average household balance at the end of June 2026 was £182 for the group covered by its analysis. That is a separate concept from a reward credit.

What to do if a reward credit is missing

  1. Check the event date and the month in which the credit should normally appear.
  2. Check that your smart meter is sending complete readings.
  3. Read the tariff or rewards terms for any eligibility conditions.
  4. Take screenshots or save the event notification if you received one.
  5. Ask the supplier to explain the calculation if the credit is absent or looks wrong.

If the supplier does not resolve the issue, use its complaints process and then the Energy Ombudsman route where available. Citizens Advice can also help with energy complaints and account-credit disputes.

What happens to credit if you switch?

Ordinary account credit should be reflected in the final bill and refunded. Ofgem says your old supplier should refund credit in the final bill when you switch. That is different from a scheme reward that the tariff terms may restrict to the supplier account itself.

Illustrative account credit after a tariff reward
Existing credit£7.60Reward credit£12.40Total credit£20

Worked example

Illustrative example: Priya takes part in an eligible EDF Power Perks event on 18 October 2026. EDF's current guidance says the credit would normally be added during the first week of November, provided the smart-meter readings are complete.

  • Suppose the event produced an illustrative credit of £12.40.
  • Priya's account already has £7.60 of ordinary credit.
  • The combined account credit after the reward appears would be £7.60 + £12.40 = £20.00.
  • That £20 is account credit rather than £20 deposited into Priya's bank account.

Illustrative values are used for the amounts. The actual reward depends on event usage, the tariff rate and whether EDF has complete meter data.

Keep the event confirmation so the supplier can trace the reward if the expected month passes without a credit.

When does an energy tariff reward get credited?#

There is no universal timetable because the reward terms differ by supplier. EDF currently says Power Perks credits are normally added during the first week of the month after an eligible event, once it has the smart-meter readings needed to calculate the credit.

When will EDF Power Perks credit appear?#

EDF currently says the credit will normally be added during the first week of the month after the Free Electricity event. It needs complete smart-meter readings from the event period, so missing or delayed data can hold up the calculation.

Why is my energy reward credit missing?#

Check the event date, your smart-meter readings and the scheme eligibility rules. A reward may be delayed because the supplier does not yet have complete usage data. If the expected credit date has passed, ask the supplier to trace the event and explain the calculation.

Is an energy account credit the same as cash?#

No. A tariff reward can be an adjustment to your energy account rather than money paid into your bank account. EDF says Power Perks credit is added to the EDF account and cannot be exchanged for cash or moved to another energy account.

Can I get ordinary energy account credit refunded?#

Usually yes, subject to the supplier’s assessment of the account. Ofgem says you can contact your supplier to claim ordinary credit back, but it is sensible to consider your future bills before requesting a refund, especially before higher winter usage.

What happens to energy credit when I switch supplier?#

Ordinary account credit should be dealt with in your final bill. Ofgem says your old supplier will refund credit in the final bill when you switch. A separate reward scheme can have different terms, so check whether the promotional credit is transferable or restricted to the original account.

What if my smart meter readings are missing?#

Contact the supplier and ask it to check the meter communications and whether it can obtain the missing readings. For schemes such as EDF Power Perks, complete readings are part of the credit calculation. Keep any event confirmation so the supplier can match the problem to the right period.
