Am I overpaying for energy?
Use this page to spot common overpayment patterns and estimate the gap between your current monthly bill and a more competitive benchmark.
Short answer
You might be overpaying if your fixed term ended, your direct debit keeps building excess credit, or your tariff rates are no longer competitive for your usage.

Common signs you are paying too much
- Your fixed deal ended and no recent tariff review has happened.
- Direct Debit rose but annual usage did not rise similarly.
- Large credit keeps accumulating without a clear seasonal reason.

Not every high payment means overpaying
- Seasonal credit can be normal if it balances through winter.
- Higher usage months can raise cost even on a fair tariff.
- A low monthly payment can hide underpayment and future catch-up risk.
- Judge value over annual totals, not one month in isolation.
| Signal | Likely next action |

Energy overpaying questions
Is a credit balance always bad?
Not always. Some credit is seasonal. The issue is persistent excess versus your annual usage and payment profile.
Should I compare by monthly payment only?
No. Compare annual cost using rates, standing charges, and usage to avoid misleading conclusions.
Can I be overpaying even with low usage?
Yes. Low usage does not protect you from poor tariff rates or high standing charges.
When is switching usually worth it?
When annual savings remain clear after accounting for term, fees, and plan fit.
I am moving soon. Should I still switch now?
If your move is near, prioritise flexibility and align decisions with your move-home schedule.
