Jot down a few questions to make the most of your conversation.
Can you claim interest on overpaid amounts?
Yes, in some cases you may be able to claim interest if you have overpaid money to a business, lender, landlord, employer, or public body. The key question is whether the overpayment was caused by an error, delay, or unfair charge, and whether the other party has had the use of your money.
Interest is not automatic in every case. Whether you can claim it depends on the circumstances, the contract involved, and whether the overpayment has already been refunded.
When interest may be payable
You may have a stronger claim where the other side kept your money for a period of time after it should have been returned. For example, this can happen with tax overpayments, utility account credits, loan overpayments, or duplicated payments.
Sometimes interest is included in a refund or compensation offer. In other cases, you may need to ask for it separately. If the overpayment arose from an unlawful charge or miscalculation, interest may also be claimed as part of putting you back in the position you should have been in.
How the amount of interest is worked out
The amount of interest depends on the type of claim and the period the money was held. It may be based on a contractual rate, a statutory rate, or what a court considers fair in the circumstances.
For court claims in England and Wales, interest is often claimed under the County Courts Act 1984 in some debt-related disputes. In other situations, businesses may use their own complaints process or apply a different rate when settling a complaint.
What to do if you have overpaid
Start by checking your records and confirming how much was overpaid and when. Keep copies of statements, invoices, correspondence, and any evidence showing the payment should not have been taken.
Then contact the organisation and ask for a refund and any interest you believe is due. Be clear about the dates, the amount, and why you think interest should be paid. If they refuse, you can escalate the complaint or consider legal advice.
Limits and practical points
There may be time limits for bringing a claim, so it is sensible to act quickly. In some cases, a claim for interest may only succeed if the overpayment itself is accepted as due back to you.
It is also worth checking whether the overpayment has already been offset against another debt. If so, interest may be calculated differently, or not apply at all.
Getting help
If the amount is significant or the rules are unclear, consider speaking to a solicitor or a free advice service. This can be especially useful where the claim involves tax, lending, employment, or a regulated financial product.
A well-documented complaint often improves your chances of recovering both the overpayment and any interest. The more clearly you can show what happened, the easier it is for the other side to assess your claim.
