A pension overpayment means your scheme, or DWP for the State Pension, has paid you too much. You usually have to repay it, though plans and defences exist.
Whether the money has to go back depends on who paid it, why, and how long ago. What follows is an outline, not legal advice. Clawing back an overpaid sum can dent what you planned to live on. Ask an FCA-authorised adviser about that dent, with nothing to pay, using the form on this page to book the conversation.
What is a pension overpayment, and how does it happen?
The Pensions Ombudsman (TPO) puts it simply: "An overpayment happens when a pension scheme pays too much money to a member or other beneficiary." Its examples of causes are employers giving the scheme wrong information, administrative mistakes and changes in your circumstances that were never passed on.
DWP's staff guide on benefit overpayments, which covers the State Pension among many other benefits, separates two broad causes. In one, you were paid something you were not entitled to because a fact was not reported or was reported wrongly. In the other, DWP made the mistake.
Money that reaches an account after the pensioner has died is a different situation, with different people asked to repay. That is covered in pension overpayment after death. This page is about a pension paid to you while you are alive.
Do you have to pay back a pension overpayment?
Usually yes, even when the mistake was not yours, although the defences further down can reduce or remove the sum. TPO explains that a member is only entitled to benefits properly calculated under their scheme's rules, so being blameless does not let you keep the extra or carry on receiving it.
Two things follow. An incorrect pension will almost always be reduced to the correct figure going forward. And the scheme "will usually take steps to recover the overpaid amount – for example, by deducting amounts from your future pension payments over a period of time, or asking you to repay a one-off lump sum."
For occupational schemes, section 91 of the Pensions Act 1995 generally stops a pension being charged or set off against, but one listed exception covers a debt owed to the scheme from a payment made in error in respect of the pension. The scheme must give you a certificate showing the amount and its effect on your benefits. If you dispute the amount, the set-off cannot be used until you and the scheme settle it, the Ombudsman has made a determination, or a court order or arbitration award makes the debt enforceable.
That section concerns occupational schemes. A personal pension or other arrangement may rest on its own terms, so ask the provider what it relies on. For who decides in a trust-based scheme, see what pension trustees do.
Is a State Pension overpayment treated differently?
In several ways. DWP's guide lists State Pension and new State Pension among the benefits it can recover under social security law, and it says a Decision Maker makes an overpayment decision before recovery action begins. That decision places the overpayment in a category, and the category matters.
Where the cause was a misrepresentation or failure to disclose, DWP can recover the payment, and the guide adds that these terms "apply to both innocent errors and omissions and deliberate fraud", so an honest oversight can fall in this group. Where the cause was DWP's own error inside a valid award, the guide says the overpayment "is written off". Money paid outside the award, such as a duplicate payment, a regular £50 that arrived as £500, or payments that carried on after you were told the award had ended, can be pursued as restitution. DWP's policy is to ask for that money back where you could reasonably have been expected to know you were overpaid. Which category applies to you is for DWP to say, so ask it to explain its decision.
You can challenge the decision. A request for mandatory reconsideration should be made within one month and one day of the day after the decision notice was issued. If recovery has begun, it is suspended until the reconsideration is finished, and if DWP does not change its decision there is a right of appeal. DWP can also deduct from a different benefit than the one overpaid; the guide's example is an Income Support overpayment recovered from a Retirement Pension. It sets a "SMOP limit" of £65 for general overpayments, below which it treats the full process as not cost-effective.
For the benefit itself, see the State Pension explained; Pension Credit is on DWP's list too.
Can you repay a pension overpayment in instalments?
Often, and TPO expects you to ask. It says to tell the scheme about any concerns or difficulties in repaying, because that helps it choose how to recover the money, and that in most circumstances you and the scheme should be able to agree how and over what period.
DWP's guide is similar. Its policy is to recover debts as quickly and cost-effectively as it can without causing undue hardship. For people no longer on benefit, it says an instalment plan is negotiated where a lump sum is not possible, with the rate set by ability to repay and ideally clearing the debt within 2 years. If a rate proves unaffordable, the options include a temporary suspension, a lower rate or, in exceptional cases, writing the debt off.
Keep a record of when you were told and what you were told. A longer plan eases each month but runs for years, so your State Pension and private pots may deserve a fresh look. Weighing that against the rest of your retirement money is the kind of work an FCA-authorised adviser does, and one will ring you, free, after your name and number go into the short form here.
What defences can stop a scheme recovering an overpayment?
TPO summarises three legal defences, and stresses that they "occur in very specific circumstances that largely do not relate to whose fault the error was." Each applies only if you can show all of its conditions with evidence; without evidence a defence is unlikely to succeed.
- Change of position. You spent the extra without knowing you were not entitled to it, and with no reason to know; it went on things you cannot sell or recover money from; you would not have spent it that way had you known; and repaying would be unfair.
- Estoppel. The scheme did something that led you reasonably to believe your pension was correct, you made irreversible financial decisions relying on it; you would suffer if you now had to repay; and repaying would be unfair. TPO warns that "Pension estimates alone usually aren't enough to qualify for this defence." Information marked as not final or binding is unlikely to count.
- Delay, or laches. The scheme knew about the overpayment but delayed telling you, and the delay cost you something. You may then not have to repay what was overpaid during the delay.
Evidence can include receipts showing what the money went on, benefit statements and scheme correspondence, and bank statements or payslips. The scheme should explore these defences through its internal dispute resolution procedure (IDRP), its formal complaints route, so raise them in writing.
How long can a scheme or DWP wait before asking for the money back?
For a scheme claim in England and Wales, usually six years from each payment, though the clock can start late; DWP has no time limit there on deductions from benefit. TPO says "There are also legal time limits in which the scheme can make a claim to recover the overpayment from you." In a 2018 determination (PO-18796) the Ombudsman put the usual limit at six years from the incorrect payment, under section 5 of the Limitation Act 1980, adding that under section 32 time does not start until a mistake was discovered or could "with reasonable diligence" have been discovered. In another (PO-18629) it treated deductions from future pension, called recoupment, as outside the six-year limit. Each case turns on its facts, so how the limits apply to you is a legal question.
Scotland has its own law: section 6 of the Prescription and Limitation (Scotland) Act 1973 extinguishes obligations of the kinds it covers after five years without a relevant claim or acknowledgement, and Schedule 1 lists among them obligations based on redress of unjustified enrichment, including restitution and repetition.
DWP's guide has its own timetable. For civil action in England and Wales there is an overriding limit of 6 years, counted from the latest of dates that include the overpayment decision, any written acknowledgement of the debt and any voluntary repayment. Other than civil action, it states, "there are no time limits for recovery of a benefit debt" in England and Wales, so deductions from benefit are unaffected. For Scotland it gives 20 years from the overpayment decision for civil action.
What does the Pensions Ombudsman do about overpayments?
TPO is the last step, not the first. It expects you to raise concerns formally in writing and use the scheme's IDRP. Only if that ends without agreement can you complain to TPO, which asks for the scheme's final response and any evidence for a defence. The Pensions Ombudsman page explains how a complaint is made.
There is a deadline. In most cases TPO wants the complaint within three years, counted from the later of the event itself and the point you knew, or reasonably ought to have known, something was wrong. It can sometimes extend that where something stopped you complaining sooner, and it notes that the Limitation Act 1980 can still affect what it can consider.
If the scheme offers an award for distress and inconvenience, TPO says "Any award made might be offset against the overpayments to reduce the amount to be recovered." A DWP overpayment decision follows the reconsideration and appeal route above rather than IDRP.
Smaller questions about an overpaid pension
Does it matter that the error was the scheme's?
Fault alone does not remove the debt, according to TPO. It can matter indirectly, since delay and misleading statements by the scheme are what the laches and estoppel defences look at. DWP separately treats its own errors inside a valid award as written off.
What if I have already spent the money?
Spending it is not enough by itself. The change of position defence needs good-faith spending on things that cannot be recovered, shown with documents.
Is this the same as emergency tax on a pension withdrawal?
No. An overpayment is pension paid beyond your entitlement, while emergency tax is tax withheld from a withdrawal, which claiming a pension tax refund deals with.
Can someone deal with the scheme for me?
A power of attorney, if one is in place, can let a trusted person act; see pensions and power of attorney. The free routes for pension help are set out in free pension advice.
Before you reply to the letter
Work through it in order: what the scheme says went wrong, how it plans to recover the money, whether any defence fits your facts, and whether a time limit has passed. Keep copies of everything and put your points in writing.
