- Report them now in your Universal Credit account. If you tell DWP late, you can be paid too much, and you then get less UC each month until the overpayment is paid back.1
- Any UC paid above what you were entitled to can be recovered, whoever made the mistake.2
- Where the mistake was about savings and lasted 3 months or more, DWP must treat your savings as going down by the UC overpaid in each 3 months, which makes the overpayment smaller.34
The rules
Section 71ZB of the Social Security Administration Act 1992: DWP “may recover any amount of” Universal Credit “paid in excess of entitlement”, once the award has been revised or superseded.2
Regulation 7 of the Social Security (Overpayments and Recovery) Regulations 2013, the diminution of capital rule: at the end of the first 3 months of the overpayment period, the capital is treated as reduced by the UC overpaid in those 3 months, and again at the end of each later 3 months. It is used only to work out the overpayment.34
A civil penalty of £50 can be added where you negligently gave wrong information, did not take reasonable steps to correct it, and that caused an overpayment.4 You may be prosecuted if you deliberately give false information.15
Worked example: £17,000 not declared for 6 months
A single person aged 25 or over with £500 rent was paid £924.90 a month for 6 months, but had £17,000 in savings they had not declared. With more than £16,000 they were not entitled to any UC.
| Months 1 to 3: UC due on £17,000 | £0.00 a month |
| Months 1 to 3: overpaid | £2,774.70 |
| Savings treated as reduced to | £14,225.30 |
| Months 4 to 6: UC due on £14,225.30 | £781.35 a month |
| Months 4 to 6: overpaid | £430.65 |
| Without the 3-month rule | £5,549.40 |
| Overpayment with the rule | £3,205.35 |
Between £6,000 and £16,000 the UC due is cut by £4.35 a month for each £250 (or part of £250) over £6,000.9 The real savings are unchanged; the reduction is only for working out the overpayment.3
Will DWP find out?
DWP sent its first Eligibility Verification Notice to banks in October 2026, asking them to flag accounts where data suggests benefit rules may not be met, such as undeclared savings. It starts with a test-and-learn phase.7
Banks can share account holders' names, account details, balances and the dates of transactions abroad, not full statements.6 A notice cannot ask for data more than a year old, but it can ask for the date an account first went over the savings level DWP set.8
A flag is not a decision: DWP staff review the claim and you can be asked for information.6
What to do now
Report the savings in your UC account under money, savings and investments.1
If you get an overpayment letter and think it is wrong, ask for a mandatory reconsideration, usually within one month of the letter.5
Keep statements showing what you had and when. If you were under £16,000 for part of the time, the overpayment is smaller.9
Common mistakes
Spending the savings quickly before reporting. Spending to get or keep UC can be treated as deprivation of capital.1
Assuming the overpayment is every penny of UC paid. For savings errors of 3 months or more the diminution rule must be applied.3
