5 Universal Credit Mistakes That Could Cost You Hundreds
1. Failing to Report Changes in Circumstances
Life changes. Maybe you got a job, moved house, split up with a partner, or had a baby. But if you don’t tell the DWP fast enough, you could be paid the wrong amount—and they will want that money back.
Here’s what you must report:
- Starting or stopping work
- Changes in income (even from self-employment or casual gigs)
- Rent increases or moving home
- Someone moving in or out of your home
- Becoming a carer or getting care
- Changes in your health or ability to work
Why it matters: If you don’t report the change quickly, you could face an overpayment, and the DWP will deduct money from future payments. You could even be hit with a sanction or accused of benefit fraud.
2. Missing Appointments or Failing to Meet Your Commitments
When you first claim Universal Credit, you sign something called a Claimant Commitment. It’s like a job-seeker’s contract. If you break it—by missing Jobcentre appointments, not applying for enough jobs, or failing to check in online—you could be sanctioned.
Real-life example: In one month alone, over 116,000 claimants lost some or all of their Universal Credit due to sanctions.
Avoid it:
- Set calendar reminders for Jobcentre visits
- Keep proof of job applications
- Speak up early if you’re struggling—your work coach can adjust your commitments
3. Providing Incorrect or Incomplete Information
Most people don’t lie—they just make mistakes. Maybe you typed in your income wrong, missed out some savings, or didn’t upload a document. Unfortunately, even a small slip can trigger an overpayment or delay your payments.
Tips to get it right:
- Double-check your earnings and rent info before submitting
- Upload all required documents—payslips, tenancy agreements, etc.
- If you’re unsure, speak to an adviser before submitting
Good to know: Over 686,000 Universal Credit overpayments last year were due to DWP or claimant error. You can appeal overpayments if you think it’s not your fault.
4. Not Updating Housing or Rent Costs
This is one of the most overlooked areas. If your rent changes but you don’t tell Universal Credit, your Housing Element could be wrong. That might mean you’re underpaid (missing out on support) or overpaid (which they’ll reclaim later).
Example: Your rent goes up in April, but you forget to update your online journal. By October, you’ve lost out on £600 in extra housing help.
Do this:
- Upload your new tenancy agreement or a letter from your landlord
- Log into your UC journal and select “Report a change in housing”
- Contact your work coach if it doesn’t update
5. Assuming You’re Not Eligible
This one might surprise you. Many people think, “I won’t qualify—I earn too much.” But Universal Credit is designed to top up low earnings, help self-employed folks, and support part-time workers or those with kids.
Even if you only get £10/month, you could unlock other benefits like:
- Free school meals
- Cost of living payments
- NHS prescriptions

If you’re self-employed or have irregular hours, UC uses something called the Minimum Income Floor (MIF). It assumes you’re earning minimum wage—even if you’re not. That can seriously reduce your payment.
Good news: You can ask for a start-up period (up to 12 months) when starting your business. During this time, the MIF won’t apply.
Tip: Keep accurate business records and speak to a work coach who understands small business income.
