Common mistakes include applying as single when you live with a partner, failing to report earnings or changes in your circumstances, and overlooking savings or other capital. You should also check whether your immigration status, age, education or housing situation affects eligibility, as the rules can be detailed. Give complete and accurate information when you claim and report changes promptly through your Universal Credit account. Check the latest guidance on GOV.UK, because the Department for Work and Pensions decides eligibility based on your individual circumstances.
