Common mistakes include failing to report changes in your income, rent, address or household, sending incomplete evidence, and assuming Housing Benefit will start automatically. Check whether you should claim Housing Benefit or Universal Credit, as most working-age people make new housing-cost claims through Universal Credit, with exceptions such as some supported or temporary accommodation. Claim promptly through your local council and check whether non-dependant deductions or an overpayment may affect your award. Keep copies of forms and letters, and contact the council or check GOV.UK if you are unsure about your circumstances.
