Your council will usually ask for proof of identity, National Insurance number, address, household members, income, benefits, savings and other capital. You may also need your tenancy agreement or rent statement, showing the landlord’s details, rent and any services included. Provide recent bank statements, payslips or benefit letters if requested, and explain any missing documents when you apply. Housing Benefit is generally claimed through your local council, although many working-age people must claim Universal Credit instead; check the official GOV.UK guidance or your council’s website for the current rules.
