A couple with children may qualify for help with rent, but whether this is Housing Benefit or Universal Credit depends on their circumstances. Most working-age couples make a new claim for Universal Credit, including its housing costs, while Housing Benefit remains relevant in some situations, such as living in supported or temporary accommodation or being of State Pension age. The council will consider income, savings, rent, household size and local benefit rules, and the benefit cap may affect the amount. Check the official GOV.UK guidance or ask your council which claim to make.
