Claimants can also get additional funds through the scheme if they have a severe disability or care for another adult.
Extra support is also available for those who are responsible for children or young people, or have certain housing costs.
Pension Credit also acts as a “gateway” benefit that provides access to other Government support, including cost of living payments for this winter.
People on the benefit can get the Cold Weather Payment, a £25 payment paid to Britons when temperatures drop below, or are forecast to drop below, freezing.
