Supplementary Benefit was a means-tested benefit in the United Kingdom, paid to people on low incomes, whether or not they were classed as unemployed, such as pensioners, the sick and single parents. Introduced in November 1966, it replaced the earlier system of discretionary National Assistance payments and was intended to 'top up' other benefits, hence its name. To qualify a claimant had to demonstrate that their capital was below the limit, £6,000, and that their weekly income was less than their requirements, as calculated in accordance with the benefits regulations.
