The benefit cap was introduced in April 2013. It was initially applied to HB and subsequently to UC, as UC was gradually rolled out. UC replaces 6 means-tested benefits including HB and since December 2018, UC has been available across Great Britain (GB) to people applying for means-tested social security support. However, a small number of the population may still apply for HB. Read about who can get HB. DWP is in the process of moving all legacy benefit claimants to Universal Credit.
