The benefit cap is a limit on the total amount of benefit you can get. It applies to most people aged 16 or over who have not reached State Pension age.
The amount your household gets from some benefits might go down to make sure you do not get more than the cap limit.
The benefit cap affects:
Child Tax Credit
Employment and Support Allowance
Severe Disablement Allowance
Widowed Parent’s Allowance (or Widowed Mother’s Allowance or Widow’s Pension if you started getting it before 9 April 2001)
