The cap means that if you or your partner does not work*, you will not get more in benefits than the average wage paid to people in work.
The benefit cap applies to households* in receipt of DWP benefits. The weekly amount of the cap is £257.69 for single people and couples without children and £384.62 for families.
If your total income including Housing Benefit is greater than this figure your Housing Benefit will be reduced so your income is below the above amount.

· Working Tax Credit (WTC)

· Attendance Allowance (AA)
