What the benefit cap is and who it affects
The benefit cap is a limit on the total amount the government will pay to a single working-age household from most means-tested and income-replacement benefits. It applies to families and to single people without children, though the cap level differs. In 2026/27, the cap for families (or single people with a child who qualifies as a dependant) is £442.31 per week (£23,000 per year) in Greater London and £376.38 per week (£19,572 per year) outside London. For single adults without dependants it is lower: £296.35 per week in London and £251.77 outside.
The cap is applied by reducing UC. DWP first calculates what your total UC award would be without the cap, then adds up all your capped benefits, and if the total exceeds the cap level, UC is reduced by the difference. The cap does not reduce other benefits directly, it only comes off UC. If you are not on UC but on Housing Benefit and other benefits, Housing Benefit is reduced instead. The cap is not a deduction from a specific element, it can, in principle, reduce UC to zero if the combination of other capped benefits is high enough.
Which benefits count towards the cap total
The following benefits are included in the cap calculation: Universal Credit (all elements), Housing Benefit (for those not yet on UC), Child Benefit, Child Tax Credit, Working Tax Credit (if in payment below the working threshold), Bereavement Allowance, Widowed Parent's Allowance, Widowed Mother's Allowance, Widow's Pension, Maternity Allowance, Incapacity Benefit, Severe Disablement Allowance, and income-based Jobseeker's Allowance.
Benefits that are NOT counted and therefore do not push you over the cap include: Personal Independence Payment (PIP), Disability Living Allowance (DLA), Attendance Allowance, Carer's Allowance, the UC limited capability for work-related activity (LCWRA) element when exempt status is confirmed, contributory ESA (when paid with the support component), Industrial Injuries Disablement Benefit, and War Pensions. If you receive one of these non-capped benefits you may also be entirely exempt from the cap, see the exemptions section.
Exemptions: who is not subject to the benefit cap
You are completely exempt from the benefit cap if you or your partner receive any of the following: Employment and Support Allowance (ESA) with the support component; Personal Independence Payment (daily living component or mobility component at any rate); Disability Living Allowance (care or mobility component at any rate); Attendance Allowance; Industrial Injuries Disablement Benefit; War Pension; or Carer's Allowance. For most of these, the exemption applies from the date the qualifying benefit is in payment, not from when you apply for it, so making a successful PIP claim will remove the cap retroactively to the PIP award date.
The working exemption is also significant. If you or your partner are working and earning at or above the equivalent of the Working Tax Credit (WTC) earnings threshold, approximately £722 per month in net earned income for UC purposes, you are exempt from the cap. This is specifically designed so that working families do not face the cap. For UC claimants, this threshold is assessed from the actual monthly earnings reported in your assessment period, not an annual average. A month in which earnings dip below the threshold could temporarily expose you to the cap.
There is also a nine-month grace period if you were previously exempt due to working or WTC and then lose that exemption. If you or your partner was continuously employed for 12 months before falling below the earnings threshold, the cap will not apply for the following nine months. This gives time to find new work or alternative income before the cap bites.
How the cap is applied in practice and how to challenge it
When DWP applies the cap to your UC, they reduce the standard UC calculation by the amount your total capped benefits exceed the cap level. The reduction hits the UC housing cost element first, because DWP's view is that housing is the most flexible element. Once the housing element is reduced to zero, any remaining cap reduction comes off the standard allowance and other elements. This can leave households with zero housing support while still receiving small amounts of other UC elements.
If you believe the cap is being applied incorrectly, you can challenge it via a Mandatory Reconsideration (MR). Common reasons a cap decision may be wrong: a household member has a qualifying disability benefit in payment that was not reflected; your earnings crossed the working threshold but the assessment period earnings data was incorrect; a household member was incorrectly included or excluded; or the cap level was applied at the wrong rate (London vs outside London). Always check the decision letter carefully and contact your local Jobcentre Plus or a welfare rights adviser if anything seems off. Citizens Advice can help you prepare an MR.
