The bedroom tax is one of the benefit rules older tenants worry about most, and one that applies to them least. Whether it touches a particular household turns almost entirely on age, and on the age of a partner.
What the bedroom tax is
In a council or housing association home, the regulations reduce the eligible rent used to work out Housing Benefit by 14% where the home has one more bedroom than the household is entitled to, and by 25% where it has two or more (Housing Benefit Regulations 2006, regulation B13, checked 14 September 2026).
The official name is the removal of the spare room subsidy, and it applies to the social rented sector only. Private tenants are assessed under a different system, the local housing allowance, which has its own size rules and is not what people mean by the bedroom tax.
Why pension-age claimants are outside it
The reduction is written into the Housing Benefit regulations for people below State Pension age. The separate regulations for claimants who have reached the qualifying age for Pension Credit contain no equivalent rule (Housing Benefit (State Pension Credit) Regulations 2006, regulation 13, checked 1 November 2026), so a pension-age claim is not subject to this reduction.
In practice, a single person over State Pension age, or a couple who have both reached it, can stay in a home with spare bedrooms without their Housing Benefit being cut for them. Our Housing Benefit guide covers who still claims pension-age Housing Benefit and how it is worked out.
The exception: mixed-age couples
The exemption does not always reach a couple where only one partner has reached State Pension age. GOV.UK says you cannot make a new claim for Housing Benefit if you have reached State Pension age but your live-in partner has not, unless you had an existing claim as a couple before 15 May 2019 (GOV.UK, Housing Benefit: eligibility, checked 1 November 2026).
A mixed-age couple making a new claim is therefore usually directed to Universal Credit, which is a working-age benefit with its own rules on housing costs. Before relying on the pension-age exemption, check which benefit the claim is actually under, and ask how spare bedrooms are treated on that claim. The same 15 May 2019 date governs Pension Credit, covered in Pension Credit and couples.
How many bedrooms a household is allowed
Where the rule does apply, the calculation starts from a bedroom entitlement. The regulations allow one bedroom for a couple, one for each other adult, one for two children of the same sex, one for two children under ten, and one for any other child (regulation B13, checked 14 September 2026).
A room counts as a spare bedroom if the household has more than that. Rooms used as a study or a store still count as bedrooms if they are bedrooms, which is why the definition of the property matters as much as the family.
Extra bedrooms for care and disability
The regulations make room for care and disability in two ways. An additional bedroom is allowed where a person in the household requires overnight care, and a couple or a child who cannot share a bedroom because of a disability is counted as needing a bedroom of their own (regulation B13 and GOV.UK, Housing Benefit: what you'll get, checked 1 November 2026).
Foster carers are covered too. GOV.UK says one spare bedroom is allowed for an approved foster carer between placements, for up to 52 weeks from the end of the last placement, and for a newly approved foster carer for up to 52 weeks if no child has yet been placed (GOV.UK, Housing Benefit: what you'll get, checked 1 November 2026). Evidence is needed for each of these, so ask the council what it wants.
If your help with rent has been cut
Check first whether the cut was applied to the right kind of claim. A pension-age Housing Benefit claim should not carry a spare room reduction, so a letter applying one is worth querying straight away. Ask the council which regulations it applied, and from what date the claim began.
Where the reduction does apply and cannot be avoided, councils can make discretionary housing payments to help with a shortfall. Scotland goes further: the Scottish Government says it is committed to fully mitigating the removal of the spare room subsidy, and expects anyone affected who applies for a discretionary housing payment to receive one (gov.scot, checked 1 November 2026). Ask the council for one in writing, explaining the circumstances, and ask for a reconsideration of the benefit decision itself if you think the bedroom count is wrong. Our page on Housing Benefit overpayments covers what happens if the council later says too much was paid.
