If your Housing Benefit or the housing element of your Universal Credit has been cut because the rules say you have a bedroom you do not need, you can ask for that decision to be looked at again. The reduction is 14 per cent of your eligible rent for one spare bedroom and 25 per cent for two or more1. It applies to people under State Pension age who rent from the council or a housing association2.
If your Housing Benefit or the housing element of your Universal Credit has been cut because the rules say you have a bedroom you do not need, you can ask for that decision to be looked at again. The reduction is 14 per cent of your eligible rent for one spare bedroom and 25 per cent for two or more1. It applies to people under State Pension age who rent from the council or a housing association2.
The first step is a review by the council, and you normally have one month from the decision to ask for it3. If the review does not change the outcome, the next step is an appeal to an independent tribunal4. While you challenge, the reduction stays in place, so the rent shortfall still has to be met, and a Discretionary Housing Payment from your council can cover it temporarily5.
This page sets out what the reduction is, the grounds that actually work, how each stage of a challenge runs, and where free help is available.
What the removal of the spare room subsidy is and who it affects
The reduction is officially called the removal of the spare room subsidy, or the under-occupation penalty, though most people know it as the bedroom tax7. It is not a separate charge or a tax. It is a cut to the benefit that helps you pay rent, applied when your home has more bedrooms than the rules say your household needs8.
It affects people who rent council or housing association properties, and it applies to Housing Benefit or the housing costs element of Universal Credit for people under State Pension age2. If there is a spare bedroom in the home, you might not get enough money from benefits to cover the rent9.
The rules allow one bedroom for each of a set list of people. That includes you and your partner, every other adult in your home, any two children younger than ten, two children of the same gender older than ten, a non-resident carer, and two people who cannot share because of a disability10. A disabled child who gets the middle or higher rate care component of Disability Living Allowance and cannot share a room can also be counted11.
The reduction is worked out as a percentage of your eligible rent, not a flat sum. In one worked example, a household with one spare room and rent of £450 a month had a maximum monthly housing element of £3873. The gap between the two figures is what the household has to find from elsewhere.
Grounds for challenging a spare room decision
A challenge has to rest on the rules, not on hardship. You can challenge a decision if you think it is wrong according to the rules12. That means showing either that the council has counted your household wrongly, or that a rule that should apply to you has been missed.
The grounds that most often succeed are about who should be counted. A room is not treated as spare if you have been affected by domestic violence11. Living in a sanctuary scheme adapted property exempts you from the under-occupation charge13. Some disabled adults and children are exempt if they need their own bedroom because of their condition14.
There are also rules about couples and children who cannot reasonably share. One bedroom is allowed for every adult couple, or two rooms if it is inappropriate to share because of disability and one of you gets a qualifying disability benefit15. Two children under 16 of the same sex are expected to share one bedroom, unless it is inappropriate for them to share because of disability15. If you have a child who is not reasonably able to share a room because of their disability and they get the care component of Disability Living Allowance or Child Disability Payment at the middle or highest rate, an additional bedroom is allowed15.
One ground that does not work is room size. The size of the room does not affect whether you pay bedroom tax or not3. A small box room counts the same as a large one, so a challenge built only on the room being too small to be a bedroom will fail.
Asking for a mandatory reconsideration
If you disagree with the decision made on your benefit claim, you can ask for the decision to be looked at again. This is called a mandatory reconsideration16. It is the first step in challenging a decision, and it comes before any appeal12.
The process is the same in shape across benefits. Asking for a benefit decision to be looked at again is the definition of a mandatory reconsideration17, and it is part of the steps to challenge and appeal a benefit decision18. For Housing Benefit, the council can be asked to reconsider a bedroom tax decision within one month of receiving the decision19. For a refusal to accept that a child cannot share a bedroom, the options are to request a review or to appeal against that decision within one month20.
Put the request in writing and be specific. Say which decision you disagree with, the date on it, and which rule you believe has been applied wrongly. If the ground is disability, say which benefit is in payment and who receives it. If the ground is that a child cannot share, say why and name the benefit the child gets.
The council will look at the decision again and either change it or confirm it. If it confirms the decision, you can take the matter further. If you are still unhappy with the outcome, you can appeal to an independent tribunal4.
Appealing to a tribunal: how it works
You can ask for a review of a benefits decision if you think it is wrong3, and if the review does not resolve it, the appeal goes to an independent tribunal. The tribunal is separate from the council and from the Department for Work and Pensions, and it decides the case on the rules and the evidence.
The tribunal route is not the same for every kind of decision. For direct tax, such as income tax, you must appeal to HMRC or the Welsh Revenue Authority before you appeal to the First-tier Tribunal21. For indirect tax, such as VAT, you must either pay or deposit the tax in dispute, or make a hardship application, before submitting the appeal21. Those rules are about tax appeals and show how much the pre-appeal conditions vary between decision types.
For benefit decisions, the pattern is a review first and a tribunal second. Pension Credit decisions follow the same shape: if you are still unhappy with the outcome, you can appeal to an independent tribunal4. Rent increases can also be challenged at a tribunal, and your rent will not go up until the tribunal sets the rent22.
Prepare the case around the rule you say was misapplied. Take the decision letter, the review outcome, and evidence of the benefit that supports your ground, such as an award of Disability Living Allowance or Personal Independence Payment. If you think a benefit or tax credit decision is wrong, you may be able to try and get it changed23, and free advice services can help you put the case together24.
Do I have to keep paying my rent while I challenge the decision?
Yes. The reduction continues while the challenge is considered, so the shortfall between your rent and your benefit still has to be paid. The same principle applies to other bills: you must keep paying your Council Tax while you wait for a response to a challenge25.
Falling behind on rent in social housing can lead to arrears action, so it is worth telling your landlord that a challenge is under way and asking what they can offer in the meantime. Free debt advice services can help if arrears have already built up24.
A Discretionary Housing Payment is the main way to cover the gap while a challenge runs. You can apply for a DHP from your local council if you are affected by the bedroom tax and you cannot pay your rent or move to a smaller property5. If you are struggling to pay your rent as a result of the bedroom tax, you could apply to your local council for a discretionary housing payment26.
Be aware of how these payments work in practice. Discretionary Housing Payments are funded by a limited sum of money and most councils will not award them on an ongoing basis, so they may only be temporary help11. They are a bridge, not a permanent fix.
Discretionary Housing Payments while you challenge
A Discretionary Housing Payment is a top-up from your council, separate from Housing Benefit and Universal Credit. You apply to your local council for one27, and it is meant for people who cannot pay the extra rent or move to a smaller property11.
The decision on a DHP is discretionary, which changes how you challenge it. You can ask the council to review the decision, and each council has its own review process28. You can request a review if you have been refused a DHP, if you are not happy with the amount awarded, or if you are not happy with how long the payment lasts29.
There is a limit to what a review can achieve. If the council refuses to look at it again or does not change its mind, there is no legal right of appeal, although the council could be challenged if it has acted unreasonably when dealing with your claim30. That is a different and narrower route than a benefit appeal, and it turns on whether the council followed its own process fairly.
The practical approach is to apply early, before arrears build up, and to give the council the figures it needs: your rent, your benefit, the size of the shortfall and why moving is not possible. Because funding is limited and awards are often short, it is worth asking how long the payment will last and what happens when it ends.
Is there a different process in Northern Ireland?
Yes. In Northern Ireland the reduction is offset rather than simply applied. Help there is called an administrative welfare supplementary payment6, and it is intended to make sure that you do not actually lose any Universal Credit because of the bedroom tax6.
That means the practical effect for a claimant in Northern Ireland is different from the rest of the UK, even though the underlying size criteria are similar. For further information, contact the Welfare Changes Helpline on 0808 802 002011.
In Scotland and Wales the reduction applies as it does in England, and the challenge route runs through the council and then a tribunal. Where you live also affects which extra help is available: Discretionary Housing Payments operate in Scotland28 and in Wales30, and each council runs its own process. If you would like further support on your options in Scotland, Carers Scotland runs a helpline for guidance11.
What happens if my challenge succeeds?
If the challenge succeeds, the reduction is removed and your award is recalculated. In practice that means the amount taken off your Housing Benefit or Universal Credit housing element is restored, and any underpayment for the period covered by the decision should be corrected.
The outcome is not always a simple win, and it is worth knowing that. A challenge can go three ways: your band can go up, down, or stay the same31. That example comes from Council Tax band challenges, but the principle applies to benefit reviews too: asking for a decision to be looked at again can confirm it, change it in your favour, or occasionally change it in a way you did not expect.
If you took in a lodger to cover the shortfall, the treatment of that income matters. For Housing Benefit, you would not have to pay the bedroom tax but some of the money counts as income, which can affect your other benefits3. The government also runs a Rent a Room Scheme that allows you to earn some income from a lodger tax free32, though the interaction with means-tested benefits still has to be checked.
A successful challenge does not automatically clear rent arrears that built up while the reduction was in place. Ask the council or your landlord separately about how those are handled, and take advice if arrears action has already started.
Where to get free help with a challenge
Free help exists at every stage, and using it does not cost anything. If you think a benefit or tax credit decision is wrong, you may be able to try and get it changed23, and there are free advice services that can help24. Free legal help is also available at court through a duty adviser33.
For the bedroom tax specifically, the main sources of free guidance are the housing and disability charities. Scope publishes guidance on Housing Benefit and the bedroom tax3, Gingerbread covers it for single parents7, Carers UK explains it for people with caring responsibilities11, and Disability Rights UK sets out the size criteria rules in detail15. Contact covers the rules for families with disabled children20.
If money is the immediate problem rather than the decision itself, free debt advice is available24, and it can run alongside a challenge. For a Discretionary Housing Payment, the application goes to your local council27, and the council's own review process is the first route if the application is refused28.
Where a challenge is about a benefit decision, the practical steps are the same whoever you ask: keep the decision letter, note the one-month deadline, put the request in writing, and say which rule you believe was applied wrongly. Free advisers can help you draft that request and prepare for a tribunal if the review does not go your way.
