Moving to Universal Credit from legacy benefits

Universal Credit is replacing six older benefits, known as the legacy benefits: Income Support, income-based Jobseeker's Allowance, income-related Employment and Support Allowance, Working Tax Credit, Child Tax Credit and Housing Benefit¹. The move of people still on those benefits, called managed migration, began in October 2023². By the end of June 2026, migration notices had been sent to 2.4 million individuals in 1.8 million households¹.

If you are still getting one of these benefits, the official position is that no action is needed until a letter, called a Migration Notice, arrives telling you it is time to claim³. That letter sets a deadline, normally three months, and claiming by that deadline is what unlocks transitional protection, a top-up that stops income falling when the move happens³. Tax credits and Income Support have already closed altogether⁴, and the remaining legacy benefits are being wound down on a timetable that runs to 2028 for income-related ESA claimants.

Which benefits Universal Credit replaces

Universal Credit is a single monthly payment for working-age people on a low income, and it is absorbing six older benefits into one¹. The full list is Income Support, income-based Jobseeker's Allowance, income-related Employment and Support Allowance, Working Tax Credit, Child Tax Credit and Housing Benefit¹. For most people these were replaced from 6 April 2025⁴.

Not everything moves across. Two benefits that will not move to Universal Credit are New Style Jobseeker's Allowance and New Style Employment and Support Allowance, which are contribution-based payments based on your National Insurance record³. If you are only getting one of those, you stay where you are. The rules also differ for people over State Pension age, who claim Pension Credit rather than Universal Credit, and for mixed-age couples, where the age of the younger partner determines which benefit applies.

The timetable matters because it is not the same for every benefit. Tax credits and Income Support have already closed⁵. Income-related ESA claimants are scheduled to move later, with those getting income-related ESA only, or income-related ESA alongside Housing Benefit, due to be migrated by 2028. Housing Benefit also continues for people in specified accommodation, covered below.

Tax credits and Income Support have already closed

If you were expecting to wait years for a letter, the position for two of the six benefits has already passed. Tax credits have now ended: you cannot make a new claim for Child Tax Credit or Working Tax Credit, and the official guidance says you may be able to get Universal Credit or Pension Credit instead⁵. Working Tax Credit and Child Tax Credit have been replaced by Universal Credit, and it is no longer possible for anyone to make a new claim for either⁷.

Income Support has closed as well. Official documents have removed references to Income Support, and to income-based Jobseeker's Allowance, following the closure of those benefits and the migration of claimants to Universal Credit⁴. The statistics tell the same story: November 2025 was the final release of Income Support statistics, because volumes are now minimal and will not increase⁸. In Northern Ireland there are no current Income Support claimants at all, following the completion of migration to Universal Credit⁹. At November 2025 there were just 10 Income Support claimants there, a fall of 100% (5,690) since November 2024².

What this means in practice is that anyone who would once have claimed Income Support, for example a carer or a lone parent, now claims Universal Credit from the outset. New claimants on a low income can no longer apply for Income Support and must apply for Universal Credit instead². If you were getting Income Support until recently, letters about your move, or about money you may owe, will come through the Universal Credit system.

The Migration Notice: what the letter asks you to do

The letter that starts the move is called a Migration Notice. You will receive it when your benefit is ending and it is time for you to claim Universal Credit³. The Department for Work and Pensions sends it, or in Northern Ireland the Department for Communities, and it asks you to claim Universal Credit by a deadline date printed on the letter¹⁰. That deadline is normally three months from the date of the notice³.

The deadline is the single most important thing on the page. It is the date your legacy benefits will stop coming in if you do not claim Universal Credit¹⁰. It is also the gate to transitional protection: you can only get that top-up if you have received a Migration Notice and you claim within the three-month deadline on your letter³.

The scale of the exercise is large. By the end of June 2026, 2.4 million individuals in 1.8 million households had been sent a migration notice¹. In Northern Ireland, 79,950 notification letters had been sent by the end of May 2025, inviting legacy benefit claimants to begin their move¹¹. If you have not had a letter yet, that is not a sign you have been missed: the notices are being issued in waves by benefit type.

One group gets special treatment. Full-time students who were participating in a course of education before claiming can be eligible for Universal Credit if they received a Migration Notice telling them to move¹². Without that notice, students face much tighter rules, so the letter itself changes what a student can claim.

Moving because your circumstances changed

Not everyone waits for a letter. A change in your circumstances can end your legacy benefit and force a move to Universal Credit before managed migration reaches you. This is known as natural migration, and it works very differently from the letter route.

Circumstances that can trigger a move include becoming a single parent while getting Jobseeker's Allowance, starting to need help with rent when you do not already have Housing Benefit, or moving to a new local authority area, and getting Income Support when your youngest child turns 5¹⁰. Other triggers are starting or stopping work of 16 hours or more per week, becoming responsible for your first child, renting for the first time, or separating from a partner you claimed benefits with¹³. For Income Support claimants, a significant change such as working more hours, finishing full-time education, or stopping being a full-time carer means being asked to move to Universal Credit¹⁴.

People who get a legacy benefit alongside a Severe Disability Premium may also move to Universal Credit after a change in circumstances¹⁵. Once you are on Universal Credit, the reporting duties are wider than on the old benefits: you must tell the DWP about changes to your health condition, becoming too ill to work, rent and earnings changes, finding or finishing a job, caring responsibilities, having a child, moving in with a partner, address changes, going outside the UK, changing bank details, and changes to savings, investments or immigration status¹⁶. The DWP will tell you if a change means you are no longer eligible; you do not need to cancel your claim yourself¹⁶.

The critical point is that a move triggered by a change of circumstances does not carry transitional protection¹⁷. That is the trade-off: waiting for the letter preserves your income level, moving early does not.

Transitional protection keeps you from losing money on the move

Transitional protection is the mechanism that stops the move cutting your income. It is a top-up award which ensures you are not financially worse off when your benefits are moved onto Universal Credit¹⁷. If your Universal Credit payment works out less than your current legacy benefit entitlement, you will automatically receive transitional protection to top it up¹⁷. In plain terms, your Universal Credit amount will not be less than what you were already getting¹³.

The award is automatic: you do not apply for it separately, and it is worked out when your Universal Credit claim is assessed¹⁷. For people moving with a Severe Disability Premium, official guidance is explicit:

To be eligible, three conditions must all hold: you apply only once you have received your letter, you apply before the deadline date in that letter, and you have no changes in your circumstances³. It is not a loan or a debt and you will not be asked to repay it³. The dedicated page on transitional protection goes into the detail, and how Universal Credit is worked out explains the elements the top-up sits on top of.

Who does not get transitional protection

Transitional protection is deliberately narrow. It is not available if you migrate from legacy benefits to Universal Credit because of a change in your circumstances, or if you make a new claim¹⁷. It only applies if you are an existing legacy benefit claimant with no changes in your circumstances¹⁷. If you choose to move to Universal Credit before being invited by the DWP, you will not receive any transitional protection¹⁰. The same applies if a move was triggered by a change in your circumstances rather than by a letter¹⁰.

This is why the official advice is to wait for your Migration Notice³. Claiming early is a voluntary act, and the system treats it as one: the top-up exists to compensate people who were moved by the government, not people who chose to move. If you have to make a new claim for Universal Credit because of a change of circumstances, transitional protection is not available⁹.

There is also a gap in the rules that has drawn comment. A Northern Ireland Assembly committee paper on the two-child limit legislation notes there is no provision in the Bill to protect existing claimants whose transitional element is eroded by additional child elements¹⁸. In other words, the top-up does not grow to reflect children added after the move, which can leave some families worse off than their pre-move position as their household changes.

How transitional protection shrinks or stops

Transitional protection is not fixed for life. It continues unless your Universal Credit entitlement increases or you have a significant change in circumstances¹⁷. If your Universal Credit entitlement rises, the transitional protection is reduced by the same amount, and this continues until the top-up reaches zero¹⁷. So annual uprating, a new element, or a change that adds to your Universal Credit eats the top-up rather than adding to your income.

A significant change in circumstances has a harsher effect: the transitional protection ends immediately, and the Universal Credit award drops to the amount payable without it¹⁷. Once transitional protection has ended, it is not applied to any future Universal Credit claim¹⁷.

The legislation sets out further ways the top-up can cease. Under the Universal Credit (Transitional Provisions) Regulations 2014, transitional protection can end where there is a drop in earnings over a three month period, or where an award ends, including where a couple separate or form¹⁹. Northern Ireland's regulations add a rule for people migrated from tax credits who have reached the qualifying age for Pension Credit: transitional protection ceases after the first 12 assessment periods where the claimant's or couple's combined earned income is below the National Minimum Wage rate for 16 hours a week for the third consecutive assessment period²⁰.

Some transitional amounts are fixed figures in the rules. For joint claimants whose first assessment period begins on or after 6 April 2026, the transitional SDP element is £502.27 where the higher severe disability premium rate was payable, £353.44 where it was not and the limited capability for work related activity element is not included for either claimant, and £148.82 where that element is included for either claimant⁶.

Claiming before the deadline and what happens to your old payments

When you claim Universal Credit, any benefits it replaces will stop³. Your first Universal Credit payment arrives about five weeks after you claim, and payments then come twice a month²¹. That gap between your last legacy payment and your first Universal Credit payment is the practical problem most movers face.

There are bridges for it. People moved to Universal Credit because their current benefit is ending can claim a Universal Credit New Claims Grant once their current benefit payments have ended, including the extra two weeks normally paid, known as the two week run-on²². Any grant is normally paid for the period from the date you apply to the day before your next income payment is due²². You can also ask for an advance on your first payment: before getting one you will need to give details of your bank or building society account and prove your identity²³. An advance is a loan: you will need to pay it back, and money will be taken off your Universal Credit payments until it is paid off²⁴. Universal Credit may agree to extend the repayment deadline by up to three months for a new claim advance if you are struggling with money²⁵.

If your Universal Credit claim ends, for example because your income rises, you may be able to restart without a fresh claim: if it has been six months or less since your last Universal Credit payment, you will automatically start getting payments again after your income decreases²⁶. Repayments of advances continue even after a claim ends, taken by other means such as other benefit payments, your wages or through a debt collection agency²⁷.

Income-related ESA and Housing Benefit

Income-related Employment and Support Allowance is on a later timetable than the benefits that have already closed. It has been replaced by Universal Credit for new claims: Universal Credit began to replace income-related ESA from May 2016 and became the benefit for all new claims from December 2018²⁸. The official ESA claim form consultation states plainly that income-related ESA has been replaced by Universal Credit²⁹. Existing claimants are being moved by managed migration, with those on income-related ESA only, or with Housing Benefit, scheduled to move by 2028.

Housing Benefit is the one legacy benefit that survives in a corner of the system. People in specified accommodation, certain supported and temporary housing, continue to claim Housing Benefit rather than the Universal Credit housing element, and there is a transition payment for some Housing Benefit claimants moving across. Official guidance on that payment is reassuring on one point:

The wider point is that these benefits still exist as gateways to other help even as they close. Funeral Support Payment in Scotland, for example, still lists Universal Credit, Income Support, Pension Credit, Housing Benefit, income-based JSA and income-related ESA among its qualifying benefits³¹. And Income Support itself cannot be paid abroad, except for a temporary absence under special circumstances, a rule worth knowing if you are planning time outside the UK³².

Where Universal Credit differs from legacy benefits

Universal Credit is means-tested and replaces and combines six legacy benefits and tax credits for working-age households on a low income³³. The design differences from the old system are not cosmetic. Payment is monthly (twice a month in Northern Ireland and by arrangement elsewhere) rather than the mixed fortnightly and weekly cycles of the old benefits²¹. Assessment is monthly and continuous, so changes in earnings change the payment each month rather than triggering a new claim¹⁶.

The fiscal effect of the redesign has been examined by the Office for Budget Responsibility. It estimated £10.9 billion of gross savings in 2022-23, where Universal Credit is less generous than the benefits it replaced and is expected to result in lower costs from error and fraud, but the actual effect of Universal Credit relative to the legacy system was estimated to be £1.0 billion rather than the £2.4 billion difference in entitlements, once behavioural responses are taken into account³⁴. For an individual claimant, the practical differences that matter most are the monthly assessment, the wider duty to report changes, and the fact that help with rent now usually sits inside the single payment rather than arriving separately from the council.

Tax credits overpayments and letters after the move

Letters about tax credits do not stop the day the benefit ends. When you moved to Universal Credit, HM Revenue and Customs will have sent you a letter called "Your Tax Credits over-payments" (TC1131)²⁵. That letter sets out any overpayment from your tax credits claim, money that still has to be repaid even though the benefit itself has closed.

Repayment usually continues through the new system. Universal Credit will write to you saying how much you owe, and you can repay online¹⁶. You may still be paying back benefit overpayments even if your Universal Credit claim ends¹⁶. If you move from Universal Credit to another benefit, repayments will usually continue from your benefit payments until the advance is paid off²⁷.

Separately, Universal Credit claims are reviewed from time to time. A review might find that you are being paid too much Universal Credit, that you are entitled to more, or that there is no change to your amount³⁵. If a review finds an overpayment, the same repayment routes apply. If you disagree with a decision, you can ask for it to be looked at again, and the page on challenging a decision explains the process.

Where to get free help

The move is a process with deadlines, and free help exists at every stage. If you get a Migration Notice and are unsure what to do, the deadline on the letter is the thing to act on first, and the page on what to do if you get a Migration Notice walks through the steps. If money is tight while waiting for the first payment, the advances and budgeting loans page sets out what can be borrowed and how repayment works.

For a check on whether you will be better or worse off, free calculators and advisers let you compare your current position with an estimated Universal Credit award before you commit. In Northern Ireland, nidirect carries the official guidance on the move and on grants and advances³. If a decision about your claim goes against you, mandatory reconsideration and redetermination is the first formal step, and complaining to the DWP covers where a complaint can go.
