How to check your State Pension forecast

Go to the Check your State Pension forecast service on GOV.UK and sign in. You will need a GOV.UK One Login or an older Government Gateway account, and you will have to confirm your identity — usually with a passport, a UK driving licence, or details from a recent payslip or P60. If you cannot get through the identity check online, the forecast can be requested by post or by phone instead.

The forecast gives you three things. The first is the amount you have built up to date, expressed as a weekly figure. The second is the amount you could get if you carry on contributing until State Pension age. The third is your State Pension age itself, which is not fixed for life — it has been legislated upwards more than once, and the date shown is the date under the law as it currently stands.

The gap between the two amounts is the important part. If the forecast says you have built up less than the full amount but could reach it by continuing to work, the honest answer for most people in their forties and fifties is to do nothing at all: ordinary employment will fill the remaining years automatically. If it says you cannot reach the full amount even by working to pension age, that is the signal to look at the record in detail.

Underneath the forecast sits your National Insurance record, year by year, since you were 16. Each year shows as a full year, a year with a shortfall, or a year with nothing. A year is full when you paid or were credited with enough contributions across the whole tax year — not when you worked for part of it. Someone who worked eight months of a tax year on decent pay may still have a full year; someone who worked all year on very low weekly earnings across several small jobs may not.

Look for three specific patterns. Years abroad appear as gaps and usually are gaps, though a reciprocal social security agreement may mean the foreign contributions count towards qualifying, and periods in the EU, Switzerland, Norway, Iceland or Liechtenstein are handled under separate coordination rules. Years of self-employment appear as shortfalls where Class 2 was not paid or was not collected properly — a known problem for people whose Self Assessment returns did not carry the Class 2 charge through. Years of low-paid or part-time employment appear as shortfalls where earnings sat below the qualifying threshold.

The forecast also flags a Contracted Out Pension Equivalent, usually shown as COPE, if you were ever in a contracted-out scheme. This is the single most misread part of the whole service, and it deserves its own explanation.

Print or save the forecast. If you later ring the Future Pension Centre or HMRC, the first thing they will ask about is what your record shows, and having the year-by-year list in front of you turns a long call into a short one.

Before April 2016 the State Pension had two parts: a flat basic pension and an earnings-related additional pension, at various times called SERPS or the State Second Pension. Employers running a salary-related occupational scheme could contract their employees out of the additional pension. In exchange, both the employer and the employee paid a lower rate of National Insurance, and the workplace scheme promised to provide at least an equivalent benefit.

Almost every public sector scheme — NHS, teachers, civil service, local government, police, fire, armed forces — was contracted out, along with a very large number of private final salary schemes. If you worked in any of those before April 2016, you were almost certainly contracted out for part of your career whether or not you remember being told.

When the new State Pension started in April 2016, everyone with a pre-2016 record was given a starting amount: the higher of what they had built up under the old rules and what they would have built up if the new rules had always applied. The contracted-out deduction is applied in working out that starting amount. The result is that people with long contracted-out service often show a starting amount well below the full new State Pension, even with a complete contribution record.

This is not a mistake and it is not a loss in the round. The reduced National Insurance you paid at the time went into a workplace scheme that should be paying you a corresponding benefit. But it does mean two things in practice. First, the number of qualifying years you need to reach the full new State Pension can be more than the headline figure. Second, additional post-2016 qualifying years can increase your amount up to the full rate, so continuing to work or to be credited genuinely adds money for people in this position.

The practical instruction is simple: do not count your years and assume you know the answer. Read the forecast. It has already done the calculation, including the contracted-out adjustment, on your actual record.

If your forecast shows you at the full amount already, further qualifying years add nothing to the State Pension. That is worth knowing before you consider paying voluntary contributions, and it is the most common reason a voluntary payment turns out to have been wasted.

National Insurance credits fill gaps for free, and a large number of people who are entitled to them never claim. Credits are awarded automatically in some situations and only on application in others, and the ones that need an application are exactly the ones that get missed.

Child Benefit is the big one. A parent or carer claiming Child Benefit for a child under 12 receives credits that protect their State Pension record. The trap is the High Income Child Benefit Charge: where one partner's income is high, families often decide not to claim at all. That decision also throws away the credits. The correct move is to register the claim and elect not to receive the payments — you get the credits, and no charge arises because no money is paid. This has cost a great many parents, overwhelmingly mothers, whole qualifying years.

Carer's Credit is available to people caring for someone for at least a set number of hours a week who are not entitled to Carer's Allowance. It is claimed on a form, not awarded automatically, and it is one of the least-claimed credits in the system.

Specified Adult Childcare Credits transfer the credit attached to Child Benefit from a parent who does not need it — typically because they are working and building their own record — to a grandparent or other family member under State Pension age who provides childcare. Both parties have to agree and the claim is made retrospectively after the tax year ends.

Credits are also awarded while claiming Carer's Allowance, Universal Credit, Jobseeker's Allowance, Employment and Support Allowance, Maternity Allowance, statutory maternity, paternity or adoption pay in some circumstances, and for people on jury service or receiving certain disability benefits. Class 3 credits also cover spouses and civil partners of members of the armed forces accompanying them on posting abroad.

Two practical points. Credits generally have to be applied for within time limits, so an old gap may no longer be fixable by credit even though it was fixable at the time. And a credit and a voluntary contribution do the same job for the same year — so always check whether a credit is available before paying, because the credit is free.

Voluntary contributions let you pay for a past year that is incomplete. Class 3 is the general route; Class 2 is the cheaper self-employed route where you qualify for it. The ordinary rule is that you can go back six tax years, though extended windows have been opened at various times for people affected by the 2016 transition, and the deadline for those has moved more than once. Check the current position on GOV.UK rather than relying on a date you read somewhere.

Work through it in this order. First, look at the forecast: if you are already at, or will reach, the full new State Pension through ordinary work, stop — paying adds nothing. Second, check whether the gap year can be filled by a credit instead. Third, if a payment does look worthwhile, ring the Future Pension Centre if you are below State Pension age, or the Pension Service if you have reached it, and ask them to confirm which specific years will increase your pension and by how much.

That phone call is not a formality. There are several situations where paying does nothing at all: your starting amount is already the maximum; the year falls in a period where a contracted-out deduction absorbs the benefit; or you have enough post-2016 years already scheduled to reach the full rate. HMRC will accept the money in all of those cases. It will not tell you it was pointless, and it will not refund it as a matter of course.

Where a payment does work, the arithmetic is usually striking. A single qualifying year adds a fixed increment to the weekly pension for life. For anyone with normal life expectancy, the payment is typically recovered within a small number of years of drawing the pension, after which it is pure gain — and it is index-linked. Very few financial products offer that. This is why the advice is to check whether it works, not to avoid it.

Get a reference number from HMRC before paying. Voluntary contributions paid without the correct reference are a well-known source of payments landing unallocated, and chasing them afterwards is slow. Keep the payment confirmation and check the National Insurance record a few weeks later to confirm the year has flipped to full.

Finally, consider order of operations against other uses of the same money. Paying off expensive debt, or capturing an employer pension match you are currently declining, will usually beat a voluntary contribution. Voluntary National Insurance is excellent value where it works, but it is not the first call on limited money.

The State Pension is not paid automatically. You have to claim it, and the invitation letter usually arrives a few months before State Pension age. If you do nothing, the pension is simply deferred rather than lost.

Deferring increases the amount you eventually receive. Under the new State Pension the increase accrues for each full period of deferral and is paid as a higher weekly pension for life; under the older rules a lump sum option existed for some people. The increase is worthwhile for people who expect to live a long time and who do not need the income now, and poor value for people in poor health or who need the money immediately.

Deferring interacts badly with means-tested benefits. If you are receiving Pension Credit, Housing Benefit or certain other income-related help, deferring generally does not increase those payments and can leave you worse off overall. Anyone in that position should claim rather than defer.

Working past State Pension age does not stop you receiving the pension, and you stop paying employee National Insurance on your earnings from that point — though the employer continues to pay theirs. Your pension income is taxable, but it is paid without tax deducted, so the tax is usually collected by adjusting the code on another source of income, which is a frequent cause of surprising tax codes in the first year of retirement.

Check whether Pension Credit is available. It tops up income for people over State Pension age on low incomes, and it is significantly under-claimed. It also acts as a passport to other help — including help with council tax, NHS costs and, in some years, cost of living or heating payments — so the value of claiming is usually well above the top-up itself.

Get proof of your State Pension when you need it for a mortgage, a tenancy, a visa or a benefit claim. GOV.UK provides a downloadable statement rather than requiring a letter to be posted, which is faster than most people expect.

The State Pension and National Insurance are reserved matters. The rules, the qualifying years, the forecast service and the voluntary contribution regime are identical in England, Scotland, Wales and Northern Ireland, and the same GOV.UK service covers all four nations.

Northern Ireland runs its own delivery. Social security in Northern Ireland is a transferred matter operated in parity with Great Britain, and pensions and National Insurance there are administered by the Department for Communities rather than the Department for Work and Pensions. In practice the entitlement is the same, but the contact points and much of the published guidance are on nidirect rather than GOV.UK, and using the Northern Ireland pages avoids being given a Great Britain phone number that cannot help you.

What genuinely differs is everything wrapped around the pension. Scotland has devolved a substantial part of the benefits system to Social Security Scotland, so a Scottish pensioner's non-pension support — including winter heating assistance and carer benefits — comes from different schemes with different names and different rules from the equivalents in England and Wales. Council Tax Reduction, help with health costs and social care charging also diverge across the four nations.

Pension Credit itself is a reserved benefit and works the same way UK-wide, but the passported help it unlocks does not. A Pension Credit award opens different doors in Glasgow, Cardiff, Belfast and Bristol, so check the devolved guidance for what a successful claim entitles you to locally.

The practical rule: use GOV.UK for the pension itself wherever you live, use nidirect if you are in Northern Ireland and need to contact someone, and use mygov.scot, GOV.WALES or nidirect for the surrounding benefits and services, which are where the four nations actually part company.

National Insurance records do contain errors, and the two most common are worth knowing. The first is missing Home Responsibilities Protection or its successor credits for years spent caring for children — an error that affected a large cohort of people, overwhelmingly women, whose Child Benefit claims did not carry a National Insurance number. The second is unpaid or unallocated Class 2 contributions for self-employed years, where the charge was not collected correctly through Self Assessment.

Both are correctable, and correcting them is free. Contact HMRC's National Insurance enquiries line with the years in question and the evidence you have — Child Benefit correspondence, payslips, P60s, employer names and dates, or Self Assessment records. Missing employed earnings can often be reconstructed from the employer's own returns.

If HMRC's record disagrees with your evidence and you cannot resolve it, there is a formal route: ask for the decision to be reviewed, and if that fails, appeal to the First-tier Tribunal. This is the same appeal structure used for tax decisions, and there is no fee to appeal a National Insurance decision.

Where the problem is not the record but the way you were dealt with — long delays, wrong information given on the phone, a payment lost — use HMRC's complaints process first, then the Adjudicator's Office, and then the Parliamentary and Health Service Ombudsman through your MP. Redress for direct financial loss caused by official error is available, but only if you complain in a form that creates a record.

Keep evidence permanently. Old P60s, payslips and Child Benefit letters are the only practical way to reconstruct a record from decades ago, and the people who successfully fix forty-year-old gaps are almost always the ones who kept the paper.

Finally, re-check after any correction. A fixed year should appear as a full year on the National Insurance record and should move the forecast. If it does not move the forecast, that is itself useful information — it usually means the year was never going to add anything, which is the same reason not to have paid for it.
