UK State Pension guide: how much you'll get and how to boost it

The new State Pension (for people reaching State Pension age from 6 April 2016 onwards) is based on your National Insurance (NI) record. You need 35 qualifying years of NI contributions to get the full amount. A qualifying year means you've either been working and paying NI, receiving NI credits (for example, if you're claiming certain benefits, caring for a child under 12, or registered as unemployed), or made voluntary NI contributions. The minimum qualifying period is 10 years — below that, you get nothing. Between 10 and 35 years, you get a proportional amount.

The State Pension age is 66 for both men and women, and it is rising to 67 between 2026 and 2028, and to 68 between 2044 and 2046 (though this timeline may be brought forward). You can check your personal State Pension age on the government website. You can defer claiming your State Pension — for every 9 weeks you defer, your pension increases by 1%, which works out to roughly 5.8% extra per year. Whether deferral is worthwhile depends on your health, other income, and tax situation.

The single most important thing you can do is check your State Pension forecast on the GOV.UK website (search 'Check your State Pension forecast'). You'll need a Government Gateway or GOV.UK One Login account. Your forecast shows: how much State Pension you're currently on track to receive, how many qualifying years you have, any gaps in your NI record, and what you can do to improve your pension amount. Check this at least every few years — it takes 5 minutes and could be worth thousands in retirement.

If your forecast shows gaps (years where you didn't pay enough NI), you may be able to fill them by making voluntary NI contributions (Class 3). In 2026/27, Class 3 contributions cost £18.40 a week, so a full missing year costs about £957 to fill, and could add approximately £358 per year to your State Pension. That means you'd recoup the cost in under 3 years of pension payments, and then benefit for the rest of your life. You can usually go back 6 years to fill gaps; the special window that allowed you to fill gaps back to 2006 closed on 5 April 2025. Check whether filling gaps would actually increase your pension — in some cases it won't, and the government forecast tool will tell you.

You may be entitled to NI credits that you're not receiving. Parents and guardians claiming Child Benefit automatically get NI credits for years when their child is under 12. If the Child Benefit is claimed by your partner but you're the one not working, you can have the credits transferred. Carers providing 20+ hours/week for someone on certain benefits get Carer's Credit. People on Jobseeker's Allowance, Employment and Support Allowance, or Universal Credit usually get NI credits automatically. If you think you're missing credits, contact HMRC to investigate.

The State Pension counts as taxable income, but it's paid gross (without tax deducted). If your total income (State Pension plus any other income) exceeds the Personal Allowance (£12,570), you'll pay income tax on the excess. Since the full new State Pension (about £12,548 a year in 2026/27) is just below the Personal Allowance, you can receive it tax-free if it's your only income. But any additional income — workplace pension, savings interest, part-time work — could push you into tax territory. Plan for this so you're not surprised by a tax bill in retirement.

The State Pension increases each year by the highest of: average earnings growth, inflation (CPI), or 2.5%. This 'triple lock' means the State Pension's purchasing power is protected over time — it should always at least keep pace with the cost of living. The triple lock has been politically controversial (it's expensive for the government), and there are periodic debates about replacing it with a 'double lock'. For now, it remains in place, which means the State Pension should continue growing in real terms.

The State Pension is free money from the government that you've earned through your working life — make sure you get every penny you're entitled to. Check your forecast online, fill any gaps that are cost-effective to fill, and make sure you're getting all the NI credits available to you. Combined with a workplace pension and personal savings, the State Pension forms a crucial part of a comfortable retirement. The earlier you check and act, the more you can do to maximise it.
