State Pension Triple Lock: How It Works, Pay Rates, and Coverage

The state pension triple lock is the UK government’s commitment to raise the basic and new state pensions each April by whichever is highest of three measures: Consumer Prices Index inflation, average earnings growth, or a minimum of 2.5%. For April 2026, earnings growth won at 4.8%, taking the full new state pension to £241.30 a week and the full basic state pension to £184.90 a week.¹²

The Three Measures and How the Winner Is Picked

Each autumn the government looks at three numbers and picks the largest to set the following April’s increase:

CPI inflation for September, which tracks price changes across a basket of everyday goods and services.
Average weekly earnings growth across the UK for the May-to-July period.
A 2.5% floor that applies when both inflation and wage growth come in below that level.

The underlying statutory duty comes from Section 150 of the Social Security Administration Act 1992, which requires the Secretary of State to review benefit rates every tax year.³ That law only requires uprating in line with earnings or prices. The triple lock adds the 2.5% floor and the “highest of three” rule as a policy pledge on top. Because it is a pledge rather than a statutory formula, a future government could change it without repealing an Act of Parliament.⁴

What the Full State Pension Pays in 2026/27

September 2025 CPI came in at 3.8%, average earnings for May to July 2025 rose 4.8%, and the floor was 2.5%. Earnings won, so pensions rise 4.8% from April 2026.⁵ The new weekly rates are:

Full new state pension: £241.30 per week, or £12,547.60 per year, for anyone who reached state pension age on or after 6 April 2016.¹
Full basic state pension: £184.90 per week, or £9,614.80 per year, for anyone who reached state pension age before 6 April 2016.²
Pension Credit standard minimum guarantee: £238.00 per week for a single person, £363.25 for a couple.²

Which Pensions the Lock Actually Covers

Only two parts of the state pension get the triple lock: the basic state pension and the new state pension. Both get the full benefit of whichever measure is highest each year.⁴

Other payments follow different rules. The Additional State Pension, sometimes called SERPS or the Second State Pension, rises only with CPI.⁶ Pension Credit has its own uprating rules under separate legislation. For 2026/27 Pension Credit rose by 4.8%, but that happened to match the triple lock figure rather than being governed by it. In a year when the numbers diverge, only the flat-rate state pension is guaranteed the highest of the three.

Qualifying Years You Need for the Full Amount

Getting the full new state pension of £241.30 a week requires 35 qualifying years of National Insurance contributions. You need at least 10 qualifying years to receive any new state pension at all. Below that threshold, you get nothing.⁷

A qualifying year is one in which you paid NI through employment, received NI credits (for example while claiming certain benefits or caring for a child under 12), or paid voluntary contributions. If your NI record started before April 2016 and you were contracted out of the Additional State Pension at any point, you may need more than 35 years, because a deduction applies for the period you were contracted out.¹ Before April 2016 many employees were contracted out through a workplace or personal pension, either paying NI at a lower rate or diverting some contributions into a private scheme. This catches people off guard when they check their forecast and find the full amount is not on the table.⁸

Gaps in your record can sometimes be filled with voluntary Class 3 contributions. It is not always worth doing. If you were contracted out, voluntary payments might not increase your pension at all. Check your forecast or contact the Future Pension Centre before paying anything to confirm that extra contributions will actually boost your entitlement.⁹ Deadlines apply to buying back specific tax years, so the longer you wait, the fewer gaps you can fill.

When the Annual Rise Reaches Your Bank Account

The Office for National Statistics publishes the September CPI figure in October, and the May-to-July earnings data appears around the same time. The Secretary of State for Work and Pensions confirms the increase in an autumn statement, and the new rates take effect at the start of the tax year in April.

The government sends notification letters to all recipients before the change, confirming the new weekly or four-weekly payment amount. If your pension is paid on a four-weekly cycle, your first payment at the new rate reflects whichever payment date falls after the April start.

Tax Is Catching Up With the Pension

The state pension counts as taxable income, but it is paid without any tax deducted. That is about to matter for a lot more people. The personal allowance, the amount you can earn before income tax kicks in, has been frozen at £12,570 since April 2021 and stays frozen until at least April 2028.¹⁰

The full new state pension now pays £12,547.60 a year. That is £22.40 below the personal allowance. Any other income at all, whether a small private pension, part-time work, savings interest, or rental income, will push you past the threshold and into paying 20% tax on the excess. If the triple lock delivers another healthy increase within a year or two, the state pension alone will exceed the personal allowance, and every pensioner receiving the full amount will owe some tax even with no other income.

When you owe tax on your state pension and have no employer running PAYE, HMRC sends a Simple Assessment letter showing your taxable income and the amount due.¹¹ If you also receive a private pension, HMRC usually adjusts the tax code on that pension to collect what is owed on both. Either way the bill lands with you; the state pension itself arrives untaxed and settling up is your responsibility.

Living Abroad: When Increases Stop

If you retire overseas, whether you keep getting the triple lock increases depends on where you live. Your pension continues to rise each year if you live in the European Economic Area, Gibraltar, Switzerland, or a country with a social security agreement with the UK. Canada and New Zealand are the notable exceptions: they have agreements with the UK, but pensions are still frozen there.¹²

Frozen means your pension stays at whatever rate it was when you left the UK, or when you first became entitled if you were already abroad. Someone who moved to Australia or Canada a decade ago could be receiving hundreds of pounds a year less than someone in the UK with an identical contribution record. Move back to the UK and your pension jumps to the current rate, but you do not get back pay for the frozen years.¹²

The One Year It Was Suspended

The triple lock has been applied every year since 2011/12 with one exception. In 2021 average earnings growth hit 8.3%, later revised to 8.4%, as the economy rebounded from pandemic-era furlough. The government called the figure a statistical distortion rather than genuine pay growth, and Parliament passed the Social Security (Uprating of Benefits) Act 2021 to suspend the earnings element for one year. Pensions rose by 3.1% in April 2022, tracking CPI instead.⁴

The episode showed that the triple lock is a political commitment, not an unbreakable legal guarantee. Overriding it required a specific Act of Parliament, which shows the pledge carries weight, but a government with the votes and the fiscal argument can set it aside.

Checking Your Own Forecast

You can check your projected state pension amount, your qualifying years to date, and any gaps in your NI record through the GOV.UK state pension forecast tool. The service shows whether paying to fill gaps would actually raise your pension. You will need to verify your identity, typically with a passport or driving licence.¹³ The forecast is not available if you are already receiving your state pension or have deferred claiming it. You can also reach it through the HMRC app.

Checking early matters. If you find a gap with years still left before your state pension age, voluntary contributions are relatively cheap compared with the lifetime income they can add. Discover the gap at 65 and your options narrow, with the deadline for paying possibly already gone.
