What is the triple lock on a State Pension?

This content was reviewed and approved by our in-house advisory panel.

The triple lock guarantee was introduced in 2011 as a safeguard to provide peace of mind to the nation’s pensioners. But it’s come at a substantial cost to the British taxpayer, especially when other pensioner benefits are factored in. That means it’s under constant scrutiny by politicians – and the future of the pension triple lock rules is often the subject of much debate.

Read on to learn exactly how the triple lock on the State Pension works, why it might change in the years ahead, and what you can do today to protect your retirement finances.

What is the UK State Pension?

The UK State Pension provides additional financial support during your retirement. If you qualify, you’ll receive a weekly payment from the government to top up your retirement income from a workplace or private pension scheme.

The State Pension is worth up to £230.25 a week for most retirees and is usually paid out every four weeks. You can start claiming the UK State Pension from the age of 66 for both men and women. This is set to increase to 67 between 2026 and 2028, and to 68 between 2044 and 2046.

The exact age you can claim depends on your date of birth. To find the earliest you can claim, check your State Pension age on GOV.UK.

The amount of State Pension you’ll receive depends on your National Insurance record. You usually need at least 35 years of contributions or credits to qualify for the full State Pension, and at least 10 years to get anything.

The State Pension is typically used to supplement your private pension savings.

What is the triple lock on The State Pension?

Each UK State Pension hike is based on a system known as the triple lock. It takes place in April every year and ensures the annual increase in State Pension payments matches or even beats the official rate of inflation. It guarantees this by taking three separate measures into account.

Thanks to the triple lock, the State Pension should rise each year by whichever of the following three percentages is highest: 

• Inflation: How much general living costs have risen according to the previous September’s Consumer Prices Index (CPI) report.
• Average earnings growth: The average wage increases from May to July of the previous year.
• A rate of 2.5%.

Following changes in 2016, there are now three types of State Pension:

• The new State Pension.
• The basic State Pension.
• The additional State Pension (which is only paid in addition to the basic State Pension).

What you receive depends on when you’re due to reach the official State Pension age. Only the new State Pension and basic State Pension are covered by the triple lock guarantee. 

How much rise in State Pension does the triple lock bring? 

Following a brief suspension during the COVID pandemic, the UK Treasury reinstated the State Pension triple lock from April 2023. This meant a rise of over 10.1% to help keep pace with the cost of living in the 2022/2023 financial year. The Basic State Pension and new State Pension were also increased by 8.5% in April 2024 in line with earnings growth.

In 2024, the CPI rate was 1.7% and the average wage increase was 4.1% Therefore, the full new State Pension increased by 4.1% in April 2025 to:

• £230.25 per week for individuals.
• £460.50 per week for married couples combined.

There are no longer any special State Pension arrangements for married couples. Each individual in a marriage or civil partnership must build up their own State Pension pot.

The full basic State Pension also increased by 4.1% in April 2025 to £176.45 for individuals.

You don’t have to do anything to benefit from the UK State Pension triple lock. Any increase in your payments is automatically calculated and applied for you in April every year.

You may also be entitled to an annual pension increase if you live abroad. This depends on where you live, and you can check if you qualify via the GOV.UK website.

What’s excluded from the triple lock on pensions?

Most UK State Pensions are protected by the triple lock guarantee. However, there are two exceptions that increase in line with the CPI rate instead. These are:

• Additional State Pension: This is part of the old State Pension scheme that you might receive if you reached pension age before 6 April 2016.
• Any extra money you receive if you deferred your State Pension to a later date.

What do the triple lock pension rules mean for me?

Inflation can pose a major financial headache once you reach retirement. The cost of living could rise significantly during your retirement years, gradually eroding the value of your pension income in real terms.

To prevent this from happening to UK pensioners, the triple lock guarantees the State Pension will increase by at least 2.5% every year. It also means the State Pension hike has risen at a faster rate than if it had tracked one element alone, such as inflation.

With the triple lock in place, it ensures your State Pension payments hold their value against inflation each year. As an added bonus, the triple lock can even mean your State Pension rises faster than inflation, if the official CPI reading is below 2.5%.

On the downside, there is constant speculation about how and when the triple lock might be reformed in the future. Every Chancellor faces calls to make it less generous ahead of every Budget announcement, creating uncertainty for anyone receiving the State Pension or nearing retirement.

What is the future of the triple lock guarantee?

There are currently no plans to end the State Pension triple lock in the UK. However, with the cost of the State Pension already running into many billions of pounds, political commentators and think-tanks have cast doubt on the long-term sustainability of the triple lock.

Given the State Pension increased by 10.1% in 2023, 8.5% in 2024, and 4.1% in 2025, some experts have called for a ‘double lock’ to be introduced in its place – with payments only rising by either the CPI inflation rate or average wage growth. 

The fairness of the current triple lock on the State Pension has also faced heavy scrutiny, potentially sparking tensions between different generations. Pressure may start to mount on the Government if State Pension increases significantly outpace workers’ wage rises.

What will happen if the triple lock guarantee is removed?

Future generations will likely bear the brunt of any changes to the triple lock pension guarantee. In particular, those planning to leave work in the next five to 10 years might have to quickly recalculate their expected pension income and target retirement age. 

Whilst the triple lock on the State Pension was reinstated for the 2023/24 tax year, it is under constant review and the topic of much debate amongst politicians. There’s currently no firm indication that ministers plan to amend or scrap the triple lock on the State Pension. But if you’re concerned about your future retirement income, you should speak to a financial adviser to discuss your options.

Protecting your pension income

Whether you’re just starting out in your career or approaching retirement, it’s vital to keep an eye out for any official announcements regarding the triple lock. 

You can also safeguard your retirement finances by reducing your reliance on the State Pension in the first place. If you view it more as a top-up for your workplace or personal pension savings, you’ll be shielded from any major rule changes that come into force between now and your retirement. From defined contribution and defined benefit schemes to self-invested personal pensions, there are plenty of options out there.
