The Triple Lock: What It Is and Why It Matters for UK Expats

The triple lock is one of the most consequential policy decisions in the history of the UK State Pension. Introduced in 2010, it has delivered cumulative pension increases well in excess of general price inflation, and it has significantly raised the real value of the State Pension for those who benefit from it. But for the hundreds of thousands of UK expats living in frozen countries, the triple lock might as well not exist — they receive none of its benefits, and the gap between their static frozen pension and the uprated pension received by those in the UK grows wider every year.

Understanding the triple lock, who benefits from it, and how to plan around its absence (or potential future removal) is essential for any UK national with overseas retirement plans.

What Is the Triple Lock?

The triple lock is the policy of increasing the State Pension each April by whichever of the following three measures is highest:

1. CPI inflation — the Consumer Prices Index measure of price inflation, usually measured in the twelve months to September of the previous year
2. Average earnings growth — the growth in average UK wages, usually measured in the three months to July of the previous year
3. 2.5% — a guaranteed minimum floor, ensuring the pension always grows by at least 2.5% even in low-inflation, low-wage-growth environments

The policy was introduced by the Conservative–Liberal Democrat coalition government in 2010 as a way of protecting pensioners' purchasing power and rebuilding the real value of the State Pension, which had fallen significantly in the 1980s and 1990s when it was linked only to prices.

What the Triple Lock Has Delivered

In the first decade of the triple lock's operation, the 2.5% floor was frequently the highest of the three measures, delivering consistent if modest increases. More recently, with the surge in inflation and wage growth following the pandemic, the triple lock delivered much larger increases:

• 2023/24: 10.1% — the CPI measure triggered, reflecting the energy and cost-of-living crisis (raising the full new State Pension to £203.85 per week)
• 2024/25: 8.5% — earnings growth was the highest measure, raising the full new State Pension to £221.20 per week
• 2025/26: 4.1% — earnings growth again, raising the full new State Pension to £230.25 per week
• 2026/27: 4.8% — earnings growth, raising the full new State Pension to £241.30 per week (£12,548 per year) from April 2026

To illustrate the cumulative effect: a pensioner receiving £130/week in the 2014/15 tax year, had they benefited from full uprating through to 2025/26, would now be receiving a pension approaching £200/week — and often exceeding that figure depending on the precise starting point. The triple lock has added many thousands of pounds to the cumulative pension income of those living in uprated countries.

Why the Triple Lock Makes Zero Difference for Frozen Country Residents

This is the critical point for expats in countries without a bilateral social security agreement with the UK. If you retire to Australia, Canada, Thailand, the UAE, Egypt, Indonesia (including Bali), India, Pakistan, South Africa, or any of the other frozen countries, your pension is fixed at the rate it was when you first claimed it — or when you first moved to that country, if you had already claimed. It does not increase by CPI, by earnings, or by 2.5%. It does not increase at all.

A UK pensioner who moved to Australia in 2015 receiving £130/week then still receives £130/week now — while an equivalent pensioner who remained in the UK or moved to Spain would be receiving somewhere above £200/week. The shortfall, compounded across a retirement, represents a very large sum.

For clients in frozen countries, the triple lock is effectively irrelevant to their own income. What it does affect is the contrast between their frozen pension and the pensions of friends and family in the UK, which grows more stark with every uprating. It also affects the importance of planning supplementary income that provides some form of inflation protection.

The Political History and Current Position

The triple lock has been a contentious policy throughout its existence. Critics argue that the 2.5% minimum floor is indefensible in low-growth environments, and that pensioner households are better protected than working-age households. The Office for Budget Responsibility and various think tanks have modelled the long-term cost of the triple lock, which rises with pension age demographics.

Significant events in the triple lock's political history include:

• 2011–2019: The Conservative government maintained the full triple lock through multiple parliaments
• 2022/23: The triple lock was temporarily suspended for one year, with earnings growth excluded because the post-furlough recovery produced a statistically distorted earnings figure. The government did not want to apply a mechanistic 8%+ increase based on an artificial earnings bounce. The pension rose by CPI (3.1%) instead
• 2023/24 and 2024/25: The full triple lock returned and delivered its largest-ever awards (10.1% then 8.5%)
• 2024: The Labour government, elected in July 2024, pledged to maintain the triple lock for the current parliament
• 2025/26: The 4.1% earnings-linked increase was applied, raising the full new State Pension to £230.25 per week
• 2026/27: The 4.8% earnings-linked increase raised the full new State Pension to £241.30 per week (£12,548 per year), maintaining the full triple lock commitment

As of 2026, the triple lock is in place and the Labour government has not signalled an intention to remove it during this parliament. However, longer-term — particularly as State Pension costs rise with an ageing population — the future of the triple lock beyond this parliamentary term is genuinely uncertain. The 2.5% floor is probably the most politically vulnerable element; a shift to a "double lock" (higher of earnings or CPI) is frequently discussed in policy circles.

The Impact of Potential Triple Lock Changes

For those in uprated countries, any weakening of the triple lock would reduce the rate at which the State Pension grows. The 2.5% floor has been particularly valuable in years of low inflation and stagnant wages — without it, pensions would have grown more slowly in the 2010s. However, in the recent high-inflation environment, the 2.5% floor has been irrelevant, with CPI and earnings both comfortably exceeding it.

For those in frozen countries, changes to the triple lock make no difference to their own pension, as they receive no uprating regardless.

Planning Implications for Expats in Frozen Countries

The combination of a frozen pension and the triple lock's benefits accruing elsewhere makes it essential for clients moving to frozen countries to build retirement income plans that do not rely on the State Pension growing in real terms.

In a frozen country, your State Pension's purchasing power will erode with local inflation over time. If Thai inflation runs at 2–3% per year and your pension is fixed in sterling, the real purchasing power of your pension in baht falls each year, compounded by both local inflation and any sterling depreciation.

Our planning approach for clients in frozen countries typically involves:

• Maximising the State Pension starting rate before freezing (filling NI gaps, considering deferral to lock in a higher frozen amount — see /uk-pensions/guides/state-pension-deferral-and-planning-overseas)
• Building private pension or investment income that can grow over time
• Ensuring some income streams are linked to local currency or inflation
• Not over-relying on the State Pension as a percentage of total retirement income

Sterling vs Local Currency: The Currency Dimension

For those in frozen countries, a practical consideration is whether to receive the State Pension in sterling (into a UK bank account) or convert it to local currency. In an environment where sterling is stable or strengthening, keeping the pension in sterling and converting at advantageous moments can help preserve purchasing power. In a prolonged sterling depreciation environment, the opposite applies.

We generally advise clients not to view currency management as a substitute for inadequate retirement income — but thoughtful currency planning can meaningfully reduce the cost of living off a frozen sterling pension.

Our Perspective on Relying on State Pension as Sole Income Abroad

In our experience, clients who have the State Pension as their primary or sole retirement income source face genuine financial risk, particularly in frozen countries. The State Pension of £241.30/week (£12,548/year in 2026/27) is a meaningful income floor in the UK, where it benefits from the NHS, Winter Fuel Payment (historically), and other state provisions. Abroad — particularly in higher-cost expat environments — it is unlikely to be sufficient on its own.

We are frank with our clients about this. The State Pension should be seen as a foundation, not a plan. The triple lock makes it a more valuable foundation for those in uprated countries. For frozen country residents, building the rest of the retirement income picture is not optional.

Pension rules, rates, and political commitments around the triple lock are subject to change. This guide reflects the position as of 2026.

How Global Investments Can Help

For clients in uprated countries, we help model the future value of the State Pension — including reasonable triple lock assumptions — as part of a comprehensive retirement income plan. For clients in frozen countries, we focus on the planning required to compensate for the absence of uprating: building an investment and income portfolio that grows in real terms even as the State Pension does not.

Our team also monitors the political landscape around the triple lock and NI contribution rules, alerting clients when changes could affect their plans. Whether you are five years from retirement or already drawing the State Pension, we can help you understand exactly what it contributes to your income picture and what else needs to be in place alongside it.
