UK State Pension Triple Lock: Measures, Timing, and 2026/27 Rates

The UK State Pension triple lock is the government’s pledge to raise the basic and new State Pension each April by whichever is highest of three figures: Consumer Price Index inflation, average earnings growth, or 2.5%. For the 2026/27 tax year, earnings growth of 4.8% was the winning measure, lifting the full new State Pension to £241.30 per week and the full basic State Pension to £184.90 per week.1GOV.UK.

The Three Measures and Which One Wins

Every autumn, the Department for Work and Pensions puts three numbers side by side and picks the largest. That number becomes the percentage increase for the following April.

The first is CPI inflation, which tracks how much everyday goods and services have risen in price over the year. The second is average earnings growth across the economy, which keeps retirees in step with working households rather than falling behind during pay rises. The third is a fixed 2.5% floor, which guarantees a minimum uplift even when both prices and wages are flat.

In most years the deciding figure has been either inflation or earnings. The 2.5% floor rarely wins, but it exists for stagnant years when the other two measures dip below it.2House of Commons Library. State Pension Triple Lock

How and When the Figures Are Measured

The triple lock uses fixed data windows rather than live economic readings, which keeps the process predictable.

CPI is taken from the 12-month change recorded in September, as published by the Office for National Statistics. Whatever happens to prices in the months afterwards does not feed into that year’s calculation. The earnings figure comes from average weekly earnings including bonuses, measured over the three-month period from May to July. That three-month window smooths out short-term pay fluctuations. The 2.5% floor needs no measurement at all; it simply sits in the comparison as a fixed number.

Because the inputs are locked in by late summer, the April rise is essentially set long before pensioners see it.

From Autumn Announcement to April Payment

The Chancellor normally confirms the chosen percentage at the Autumn Budget. The Secretary of State for Work and Pensions then lays a draft Social Security Benefits Up-rating Order before Parliament, which both Houses must approve. That order is the legal instrument that turns the policy pledge into binding payment rates.3legislation.gov.uk. The Social Security Benefits Up-rating Order 2026

The new rates take effect on 6 April, the start of the tax year. Retirees see the higher amount in the first payment cycle after that date. The gap between the autumn announcement and the April switchover gives DWP several months to update payment systems for more than 12 million pensioners.1GOV.UK.

What Rises By the Full Amount, and What Doesn’t

Not every part of a State Pension payment goes up by the headline triple lock figure. The full increase applies to the basic State Pension and the new State Pension. Other components follow a different, usually lower, rule.

If you reached State Pension age before 6 April 2016, you may receive additional amounts on top of your basic pension. The most common is the additional State Pension, previously known as SERPS, along with the older Graduated Retirement Benefit. Those components rise by CPI only, not by the triple lock.2House of Commons Library. State Pension Triple Lock

The same CPI-only rule applies to a “protected payment” under the new State Pension. This is the portion of your entitlement that sits above the full flat rate because you built up additional pension rights before 2016. Extra amounts earned by deferring a State Pension claim are also uprated by CPI alone.

In a year like 2026/27, where the triple lock delivered 4.8% but CPI was lower, someone with a large additional State Pension will see a smaller overall percentage rise than the headline suggests. The basic or new State Pension slice gets the full 4.8%; everything else gets CPI.

2026/27 Payment Rates

The 4.8% uplift produced the following full weekly rates:

The full new State Pension works out to roughly £12,548 a year. The income tax personal allowance stays frozen at £12,570 for 2026/27, which leaves a gap of just £22.5GOV.UK. Income Tax Rates and Allowances for Current and Previous Tax Years The State Pension alone does not quite trigger a tax bill, but any extra income from a workplace pension, savings interest, or part-time work is taxed from the first pound above the allowance. With the allowance frozen and the triple lock still pushing pension payments up each year, that remaining gap will probably close within a year or two.

When the Triple Lock Was Suspended

The triple lock has applied every year since 2011/12 with one exception. For 2022/23, the government passed the Social Security (Uprating of Benefits) Act 2021 to remove the earnings component from the calculation for a single year.2House of Commons Library. State Pension Triple Lock

The reason was the pandemic. As furloughed workers returned to full pay, average weekly earnings jumped by 8.3% (later revised to 8.4%). The government argued the figure was an artefact of the recovery rather than real wage growth, and that applying it would hand pensioners a windfall disconnected from economic conditions. With earnings taken out, pensions rose by 3.1% that year, the September 2021 CPI figure. The full triple lock was restored the following year.

Is the Triple Lock Guaranteed by Law?

No. The triple lock is a government policy pledge, not a statutory rule. The legal minimum is lower: the Secretary of State must review State Pension rates each year and uprate the basic and new State Pension at least in line with earnings.6legislation.gov.uk. Social Security Administration Act 1992 – Section 1502House of Commons Library. State Pension Triple Lock

The triple lock sits above that floor by adding CPI into the comparison and guaranteeing a minimum 2.5% rise in flat years. Because it is a commitment rather than a law, a government can set it aside without repealing anything, as happened in 2022/23. The political cost of doing so tends to be high given how many voters it affects, but the commitment has already been broken once in its short history.

If You Live Outside the UK

The triple lock does not follow every retiree overseas. Your State Pension is only uprated each year if you live in the European Economic Area, Gibraltar, Switzerland, or a country with a reciprocal social security agreement with the UK. Canada and New Zealand are specific exceptions where pensions are frozen despite existing agreements.7GOV.UK. State Pension if You Retire Abroad – Rates of State Pension

If you live in a country without a qualifying agreement, which includes much of the Commonwealth, your pension is frozen at the rate it was when you left the UK or first claimed abroad. The frozen rate does not rise with inflation, earnings, or the 2.5% floor. If you later return to the UK, your pension is restored to the current rate.
