How three numbers decide next year's pension

Every autumn, three numbers are laid side by side. One of them decides what the full State Pension rates will be from the following April. The other two are set aside until the next year, when the same comparison happens again.

That comparison is what people mean by the Triple Lock. It is not a formula that produces a number of its own, and it is not a promise about anybody's individual payment. It is a rule about which of three published measures gets used.

Knowing how it works explains two things that otherwise look strange: why the increase is announced in the autumn but paid from April, and why the headline percentage does not apply evenly to every line on a pension award.

The three measures, and where each one comes from

The three candidates are not invented for the purpose. Each is an existing published statistic or a fixed figure.

Growth in average earnings. This comes from the Office for National Statistics' average weekly earnings series, which tracks total pay across the economy. The reading used for the pension comparison is taken from a set period over the summer and published in the autumn.

Consumer price inflation. This is the Consumer Prices Index figure for September, also published by the ONS. September is used because it gives enough lead time for the Department for Work and Pensions to set rates, lay them before Parliament and get them into payment systems before April.

A flat 2.5%. The third measure is simply a floor. It exists so that the full rates still rise in a year when both earnings and prices are flat or falling.

Term explained: the determining measure

The one of the three measures that turns out to be highest in a given year, and therefore sets the increase. It changes from year to year, which is why no single percentage describes the Triple Lock.

What the 2026 comparison looked like

For the April 2026 uprating, the earnings measure was the highest of the three. The table below sets the three candidates against each other as published figures.

Published figures for the 2026/27 uprating. Source: DWP benefit and pension rates 2026 to 2027.

So the full new State Pension rate rose by 4.8%, from £230.25 to £241.30 a week, and the full basic State Pension rate rose by the same percentage, from £176.45 to £184.90. Those are standard full rates, not amounts confirmed as due to any particular person.

The 3.8% that is easy to miss

Here is where the Triple Lock gets misread. It governs the full basic and new State Pension rates. It does not govern every component that can appear on a State Pension award.

Additional and protected elements — the earnings-related parts built up under the pre-2016 rules — are uprated by the September price inflation figure instead. For 2026/27, that was 3.8%, not 4.8%.

The practical effect is that somebody with a basic pension plus an additional element has two different percentages running through one award. Multiplying the whole thing by 4.8% overstates the increase. We set that out in more detail in the part of a pension that rises by a different number.

Why the gap between announcement and payment

The September inflation reading is published in October. The earnings figure arrives around the same point in the autumn. The Secretary of State then conducts the annual review of rates, the figures are set out in an uprating order, and that order goes before Parliament.

Payment systems, pension letters and the thousands of other benefit rates tied to the same annual review all need those confirmed figures. By the time the new rates reach bank accounts, in the first weeks of the new tax year, the numbers behind them are already six months old.

This is also why an announcement in the autumn and an increase in the spring are the same event described twice. Nothing new happens in April beyond the rate taking effect.

Why one percentage does not describe your own payment

A percentage applied to a full standard rate produces a change in that full standard rate. It does not produce a change in an individual payment unless the individual happens to be on exactly that rate with no other components.

Three things commonly break the link:

• A partial entitlement. A new State Pension below the full rate rises by the same percentage, but from a lower base, so the cash difference is smaller.
• Mixed components. A basic pension with an additional element has parts moving at 4.8% and parts moving at 3.8%.
• Where the pension is paid. Annual upratings are not paid in every country, so an overseas recipient may see no change at all. See why some pensions abroad never go up.

A worked example, for illustration only

Take two hypothetical recipients, both under the older system, both affected by the same April uprating.

Illustration only. A made-up additional element is used to show how two percentages behave inside one award. Real awards vary, and this is not a calculation of anybody's entitlement. The combined rise here works out at roughly 4.6% — close to the headline, but not equal to it.

What the Triple Lock does not promise

It is a method for choosing an uprating measure. It is not a guarantee that a pension will keep pace with any particular household's costs, and it says nothing about tax. Because the tax-free Personal Allowance has been held at the same level for several years while pension rates have risen, the gross increase and the change in income after tax are not the same thing. That is the subject of the allowance that stays still while pensions rise.

What to take from it

If you want to know what the Triple Lock did this year, look up which of the three measures was highest. If you want to know what it did to your pension, that is a different question, and the answer is on your own award paperwork rather than in the national figure. The three lines worth checking on your pension letter are the quickest route to it.
