What’s changed: Updated 21 October 2026: September’s CPI came in at 3.5%, below earnings growth of 3.9%, so earnings set the April 2027 rise. Earlier, 12 October: a DWP factsheet gives the third part of the 2030 rule in official wording. Full update history.

On 29 September the Prime Minister, Andy Burnham, told the Labour conference that the State Pension triple lock will stay exactly as it is until 2030, and then change. By the evening the headlines had it as the end of the triple lock, and some coverage was calling the replacement a “double lock”.
Neither label fits what was said. The rule announced for 2030 still has three parts, and the State Pension would still rise every year by at least inflation or 2.5%. What goes is one feature of the current rule, and that feature is where most of the cost has come from.
What the Prime Minister said about the triple lock
The speech text published by the Labour Party has two sentences on it. The first covers this Parliament:
We promised in our manifesto to keep the Triple Lock unchanged throughout this Parliament. I will honour that promise.
The second covers what happens after it:
From there, in April 2030, we will adjust it. The state pension will continue to rise every year at least by prices or 2.5%. And it will hold its value relative to earnings over time so that pensioners will always share in the rising prosperity of the nation.
The savings, he said, will go towards a new National Care Service, to be introduced in the next Parliament and “fully funded, and not through borrowing.”
The triple lock is unchanged until April 2030
The triple lock raises the basic and new State Pension each year by the highest of three things: growth in average earnings, CPI inflation, or 2.5%. That rule applies to the April 2027, 2028 and 2029 increases just as it does now.
The next of those is close to settled. Average earnings grew 3.9% in the year to May to July 2026, which would take the full new State Pension from £241.30 to about £250.70 a week from April 2027. September’s CPI figure, published by the Office for National Statistics on 21 October, was 3.5%, so earnings are the highest of the three measures and set the rise. The government usually confirms the figure around the Budget. Our piece on the State Pension and the personal allowance covers what the April 2027 figure means for tax.
How the triple lock would work from 2030
The Department for Work and Pensions described the new rule in an analysis published the same day. The State Pension is to keep the “record high value relative to earnings” it reaches over the next three years, and each year it rises by at least inflation or 2.5%, plus “anything more that is needed to retain that value”. The Institute for Fiscal Studies set the same rule out as the highest of:
- CPI inflation;
- 2.5%;
- the increase needed for the State Pension to keep up with average earnings growth since the new policy started.
On 6 October the DWP added a factsheet that puts the third part in the department’s own words. From April 2030 the State Pension rises each year by the highest of inflation, 2.5%, or “the amount required to return or maintain the value of the State Pension relative to earnings”. The factsheet also says people already receiving a State Pension “will continue to receive their Triple Lock pension until April 2030”, and come under the adjusted rule from then.
Inflation and the 2.5% floor carry on as they are. The earnings leg is what changes. At the moment it looks at one year at a time: if earnings rose 4% over the year, the pension rises 4%. From 2030 it would look at the whole period since the new rule began, and add only what is needed for the pension to catch up with earnings over that period.
The ratchet, and why the new rule removes it
The difference shows after a bad year for wages. Under the current rule, a year of slow earnings growth still gives pensioners 2.5% or inflation, whichever is higher. When earnings recover the following year, the pension rises by the full earnings figure on top of that higher base, and the extra is never given back. Each weak year leaves the State Pension permanently a little further ahead of earnings. The IFS calls this the “ratchet”.
Under the new rule the weak year is treated the same way, but the recovery year is not. Because the pension is already ahead of where earnings have got to, it rises only by enough to draw level with them, subject to the inflation and 2.5% floors. A simple illustration, with inflation at 2% throughout and a pension starting at 100:
| Year | Earnings rise | Earnings index | Current rule | New rule |
|---|---|---|---|---|
| 1 | 1% | 101.0 | 102.5 | 102.5 |
| 2 | 4% | 105.0 | 106.6 | 105.1 |
| 3 | 4% | 109.2 | 110.9 | 109.2 |
The IFS put a number on the ratchet by looking backwards: “if the new policy had been in place since 2011, state pension expenditure this year would be £9 billion lower than it is today, more than halving the £16 billion annual cost in 2026-27 of having retained the unreformed triple lock for the last 15 years.”
Why “double lock” is the wrong label
A double lock would rise by inflation or 2.5% and nothing else, and over a long period that would let the State Pension fall behind wages, which is the opposite of what the Prime Minister said. The earnings link stays. It moves from a year-by-year test to a test over the whole period since 2030, so the pension keeps pace with average earnings over the long run instead of pulling steadily ahead of them. The years that would look different are the ones straight after a weak year for wages, when the rise would be smaller than under the current rule.
The IFS calculated that if the new rule had applied from 2010 to 2026, the State Pension would still have risen by 6% more than inflation over the period. It rises in real terms under both rules, more slowly under the new one.
Three savings figures, measuring three different things
£15 billion a year by the end of the 2030s. The government’s figure for what the change will save. The DWP analysis puts the saving at £15 billion in 2039 to 2040 and £50 billion in 2049 to 2050 in cash terms, or £11 billion and £30 billion in 2025 to 2026 prices. The figures come from the department’s long-run model. It calls them illustrative and says they should not be used to work out the saving in any single year. The IFS’s Jonathan Cribb said on 30 September that the saving is “very uncertain” and “could reasonably be anywhere between £4 billion and £20 billion”. For 2034 to 2035 the IFS expects about £4 billion a year, “but it could easily save nothing at all if earnings growth is strong.”
£9 billion. The IFS’s look-back: what spending would be this year if the new rule had been in place since 2011, which makes it a measure of the past rather than a forecast. On the future, the IFS said savings “are likely to be relatively small in the first few years, but rise substantially over time,” and added: “We should not expect this reform to save enough that it could fund universal social care in the next parliament.”
£16 billion. The IFS’s estimate of what the current triple lock is costing in 2026-27, compared with a State Pension that had simply risen with earnings since 2011.
Some coverage has also quoted an Office for Budget Responsibility figure. It comes from an earlier OBR scenario rather than the policy announced on 29 September, so it is left out here.
Is the triple lock written into law?
Only part of it. Section 150A of the Social Security Administration Act 1992 requires the Secretary of State to review the State Pension every year and, if earnings have risen, to increase it “by a percentage not less than the percentage by which the general level of earnings is greater.” That is the legal duty, and it covers earnings alone. The inflation leg and the 2.5% floor are a government commitment on top of it, which is why a Prime Minister can announce a change to them in a speech. For the 2030 change, Downing Street’s announcement says: “The Government will legislate for the change during this Parliament.”
Public service pensions are not affected
If you have an NHS, teachers’, Civil Service, local government, armed forces, police or firefighters’ pension, that pension has never used the triple lock. Public service pensions in payment rise each April in line with CPI for the year to the previous September, under the Pensions Increase legislation. This year shows the two rules side by side: in April 2026 the State Pension rose 4.8%, led by earnings, while public service pensions rose 3.8%, the September 2025 CPI figure. Nothing announced on 29 September changes the public service rule. The State Pension you draw alongside a scheme pension is the part the new rule would reach.
What is not decided yet
The formal rule. The DWP analysis and the factsheet that followed it describe the rule in words, not as a formula, and the analysis says its projections “are not forecasts of future government policy”. The detail will be settled in the legislation the government has promised for this Parliament.
The timing against the election. The change is timed for April 2030. The next general election has to be held by August 2029, so the rule would take effect under whichever government is elected then.
The care service it pays for. The National Care Service is promised for the next Parliament. Its design is with a review led by Louise Casey, and there is no costing yet to set against the savings.
What to watch
- 21 October: September CPI, which fixes the April 2027 increase under the current triple lock.
- 28 October: the Budget, the first chance for the Treasury to publish the rule and its own costing.
- Any DWP or Treasury paper setting out the formula itself, which would settle the questions above.
If you are thinking about topping up your National Insurance record, the value of each extra year depends partly on how the pension rises after you retire. The age at which you can claim is a separate question from the amount, and our State Pension age 68 explainer covers that side.

Update history: 21 October 2026
Update, 21 October 2026: The Office for National Statistics published September’s CPI figure on 21 October: 3.5%. That is below earnings growth of 3.9%, so earnings set the April 2027 State Pension rise, taking the full new State Pension to about £250.70 a week, subject to the government confirming it. The paragraph on the April 2027 rise now says so.
Update, 12 October 2026: On 6 October the Department for Work and Pensions added a factsheet to its analysis of the change. It gives the third part of the rule from April 2030 as “the amount required to return or maintain the value of the State Pension relative to earnings”, and says people already receiving a State Pension keep the current triple lock until April 2030. Both points are now quoted in the section on how the rule would work from 2030, the paragraph on the formal rule mentions the factsheet, and it has been added to Sources. Nothing else in the article has changed.
