Those who reach the state pension age, which is currently 66, and have 35 years of National Insurance contributions under their belt, are usually entitled to get the full payment.

Claimants of the state pension are guaranteed to see their payment rates rise every year thanks to the triple lock.

This is a pledge to raise payments every year by either the rate of inflation, average earnings or by 2.5 per cent; whichever is higher.

Andrew Oxlade, the executive head of Personal Finance at Fidelity International, warned that future Governments will have a “difficult balance to strike” when managing “additional costs” of the state pension going forward.

The finance expert cited life expectancy and demographic trends as being contributing factors, outside of the triple lock.

He explained: “While longer lifespans are something to celebrate, they come with additional state costs.

“The ‘triple lock’ must also be considered. State pension payments have grown at a decent clip over the past decade, even though it was downgraded to a ‘double lock’ during the recent inflation spike.

“The third consideration in cost is the demographic bulge in the number of people reaching retirement age – the so-called baby boomers – coupled with historically low fertility rates.
