What is the triple lock pension and how does it affect me?

The state pension triple lock

The ‘triple lock’ is a safeguard that currently applies to the UK state pension, to ensure that it doesn’t lose value because of inflation. Here’s how the triple lock pension works, and what it means for you and your retirement income.

The triple-locked state pension

A triple lock was introduced to the UK state pension in 2010. It was a guarantee that the state pension would not lose value in real terms, and that it would increase at least in line with inflation. To make the guarantee even more secure, it included three separate measures of inflation (hence ‘triple lock’).

The three-way guarantee was that each year, the state pension would increase by the greatest of the following three measures:

  • Average earnings
  • Prices, as measured by the Consumer Prices Index (CPI)
  • 2.5 per cent

In other words, if average earnings were to increase by 3 per cent, the state pension would also increase by 3 per cent. But neither average earnings nor the CPI increase by more than 2.5 per cent, the state pension still rises by 2.5 per cent.

Thus if wage growth and price growth remain low, the state pension increases actually beat inflation – as has happened a lot in the years since the triple lock was put in place.

What does the triple lock mean for me?

If you are currently receiving the state pension, the triple lock ensures that your spending power will not diminish over the course of your retirement (for as long as all three guarantees remain in place). It also means that if inflation is below 2.5 per cent, your pension increases will actually beat inflation – thus improving your spending power.

Why is the triple lock good for pensioners?

It’s clearly important for pensioners that the state pension increases over time. Retirement can be a period of 25 year or even more, and over such a length of time prices can increase dramatically. For example, 25 years ago a litre of petrol cost only around 50 pence. This is particularly important given the relatively low size of the UK state pension (only £9,110.40 a year in 2020/21).

Will the triple lock be taken away?

The state pension triple lock has proved to be a burden for successive governments, as it has proved costly for the taxpayer. On several occasions the government has considered modifying the triple lock, for example to replace it with a double lock based only on increases in earnings or CPI (whichever is the higher). However, voters have so far proved to be against the idea.

As of 2020, however, the present government has a sizeable majority and the next election is years away. It is therefore conceivable that the state pension triple lock may again come under scrutiny (as the government may not get a better chance to remove it).

What would happen to my state pension without the triple lock?

The loss of the triple lock would not have a huge immediate impact on pensioners, especially if it were replaced with a double lock. The level of the state pension would still rise with inflation – it just wouldn’t exceed it.

A more pessimistic scenario would be for the state pension to have only a single lock, linked either to earnings or the CPI but not both. In this case, pensioners’ spending power might deteriorate over the medium to long term.

The worst-case scenario would be the complete loss of any lock, and a return to the times when increases in the state pension were simply made at the whim of the Chancellor in the annual Budget. This is unlikely, but can’t be ruled out altogether.

What can I do to safeguard my retirement income?

If you are not yet drawing your state pension and are still working, it is a good idea to save as much into workplace or personal pensions as possible. Given that the state pension is far from generous in any case, and that the state pension age continue to rise, it is sensible not to rely too much on it in any case. The state pension should be seen as a supplement to private pension savings – not the other way round.
