That’s a favourably timed spike for the calculation of next year’s state pension, which takes the September CPI reading as one of the inputs of the triple lock.
 

“It’s possible that wage growth may trump inflation, and pensioners get an even bigger bump in their income. But if the Bank of England is right about inflation, then pensioners can look forward to a rise of at least 4% in their state pension next year.

“No doubt this will once again raise questions about the fairness of the triple lock, especially against a fiscal backdrop which suggests the chancellor is going to have to stick a shovel into taxpayers’ pockets again in the autumn Budget.”

Eamonn Donaghy, spokesperson for campaigners Later Life Ambitions said, “Politicians and policy researchers need to keep their hands off the triple lock.

“It is all that stands between many pensioners and a level of poverty that nobody deserves or ought to have to live with, especially after most have worked and contributed throughout their lives.

“It’s a policy that has been a great success since it’s introduction in ensuring some of the UK’s most vulnerable people can live with dignity.

“Even if these predictions come true, we are only talking about an increase of about £9 per week and our state pension will still remain among the most stingy in Europe.

“And we all know that the cost of basic essentials like food and energy regularly outstrip the headline inflation rate.”

The IMF has warned that the triple lock “could be replaced with a policy of indexing the state pension to the cost of living” to help the Chancellor avoid breaking her pledge not to increase taxes on “working people”.

Think tank the Institute for Fiscal Studies last month said that pensions should increase in line with average earnings, and said the triple lock “increases the value of the state pension in an unpredictable way”.
