Experts said the wage growth measure under the triple lock pensions guarantee is likely to be used to calculate next year's rise.

People on the new full state pension are set for a rise of over £500 a year from next April following the latest official earnings data.

Under the triple lock guarantee, the state pension increases every April in line with whichever is the highest of total earnings growth in the year from May to July of the previous year, CPI (Consumer Prices Index) inflation in September of the previous year, or 2.5%.

The latest figures from the Office for National Statistics (ONS) showed a rise in total wage growth including bonuses to 4.7% in the quarter to July, up from 4.6% in the three months to June.

While the final piece of the puzzle will not come until inflation figures for September are published in October, it is thought unlikely that the rate of Consumer Prices Index will be higher than 4.7%.

Inflation currently stands at 3.8%, with the latest data for August due out on Wednesday.

Experts said this means the wage rise will be used to calculate the figure for the annual increase, putting pensioners on track for a 4.7% uplift in the state pension next year.

However, the wage growth figures are subject to revision when next month's jobs market data are released.

Hargreaves Lansdown said that based on a rise of 4.7%, this would see a full new state pension increase from its current level of £230.25 per week to £241.05 per week from April.

Those retiring on the basic state pension would see their weekly income increase from £176.45 per week to £184.75.

Helen Morrissey, head of retirement analysis at Hargreaves Lansdown, warned the increase in the state pension would put many pensioners close to the threshold for paying income tax.

She said: "If they receive the 4.7% uplift it takes their annual state pension to around £12,535 per year which leaves them just a whisker under the threshold of paying basic rate tax."

She added: "The increase will also add further pressure on the Government who are battling an already burgeoning state pension bill.

"The Government has committed to keeping the triple lock in place for the rest of this Parliament but longer term its future could be uncertain.

"With a review into state pension age also ongoing, other options could include an extension of the current timetable with dates for state pension age running into the late 60s and beyond."
