Next month, those receiving the State Pension are likely to find out that their weekly payments will increase by 4% from April 2020.

This means the full new State Pension will see an increase from £168.60 per week to £175.35 and the full old basic State Pension will see a rise from £129.20 to £134.35.
 
Under current rules, the State Pension is increased by the ‘triple lock’ which is the highest of earnings growth, price inflation or 2.5% a year.

The price inflation figure used is for the year to September, which will be announced in mid-October, following a fall in the August figure to 1.7%, down from 2.1% the previous month.

But the earnings growth figure used is that to July (seasonally adjusted and including bonuses), which was 4%.

This means pensioners are on track to receive a 4% increase, far above the rate of increases currently being seen with prices.

The triple lock was announced back in 2010 as a way of making sure pensioners did not lag behind the working age population in terms of their State Pension purchasing power.

It was first used to increase State Pensions in April 2011 and since then, state pensioners have done well from the triple lock with overall increases outstripping both price inflation and earnings growth.
 
A single person receiving the old basic State Pension which was £97.65 back in April 2010 is now receiving £129.20, an increase of 32% while prices have increased by 24% and average earnings by only 20%.

Relevant factors for uprating of State Pension under the ‘triple lock’
 
Steven Cameron, pensions director at Aegon, said: “Based on the latest earnings growth figures, it looks like state pensioners can look forward to an inflation busting 4% increase in their state pension from next April.

“Under a special arrangement called the ‘triple lock’, the current Government has committed until 2022 to increase state pensions each April by the highest of earnings growth, price inflation or 2.5%.

“The price inflation figure used is that for September, and won’t be announced until later in October, but the latest figure for August was down at 1.7%.

“The earnings growth figure used is that for the year to July, and has already been announced at 4%.

“So subject to any last minute adjustments, pensioners look like they’ll see a 4% increase from next April.
 
“Those who reached state pension age on or after 6 April 2016 will be receiving the single state pension and if entitled to the full amount, a 4% increase would see their state pension go from £168.60 to £175.35 per week.

“For those who reached state pension before then and are entitled to the full basic state pension, a 4% increase on their current £129.20 per week would mean £134.35 from next April.
 
“This will be welcome news for current state pensioners.

“However, these inflation busting increases do come at a significant cost.

“The state pension is not funded in advance so pensions are funded on a ‘pay as you go’ basis from today’s workers’ National Insurance contributions.

“With the prospect of an early General Election, it will be interesting to see where each party stands on commitments to retaining the triple lock for the next five years.”
