Britain is on the cusp of the worst sickness crisis on record following a post-lockdown surge in worklessness that is driving a “rapid rise” in benefit claims.
Analysis by the Resolution Foundation showed the share of working-age people who are economically inactive owing to long-term sickness had climbed “consistently” over the past four-and-a-half years from two million in the summer of 2019 to 2.7 million today.
This is the second-longest sustained rise in sickness-related inactivity on record and just one month shy of the record set in the 1990s.
The think tank described the sharp rise in the number of people who are neither in work nor looking for a job as the “legacy of the pandemic”.
Louise Murphy, senior economist at the Resolution Foundation, said Britons were getting older and sicker, which did not bode well for reversing the trend.
She added: “We can’t be sure of what the future will hold. But we definitely don’t see any indication that this is starting to turn a corner and go down.
“So all that it would take is another couple of months of increases and things will be looking even worse than in the 1990s.”
The UK is still the only G7 economy where employment is yet to recover to pre-lockdown rates, and a total of 9.25 million people of working age are now classed as economically inactive.
The Resolution Foundation noted that 90pc of the increase in overall economic inactivity had been driven by younger adults aged between 16 and 24 and older adults aged between 50 and 64 since the start of the pandemic.
It said the rise in ill-health had a “knock-on impact” on welfare claims.
“There has also been a rapid rise in the number of working-age adults claiming sickness and disability-related benefits,” the Foundation said, adding that people in their early 20s are now more likely than those in their 30s or early 40s to be claiming benefits related to a health condition or disability.
Official projections by the Office for Budget Responsibility (OBR) published this week show spending on health and disability benefits is expected to rise by more than a third over the next five years from £65.7bn in 2023-24 to £90.9bn in 2028-29.
The Foundation said the most “striking” increase in benefit claims related to personal independence payments (PIP), which is now the main non-means-tested benefit for those with health conditions or disabilities. The benefit can be claimed by people both in and out of work, though OBR analysis suggests just 16pc of those who claim PIP are in work.
New PIP claims have increased 68pc between early 2020 and early 2024, according to the Foundation. Adults aged between 55 and 64 are the most likely group to be claiming PIP, with the most common conditions including osteoarthritis and anxiety.
