The UK’s most significant business story on Monday, 24 August 2026, was the Resolution Foundation’s claim that Britain has been experiencing a hidden productivity boom, with output per hour rising far faster since late 2024 than official data suggests.

That finding matters because productivity is the central measure of long-term economic health: if the think tank is right, the UK economy may be emerging more strongly from the post-financial-crisis malaise than policymakers and markets have assumed.

UK productivity growth may be stronger than the official numbers show

Britain’s economy may have undergone a two-year “silent productivity boom,” according to new research from the Resolution Foundation, which argued that UK productivity has been growing at about 1.1% a year since late 2024, well ahead of the Office for National Statistics’ current estimate of 0.2%.

The think tank’s assessment suggests official statistics may be understating the economy’s underlying momentum, potentially altering the debate around wages, inflation, tax revenues and the government’s fiscal room for manoeuvre.

Productivity has been one of the UK’s weakest economic fault lines since the 2008 financial crisis, with sluggish output growth helping to hold down living standards and complicate efforts to raise wages without reigniting inflation. A material upward revision would be politically significant as well as economically important.

Why the finding matters for business and investors

For companies, stronger productivity growth would imply that firms are producing more with the same or similar labour input, a development that can support profit margins, wage growth and investment confidence. For investors, it would also change how Britain’s growth prospects are interpreted after years of concern about structural weakness.

The timing is notable because other recent market and economic indicators have pointed to a mixed backdrop: business activity has shown signs of improvement, but employment growth has remained soft, while policymakers continue to balance growth concerns against inflation risks.

What happens next

The key question now is whether the Resolution Foundation’s analysis proves durable or whether it will be revised as official data catch up. If the think tank is right, the UK could be in the early stages of a more meaningful productivity recovery than many forecasters have been willing to credit.

That would not erase the country’s longer-term growth problems, but it would suggest that Britain’s economy may be in a better position than the headline data have implied — a development likely to influence Westminster, the Bank of England and the business community alike.
