The Office for National Statistics has revised its productivity estimates, putting average UK growth at 1.3% a year from 2009 to 2019, rather than 0.7%. The revision reflects a lower estimate of hours worked, not higher economic output, and changes how Britain compares with other G7 economies.
The Office for National Statistics (ONS) has revised its estimate of UK productivity growth in the decade after the global financial crisis, putting average annual growth at 1.3% from 2009 to 2019, up from a previous estimate of 0.7%. The change reflects a revised estimate of how many hours people worked, not an increase in measured economic output, and makes Britain look less like an outlier among the G7 economies.
Productivity is commonly measured as economic output per hour worked. According to MoneyWeek’s account of the revised ONS figures, the agency now estimates that this measure increased at an average rate of 1.3% each year between 2009 and 2019. Earlier estimates put the annual average at 0.7% over the same period.
The revision does not mean the UK produced more goods and services than previously recorded. Rather, the ONS has revised down its estimate of the hours worked in the period. When the same output is divided by fewer estimated hours, the resulting output-per-hour figure is higher. The change is therefore to the measured productivity rate, not to the level of output described in the report.
MoneyWeek says the revised figures place the UK in the top half of the G7 for productivity, instead of among the group’s weaker performers. The source material does not provide the country-by-country data or the comparison period behind that ranking, so the position should be understood as the report’s description of the new comparison, rather than a full account of each economy’s results.
How the Revision Changes Britain’s Ranking
The revision alters the account of a long-running UK economic weakness. If productivity growth in the decade after the financial crisis was stronger than earlier estimates suggested, then the scale of the slowdown may have been overstated. It also changes how the UK’s performance is presented against other large advanced economies: MoneyWeek says the new estimate puts Britain in the G7’s top half, rather than leaving it an apparent outlier.
That matters because productivity is a measure of how much output an economy generates for each hour worked. It is relevant to understanding economic performance over time, but the revised growth rate does not by itself show that workers’ output, household incomes, or living standards are higher than previously believed. The source account says the output level was not revised upward; the difference comes from the estimated hours in the calculation.
The figures may also affect how analysts interpret the UK’s performance during this period. A revised statistical series can change comparisons and assessments without any underlying change to the economy itself. Readers should distinguish that accounting change from evidence of a sudden improvement in current productivity or a resolution of the broader economic challenges associated with weak output growth.

The Post-Crisis Productivity Puzzle
The period covered by the revision is 2009–19, the decade following the global financial crisis and ending before the COVID-19 pandemic. The UK’s productivity record over the post-crisis years has often been described as unusually weak. MoneyWeek’s report says the new ONS estimate changes that picture by more than doubling the estimated average annual growth rate for the decade, from 0.7% to 1.3%.
The measure at issue is output per hour, not output per worker or total economic output. Its calculation depends on estimates of both production and hours worked. A revision to either part can alter the productivity result, which is why updated statistics may change the historical account even where the output figure itself is unchanged.
The report does not say that every year in the decade saw growth of 1.3%; that is the average annual rate it attributes to the revised figures. Nor does the supplied material describe the ONS’s methods, the size of the hours-worked revision, or how the agency’s estimates compare with other statistical measures.
“The rate of growth in the decade following the global financial crisis, from 2009–2019, was 1.3% each year, on average, rather than the 0.7% they had previously thought.”

Details Behind the Revised Hours Estimate
The material provided does not specify when the ONS issued the revision, what data or methodological changes prompted it, or exactly how much the estimated hours worked changed. It also gives no detailed G7 table, so the precise margins between the UK and other member economies cannot be checked from this account alone.
It is also unclear from the source material whether the revised rate applies uniformly across the decade or how individual years changed. The 1.3% figure is presented as an average for 2009–19. It should not be treated as a description of productivity growth after 2019, or as a forecast of future performance.

Further ONS Data Needed
The next step for readers seeking a fuller picture is to consult the ONS’s revised productivity and hours-worked series, including its explanation of the changes and the annual figures behind the decade average. Those details would help clarify how the new estimate was constructed and how it affects comparisons with other G7 economies.
Until that supporting information is considered, the confirmed development in the source material is a historical statistical revision: estimated productivity growth for 2009–19 is higher because estimated hours worked are lower. It does not establish that current UK productivity has improved or settle how the country will perform in future.

Key Questions
What productivity figure has changed?
The ONS estimate of average annual UK productivity growth for 2009–19 has been revised from 0.7% to 1.3%, according to MoneyWeek’s report.
Did the UK produce more than previously recorded?
No. The report says the revision does not raise the measured level of economic output. It results from a lower estimate of the hours worked.
Why does a lower estimate of hours raise productivity?
Productivity in this measure is output divided by hours worked. If the output figure stays the same while estimated hours fall, output per hour rises.
Does this show that Britain’s current productivity problem is over?
No. The revision covers the historical period 2009–19. The supplied report does not provide evidence about current productivity growth or future performance.
How does the revised estimate affect the UK’s G7 position?
MoneyWeek says the revision puts Britain in the top half of the G7 rather than making it an apparent outlier. The supplied material does not include the detailed country comparisons or ranking data.
