Bank of England authors assess the UK’s productivity slowdown and AI prospects
Markdown · JSON · Original source
On August 27, 2026, Bank of England authors Sophie Piton and Fabrizio Cadamagnani assess UK productivity trends against historical and international comparisons. They argue that productivity growth slowed across G7 economies, but the slowdown was particularly large in the UK, in part because manufacturing’s share declined more than in peer countries and because of Brexit. The authors report that revisions to UK data have reduced the measured productivity slowdown, while a planned change to the measurement of hours worked may lead to further upward revisions. They also caution that recent supply shocks and measurement issues complicate comparisons since the pandemic. Looking ahead, the authors say the UK’s tech sector contributes more to productivity growth than other European economies, and that AI adoption could lift UK productivity. They present this as a possibility, not an established outcome: the timing and size of AI’s effects remain uncertain. The article also notes that the reasons for weak UK performance are not settled and that evidence on some proposed explanations is mixed. How much, and when, might AI adoption change UK productivity growth?

Open question
How much, and when, might AI adoption change UK productivity growth?
Source-stated
The authors report that productivity growth weakened across G7 economies, with a particularly large slowdown in the UK.
Productivity growth has been weak across G7 economies over the past two decades
Source-stated
The authors identify the UK’s greater decline in manufacturing’s share and Brexit as factors behind its larger slowdown.
The slowdown was particularly large in the UK, mainly because it experienced a larger decline in the share of manufacturing than peers and then because of the impact of Brexit.
Source-stated
The authors say revisions to UK data reduced the measured productivity slowdown, and a change to how hours worked are measured may lead to further upward revisions.
The publication of the ONS Bluebook 2021, which introduced important revisions to historical data, and most importantly ‘double deflation’, significantly reduced the measured UK productivity slowdown since the GFC
Source-stated
The authors say the UK’s tech sector contributes more to productivity growth than tech sectors in other European economies, and that AI could lift UK productivity, though the effect is uncertain.
There are reasons to think AI adoption may materially and persistently lift UK productivity growth, although the timing and magnitude of AI impacts are highly uncertain.
Source-stated
The authors report that the reasons for the UK’s poor productivity performance remain disputed.
There is a large academic literature on the reasons for poor UK performance and still no consensus.

attribution — pass: The reading correctly credits Sophie Piton and Fabrizio Cadamagnani, who work at the Bank of England, and attributes the arguments to them rather than to the Bank institutionally. The source notes the views are the authors' own.
Sophie Piton and Fabrizio Cadamagnani work in the Bank’s Structural Economics Division.
summary — pass: The summary clearly states the actors, the argument (a G7-wide slowdown that was larger in the UK, attributed to manufacturing decline and Brexit), the measurement caveats, and the conditional AI outlook. It is understandable without specialist background. The question follows from the source's stated uncertainty about AI's timing and size. Saying 'in part' where the source says 'mainly' softens the wording but does not misrepresent it.
This offers some optimism for the future of UK productivity, although there is still a lot of uncertainty on the nature and timing of the change that AI is going to bring.
date — pass: originalPublished is 2026-08-27, which matches the page dateline of 27/08/2026. The reading uses no later events and no hindsight framing. AI effects are presented as possibilities, not outcomes. The evidence kind is publisher-page, so no archive-copy disclosure is required. The page was edited after publication, and the limitations disclose this. The cited passages are core article text.

support — pass: Each claim matches a verbatim passage in the article body: the G7-wide slowdown, the manufacturing and Brexit drivers, data revisions, the larger UK tech contribution relative to other European economies, the conditional AI uplift, and the lack of consensus on causes. The page was edited after publication, but the cited passages are central body text that is plainly part of the piece. No unsupported benefits or costs are implied.
The contribution of IT and other information services to total economy annual labour productivity growth is larger in the UK than in other European economies
media — pass: No media was selected, and no verified media candidates were supplied, so choosing none is appropriate.
