ONS's accompanying economic commentary identifies services as the main contributor, particularly professional, scientific and technical activities, and information and communication. It also reports real GDP 1.4% above its year-earlier level. The annual comparison answers a different question from the 0.5% increase over the preceding quarter. ONS: Quarterly economic commentary, April–June 2026 The revisions policy explains that the national accounts form an integrated system: changed information in one area can affect other series. Revisions may incorporate fuller source data or routine recalculations. A revision is therefore an update to the measured history, and should be assessed separately from a new quarter's first observation. ONS: National Accounts Revisions Policy, updated January 2026 WFN analysis: the higher estimate gives sterling research a firmer historical growth baseline. It cannot, on its own, establish stronger present demand or a change in the Bank of England's intentions. An assessment of the pound needs the growth evidence alongside inflation, employment and the relative outlook for other economies.

The quarterly release is consistent with Blue Book 2026, which ONS says will be published on October 30. Keep the September 30 publication date separate from the April–June reference period when describing the news. ONS: UK quarterly national accounts, April–June 2026 The next analytical task is to compare later monthly activity and labour-market releases with this revised baseline. For a claim about the currency response, document the release time, relevant market prices and competing announcements. A GDP revision does not establish that sterling rose, that a rate decision changed, or that stronger growth persisted into September.
A modest upward revision, with an important historical boundary
Q1 growth remains 0.6%. In Q2, services expanded 0.6%, construction rose 0.8% and production declined 0.1%. The same release puts real household disposable income per head up 1.0% and the household saving ratio at 8.8%. These figures describe separate parts of the accounts; they are not interchangeable measures of GDP growth. ONS: UK quarterly national accounts, April–June 2026
The first estimate had shown services growth of 0.5%, construction growth of 0.3% and no change in production. Comparing the releases shows where the picture changed. It also prevents an outdated sector breakdown from being attached to the new headline, which would combine incompatible vintages of the national accounts.
