UK GDP Grew 0.7% in Q3 2026 as September Annual Growth Hit 2.1%

The United Kingdom’s economy grew 0.7% in the third quarter of 2026 from the prior quarter, while September gross domestic product was 2.1% above its year-earlier level.

A quarter-over-quarter reading compares one quarter with the quarter immediately before it. The 0.7% figure therefore measures Q3 relative to Q2. A year-over-year reading compares a period with the same period a year earlier, so September’s 2.1% figure uses September 2025 as its comparison point. It does not mean GDP rose 2.1% within September alone.

September’s annual growth rate increased from 2% in August, a rise of 0.1 percentage point. August GDP also grew 0.1% from July, a month-over-month comparison. That reading differs from August’s 2% annual rate and the 0.7% quarterly figure. August GDP grew 0.1% month over month.

Together, the figures show quarterly expansion and faster annual growth in September than in August.
