The momentum of the UK economy showed a modest improvement in early autumn, according to the latest reading from the National Institute of Economic and Social Research (NIESR). The institute’s Monthly GDP Tracker indicated that estimated economic growth reached 0.7% in September 2026, up from 0.5% in August 2026.
The updated figures, released on 15 October 2026, suggest a slight acceleration in activity as the third quarter drew to a close. While the tracker is an estimate rather than an official GDP release, it is closely watched by analysts and investors as a timely gauge of underlying growth trends in the United Kingdom. The move from 0.5% to 0.7% over the month points to a firmer near-term outlook, as markets assess how sustained this pickup might be in the coming months.
