Great Britain retail sales volumes fall 0.4% month on month in September 2026

Great Britain’s retail sales volumes fell 0.4% month on month in September 2026, reversing August’s increase, according to the Office for National Statistics. The figures cover England, Scotland and Wales, excluding Northern Ireland. Sales volumes excluding automotive fuel declined 0.7% from August. Both measures are seasonally adjusted and track the quantity bought, so the September declines indicate weaker retail activity rather than simply lower nominal sales receipts.

The reversal followed August increases of 0.7% including automotive fuel and 0.9% excluding it. September’s monthly declines matched those recorded in July for both measures. That return to contraction makes August look like an interruption in recent weakness rather than evidence of sustained acceleration. It also leaves both measures alternating between contraction and expansion over July, August and September.

The longer April-to-September record is mixed rather than uniformly weak. Both measures contracted in April before expanding in May and June. September therefore adds to evidence of an uneven retail performance, but does not establish a continuous downward trend. The distinction matters: a negative monthly reading shows less quantity bought than in the preceding month, not the cumulative change over this six-month period.

A weaker demand signal beyond fuel

The decline excluding automotive fuel shows that September’s weakness was not confined to the fuel-inclusive measure. This supports a judgment of softer demand across the retail aggregate beyond fuel, although it does not identify which types of shops drove the fall. The smaller decline in the headline measure cannot be translated directly into fuel-sector growth because the two aggregates have different weights.

For retailers, lower quantities bought could reduce the need to replenish stock if the weakness persists, potentially transmitting softer customer demand to suppliers. That is a conditional implication, not an observed outcome. The alternating monthly results argue against treating September alone as a lasting change in household demand. These figures also cover retail goods rather than consumption across all services, limiting how far the signal extends to overall consumer activity.
