FX.co ★ UK Factory-Gate Inflation Accelerates as PPI Output Climbs to 4.6% in September

Producer price inflation at the factory gate picked up in the United Kingdom in September 2026, with PPI Output rising 4.6% year-over-year, up from 3.7% in August. The data, updated on 21 October 2026, indicate a further acceleration in price pressures at the producer level compared with the same month a year earlier.

On a year-over-year basis, the previous reading for August 2026 reflected a 3.7% increase in output prices versus August 2025, while the latest September figure shows a 4.6% rise compared with September 2025. The move higher suggests that cost pressures within the production sector continued to build as the third quarter drew to a close, with September marking a stronger annual gain than the month before.

The year-over-year comparison framework highlights that both the “previous” and “actual” readings measure changes against the same months a year earlier—August and September 2025, respectively—underscoring a clear upward shift in producer-level inflation momentum as of September 2026.
