Why Did Centrica Plc LSE:CNA Fall 0.47% on 27 October 2026?

Centrica Plc — LSE:CNA closed 0.47% lower on 27 October 2026, with the shares at 149.15p after a decline of 0.70p on the day.

London equities weakened on Tuesday, with the FTSE 100 down close to 1% as results-driven falls in HSBC Holdings (LSE:HSBA) and Reckitt Benckiser (LSE:RKT) dragged on the index. Firmer UK purchasing managers' index readings for October offered some support to the domestic growth picture, but caution ahead of Wednesday's Autumn Budget and the Federal Reserve's policy decision set the tone. Rate-sensitive sectors such as utilities were also watched closely ahead of the Budget and this week's central bank decisions.
