Sources: 8. Developments: 2. Electricity supply failures in the London region have caused recurring disruptions to both residential power and transportation networks. In mid-September, a fault between Stevenage and Finsbury Park led to significant rail delays and cancellations for multiple operators, including Great Northern, Thameslink, and LNER. Commuters were advised to allow for substantial extra travel time due to the impact on services entering London. On October 5, a separate underground cable fault caused a major power outage affecting approximately 5,000 homes and businesses across North London, East London, and the City. This outage also disrupted transport infrastructure, causing departure screens to fail at Liverpool Street Station and leaving some platforms, such as Essex Road Station, without lighting. UK Power Networks worked to restore service, returning electricity to most customers by midday. ## Timeline ### 2026-10-06: London power outage affects 5,000 customers and disrupts transport A faulty underground cable caused a power outage in London on October 5, affecting over 5,000 customers and disrupting transport services, including lighting and information screens at major stations. 6 sources. https://clstr.news/cluster/london-power-outage-affects-5000-customers-and-disrupts-transport ### 2026-09-18: Electricity failure causes rail disruption near London An electricity supply failure between Stevenage and Finsbury Park is causing major rail disruptions for several operators, including Great Northern and Thameslink, affecting services into London. 2 sources. https://clstr.news/cluster/electricity-failure-causes-rail-disruption-near-london --- Cite as: Electricity failures and transport disruption in London.
