Storm Arwen: latest power disruption information

29 November 2021


As of 13:00 today (Monday 29 November), power has been restored to around 870,000 homes. Around 155,000 homes are currently without power as a direct result of damage caused by Storm Arwen.

Thousands of engineers are working to restore power to customers as quickly and safely as possible. In addition, and where safe to do so, energy networks are also deploying helicopters and drones to identify and assess damage.

Engineers are continuing to uncover snapped electricity poles, downed wires and other complex faults. In some areas of the country the damage is some of the worst seen since 2005. Snowfall in some areas is making access very difficult.

Safety advice

The energy networks have issued important safety advice after a number of power lines were brought down and are urging those with medical needs to contact them.

Network operators are working with local resilience forums and co-ordinating a response with local authorities, British Red Cross and emergency services.

Supporting customers

  • Energy networks are working with British Red Cross and local resilience forums to provide extra help and support.
  • Welfare centres have been set up in some of the worst hit areas, providing hot food and respite.
  • Dedicated teams are contacting vulnerable customers to offer support.
  • Contact centres are working around the clock to respond to enquiries by phone and on social media. Due to high call volumes, customers are urged to monitor social media for updates wherever possible.
  • Customers who remain without power should consider making alternative arrangements and staying with friends or family where possible.
  • Customers can monitor progress by following their network operator on Twitter. Enter your postcode at to find your local network operator’s details, including their social media channel.
