Industry watchdog Ofgem claims that electricity networks provided "unacceptable service" to thousands of customers in the wake of Storm Arwen.
Nearly one million homes were left without power after winds of 100mph caused widespread disruption, uprooted trees and damaged power lines across northern England and Scotland from November 26, 2021. In some areas, power outages lasted for more than 10 days with many customers complaining of poor communication from their electricity suppliers.
An independent review was carried out by Ofgem which examined whether the power outages could have been prevented, if correct and timely information was given to customers, whether power was restored quickly enough, and how customers were supported after the storm. It found that staff at distribution network operators worked hard in challenging conditions.

However, it concluded that thousands of electricity customers were provided with an "unacceptable service". Ofgem chief executive Jonathan Brearley said: “Distribution network companies faced challenging conditions in the aftermath of Storm Arwen, and I pay tribute to the many colleagues in those companies who supported customers and worked to get them back on power as quickly as possible.
“However, it was unacceptable that nearly 4,000 homes in parts of England and Scotland were off power for over a week, often without accurate information as to when power would be restored. Network companies need to do better, not just to prevent power disruptions, but to ensure that, when power is off, they work smarter to get people back on power quicker, and keep customers informed with accurate and timely information. This is the very least customers should be able to expect.
“The frequency of extreme weather events is only set to increase so it is really important that industry, and those involved more widely, learn from Storm Arwen to better respond in future.”
The Ofgem review found:
- Some affected customers remained off power for an unacceptable amount of time, received poor communication from their network operator and compensation payments took too long.
- Plans in place to deal with the storm were not sufficient to deal with the scale of the damage.
- Northern Powergrid did not directly contact vulnerable customers enrolled on its Priority Services Register prior to Storm Arwen, which should have been carried out as part of its winter preparedness campaign.
- The same firm accepted the performance of its call centre fell below the standards it should have been able to meet during a severe storm, potentially breaching its licence.
- Limited remote monitoring stopped firms from understanding the full scale and complexity of faults.
- There was some correlation between the age of electricity poles and how badly damaged they were in the storm, although this needed further examination.
- Three firms – Northern Powergrid, Scottish and Southern Electricity Networks and Electricity North West – paid nearly £30 million in direct compensation to affected customers after the storms and will now pay a further £10.3 million in voluntary redress payments to the affected communities.
Following the investigation, Ofgem has recommended that firms submit their winter plan so they are prepared for the future. It also recommends that they stress-test their websites and call centre to ensure adequate capacity during severe weather events.
Business and Energy Secretary Kwasi Kwarteng said: “Storm Arwen was one of the most extreme weather events in decades, and I’m grateful to all those engineers, armed forces personnel and volunteers who worked night and day to get people reconnected to power.
“However, it’s clear that thousands of customers were badly let down by electricity network companies, which is why I launched this review to identify and address any failings. This action plan will ensure better preparedness for future storms, boosting the security of our electricity system and protecting families.”
