SSEN publishes Annual Vulnerability Report dated 31 July 2026

Scottish and Southern Electricity Networks (SSEN) has published its Annual Vulnerability Report for 2025-26, listed in its Consumer Vulnerability document library with a date of 31/07/2026¹. The same date appears on two accompanying documents: a RIIO-ED2 Vulnerability ODI Assessment Year 3 covering letter and a RIIO-ED2 Vulnerability ODI Assessment Table 6 for Year 3¹.

SSEN states that it will produce an Annual Vulnerability Report each July, providing an update on progress against its commitments to customers and communities in vulnerable situations, and on its performance¹. The report covers how the network has increased the number of households on its Priority Service Register, support provided through partnership programmes focused on fuel poverty and the transition to net zero, winter preparedness activities and changes made to improve its winter response, and other initiatives to support customers in challenging situations¹.

"This report is supported by an assurance report completed by SIRIO, an independent assurance provider"

The library lists the report as a PDF of 1.9 MB, the Year 3 covering letter as 346.8 KB and the Year 3 Table 6 as 259.1 KB, all dated 31/07/2026¹. Earlier editions are also listed: a 2024-25 report with its Year 2 covering letter and Table 6, and a 2023-24 report with a Table 6 and a Year 1 covering letter¹.

The figures behind the report, including the number of households added to the Priority Service Register and any performance figures against the RIIO-ED2 vulnerability outcomes, are not given in the document library listing¹. The contents of the report PDF itself have not been reported in the listing beyond the topics it covers¹.

Why it matters for households

SSEN is the distribution network operator for central southern England and the north of Scotland, so its vulnerability work applies to homes in those areas that take electricity through its network, regardless of which suppliers they buy their energy from. The Priority Service Register is the mechanism networks and suppliers use to record households that need extra help, for example during a power cut, and being on it can bring advance warning of planned interruptions and priority during restoration. The report is SSEN's own account of how many households it has added to that register and what support its partnership programmes have delivered, which is the main public measure of whether that help is reaching the homes that need it. The winter preparedness section covers how the network responds when storms or cold weather interrupt supply, which is when a household's energy independence is most exposed.

What happens next

SSEN states that it will produce an Annual Vulnerability Report each July¹. No date for the next edition has been reported¹.
