Social Security Legislation 2025/26 Supplement

This Supplement updates to December 8, 2025 the four-volume work Social Security Legislation 2025/26.

Part I of the Supplement contains new legislation, presented in the same format as the main volumes. Parts II, III, IV and V contain the standard updating material – a separate Part for each volume of the main work – which amends the legislative text and key aspects of the commentary, drawing attention to important recent case law, so as to be up to date as at December 8, 2025. Part VI comprises the cumulative updating material for Volume V, Income Support and the Legacy Benefits, which was last published in the 2021/22 edition.

Among the many changes, particularly noteworthy are those with respect to:

• Further case law developments in relation to universal credit, now the principal means-tested social security benefit;
• Extensive new Upper Tribunal case law on the scope of personal independence payment and the meaning of the daily living and mobility descriptors;
• Significant changes to devolved social security provision in Scotland;

Part VII, the final section of the Supplement, gives some notice of changes forthcoming between December 8, 2025 and the date to which the main work (2026/27 edition) will be up to date (mid-April 2026), along with the April 2026 benefit rates.

As always, the editorial team has brought its academic and adjudication expertise and its knowledge of tribunal practice to produce a work updating and expanding a guide which will be essential reading for DWP and HMRC decision makers, First-tier and Upper Tribunal judges, First-tier Tribunal members, barristers and solicitors working in the social security field, welfare rights advisers and students.
