Since 2012, the United Kingdom has moved from having essentially a single, uniform approach to social security to one in which there is much more extensive variation at country and local levels. The two tables below provide an at-a-glance summary of the areas where differences can be found in 2026 – which is not to say that these differences are always widespread or large.

Two significant, connected splits can be identified: one geographic, the other by category of social security benefit. In the case of benefits delivered by the Department for Work and Pensions in England and Wales, the DWP approach provides a ‘default’ model, from which Scotland and/or Northern Ireland may in some cases diverge; as a rule, Wales follows the same path as England, and there is no variation within England. For those benefits delivered by authorities other than the DWP, there can be considerable variation both between the four UK countries and within England.

Overall, while Northern Ireland has by far the most extensive devolved social security competences, it is in Scotland that devolution has resulted in the greatest difference to the benefits available. Devolved government plays a minor role in social security in Wales (although the new Welsh Government has ambitions for this to change) and none in England. Conversely, local government plays a bigger role in social security in England than elsewhere, and England has the most extensive local variation in the support available. Local government delivers many (although not all) of the same areas of social security in Scotland and Wales as in England, but devolved government places greater constraints on local autonomy. In Northern Ireland local authorities have no role in social security.
