The idea of pooling resources and sharing risks to provide universal services according to need not ability to pay was at the heart of the post-war settlement. However, decades of market ideology and deep spending cuts have left most services starved of power and resources. Universal Basic Services (UBS) offers a principled framework for policy and practice that aims to ensure everyone has access to life’s essentials. Based on need theory it combines universality with sufficiency to provide a secure social foundation for all within planetary boundaries. Needs are met in different ways, combining collective and individual measures, as illustrated by examples of childcare, housing and food. UBS can be combined with an income guarantee to ensure no-one’s income falls below an agreed level of sufficiency. Cash and services, which represent a ‘social wage’, are best understood as two sides of the same coin, supporting rather than competing with one another.
