Stigma in the UK social security system is more than a matter of hurt feelings, it has deep and measurable consequences for individuals, communities, and the system itself. It can push people to delay or avoid claiming the support they are entitled to, worsening financial hardship, fuelling debt, and undermining health and wellbeing. For government and society, this can mean higher downstream costs in healthcare, social services, and crisis support, alongside the economic losses of reduced participation in work and community life.
