Since late 2021, the prices for many essential goods in the United Kingdom began increasing faster than household incomes, resulting in a fall in real incomes. This is caused in part by a rise in inflation in both the UK and the world in general, as well as the economic impact of issues such as the COVID-19 pandemic, Russia's invasion of Ukraine, and Brexit. While all in the UK are affected by rising prices, it most substantially affects low-income persons. The British government has responded in various ways such as grants, tax rebates, and subsidies to electricity and gas suppliers.

Poverty in the United Kingdom is the condition experienced by the portion of the population of the United Kingdom that lacks adequate financial resources for a certain standard of living, as defined under the various measures of poverty.
