The UN's regular budget is funded through assessed contributions from its member states, with each country's assessment rate based on a formula that considers factors such as gross national income, population, and UN peacekeeping expenses. The UK is one of the largest financial contributors to the UN and has consistently paid its dues in full and on time.
In addition to its regular budget assessment, the UK also makes voluntary contributions to specific UN programs and agencies, such as the UN Development Programme (UNDP) and the UN Children's Fund (UNICEF). The UK's total contribution to the UN system, including both assessed and voluntary contributions, was over £2 billion in 2021.
The UK's membership in the UN and its financial contributions to the organization reflect its commitment to multilateralism and its belief in the importance of international cooperation in addressing global challenges.
