The proportion of assessed contribution, the amount the United Kingdom is required to pay to the World Health Organization (WHO), which excludes any additional voluntary contributions, is based on the United Nations (UN) scale of assessments. The Government believes that UN member states should share fair and balanced financial responsibility for supporting international institutions through “capacity to pay”, as their national economies develop and presses for reform to this end. In 2012 the UK successfully negotiated a reduction in our rate of contribution to the UN Regular Budget, falling from 6.6% to 5.2%. This generated savings of around £100 million a year for HM Government through linkages between the scale rate for the Regular Budgets and those used to calculate member states’ contributions to the budgets of many other UN bodies, including the WHO. This was applied to the UK’s assessed contribution to WHO, with effect from 2014, the start of the current biennium.
