About our services

Our expert technical skills, high professional standards and industry sector knowledge enable effective decision making and policy development.

The Government Actuary’s Department (GAD) delivers impartial, expert analysis to help government navigate risk and make better decisions. We combine deep technical expertise with practical insight to solve complex financial challenges across the public sector.

What we do

GAD provides actuarial advice and analysis to the UK government, devolved administrations, local authorities and the wider public sector. Our multidisciplinary teams of actuaries, analysts and specialist consultants bring expertise across pensions, investment, insurance, financial risk, climate risk, social security, workforce planning, disaster risk, data analytics and health and social care.

Our work underpins some of the UK’s most significant financial commitments, including public service pension schemes that benefit around 15 million individuals – including police, firefighters, healthcare professionals, teachers and civil servants. We support government departments across a wide range of initiatives, from reporting on Great Britain’s National Insurance Fund and State Pension age to climate risk analysis, estimating future clinical negligence claims, advising on school insurance alternatives and providing expertise for disaster risk finance.

Our services across a range of areas are described below. To find out more about the work we do, please see our collection of case studies.
