Insurance and Investment

GAD provides actuarial advice to government departments, public bodies and local authorities on life, general and health insurance related matters.

Insurance and risk transfer

Our analysis and advice also applies to a wide range of challenges ranging from the impact of climate change to social care funding. We value contingent liabilities (working out what organisations could be financially liable for in the future) and we offer advice on financing solutions for high impact, low probability events (like natural disasters). More information is available about insurance and risk transfer.

Investment and risk

We provide advice on investment aspects of pensions and insurance and undertake specialist projects on the management of risk within UK government departments and financial institutions. We help organisations understand the investment risks that they are exposed to and how best to invest to meet their objectives.

We publish blogs about issues around actuarial work and the investment industry on Actuaries in government. Find out more about what we offer in investment and risk.

Data science, Modelling and Quality Assurance

We provide advice and specialist support to inform effective decision-making across a full range of policy areas.

Data science

We use interactive dashboards, maps and visualisations to help inform strategic decisions and identify trends. Data science is central to our traditional actuarial work and now permeates all areas of government work. Advanced techniques include machine learning to analyse large data sets and powerful visualisation packages. Find out more about GAD’s data science offer.


GAD provides advice on financial and demographic modelling, as well as other bespoke modelling services. We provide guidance at all stages of the modelling process, from designing a model that is fit for purpose through to clearly communicating the significance of the outputs.
