$11.2 billion in gross written premiums (2018)

With a 17% Market share of life Insurance and savings products as well as a 10% market share of general insurance, Aviva is the largest insurance provider in the UK.

The company's major market, accounting for 48% of its clientele, is Britain, but it also has operations in 16 other countries throughout Europe and Asia and is Canada's second-largest insurer.

With little under a million annuities, a sort of investment that insurers cover with a policy, and fixed-index life insurance plans, Aviva used to be active in the US market.

But in October 2013, it transferred ownership of this division of the company to retirement savings firm Athene Holding Ltd.
