You're probably aware of the American Express name as a provider of credit cards, as it's one of the largest and oldest card providers in the world.
American Express specialises in premium cards. Most of its cards charge a monthly fee in return for a range of additional services. But it also offers everyday cards such as its Basic Card.
Amex previously offered insurance products, but has now entirely withdrawn from the UK insurance market. Existing policies won't be affected, but you can't now take out a new policy of any type.
