Bright Grey, the protection specialist arm of Royal London Group, is to implement the new ABI standard critical illness definitions from the start of next week.

The new definitions aim to future proof critical illness products and make it even easier for consumers to see what is covered.

At the same time, Bright Grey is introducing four new illnesses to its critical illness cover: open-heart surgery; progressive supra nuclear palsy; severe lung disease; and traumatic head injury.

Commenting on the changes, Roger Edwards, Bright Grey's product director, said: "The ABI definitions should bring greater clarity for customers through the revised headings. Like all providers, we've been through a reassurance re-broking process in order to introduce these new standard definitions, and we've taken the opportunity to investigate where we can include new illnesses and go beyond some of the definitions. For example, we've omitted the requirement for there to be typical clinical symptoms for the definition of heart attack."
