The group have an age limit of 74, which is the highest boundary for people applying for critical illness cover in the entire market.
The maximum sum assured limit is up to £4m.
John Wilkinson, Protection Director, said: “We’ve spoken to advisers about what’s important to them and their customers when it comes to critical illness cover.
“The quality and number of ABI+ definitions were high on the list along with the number of conditions covered, speed of underwriting and the inclusion of partial payments.”
Aegon’s insurance policy now includes 11 critical illness conditions including two children’s definitions, such as partial loss of sight, children’s death benefit and critical fracture cover, for specified fractures.
Further enhancements include an increase in which HIV tests are routinely requested from above £1m to above £1.5m on critical illness and life cover applications.
In 2012 Aegon paid out on 91% of critical illness claims made, amounting to £24.3m.
60% of claims paid for were cancer, while average age of a claimant was 46.
