The tool allows advisers to compare new and historic individual and business cover policies and include the rating views of independent experts.
The service is part of a range of resources designed to make time-pushed advisers business more efficient.
It comes after suggestions that mortgage brokers should try to broaden the range of services offered to clients.
Gemma Harle, protection and mortgage managing director at Intrinsic (pictured), said: “The market for critical illness policies is continually developing and it can be tricky to ascertain which policies are more favourable for clients without medical expertise.
“With a myriad of things to keep track of, advisers are pushed for time.
“With the new tool advisers can quickly and confidently compare the differences between complex policies based on the most common causes of UK claims in 2017.
With oversight from independent experts, advisers and their clients can rest assured that they are getting a policy that suits their needs and time of life.”
Zahid Bilgrami, chief executive of Defaqto, added: “We are delighted to have worked closely together with Intrinsic to develop a critical illness comparison (CIC) tool for financial advisers.
“The Defaqto CIC tool helps advisers create suitable outcomes for clients through comparing historic illness definitions of an existing policy with a new one.”
