Exeter Family Friendly has backed COVER and the Protection Review's IP Campaign against the use of occupational definitions in income protection policies.
The provider, which only offers own occupation cover across all plans regardless of occupation, said, that without exiting controversy, it wanted to emphasise the importance of this issue to the industry as a whole.
Nick Jones, brand & marketing manager at Exeter, said: "Exeter Family Friendly welcome and support the Cover campaign for insurers to abolish the use of ADL's.
"We think an Own Occupation definition is one of the core benchmarks of an income protection plan, so to deliver anything less would simply not be in the consumer or advisers best interest.
"There is no point in cover that is ultimately going to deliver less than, or something different to what the customer expects.
"In our view, this is what ADL's often do and are an example of potential disaster for the whole industry, not just those insurers who use them."
