Bright Grey is to revamp its critical illness (CI) cover by improving definitions around the five most common reasons for claim.
The insurer, which is part of Royal London, is improving definitions around cancer, heart attack, stroke, multiple sclerosis, children's critical illness cover.
Bright Grey said it is focusing on these definitions because almost 90% of its critical illness claims are for these five conditions.
The improvement follows other recent changes, including a dedicated case manager and an underwriter for every client application.
From October, Bright Grey will start to communicate the definition changes to advisers through a new marketing campaign.
The campaign titled "We care, you care, take care" will reach advisers across a range of channels including digital and print advertising; also email promotions.
Debbie Kennedy, head of protection proposition design at Royal London said: "We've focused our improvements on the five most common conditions that affect clients, because we want to offer cover that's better value; designed to pay more claims; and gives clients the emotional support when they need it most."
Meanwhile, advisers' clients and their immediate families will continue to have access to the Helping Hand support service at no extra cost, from the day their Bright Grey menu or relevant life plan starts, even if there's no claim.
Royal London's group chief executive told COVER that advisers would see the changes to its protection lines before the general public.
