Old Mutual Wealth has paid 100 per cent of life claims for the eighth year in a row.
The provider released its latest life and critical illness claims data showing it paid all of life claims and 94.6 per cent of all critical illness claims in 2017.
This means Old Mutual Wealth have honoured 15,067 claims with a total of more than £976m paid - over this eight-year period.
Paul Roberts, head of protection at Old Mutual Wealth, said: "Claims information is important to show the public that insurers pay out for most of the claims we receive.
"Our research has shown that there is a common misconception among customers on the amount of claims that are paid.
"Just 6 per cent of those surveyed thought insurers paid out more than 90 per cent of critical illness claims."
The figures found that throughout last year Old Mutual Wealth helped 341 families and paid out £60.3m in life and critical illness claims.
The average claims size was £152,704 for life insurance and £167,748 for critical illness.
Over 78.5 per cent of critical illness claims were made for the three conditions.
This included cancer, which accounted for 55.8 per cent, stroke made up 12.3 per cent and heart attack was 10.4 per cent.
The average age of claimants was 74 for women and 69 for men.
Alan Chan, director and chartered financial planner at London-based IFS Wealth & Pensions, said: "The 100 per cent pay-out rate for life claims is very impressive from Old Mutual Wealth and it could play a part in encouraging advisers to recommend them over other providers if there is nothing in it in the cost.
"I am all for providers openly publishing their claims data. Sometimes this information is available already but very difficult to find and you have to spend a lot of time trawling through pages and pages to find some reference to it.
"This would then allow a meaningful comparison against the market average pay-out rates for each policy and help advisers choose the better quality covers."
