Scottish Provident has added ABI+ definitions and reduced the rates on its life and critical illness cover.
It has added multiple sclerosis with pay-out after three months of persisting impairment, previously six months.
Accident hospitalisation and third degree burns cover have also been included.
Jennifer Gilchrist, senior product development manager at Scottish Provident, said:
"Scottish Provident has been urging people to take more of a financial initiative and ensure that they purchase valuable protection.
"By reducing the cost of the majority of our rates, it is now even cheaper to take out protection."
There are now 45 definitions with 41 paying the full amount of cover. A further four will pay out a maximum of £15,000 or 20% of the main critical illness benefit, whichever is lower.
Successful claims for additional covered conditions will not reduce the original amount covered by the policy.
