All new quotes given to customers as of yesterday will show the gender-neutral premiums for both males and females and will be guaranteed for 90 days.
On average, female premiums have risen by just under 20%. The premium change will vary depending for each individual customer so L&G say advisers should check by getting a quote.
Stuart Welch, actuarial director for individual protection, Legal & General, said: “As the leader in the protection market we’re moving to gender-neutral pricing early to provide the certainty we believe advisers and their customers need.
“The new quotes come with a 90 day guarantee so advisers can begin to think about next year’s pipeline with that clarity. It's likely that the market will see some volatility in the aftermath of all the different moves to gender-neutral rates and this will continue into 2013.”
