Legal & General will move to gender neutral pricing from 21 November.
From that date, new quotes given to customers will show the gender-neutral premiums for both males and females. All quotes will be valid for 90 days from that date.
The insurer said the industry faces huge challenges in managing the amount of pipeline business in the run up to the deadline and that as a market leader it need to be realistic in facing these challenges.
L&G's Gender Response Team, launched in September has completed over 60,000 gender-specific application reviews with the aim of getting business completed before the deadline of 20 December 2012.
Stuart Welch, Actuarial Director for Individual Protection, Legal & General said; "We've seen a fantastic response to our Gender Response Team which we set up in September to ensure applications are processed quickly and efficiently.
"Our priority at all times is to ensure customers know the exact status of their cover by midnight on 20 December 2012.
"Advisers will be able to focus on building their 2013 pipeline as our gender-neutral quotes will be valid for 90 days."
