I've just logged on to see my NEST account and they have included a 'member details' and guess what they have next to 'female', yep 'gender'.
I've sent them the following
In your 'member details; you have have used the word, 'gender'. This is incorrect, my sex is female, gender is a social construct I want to not exist.
You may be wondering why this matters. It matters because in various pieces of legislation but primarily the Equality Act both 'sex' and 'gender identity' are protected in law. For an organisation such as NEST it is vitally important as retirement ages are different for men and women and will continue to be so for some time, if you identify someone by gender you may well calculate a different retirement age as gender can change but sex does not.
Please change this.
