The best I could do in 5 minutes googling was newspapers complaining that, on average, men still pay more... because they drive (on average) further, in more expensive cars.
And rumours that they are setting the rates for different professions as a way to get around the rule... huge differences like this:
Dental Nurse Less than 1pc male £840
Solicitor 59pc male £848
Sports and leisure assistants 56pc male £880
Civil engineer 92pc male £910
Social worker 21pc male £920
Plasterer 98pc male £950
I had an idea that retirement annuities etc, which are a much bigger deal, were much more regulated & could only price based on a few numbers. But I don't have a link.
