Actuary without a maths degree?Watch
If you're applying to top tier unis such as Cambridge/Oxford/Imperial/Warwick then your chances are significantly reduced however you can get into most other Russell groups
Having a degree in English literature might even give you a slight advantage in the later exams, where a large part of what is required is to explain and synthesise arguments.
I agree that it may also be more difficult to find your first actuarial position with an English literature degree. But you can take the first two (I think?) actuarial exams without actually becoming a member of the IFoA and I suspect that if you had passed those, employers would be a lot more willing to consider you. Of course you’d have to pay for the exams yourself.
On balance, I’d still recommend a mathy degree but you definitely can qualify as an actuary without one; it will just require a bit more work.
(Disclaimer: I’m an IFoA qualified actuary but I don’t work in the UK.)
