anything that will distinguish you from the crowd - some other qualification is one way, especially if you want to get into one of the larger employers, but otherwise I think some relevant work experience may be the best way to go.
First, look at the job ads on 'The Actuary' site and speak to the recruitment consultants. If that doesn't get you anywhere, ring around or email or write to the relevant people (heads of actuarial/risk management departments etc), explain that you have a degree in actuarial science and are willing to work doing anything in a relevant dept for up to a month. If you try 50 places i'd be amazed if at least a couple of places didn't invite you in, and probably more like 5 or 10. I'd probably ring up, ask for the name of the head of the relevant dept (or maybe go the their web site or whatever) and email them if you can get an email address, otherwise write to them snail mail style.
I'd emphasise your excel (and any access or VBA etc) skills by the way if you try that by the way.
