How necessary is further maths for econ?

Im picking my course options for sixth form and i have chose maths, physics and economics. I want to do economics at uni, more specifically, Warwick or UCl, and i was just wondering, how important is further maths actually? I know it does help, but my college do maths in year 12 and further maths in year 13, and i really dont like that structure and i feel i wouldnt do as good as like any other a level in two years. If that wasnt the case, i woudve taken further maths no problem. So, is it worth really taking the risk and picking it for that (presumably small) advantage?
Thank you.

Just thought I'd add that if your only concern is doing Maths in Year 12 and Further Maths in Year 13, then it may be worth still giving it a try. That's how I did it and most of my class found this structure much easier as we didn't have to worry about FM prerequisites, we could apply with an A-Level already under our belt, and we could focus on just the one A-Level in Year 12. Also, if you change your mind, you could just drop back to single Maths and just be ahead for a couple of months. The deadline to withdraw from an A-Level registration is often April at the latest (though you may incur a late fee), at which point you may have a better understanding of how well you'll be doing.

But if you drop further maths in year 12, after a few months then you are only doing 2 a levels, how will you be able to swap to something else soo far in?
