Don't listen to the above user. With 4 A*'s predicted and an A in EPQ you will have a good shot at UCL; maybe not Cambridge because they usually reject people who don't take further Maths. I'd still apply to UCL and LSE and even Oxford (but note Oxford doesn't do a pure economics program, they do Economics+ Management).
Any except LSE; without FM you aren't competitive for LSE single honours economics, unless you weren't able to take it because your school doesn't offer it. Most years 95% of successful applicants to LSE single honours economics have AS or A-level FM. Note that for some of the joint honours courses there lack of FM is less of an issue (usually the ones that are joint with essay based subjects, and PPE). While note having FM is less ideal for e.g. Warwick and Cambridge, there isn't such a huge gap in success rates between those with and without FM as at LSE. If you wanted to take a gap year and take FM then, you could also add LSE to the list though and apply to literally any economics course in the UK.
