Philosophy application with no related subjects

Have you looked at the entry requirements for any Philosophy degrees - are there any specific A level subjects mentioned?

None of the subjects you listed are any more related to philosophy than the ones you are taking.

The potential issue may lie in the combination of business studies and economics, which historically a few universities have disliked due to overlapping content. At present the only one I'm aware of which specifically states this is LSE though.

I think that having essay-based subjects will still work in your favour if you are hoping to choose another essay-based course. Nonetheless if you're having doubts, focus in your personal statement (if you are still yet to submit it) how you're drawn to philosophy outside the scope of what your A levels brought you. I think that the content covered in the alleged 'preferred' arts-based subjects mentioned in above comments only really have the advantage on theoretical writing practices and covering more objective topics and themes than in business and econ.

Given how you say that you have already achieved your A level grades, I'm assuming that you're doing some kind of gap year? Consider how you're spending that and how that can be seen as building onto your interest towards your degree. You've gone from being sixteen and choosing one lot of subjects to have pivoted and wanting to do philosophy - how did this change develop? Have you always wanted to end up doing law, but just wanted to reach it in a different way, or build up your skillset by doing a degree that strays from the skills you get at A level to make you more well-rounded? If you can explain and justify the pivot, then I'm sure that you can equally justify why you should be accepted onto a philosophy course in the same way as everyone else.

Any ideas about which universities you fancy?

Not sure really. My issue is how universities will see my subjects, because nominally my grades can take me anywhere, but that isn't the case truly. I'm thinking of Bristol, Durham, Warwick as aspirational choices maybe. I will probably apply to a couple first, so the choices after will be informed by possible decisions I've already received.
