Good that you are looking at this before choosing A level subjects. Part of my job is attending school and uni carers fairs, and often talk to people who have chosen too narrow a range or the wrong subjects for specific careers that have set their heart on, as well as others who don't realise that for a lot of courses or careers you can be pretty flexible about subject choice.
I suggest you look at the course requirements at a number of universities for each of the subjects you have mentioned, plus a couple more general courses such as engineering or business. A couple of hours online research will give you a good indication of the essential and desirable subjects, especially if you choose a broad range of unis.
A quick way of doing thus is to look at the Which University website. As well as offering general advice (including A levels choices), it also has info on all the universities that currently offer specific degrees. Search for a degree subject then pick 4 or 5 unis that you have heard of and look at the course information. The required subjects and grades (and possible careers) will be at the top of the page, and the most popular actual subjects, achieved grades and initial job destinations will be at the bottom. Not as definitive as the uni websites themselves but great for early way to see what A level subjects would give you the most choice.
