Hello, I’m currently studying law. There are no specific A level subject requirements for law, but it is advised by many unis that you take at least one essay-based subject as it will help to prepare you for the degree (which obviously, contains a lot of essay writing, and loads of reading). That being said, it’s better for you to stick to 3 A levels than to study 4 so that you can take English. I would recommend either sticking with economics, maths and accounting, or swapping one of them for English.
