Just fill your ISA allowance every year, the only other thing you can do is register ACTUAL losses and can go back I believe 5 years on your self assesment. This will improve capital gains allowance if you have registered losses in previous years. So get transferring, get a government gateway account and welcome to self assessments. It's a big job if you are a regular trader..
I have a registered 50k loss with HMRC from a few years ago which I keep in my self assesments, the majority of my portfolio is fortunately in stocks and shares ISA. I have 50k in another share dealing account, next April I shall move to that year's ISA and I doubt I will every be paying CGT on my share dealing account to be honest.
