Hello, I have used 5k of my Stock&shares ISA with one provider (which I use since 2020) at the beginning of the fiscal year, however, I have since then decided to put my money in another provider due to lower fees, but haven’t transferred the old one as most stocks are not transferable to the new provider. Is this ok providing that I don’t go over £20k? If not, what should I do not to lose the ISA benefits?
