how much dividend do they pay if its well under £500 (HMRC tax threshold) then transfer them to HL they have a standard HL fund and share account that has no monthly fees. (dealing fees are £12.95, but regular monthly saver is zero fees if you intend to buy more shares)
remember capital gains is now only £3k in tax year 2024/5, so good to consider tax implications if you have made large increases or expect to in the future.
ps. you generally cant transfer shares into an isa, hence you would sell and buy back which may likely trigger capital gain, HL Stocks and Shares ISA. There’s no charge for holding cash, yearly charge for holding investments is a maximum of 0.45%.
