Don't worry, nearly there! Self-select ISAs can be either Maxi or MINI share ISAs. Basically, they allow the investor to choose their own portfolio of stocks and shares, unit trusts, etc, rather than be limited to the ISA provider's selection.
Self-Select ISAs are available from Stockbrokers, but remember that you will have to do your own research into investments. Some brokers will advise, but be prepared to pay extra. There are some disadvantages. Firstly, they tend to be more expensive to run, as charges normally attract VAT, which isn't redeemable under ISA rules. Also, be wary of hidden charges such as admin (for meetings, annual accounts, reports, etc) dealing costs, charges for employee share options/SAYE, and additional commission for investing more than 50% in shares outside of the EU.
If you wish to purchase a Self Select ISA, please contact a stock broker or contact us for a referral.
