I've opened a new shares ISA with Wealthify (Aviva) in addition to the Vanguard one (I don't like having all my eggs in one basket)! Was easy to open, choose level of risk etc....just proving challenging to get Natwest to transfer the funds across (I understand they have to be very sure I'm not being scammed but still!). They give some cashback and their fees are low (researched on MSE)
