Yes, most ISAs, including stocks and shares ISAs are covered by the FSCS up to £85,000 per person, per institution. This means that in the unfortunate event that your ISA provider or fund manager were to go bust, you'd be covered up to that amount. However, this does not mean that you are protected if the investments in your stocks and shares ISA were to lose value from fluctuations in the stock market. Always be aware that stocks and shares ISAs put your capital at risk, and you may get back less than you originally invested.
