Interested in learning more about self-select Stocks and Shares ISAs? Here’s a look at how they work, and how to select one.

What is a self-select Stocks and Shares ISA?

A self-select Stocks and Shares ISA is an ISA account that enables you to pick your investments yourself.

Sometimes called do-it-yourself (DIY) ISAs, they are aimed at more experienced investors who want to make their own investment decisions.

Self-select Stocks and Shares ISAs typically offer access to a range of investments including stocks, investment funds, investment trusts, exchange-traded funds (ETFs), and bonds.

They are offered by a range of companies including Hargreaves Lansdown, AJ Bell, Interactive Investor, Barclays, and Fidelity.

Advantages and disadvantages of self-select ISAs?

Self-select ISAs have both advantages and disadvantages.

Advantages include:

  • More control – With these accounts, you decide how your money is invested.
  • More investment options – Self-select ISAs tend to offer access to far more investments than managed ISA accounts offer.
  • More flexibility – With these ISAs, you have a lot of flexibility.

Disadvantages are:

  • Risk levels are higher – Self-select ISAs can be higher risk than other types of ISAs. You are responsible for your own investment decisions and there is no guarantee that you will make money.
  • More time is needed – Managing a self-select ISA takes time and effort. With these ISAs, you need to keep an eye on your investments.
  • Platforms can be more complex – Self-select ISA platforms tend to be more complex than managed ISA platforms.

Self-select ISAs vs managed ISAs: what’s the best option?

The best type of Stocks and Shares ISA for you will depend on a few factors, including:

  • Your investment experience – Self-select platforms are more suited to those with a lot of investment experience who are comfortable managing their own money. By contrast, managed platforms are generally more suited to beginner investors who don’t want to choose their own investments.
  • The time you have to devote to managing your investments – Self-select platforms are more suited to those who have time to manage their money. If you don’t have the time to manage your investments, a managed ISA product may be more suitable for you.
