Investing: Stocks & Shares ISA

A Stocks & Shares ISA is an investment product, so returns depend on the market rather than a fixed savings rate. Here's how it compares on cost.

When you invest, your capital is at risk — the value of investments can go down as well as up, and you may get back less than you put in.

Who they are

Interactive Investor - known to most users simply as "ii" - is a subscription-based online investment platform founded in 1995. Since 2022 it has been a subsidiary of Abrdn, the UK-based investment company. Today ii describes itself as the UK's number one flat-fee investment platform, with assets under administration of £85 billion and over 500,000 customers. The company is authorised and regulated by the Financial Conduct Authority (FCA).

The key thing that sets ii apart from many rivals is its pricing. Its flat-fee model distinguishes it from percentage-based competitors and can be attractive for investors with larger portfolios. The more you have invested, the more that flat fee tends to work in your favour relative to a percentage charge.

Stocks and Shares ISA

The only product in ii's range currently listed on DepositScout is its Stocks and Shares ISA. This is a DIY investing account, not a traditional savings account - there is no fixed interest rate. You choose where your money goes, from a wide choice of over 40,000 UK and international investment options, including shares, funds, trusts and ETFs.

There is currently a promotional offer: you can gift a Stocks and Shares ISA to a family member with no monthly account fee on balances up to £50,000 (terms apply - check the current details on this page).

On protection, the DepositScout data shows that investments are protected up to £85,000 by the FSCS, and uninvested cash held within the account is protected up to £120,000. That higher cash figure reflects the fact that uninvested cash sits in a separate protected pool. It is worth understanding which category your money falls into at any given time.

Is it right for you?

Interactive Investor suits people who want to make their own investment decisions and hold them within a tax-efficient ISA wrapper. Its flat-fee pricing structure will not suit everyone - smaller portfolios may find percentage-based competitors cheaper, while highly active traders will likely prefer more sophisticated platforms. If you are simply looking for a straightforward cash savings account or a fixed-rate bond, ii is not the right fit.

As ever, rates, fees, and promotions change. Check the live details shown on this page before making any decision.
