Interactive Investor: Official Review 2025, Pros and Cons

Interactive Investor (“II”) is the second-largest dedicated stockbroker in the UK. The firm is privately owned and serves over 400,000 clients.

Interactive Investor’s spectacular growth has seen the business add over 50,000 new UK clients each year for the last few years. 

Our review concludes that these clients are drawn to Interactive Investor in the search for rock-bottom fees. In 2019, the broker adopted a unique fixed-price model that caps the cost of investing regardless of the size of your portfolio. 

Most brokers charge an account fee based upon a percentage of your account value. This means that as your investments grow, your account charges will grow with it. In stark contrast;  Interactive Investor charges a monthly fee of £9.99, £12.99 or £19.99 for different account plans. These fees are expensive for tiny accounts but translate to an insignificant % for large portfolios, making Interactive Investor the natural home for cost-conscious investors with portfolios worth in excess of £100,000.

Interactive Investor is a stable UK financial institution that falls under the oversight of the Financial Conduct Authority. It was recently announced that Interactive Investor will be acquired by Abrdn, an asset manager based in Scotland that was founded in 1825. This is a further sign of confidence in the long term future of the broker.

In this broker review, we’ll uncover the features of Interactive Investor that have underpinned its success and explain which types of investors may find an Interactive Investor account to be their ideal investment platform.

Interactive Investor is a UK-based organisation. It currently operates from offices in Manchester, Leeds and London, with a total team of over 500 staff.

The firm was founded in 1995 and grew during the following decade which saw an explosion in share dealing online. This has meant that Interactive Investor has always been tech-focused and mindful of the future of wealth management. 

Interactive Investor Services Limited, a wholly-owned subsidiary of Interactive Investor, is authorised and regulated by the Financial Conduct Authority. The register of the FCA states that as a firm with permission to handle client money; ‘This firm must protect the money it holds and/or controls on behalf of customers. It cannot lend this money or use it to finance its own business.’

This refers to ‘ringfencing’, the concept of separating the assets of clients from the assets used to operate the business activities. This process helps to ensure that in the event of bankruptcy, client assets should remain intact and available for outward transfer to another stockbroker after fees.

As a client of a fully regulated FCA broker, you would also be entitled to up to £85,000 in compensation from the Financial Services Compensation Scheme were you to lose money directly as the result of the failure of the firm.   

At the time of writing, Interactive Investor is set to be acquired by Abrdn, a modern asset management stalwart that oversees £465 billion of assets. This transaction will provide further peace of mind to clients that Interactive Investor is a sustainably-run organisation that will be around for the long term. 

Interactive Investor has recently refreshed the account types and pricing plans available for UK investors. With a simpler range and more features packed in each account plan, choosing the ideal account for you has never been easier. 

The account types available are:

• General investment account
• Stocks & Shares ISA
• Junior ISA
• Self-Invested Pension

All of the accounts have a similar range of investment options available, such as domestic and international equities, funds and bonds.

With the exception of the Self-Invested Pension (also known as a SIPP), you can open one of each account type without attracting any additional fees. That’s because your charges are paid as a subscription plan based on your trading activity across all of your accounts, rather than on a ‘per account basis’. More details on pricing will follow in our ‘Fees and costs’ section.

Interactive Investor does not offer a cash ISA or Lifetime ISA option, unlike some large UK competitors such as AJ Bell [See our full AJ Bell review for more information]

Finally, the broker offers joint accounts and corporate accounts for more complex ownership scenarios. If you’d like to jointly own a portfolio of shares with your spouse, or better utilise company cash then you may want to consider one of these specialist options.

Charges for these accounts are entirely separate because they are not operated by a single individual.

An Interactive Investor account may be opened with as little as £1, or via the setting up of a regular direct debit from your bank account for £25 per month. 

Once opened, you can invest as little as £25 a time with your account.

This low deposit minimum makes the Interactive Investor accounts one of the easiest to open, however, it’s worth remembering that the minimum account fee of £9.99 per month would make it unaffordable to manage a portfolio of less than £1,000.

A demo account is not currently offered by Interactive Investor. This is not necessary because all the relevant information about platform fees charges and investment options is publicly visible on their website.

This allows potential clients to make their decision to open an account with confidence using all the information readily available. 

Interactive Investor offers trading in an impressive range of publicly traded stocks & shares from around the world. In fact, they claim to offer the widest range of international shares. 

That’s because Interactive Investor is a member broker that can directly place trades on many global stock exchanges. This allows them to provide wide access to these markets to their own clients. 

Many other retail investment brokers actually rely on third parties for access to the stock market. This naturally leads to restrictions on what they can and cannot offer their clients. 

If you consider that the UK’s stock market only represents approximately 4% of the value of the world’s listed companies, you will begin to appreciate why it’s so important for you to have easy access to US and other international businesses.

Interactive Investor offers hundreds of funds for investors to purchase. It does an excellent job in narrowing down this vast list into its Super 60 Investments shortlist of funds, designed to cover a variety of best-in-class funds in a variety of asset classes. II also publishes a shortlist of ethical funds called ‘Ace 40’ for investors who want to only put their money to work in companies that are creating positive impacts on the environment and civil society.

Interactive Investor provides access to high-risk investments that are not widely available on most investment platforms. These include Venture Capital Trusts and direct investment in fixed-income investments such as corporate bonds. 

These investments are labelled as ‘high risk’ because:

• You may be ‘locked into’ the investment for an indefinite period rather than being able to sell on the open market at a time of your choosing
• The underlying investment strategy of the fund could be high risk and therefore carry a reasonable risk of high losses
• The market for the resale of such investments may be small, and therefore may not be ‘liquid’ enough to guarantee a fair offer price at all times for your investment. 

While these investments may be unsuitable for many investors, their presence on the menu of investment options helps to build up Interactive Investor’s brand as a one-stop shop for private investors. 

Interactive Investor calculates your account and dealing fees based upon the ‘plan’ you pick. 

There are two core plans; a £9.99 per month ‘Investor’ plan with great value features, and a £19.99 per month ‘Super Investor’ plan that contains additional perks and discounts.

Because these fees are capped, they represent a bargain for investors with large pots. 

On a portfolio of £100,000, even the Super Investor plan equates to less than 0.3% per year. The more you deposit, the smaller the fee will become as a % of your holdings. It’s difficult to find a broker charging less for this range of financial services.

Below, we’ll list what you’ll receive for each plan to allow you to compare the offering against the price: 

£9.99 Investor plan

• 1 free monthly trade
• Online trading fees:
  • UK shares and funds, US Shares: £7.99
  • Other International Shares: £19.99
  • Free regular investing
  • Dividend reinvestment: £0.99

£19.99 Super Investor plan

• 2 free monthly trades
• Allows 5 friends & family to set up accounts for no monthly account fee
• Online trading fees:
  • UK shares and funds, US Shares: £3.99
  • Other international shares: £9.99
  • Free regular investing
  • Dividend reinvestment: £0.99

Investors who aim to keep their portfolio simple with one or two funds will love the no-frills Investor plan, which comes with one free trade each month. Savvy fund investors may limit the number of transactions to use these free trades efficiently and avoid paying any dealing charges altogether. 

The Super Investor plan costs £10 more each month but comes with a host of benefits such as bargain trading fees of £3.99 for US shares, and the option to enable friends and family to invest with zero account fees.

We conclude that the Super Investor account is a great deal for the head of a financially-savvy family or investors who want to deal regularly to manage a portfolio of UK & US company shares. 

The UK & US share dealing fees specified above of £7.99 and £3.99 are comparable to other UK stockbrokers. But we suggest you pay close attention to the offer of free regular investing, which is available with both account plans.

Regular investing is where Interactive Investor will place pre-ordered trades on a fixed day each month on behalf of all investors. This allows the broker to group together similar orders and save on its own costs at the exchange. 

Interactive Investor’s free regular investing offer means that you could invest in a wide variety of instruments without paying a penny in transaction fees. This is a market-leading offer, as most other UK stockbrokers charge between £1.50 and £5 for this service. 

Interactive Investor charges an incremental account fee of £12.99 per month if you add a Self-Invested Pension. 

It also levies foreign exchange fees (1.5% maximum) when converting your own currency into foreign currency. II allows you to manage your foreign exchange fees better than other stockbrokers by allowing you to hold 9 currencies in cash at any time. This may allow you to sell US shares and use the US Dollar proceeds to buy other US shares without needing to convert between currencies.

Urgent UK withdrawals attract a fee of £15, but withdrawals are free if you can wait 1-2 working days for the transfer to process.

Interactive Investor currently offers no interest rate paid on cash balances held in your account. This isn’t a fee, but represents an opportunity cost if you could have earned a return on that cash if it was deposited elsewhere.

Trading by telephone costs £49 in addition to the basic dealing charge for the trade.
