How we ranked fees
We categorized Interactive Investor’s costs as low, medium, or high by benchmarking them against the fees charged by all other brokers we have reviewed.
Before diving into the details, it’s useful to clarify the main types of brokerage costs. The two key categories to consider are trading-related fees and non-trading charges.
Trading fees apply when you place trades and may include items such as commissions, bid-ask spreads, financing costs, and currency conversion fees. Non-trading fees, on the other hand, are not directly linked to trading activity and can cover expenses like withdrawal charges or inactivity penalties.
In the sections that follow, we outline the most important fees Interactive Investor applies across different asset classes. For instance, when investing in shares, commission costs are typically the most relevant factor.
We also benchmarked Interactive Investor’s pricing against two comparable platforms, AJ Bell Youinvest and Hargreaves Lansdown. These peers were selected using objective criteria such as the range of products offered, typical client profiles, and overall pricing structures. A more in-depth comparison of alternatives to Interactive Investor is available separately.

Interactive Investor Trading Costs Overview
Interactive Investor’s trading charges fall into the mid-range compared with other brokers.
Clients can select from three different pricing plans, each varying in monthly subscription costs and transaction fees for specific instruments. Under the Investor plan, account holders receive one free trade per month, while the Super Investor plan includes two complimentary trades. The Pension Builder plan does not include any free trades by default, unless the plan is upgraded.
The Pension Builder option is designed as a straightforward Self-Invested Personal Pension (SIPP). For an additional monthly charge, it can be enhanced to include an ISA, a standard trading account, unlimited Junior ISAs for each child, and one free trade per month.
Subscribers to the Super Investor plan also gain complimentary access to Interactive Investor’s Friends and Family scheme, which allows them to gift up to five Investor plan memberships at no extra cost.
In addition, no commission is charged on regular monthly investments made through the platform’s recurring investment feature. This benefit applies across all plans, with a minimum investment amount of £25 per transaction. Each account can support up to 25 scheduled monthly investments, covering eligible assets such as funds, widely traded shares, ETFs, and investment trusts.
For UK-based clients, Interactive Investor offers both ISA and SIPP accounts. SIPP access is provided through the Pension Builder plan, which is priced at £12.99 per month.
