Fees and Trading Costs in 2025
Despite being one of the lowest-cost brokerage providers, Interactive Investor still has several fees that investors must consider in 2025. Most of these fees are transparent, but a few can slip under the radar.
Interactive Investor Subscription Plans

Platform and App Experience in 2025
II’s investment platform strikes a delicate balance between simplicity and control. On the web-based management dashboard, you can quickly gain a clear overview of all your holdings, portfolio performance, and cash balances.
The functional layout can appear to be a bit dated compared to other modernised trading platforms. But it’s very easy to see exactly what’s going on, tracking trade credits, viewing upcoming subscription payments, and checking individual share performance over time.
Similarly, the mobile app is quite intuitive and includes plenty of essential tools. This includes price alerts, personalised watchlists, and a market news feed. The latter, in particular, is handy for investors seeking new ideas from experts in the form of articles, videos, and podcasts. Altogether, the quality and ease-of-use of the mobile reflected in the glowing user reviews with a 4.5 out of 5 on the Google Play store, and a 4.6 on the Apple App Store.
Both the web platform and the II mobile app provide access to the Knowledge Centre, helping novice investors get past all the jargon and learn how to build wealth more efficiently.
The support for beginners is only compounded by the curated lists of starter investments through the platforms Quick-Start Funds and Super 60 shortlist. And should you run into any trouble relating to investing or your account, there is a handy UK-based call centre available throughout the work week.
Is An Interactive Investor Share Dealing Account Right For You?
The Interactive Investor Stocks and Shares ISA has a lot to offer, especially for long-term focused investors with larger portfolios. It provides a simple yet effective trading solution with expert-curated investment ideas. Although the interface may appear dated, it makes up for it in terms of ease of use and functionality.
However, even with its cheaper Investor Essentials subscription plan, the service is not the cheapest offering compared to others for smaller investors. It also lacks advanced trading tools that expert traders rely upon for options and hedging strategies.
Therefore, the Interactive Investor Stocks and Shares ISA could be a great fit for wealthier long-term investors who are mindful of costs. The larger a portfolio grows, the greater the benefit of these cost savings. But for short-term traders, it’s likely worth exploring other investment accounts.
Good for long-term, cost-conscious investors who want lots of flexibility
