About Interactive Investor

Interactive Investor was founded in 1995 in Manchester, making it the second-oldest online broker in the UK. In 2022, it was acquired by abrdn (formerly Standard Life Aberdeen), one of the UK's largest asset management groups. The acquisition added significant financial backing and institutional credibility.

Today, ii serves more than 400,000 clients and holds approximately 65 billion GBP in client assets. The platform operates exclusively in the UK and is available only in English. Its offices are located in Manchester, London, and Glasgow.

What sets ii apart in a crowded UK broker market is its flat-fee subscription model. Instead of percentage-based platform fees that compound as your portfolio grows, you pay a fixed monthly charge regardless of your portfolio size. This is particularly attractive for investors with portfolios above 50,000 GBP, where a percentage-based fee would become significantly more expensive.

ii has received recognition from respected UK financial publications, including Best Online Broker from Investors Chronicle and Best SIPP from Boring Money.

Regulation and Fund Security

Interactive Investor Services Limited is authorised and regulated by the Financial Conduct Authority (FCA) under firm reference number 141282. The FCA is one of the most rigorous financial regulators in the world, making this a strong regulatory credential.

Client funds are held in segregated accounts, meaning your money is kept separate from the firm's own capital. In the event of firm insolvency, segregation provides a meaningful layer of protection.

UK investors also benefit from Financial Services Compensation Scheme (FSCS) coverage of up to 85,000 GBP per eligible person. This is among the most generous retail investor protection schemes in any jurisdiction.

It is worth noting that Interactive Investor does not offer negative balance protection, which is relevant context even though it does not offer leveraged products. There are no CFDs or margin trading products, so this limitation has no practical impact for the typical ii client.

Is Interactive Investor safe? Given FCA regulation, FSCS protection, fund segregation, and its backing by a listed asset management group, the answer is firmly yes for UK retail investors.

Trading Conditions and Account Types

Pricing Model

Interactive Investor does not charge spreads or percentage-based commissions. Instead, you pay a fixed monthly subscription fee and a flat 3.99 GBP per trade for any order that is not covered by your plan's free trade allocation. Regular investing (automated monthly purchases) is free across all plans.

This model is unusual in the UK market and requires careful evaluation based on your trading frequency and portfolio size.

Account Plans

All plans carry a minimum deposit of 0 GBP, meaning there is no barrier to opening an account.

Account Wrappers Available

ii supports multiple tax-efficient account structures, which is one of the platform's genuine strengths:

• Stocks and Shares ISA
• Self-Invested Personal Pension (SIPP)
• Lifetime ISA (LISA)
• Junior ISA (JISA)
• General Trading Account

The Pension Builder plan is specifically designed for SIPP holders. The Super Investor plan bundles ISA and JISA access, making it suitable for families managing multiple accounts under one subscription.

Who Benefits Most from the Flat-Fee Model?

The maths matter here. If your portfolio is under 10,000 GBP and you trade infrequently, a platform charging 0.25% per year with no monthly fee may cost you less. As your portfolio grows past 50,000 GBP, the fixed fee becomes increasingly cost-effective compared to percentage-based platforms.

Interactive Investor does not offer CFDs, forex, leverage, crypto, options, or futures. If you are looking for any of those instruments, ii is not the right platform.

Trading Platforms

Interactive Investor provides a browser-based web platform and a dedicated mobile app. There is no downloadable desktop application.

The web platform is clean and functional. Navigation is straightforward, and the account management tools — including ISA allowance tracking and portfolio analytics — are well integrated. It is built for long-term investors rather than active traders, and the interface reflects that philosophy.

The mobile app covers the essentials: order placement, portfolio monitoring, and access to research. It is not designed for high-frequency trading, which is consistent with ii's broader positioning.

Research and tools included:

• Super 60: analyst-curated selection of recommended funds across major asset classes
• Quick-start funds: simplified fund selection for newer investors
• ii Insight: in-house research articles and market commentary
• Stock screener: filter equities by sector, market cap, and other criteria

The Super 60 list is a genuine differentiator for investors who want research-backed guidance without paying for a financial adviser.

Tradable Instruments

Interactive Investor offers a broad range of real assets. This is an investment platform, not a leveraged trading venue.

The execution model accesses major global exchanges directly: LSE, NYSE, NASDAQ, Xetra, Euronext, ASX, and TSE. There is no leverage. Minimum order size is 1 share.

One notable gap is the absence of fractional shares. You must purchase whole shares, which can be a limiting factor when investing in high-priced US stocks.

Deposits and Withdrawals

Deposits and withdrawals are free. There are no inactivity fees. The minimum deposit is 0 GBP. Withdrawals are processed via bank transfer within 1-3 business days.

The absence of e-wallet options (Skrill, PayPal, etc.) is consistent with ii's positioning as a traditional UK investment platform rather than a trading app.

Customer Support and Education

Support

Support is available in English only. The hours are reasonable for UK market participants. There is no 24/7 support, which may be a limitation if you hold international positions outside UK trading hours.

Education

Interactive Investor provides a meaningful educational offering:

• Webinars: regular investor events and market briefings
• Videos: tutorials and market updates
• eBooks: downloadable investment guides
• ii Insight: ongoing research and commentary
• Super 60 and Quick-start funds: curated guidance for less experienced investors

A demo account is not available. This is a common limitation among UK investment platforms targeting long-term investors rather than active traders. If you want to practice before committing capital, ii does not offer that option.

FAQ

Is Interactive Investor regulated? Yes. Interactive Investor Services Limited is authorised by the FCA under firm reference number 141282. Client assets are covered by the FSCS up to 85,000 GBP.

What is the minimum deposit at Interactive Investor? There is no minimum deposit. You can open an account with any amount.

How much does Interactive Investor cost per month? Plans start at 4.99 GBP per month (Essentials) and go up to 19.99 GBP per month (Super Investor). Each additional trade costs 3.99 GBP beyond your plan's free allocation.

Does Interactive Investor offer CFDs or forex? No. ii is a pure investment platform offering equities, funds, ETFs, bonds, and investment trusts. There are no leveraged products.

Can I open an ISA or SIPP with Interactive Investor? Yes. ii supports Stocks and Shares ISA, SIPP, Lifetime ISA, Junior ISA, and a standard trading account within a single subscription.

Is Interactive Investor suitable for beginners? The Super 60 and Quick-start funds make ii accessible for newer investors. However, the lack of a demo account and the monthly fee structure may not suit complete beginners with small initial capital.

Does Interactive Investor offer fractional shares? No. You must purchase whole shares. This limits access to high-priced US stocks for investors with smaller budgets.

Verdict

Interactive Investor occupies a well-defined niche in the UK investment market. Its flat-fee model is genuinely differentiated and represents strong value for investors with sizeable portfolios. If you hold more than 50,000 GBP in investments, the fixed monthly cost compares favourably to the percentage-based fees charged by many competitors.

The regulatory credentials are excellent. FCA authorisation, FSCS protection up to 85,000 GBP, fund segregation, and the backing of abrdn make this one of the more secure platforms available to UK investors.

Where ii falls short is scope and flexibility. It is not designed for active traders, and it offers none of the leveraged or speculative instruments available elsewhere. The absence of fractional shares is a practical limitation. The monthly fee also makes it a poor fit for investors with small balances who trade infrequently.

Reviewed Interactive Investor 2026 summary: a reliable, well-regulated UK investment platform best suited to investors with larger portfolios seeking a straightforward, cost-capped approach to long-term investing.
