Choosing the right broker is one of the most important decisions for any investor. Over the past few years, I have personally used Interactive Brokers (IBKR) for both stock and ETF investing, including global markets, and my experience has been eye-opening. In this review, I’ll share my first-hand experiences, covering everything from account setup to trading platforms, fees, research tools, customer service, and overall usability. My goal is to give UK investors a realistic, experience-based perspective on whether Interactive Brokers is a good fit for their investing goals.

Account Setup and Registration
Opening an account with Interactive Brokers was straightforward but slightly more involved than modern fintech platforms like Trading 212. IBKR offers several account types, including:
-
Individual Cash Account – Standard brokerage account for UK residents.
-
Margin Account – Allows leveraged trading.
-
ISA and SIPP Accounts – For UK tax-efficient investing.
The registration process required submitting proof of identity, proof of address, and answering questions about investment experience. The verification process took about 1–2 business days, which was faster than expected for an international broker.
Funding my account was simple. I could deposit GBP via UK bank transfer or USD via international transfer. IBKR also supports multi-currency accounts, which I found extremely useful for trading US and European stocks without paying unnecessary conversion fees every time.
Platform Experience: Trader Workstation and WebTrader
Interactive Brokers is known for its powerful trading platforms, and my experience confirmed this. IBKR offers multiple platforms:
-
Trader Workstation (TWS): Desktop platform with extensive charting, analytics, and trading tools. Ideal for experienced traders.
-
IBKR WebTrader: Browser-based platform for simpler trading and account management.
-
Mobile App: Convenient for monitoring positions on the go.
My Experience:
-
TWS: Initially overwhelming, but once I learned the layout, it became a powerful tool for analysing market trends and managing trades. Features like advanced order types, conditional orders, and market scanners are unmatched.
-
WebTrader: Clean and intuitive, perfect for placing trades quickly without the complexity of TWS.
-
Mobile App: Smooth and responsive, making it easy to check portfolios and execute trades when I was away from my desk.
Overall, the platform experience is best suited for intermediate to advanced investors. Beginners may find it daunting at first, but the power and flexibility are excellent once you familiarise yourself with the interface.
Trading Stocks and ETFs
I primarily used IBKR for long-term investing in global stocks and ETFs, and my experience was very positive.
Stocks and ETFs
-
US Stocks: Access to major exchanges such as NYSE and NASDAQ. Execution is fast, and I appreciated the multi-currency functionality, which saved money on currency conversion.
-
UK Stocks: Easy access to LSE-listed equities and ETFs.
-
ETFs: Full access to global ETFs, including Vanguard, iShares, and SPDR products. Fractional shares are supported for many US securities, which is excellent for small investors.
Order Execution
-
Trades execute quickly, and spreads are competitive.
-
I found direct market access particularly useful when trading large or volatile stocks.
-
Conditional orders and bracket orders helped me manage risk effectively, something I couldn’t do on simpler platforms.
Interactive Brokers is ideal for investors who want professional-grade execution and global market access. For simple, UK-only ETF investing, it may feel more complex than necessary.
Fees and Costs
IBKR is widely known for low fees, and my experience confirmed this.
-
Stocks and ETFs: Commission varies by market, but generally very low. For example, UK stocks are roughly £1 + 0.08% per trade, and US stocks are $0.005 per share with a minimum of $1.
-
Currency Conversion: I saved money using multi-currency accounts by holding USD and converting only when necessary, avoiding hidden conversion fees charged by some brokers.
-
Inactivity Fees: IBKR no longer charges inactivity fees for accounts over a certain size, which is a relief for part-time investors.
-
Advanced Trading Fees: There are fees for some niche instruments, like options and futures, but these are clearly outlined and competitive.
Overall, IBKR is one of the most cost-effective brokers I’ve used, especially for global trading.
Research and Analytical Tools
One of Interactive Brokers’ standout features is the research and analysis tools.
-
Fundamental Data: Full access to P/E ratios, dividend yields, earnings history, and analyst ratings.
-
Technical Indicators: TWS offers dozens of chart indicators, including moving averages, Bollinger Bands, MACD, and RSI.
-
Screeners and Alerts: I could screen for stocks and ETFs based on sector, market cap, performance, and set price alerts.
-
News Integration: Real-time market news integrated into the platform, including market summaries, analyst reports, and economic indicators.
As someone who likes to research investments thoroughly, I found IBKR’s tools invaluable. Compared to simpler platforms like Trading 212, IBKR’s research capabilities are far superior.
Customer Support
My experience with customer support was mostly positive:
-
Live Chat: Generally responsive, with knowledgeable staff.
-
Email Support: Replies usually within 1 business day.
-
Help Centre: Extensive tutorials, FAQs, and guides for beginners and professionals.
Occasionally, support can take longer during market spikes, but overall, IBKR’s customer service is reliable and informative.
Security and Regulation
As a UK investor, security was very important. IBKR is:
-
FCA-regulated in the UK.
-
SIPC-insured in the US for up to $500,000, including $250,000 cash coverage.
-
Segregated client funds, ensuring my money is separate from the company’s operational accounts.
-
Two-factor authentication is mandatory for withdrawals and recommended for logins.
I felt confident that my investments were safe and secure, particularly important for international trading.
