Interactive Brokers UK Review
Your capital is at risk.
Interactive Brokers, or IBKR, is a major international investment broker that mostly targets sophisticated investors and active traders. Range of investments is one of its main strengths. Beyond shares, funds, and bonds in more than 90 markets, you can trade options, futures, and CFDs. Its options trading is one of the main reasons people choose IBKR over other investment platforms.
IBKR is strongest for active traders making large trades in international markets, as the FX fee is very competitive and the mobile app is very good. The platform is complex, and pricing is confusing because the commission depends on the market. It's not aimed at beginners or people investing small amounts, and I would say it's not really for long-term buy-and-hold investors. The stocks and shares ISA carries a £3 monthly minimum activity fee, which you pay in months you don't trade and is waived when you do trade by paying at least the same amount in commissions.

Pros and cons
PROS
- More than 70,000 stocks and 19,000 ETFs in over 90 markets.
- Options, futures, and CFDs alongside shares, funds, and bonds.
- Low 0.03% fee on automatic currency conversion.
- The mobile app can plot stocks, indices, and even crypto on one chart.
CONS
- £3 monthly minimum activity fee on the stocks and shares ISA.
- Complex for beginners, with about 100 order types and confusing pricing.
- No fractional shares or dividend reinvestment inside the ISA.
My top takeaways for Interactive Brokers in 2026:
- Interactive Brokers charges no platform fee on its general investment account, and 20,000 of its funds carry no transaction fee.
- IBKR charges £3 a trade on U.K. shares and ETFs up to £6,000 and 0.05% of the trade value above that, so a £10,000 trade costs £5.
- IBKR's 0.03% currency conversion fee compares with as much as 1% at some other platforms.
- The Interactive Brokers stocks and shares ISA has a £3 monthly minimum activity fee, which adds up to £36 a year if you never trade.
- IBKR pays interest only on uninvested cash above £8,000, at 3.227% on GBP balances for accounts worth more than £100,000 and a blended rate of up to 3.13% for smaller accounts.
Interactive Brokers UK fees
IBKR has no minimum deposit, and its low FX fee can be appealing for international traders. However, the many different commission structures depending on the market you're trading in make the broker less suitable for beginners or small investors in the U.K., and the ISA's monthly minimum is one reason why.
Platform fees: The general investment account has no platform fee and no inactivity fee, whatever your balance, so IBKR can be a good way to hold mutual funds at low cost. Not many other platforms offer mutual funds without platform costs, and Trading 212 doesn't have mutual funds at all. The ISA is different. Its monthly minimum activity fee of £3 means you'll pay at least £36 a year in fees or commission, if you don't trade during that time. The fee is waived if you pay at least that much in commissions in the months you do trade.
Dealing charges: Commissions start from £3 per trade for U.K. shares, ETFs, and investment trusts, and from €3 for most European stocks. If you make a trade over £6,000, the flat £3 fee changes to a commission of 0.05%, which means a fee of £5 on a £10,000 trade. Frequent traders get no discount. A U.K. share deal under £6,000 costs £3 whether it's your first of the month or your 20th. U.S. shares cost $0.005 per share, with a minimum $1 trade fee. Placing a trade by phone costs $30.
Funds and bonds: Thousands of U.S. mutual funds are among the 20,000 funds you can trade with no transaction fee. Other funds have a dealing fee of £4.95 or €4.95 per trade. Corporate bonds and gilts cost 0.1% on the first £10,000 of trade value, falling to 0.025% on amounts above that.
Currency conversion: One of IBKR's main selling points is its low FX fee. IBKR charges 0.03% above the exchange rate for an automatic conversion, which is very competitive compared with other platforms, some of which can charge as much as 1%.
Interest on cash: IBKR doesn't pay interest on the first £8,000 or $10,000 of uninvested cash, or the equivalent in other currencies. Clients with a net asset value of more than £100,000 earn an annual rate of 3.227% on GBP cash above £8,000, or 3.13% on USD cash above $10,000. Below £100,000, the rate is blended, up to a maximum of 3.13%. As an example, on a cash balance of £10,000 and a net asset value of £20,000, the interest on £2,000 would be 0.88%. That's an overall blended rate of 0.18% on the full £10,000.
Withdrawals: The minimum withdrawal is £1. ISA withdrawals are free up to two a month and cost £7 each after that.

Range of investments
I would say active day traders and experienced investors looking to invest in a wide range of assets and instruments get the most from IBKR. It lists more than 70,000 stocks, 19,000 ETFs, and 55,000 mutual funds. That's more than 144,000 investments, and investment trusts are available too. The stock count is higher than that of many other investment platforms in the U.K., and trades are available in more than 90 markets.
Interactive Brokers is well known for its investment choices beyond the typical stocks and shares, and users always rank it highly for options trading. Futures and CFDs are available as well. So is an extensive range of global bonds and gilts, and you can trade crypto.
Fractional shares: Fractional trades are available on more than 10,500 stocks, which IBKR says is more than any other platform. Outside the stocks and shares ISA, you can invest in major stocks with as little as £1 or $1, which is great for newer investors looking to invest small amounts of money.
Crypto trading: Interactive Brokers offers the opportunity to invest in crypto, by either buying it directly or by investing in crypto ETNs, which the FCA now allows U.K. investors to access. Fees for crypto are 0.12% to 0.18% of trade value (with a minimum commission of $1.75) with no added spreads, markups or custody fees, which makes IBKR competitive on price compared to other platforms offering crypto. Cryptocurrency is not covered by the Financial Services Compensation Scheme (FSCS) in the U.K. and should be viewed as a high-risk investment.
What's missing: There are no ready-made diversified portfolios for investors in the U.K., no advice service, and no spread betting. The lack of ready-made portfolios is a downside for new investors and for anyone who wants to take a long-term, hands-off approach.

Interactive Brokers SIPP
You can't open a SIPP with IBKR directly. Instead you go through one of IBKR's pre-approved SIPP administrators, which must be a U.K. SIPP provider registered with the Financial Conduct Authority. Currently IBKR lists two on its website. The administrator opens a sub-account under its own master account with IBKR, and only one person can trade it.
The entry requirements are strict. You must be a U.K. resident aged 18 to 75, with good or extensive knowledge of the products you plan to trade and at least 100 previous trades of any kind. The SIPP sub-account needs a minimum deposit of $5,000 or the equivalent in stock, and it's a cash account only, with no margin. IBKR charges a $10 monthly minimum brokerage fee, plus market data fees where required. Each administrator sets its own costs on top. You'd likely not want IBKR for your SIPP when so many other platforms offer them directly.

Interactive Brokers UK ISA review
IBKR has a stocks and shares ISA but no cash ISA. One benefit of the IBKR ISA is that if you're looking to invest in global stocks, it lets you invest in companies based in a broader range of countries than other ISA investment providers. Those include Hong Kong, South Korea, Canada, Mexico, and Japan, alongside the usual U.S. and U.K. exchanges. There's a broader range of European markets too, such as Lithuania and Spain.
Interactive Brokers stocks and shares ISA
In the IBKR ISA you can hold shares, ETFs, mutual funds, investment trusts, and bonds. There are no ready-made portfolios inside it.
The £3 minimum: There's a monthly minimum activity fee of £3 for the IBKR ISA. Typically you'll pay trading fees, and if you don't trade you'll still pay the minimum monthly fee. Commission counts towards it. If you generate £2 of commission in a month, you're charged the remaining £1, and if you generate £3 or more across linked IBKR accounts, there's no fee. One U.K. share trade a month would cover it. Considering there are many free ISA providers out there, I can't see why you'd pick IBKR over another broker due to the possible monthly fee unless you are an active trader or prefer access to a wider range of global markets.
Restrictions: Dividend reinvestment is not allowed in the ISA, which does seem odd to me. Elsewhere on IBKR you can buy fractions of more than 10,500 stocks from £1. Fractional share trading is not permitted in the ISA, which is again a barrier for beginners and anyone investing small amounts.
ISA flexibility and transfers
The stocks and shares ISA is not flexible. You get two free withdrawals a month from it, and any further withdrawal in the same month costs £7.
Interactive Brokers accepts ISA transfers in, and there are no charges for transferring. However, IBKR doesn't support partial transfers. Only full account transfer requests can be made. With no cash ISA on the platform, there's also no option to move money between a cash ISA and a stocks and shares ISA at IBKR.
Interactive Brokers Junior ISA
IBKR has a Junior ISA, with a lower £1 minimum monthly activity fee minus commissions. As with the adult stocks and shares ISA, you can invest in ETFs, stocks, mutual funds, and bonds. Transfers in are accepted. IBKR doesn't have a Junior SIPP.
Mobile trading apps
For active traders, the mobile app is very good. IBKR's apps run on iPhone and Android, and there are two of them, IBKR Mobile and a slimmed-down alternative called IBKR GlobalTrader. I mostly used IBKR Mobile. The charting is the strongest part of it. The overall appearance is cluttered and does feel confusing, and options are very heavily promoted on the home screen.
Placing a trade: The order ticket is easy enough to find by tapping 'Buy' on an individual stock or investment. The default order type is set to 'Limit', so you have to use the drop-down menu to switch to market price. This has the potential to confuse beginners who may not understand what this means or which order type they should pick. IBKR in fact has about 100 different order types, some of which are extremely complex algorithmic or very niche order types. The three most common are market, limit, and stop. For those starting out, IBKR Campus Traders' Academy has a video that walks you through the different order types.
Charting: You can compare different companies, indices, and even crypto on the same chart, which is pretty cool and not something I've seen offered on other investing apps we review. The chart tools on IBKR Mobile are extensive. Tap full screen to get the full set of drawing tools and indicators. You can also save an indicator template. TradingView charts aren't available in the app, as far as I can see. IBKR lists 155 indicators and 85 drawing tools across its charting, and its charts can display corporate events and hold your notes.

IBKR Mobile plotted McDonald's, Bitcoin, and Barclays on one chart, switching the scale to percentage change so the three can be compared directly. Over the period shown, Barclays gained 18.88% and Bitcoin 14.34%, and McDonald's lost 19.53%. The D markers along the bottom flag McDonald's dividend dates, one of the corporate events the charts can show.
Portfolio and alerts: Tap the portfolio tab at the bottom of the app to see your overall positions and portfolio value. Total returns appear at the top, along with today's performance. You can set price, trade, and margin alerts in IBKR Mobile, with notifications sent to your email address or as a text message. Push notifications aren't available inside the app.
Elizabeth's take
"The IBKR Mobile app is very comprehensive, but the overall appearance is cluttered and does feel confusing. Certainly not aimed at beginners. The GlobalTrader app is more slimmed down and easier to find your way around, but still offers good tools."
Elizabeth Anderson
Lead Writer for the UK
IBKR GlobalTrader: The GlobalTrader app is easier to find your way around than IBKR Mobile, and it still has good tools. I'd recommend this app for brand new and everyday investors, particularly because the order ticket provides plentiful contextual education around different order types and market mechanics when making trades.

IBKR GlobalTrader's order ticket explains each order type as you build the trade, shown here on a market order for nine Tesla shares. The note warns that a market order has no price protection and may fill well above the displayed ask.
Trading platforms
You can trade in real time on the IBKR website, which is aimed at experienced investors. IBKR's live pricing is very strong, with its smart routing technology searching for the best available price at the time of executing an order. The website is also home to PortfolioAnalyst. That tool shows far more about your holdings than the portfolio tab in the app.
Web charting: The web charting tools are very extensive, even on the free demo account. One great thing is that, as in the app, you can overlay indices as well as stocks on the same chart, which not many platforms offer.

The IBKR website can overlay an index on a share chart, shown here with Apple against the Nasdaq-100 over one year. On a percentage scale, Apple was up 19.73% and the index 16.15%.
PortfolioAnalyst: This website tool shows your overall portfolio performance over a specific timeframe. It also tracks the change in net asset value, deposits and withdrawals, top and bottom movers, and recent activity. A pie chart shows the sectors of your holdings, and you can add other sections, such as an ESG rating.

PortfolioAnalyst on the IBKR website opens on a dashboard of widgets, here set to one year of monthly performance on a demo account. The Change in NAV panel shows a 3.24% return for the period, alongside deposits and withdrawals.
AI tools: Interactive Brokers has recently started rolling out AI integration. You can now connect your account to ChatGPT, Claude, or other AI tools to help you research investment decisions and analyse your portfolio. These AI platforms can't trade on your behalf automatically. However they can send draft orders to your account that must be approved manually under a new tab labeled "AI Instructions" on IBKR Mobile or IBKR Desktop.
Desktop platforms: IBKR's two desktop platforms are IBKR Desktop and Trader Workstation, known as TWS. IBKR also offers access to advanced TradingView charts through its platforms. If you have a separate TradingView account, you can integrate it with IBKR to see positions held with IBKR, as well as orders and balances. IBKR Desktop is aimed at active traders wishing to update to a more modern tech stack compared to TWS. My view is that it's simpler and easier to use than TWS, and it's designed to be more accessible for beginners and people new to IBKR.
Demo account: You're given £1 million of paper money in IBKR's demo account to do practice trades with before using any of your own real money. It's advised for beginners. The platform can feel overwhelming if you don't have previous trading experience, so taking the time to learn the platform and make a few test trades is highly recommended.

Research
Interactive Brokers has in-depth research materials across shares, funds, ETFs, and bonds, including Morningstar ratings and fund research reports. There's extensive Morningstar data available for free, including analyst insights and equity and fund research material, but if you want even deeper insights there's a cost of $15 a month.
Stock screener: IBKR's stock screener is extremely detailed. If you're an experienced trader looking for specific companies that meet exact criteria, it compares very well with what other platforms have. IBKR says it has leaned into AI for its screener recently. You can describe what you're looking for, such as 'defence stocks with a net profit margin greater than 12%' or 'rank stocks with high dividends', rather than having to fiddle around with drop-down menus. That's only available on desktop, not the mobile app. When I tested the website on a demo account, I couldn't find the AI screening tool.
Fund and bond screeners: IBKR's in-depth market screeners cover funds and bonds as well as shares. There's an ETF screener and a mutual fund screener too, which matters on a platform with 55,000 mutual funds to choose from.
Investment themes: The 'investment theme' section on the website is also very in-depth. You can sort companies and funds from A to Z by investment theme, such as firms and funds involved in battery recycling or cloud computing.
Real-time data and alerts: Real-time market data is available on the website and app. Price alerts and news are available and customisable, and you can tailor the news to your portfolio or watchlists.
Education
Education is a real strength of Interactive Brokers. IBKR is aimed at traders, not everyday investors, so if you're considering it, I'd watch some of the video guides first and use the demo account. Most of the material is on IBKR Campus, with podcasts, webinars, videos, and written articles. Free courses on different products and markets are also available to students and traders of all skills and experience. Topics cover share trading, funds, and retirement.
Videos: IBKR's YouTube channel has more than 1,500 videos, and many are also hosted on its website. They include how to use charts on IBKR, getting started on the mobile app, and an introduction to options and different order types. These videos are very helpful, as IBKR is complex.
Webinars: IBKR has a good variety of webinars, covering topics such as investing in gold and the role of thematic ETFs in portfolios, which is unusual compared with other brokers. They're provided by third parties, typically fund managers, but you register through IBKR. Past webinars are archived.
Customer support: Support runs 24/7, and current customers can contact IBKR by phone, live chat, or email. Prospective customers can phone. Live chat is only open to existing customers.

Interactive Brokers is for traders looking for an institutional-grade platform. It's our top pick for investment choices, and the range earns it. You can trade in more than 90 markets, with options, futures, and 55,000 mutual funds available alongside shares. Live pricing is very strong, and the FX fee is just 0.03%.
The tools are strong as well. The mobile charting is extensive, the website has PortfolioAnalyst for tracking performance, and more than 1,500 educational videos help you get to grips with it all.
I think it would feel very overwhelming to beginner investors. Pricing is confusing too. U.K. shares start at £3 a trade and U.S. shares at $0.005 a share, and there's a £3 monthly minimum on the ISA. For a small ISA, I can't see the case for paying that when many providers charge nothing. There's no direct SIPP either.
If you're a day trader or an experienced investor who wants a wide range of global assets, I'd point you to IBKR. If you're a beginner or a buy-and-hold investor with a small pot, I'd look elsewhere.
