Our Take On eToro
eToro's social trading platform excels with its outstanding user experience and lively community chat, aiding beginners in spotting opportunities. It offers competitive fees on numerous CFDs and real stocks, alongside exceptional rewards for seasoned strategists.
Tobias Robinson Reviewer
Pros
- In July 2026, eToro Edge introduced significant enhancements, including a charting package tailored for active traders and AI trading via Tori.
- The trading app provides a top-tier social environment featuring an engaging feed and community chat, which we enjoy using.
- The entry requirements for eToro Club have been reduced. For $4.99 monthly, members enjoy 18 benefits, including a debit card that converts purchases into stocks with a 4% share return.
Cons
- The absence of extra charting platforms such as MT4 may deter experienced traders who rely on external software.
- There are no assured stop-loss orders, which could be a valuable risk management tool for novice traders.
- The minimum withdrawal is set at $30, accompanied by a $5 fee. This may impact traders with limited funds, particularly those just starting out.
61% of retail CFD accounts lose money. eToro is a multi-asset investment platform. The value of your investments may go up or down. Your capital is at risk.
Our Take On Plus500
Plus500 provides a seamless experience for traders with its CFD platform, featuring a sleek design and interactive charting. However, its research tools are basic, fees are higher than the most economical brokers, and its educational resources could be improved.
Tobias Robinson Reviewer
Pros
- Plus500 offers a dedicated WebTrader platform tailored specifically for CFD trading. It features a user-friendly and streamlined interface.
- In 2025, Plus500 introduced new share CFDs in emerging sectors such as quantum computing and AI, presenting opportunities in stocks like IonQ, Rigetti, Duolingo, and Carvana.
- The broker provides low-commission trading across varied markets, reducing extra fees and attracting seasoned traders.
Cons
- Plus500's omission of MetaTrader and cTrader charting tools may deter seasoned traders seeking familiar platforms.
- Educational resources are not as extensive as leading brokers such as eToro, which affects beginners' ability to learn quickly.
- The lack of social trading features prevents users from copying trades made by seasoned traders.
81% of retail CFD accounts lose money.
Our Take On Vantage FX
Vantage is an ideal choice for CFD traders looking for a well-regulated broker with access to the dependable MetaTrader platforms. With a swift sign-up process and a minimum deposit of $50, starting trading is simple and fast.
Tobias Robinson Reviewer
Pros
- Vantage upholds a high trust score through its solid reputation, backed by premier regulation from the FCA and ASIC.
- In 2026, the app was enhanced to provide comprehensive asset visibility, consolidating balances from Contract, Copy, and Funding accounts onto a single screen.
- Vantage has enhanced its trading tools for experienced traders, introducing AutoFibo EA to pinpoint potential market reversals.
Cons
- It's unfortunate that some clients must register with the offshore firm, which provides reduced regulatory safeguards.
- To access optimal trading conditions, a substantial deposit of $10,000 is required. This includes a commission of $1.50 per transaction per side.
- Based on tests, average execution speeds of 100ms to 250ms are slower compared to other options.
Our Take On Interactive Brokers
Interactive Brokers ranks highly for seasoned traders due to its robust charting platforms, live data, and bespoke layouts via the new IBKR Desktop app. Its competitive pricing and sophisticated order choices appeal to traders, and its wide equity options are industry-leading.
Tobias Robinson Reviewer
Pros
- IBKR is a highly respected brokerage, regulated by top-tier authorities, ensuring the integrity and security of your trading account.
- Interactive Brokers has introduced a single platform linking prediction markets on Kalshi, CME Group, and ForecastEx. Users can trade yes/no contracts on political, economic, and climate events, with fixed $1 payouts. Enjoy 24/6 market access and earn interest on eligible positions.
- The TWS platform is tailored for intermediate and advanced traders, featuring over 100 order types and a dependable real-time market data feed with exceptional uptime.
Cons
- TWS has a steep learning curve, making it difficult for newcomers to navigate and grasp its features.
- IBKR offers a variety of research tools, but their inconsistent placement across trading platforms and the 'Account Management' webpage creates a confusing experience for users.
- Support can be sluggish and frustrating. Tests reveal that you may face challenges reaching customer service quickly, which could result in delays in issue resolution.
Our Take On XTB
XTB excels for novice traders with its superb xStation platform, minimal trading costs, no required deposit, and outstanding educational resources, many of which are fully integrated into the platform.
William Berg Reviewer
Pros
- In 2026, XTB expanded its asset offerings and markets. It introduced options trading in Spain and Germany, launched spot cryptocurrencies in select regions, and unveiled Investment Plans 2.0. These enhanced plans now feature more pre-built options, including sectors like Defence, a user-friendly interface, and increased flexibility to mix stocks and ETFs within individual plans.
- The xStation platform stands out with its user-friendly design and intuitive tools, such as adaptable news feeds, sentiment heatmaps, and a trader calculator. These features streamline the learning process for new traders.
- XTB offers a superb array of educational resources, such as training videos and articles, embedded within the platform to assist traders of all experience levels.
Cons
- XTB lacks a raw spread account, a feature increasingly offered by competitors such as Pepperstone. This omission might not satisfy traders seeking the most competitive spreads.
- The demo account lasts only four weeks, posing a challenge for traders wanting to fully explore the xStation platform and refine short-term strategies before investing actual money.
- XTB has stopped supporting MT4, restricting traders to its own platform, xStation. This decision may discourage experienced traders accustomed to using the MetaTrader suite.
74% of accounts lose money when trading CFDs with this provider.
Our Take On FXOpen
FXOpen is perfect for high-volume traders, providing swift execution via its ECN system, spreads starting at 0 pips, and reduced commissions as low as $1.50 per lot.
Tobias Robinson Reviewer
Pros
- FXOpen integrated TradingView in 2022 and enhanced its TickTrader platform in 2024. This upgrade delivers Level 2 pricing, over 1,200 trading instruments, and sophisticated order options. The platform appeals to both seasoned and high-frequency traders.
- FXOpen significantly cut FX spreads by over 40% in 2022. In 2023, they launched commission-free index trading. These changes make trading more economical for traders.
- In 2024, FXOpen simplified its account options. Traders now benefit from ECN accounts with raw spreads starting at 0.0 pips. The platform offers rapid execution and reduced commissions for those with high trading volumes, enhancing user experience.
Cons
- Though FXOpen remains a trusted broker with authorizations from the FCA and CySEC, it lost its ASIC license in 2024 due to 'serious concerns.' Consequently, it no longer accepts traders from Australia.
- FXOpen's educational resources are quite limited, with a scarcity of courses and webinars commonly available at brokers such as IG. This deficiency may deter novice traders looking to enhance their understanding.
- Even with an expanded asset portfolio, FXOpen provides a more limited selection of global stocks, commodities, and cryptocurrencies compared to the leading firm BlackBull. This results in fewer diverse trading opportunities for traders.
Our Take On FXPro
FxPro is an excellent choice for traders, offering execution speeds under 8ms, reduced fees from 2022, and superb charting platforms like MT4, MT5, cTrader, and FxPro Edge.
Tobias Robinson Reviewer
Pros
- FxPro uses a 'No Dealing Desk' (NDD) model for swift and transparent order execution, usually within 12 milliseconds, making it well-suited for short-term trading strategies.
- FxPro's Wallet is a notable feature enabling traders to securely manage their funds. It ensures additional protection and ease by separating unused funds from active trading accounts.
- FxPro provides four dependable charting platforms, including the user-friendly FxPro Edge. It features more than 50 indicators, 7 types of charts, and 15 different timeframes.
Cons
- Passive investment options, such as interest on cash or social trading platforms, are limited. While active traders might not notice, competitors like eToro, serving both active and passive investors, provide more comprehensive offerings.
- FxPro offers customer support five days a week around the clock, accessible via various platforms, and the service quality is reliable based on tests. However, the absence of weekend support can be a drawback for traders requiring help beyond standard market times.
- FxPro, with its $10M funded demo account and expanding Knowledge Hub, mainly caters to experienced traders. Beginners might find its account and fee structure challenging to understand.
How Investing.co.uk Chose The Brokers With The Most Clients
We research and frequently monitor the client numbers of important brokers in the UK to maintain an up-to-date list of the most popular firms.
To ensure our data is fresh and accurate, our experts:
- Investigate and review the number of clients of each broker where possible as part of our review process
- Check publicly available data
- Contact brokerage firms directly to verify figures
Why Size Isn’t Everything
The brokers on our list serve huge numbers of clients, but that’s an effect rather than the cause of their success. These firms do so well because they get these fundamental factors right:
Regulation
Most investors prefer to work with a broker that’s overseen by a strong regulatory body like the UK’s Financial Conduct Authority (FCA) and we suggest you to do the same.
The FCA imposes strict conditions on firms to obtain a license, and they require frequent financial submissions to ensure continued compliance.
Clients of FCA-regulated firms can be assured that their funds will be held separately from business accounts and that they will not lose more than their account balance in bad trades, among other protections.
Up to £85,000 of their funds will also be insured against business insolvency in the Financial Services Compensation Scheme.
Track Record
Trading with a broker that has a long and clean track record in the industry provides assurance that your funds are in safe hands.
Another benefit is that established firms have experience in the industry and need to know what traders want in order to stay competitive, so they often provide a more enjoyable trading experience with competitive pricing and attractive features.
Stock Exchange Listing
Choose a broker that’s listed on a major stock exchange and you’ll have the added assurance that this firm runs its business transparently with frequent financial reports.
For example, companies that are listed on the London Stock Exchange must first meet the exchange’s stringent inclusion criteria and then must comply with regulatory rules and undergo monitoring.
Tools & Features
Brokers that serve large customer bases usually have the resources to provide extra tools and features, so you should be able to find a broker that caters to your own investing style.
Some of our favourites include integrated research tools, auto-trading, social trading and sentiment analysis.
I’ve come to appreciate social trading as a very useful feature, especially for newer traders. Apart from the popularity of copy trading, social investing also allows you to read experienced traders’ ideas and to engage in discussions.While it’s important to do your own research and not to blindly trust other people’s analysis, this can be a really useful way to learn about markets and to find out what is trending.
Pros Of Trading With Large Brokers
- Reputation – If someone does a job well, you are more likely to recommend them to a friend. The same goes for trading brokers. Often, a firm’s client base has, to some extent, been built by happy customers recommending the broker to their peers.
- Regulation – Normally, the UK brokers with the most clients are regulated by the FCA from our research. We recommend opting for a regulated brokerage where possible as they generally provide clients with a greater degree of protection than their unregulated counterparts.
- Professionalism – Larger trading brokers tend to have more established processes and ways of interacting with clients. They are more likely to have a reliable customer support team, a complaints management process and experienced staff. All of these are factors that contribute to a more professional client experience.
- Flexibility – We have seen some of the most flexible accounts, fee structures and payment methods offered by some of the largest brokers. These firms have the resources and know-how to integrate additional flexibility into their platforms and apps, catering to a wide range of trading styles and needs.
Bottom Line
UK investors have several good options when looking at brokers with a large client base. Our team have found that some of the biggest brokers offer a premium, reliable and secure trading experience, while being able to cater to a range of trading strategies, interests and experience levels.
It is worth noting, however, that the size of a broker’s client base is not the only factor to consider when choosing a brand. Platforms, tools, instruments, fee structure, regulation and security should not be overlooked. Ultimately though, size can often be a good indication of reputation.

FAQ
Are Brokers With More Clients Better?
Brokers with the most clients are not necessarily better than those with fewer active users. However, a large client base tends to be an indication that a broker is trustworthy.
There are, of course, other factors to consider when choosing a brokerage, including UK regulations, platforms, tools and pricing.
