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
- The broker offers excellent services for beginners, featuring commission-free stock trading, a low minimum deposit, and an unlimited demo account.
- The trading app provides a top-tier social environment featuring an engaging feed and community chat, which we enjoy using.
- Utilising TradingView, the charts provide robust tools for technical analysis, featuring nine chart types and more than 100 indicators.
Cons
- 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.
- The only significant contact option, besides the in-platform live chat, is limited.
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
- In 2025, Plus500 expanded its range of share CFDs to include emerging sectors such as quantum computing and AI. This update opened up trading 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.
- The customer support team consistently delivers reliable support around the clock through email, live chat, and WhatsApp.
Cons
- Compared to competitors like IG, Plus500 offers limited research and analysis tools.
- The lack of social trading features prevents users from copying trades made by seasoned traders.
- Algorithmic trading and scalping are not available, potentially deterring certain traders.
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
- The broker recently expanded its range of CFDs, offering more trading opportunities.
- Opening a live account is both straightforward and swift, requiring under 5 minutes to complete.
- Vantage upholds a high trust score through its solid reputation, backed by premier regulation from the FCA and ASIC.
Cons
- It's unfortunate that some clients must register with the offshore firm, which provides reduced regulatory safeguards.
- Regrettably, cryptocurrencies are accessible solely to clients in Australia.
- 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
- Interactive Brokers has been awarded Best US Broker for 2025 by DayTrading.com. This accolade highlights its dedication to traders in the US, offering exceptionally low margin rates and access to global markets at minimal expense.
- IBKR offers an economical environment for traders, featuring low commissions, narrow spreads, and a clear fee structure.
- The new IBKR Desktop platform combines the top features of TWS with customised tools such as Option Lattice and MultiSort Screeners, providing an impressive trading experience for traders of all skill levels.
Cons
- The learning curve for TWS is quite steep, making it tough for novice traders to navigate and grasp all its features. In contrast, Plus500's web platform is far more accessible for those new to trading.
- 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.
- You are limited to a single active session per account, meaning you cannot use both your desktop programme and mobile app at the same time. This restriction can occasionally lead to a frustrating experience for traders.
Our Take On IronFX
"IronFX is ideal for seasoned forex traders seeking fixed or floating spreads. Offering over 80 currency options, it surpasses many competitors and provides excellent forex market research tools."Tobias Robinson
Reviewer
Pros
- In addition to MT4, the broker also provides various services such as copy trading, a VPS solution, and PAMM/MAM accounts.
- The IronFX Academy provides outstanding educational resources for traders of all levels, from beginners to advanced.
- IronFX offers both fixed and floating spread accounts, appealing to novices and seasoned traders alike.
Cons
- In comparison to top brokers, IronFX provides a limited range of share CFDs.
- Commissions in zero-spread accounts begin at £13.50 per lot, almost twice the industry standard.
- It is unfortunate that the broker lacks advanced software options like MT5 or TradingView, restricting choice for seasoned traders.
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
- Setting up an XTB account is straightforward and fully online, requiring only a few minutes. This simplicity eases new traders into the world of trading.
- 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.
- Top-notch customer support, available 24/5, includes a welcoming live chat with response times under two minutes during tests.
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 research tools at XTB are commendable but have the potential to excel further. Enhancing them with access to top-tier third-party services like Autochartist, Trading Central, and TipRanks would significantly elevate their offering.
- XTB has stopped supporting MT4, restricting traders to its own platform, xStation. This decision may discourage experienced traders accustomed to using the MetaTrader suite.
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
- 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.
- 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.
Cons
- 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.
- 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.
- 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.
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?
