Other Trading Platforms

Beyond the seven uk stock brokers listed above, there were five other platforms we reviewed: Barclays, AJ Bell Youinvest, Lloyds Bank, eToro, and Halifax. Here's our high-level takeaways for each broker.

Barclays, "Barclays Smart Investor offers average share dealing commissions (£6 per trade) alongside a good selection of research tools and education. However, there is no dedicated mobile app for share dealing, and the trading tools offered are just average."

AJ Bell Youinvest, "AJ Bell Youinvest offers a mediocre trading platform and decent research tools, including in-house articles and videos. Ultimately, AJ Bell struggles to deliver value in the UK market against brokers that offer a better platform at a lower price point."

Lloyds Bank, "Lloyds Bank can deliver value to the passive fund trader, who places a few fund trades each year and requires little research. Outside of this customer mold, Lloyds quickly becomes expensive (stock trades cost £8 - £11) and can’t provide the same trading tools or research as top UK brokers."

eToro, "eToro is great for traders seeking zero-commission stock trades, an efficient platform, and access to copy trading. That said, there are hidden fees, education is sub-par, and eToro doesn't offer the same range of investments as traditional brokers. Your capital is at risk." Read full review

Halifax, "Halifax offers competitive pricing for passive fund traders but quickly becomes expensive for those who trade stocks at least once a month. Halifax provides no dedicated mobile application and, overall, is average compared to industry leaders."

Runner-Up: Interactive Brokers

Professional traders are brilliantly serviced with the trading tools, range of investments, and capabilities of Interactive Brokers. Meanwhile, less-experienced traders can still take advantage of the low commissions and excellent research through the web-based Client Portal platform.

  • Pricing: With both tiered and fixed commission structures, Interactive Brokers can be one of the cheapest options available, especially for professionals, depending on trading volume and frequency. However, the casual trader must consider inactivity fees, which can be as high as USD 20 per month, for not reaching the minimum monthly commission quota.
  • Trading platform: Trader Workstation (TWS), Interactive Brokers’ downloadable platform, is packed with dozens of industry-leading tools professionals and institutions will appreciate. For inexperienced investors, the Client Portal web-based platform is straightforward and powerful enough to use as a trading platform, thanks to the Fundamentals Explorer tool.
  • Investments: While Interactive Brokers does not offer ISA/SIPP accounts directly to UK residents, globally, customers can trade across more than 135 international markets in 33 countries. In addition to stock trading, Interactive Brokers offers ETFs, funds, investment trusts, warrants, options, futures, forex, bonds, and CFDs.
