How to choose a UK trading broker

KEY TAKEAWAY Choosing a UK trading broker comes down to five things: regulation, costs, platform quality, market range and customer support. A broker should be FCA-authorised, transparent about its fees and spreads, and provide proper risk-management tools. Everything else is preference |
What should you look for in a broker?
The essentials are regulatory status, total cost of trading, the quality and reliability of the platform, the range of markets offered, and the standard of customer support. A broker strong in all five gives you a sound foundation; weakness in the first two — regulation and costs — should rule a broker out regardless of its other merits.
Why does FCA regulation matter?
FCA authorisation means a broker is supervised by the UK's financial regulator and its retail clients receive specific protections: negative balance protection (you cannot lose more than the funds in your account), leverage caps by asset class, segregation of client money from the firm's own funds, and access to the Financial Ombudsman Service and the Financial Services Compensation Scheme if things go wrong. You can check any firm's status on the FCA's Financial Services Register.
Brokers based offshore may advertise higher leverage because they sit outside these protections, so it is worth understanding exactly what is given up in exchange. Spreadex Ltd is authorised and regulated by the Financial Conduct Authority (registration number 190941). Any firm's status can be checked on the FCA's Financial Services Register.
How do you compare costs and spreads?
The main trading cost is usually the spread — the gap between a broker's buy and sell price. Tighter spreads mean a position starts less far behind. Beyond the spread, check overnight financing charges (the daily cost of holding leveraged positions open), any commission on share CFDs, and any non-trading fees such as inactivity charges — Spreadex charges no account or inactivity fees. The honest comparison is total cost for the way you intend to trade: a broker with tight spreads but higher financing charges suits someone trading frequently within the day better than someone holding positions for weeks or months.

QUICK FACT Offshore brokers can offer higher leverage because their clients sit outside FCA protections — including negative balance protection — that retail clients of UK-authorised firms receive automatically. |
What should you expect from the platform and tools?
A platform should be reliable under pressure — stable during volatile markets, fast to execute, and clear about the prices you're getting. Beyond the basics, look for proper charting, the risk-management tools that matter (stop-losses and guaranteed stops), and a mobile app that lets you manage positions away from a desk.
Why do market range and support matter?
A broad market range means you won't outgrow the broker as your interests widen — check coverage of the markets you actually intend to trade, whether that's UK shares, indices, forex or commodities. Support matters most when something goes wrong: a broker offering direct access to real people, by phone as well as online, is worth more than one hiding behind chatbots — particularly for traders managing leveraged positions where time can matter.

IMPORTANT TO KNOW Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. You should consider whether you understand how spread bets and CFDs work and whether you can afford to take the high risk of losing your money. |
Frequently asked questions
What makes a good trading broker?
FCA authorisation, transparent and competitive costs, a reliable platform with proper risk-management tools, coverage of the markets you want to trade, and accessible customer support. Regulation and costs are the two non-negotiables.
Is Spreadex FCA regulated?
Yes. Spreadex Ltd is authorised and regulated by the Financial Conduct Authority (registration number 190941) and has operated since 1999. Retail clients receive the protections that apply under FCA rules, including negative balance protection and segregation of client money.
What fees should I check before choosing a broker?
The spread on the markets you'll trade most, overnight financing charges if you'll hold positions open, any commissions, and any non-trading fees such as inactivity charges (Spreadex charges none). Compare total cost for your intended style of trading rather than any single headline number.
