What to Look for in UK Online Brokers
Choosing an online broker in the UK means weighing regulation, cost, platform usability, and the range of assets you want to trade. The Financial Conduct Authority (FCA) oversees all legitimate brokers operating in Britain, and client money must be held in segregated accounts with protection up to £85,000 under the Financial Services Compensation Scheme. Before you open an account, check the FCA register and confirm the firm is authorised, not just advertising UK services from an overseas licence.

Beyond regulation, the real differentiator is usually cost structure. Most UK brokers now offer commission-free trading on shares and ETFs, but they make money on spreads, overnight financing, inactivity fees, and withdrawal charges. If you trade frequently, a small spread advantage can save hundreds of pounds a year. If you hold positions overnight or trade derivatives, funding and borrowing rates matter just as much as entry commissions.
Types of Online Brokers Available in the UK
The UK market splits into several distinct models, each suited to different styles of investing.
Execution-Only Platforms
Platforms like Hargreaves Lansdown, Interactive Investor, and AJ Bell provide trade execution without advice. You place the order yourself, choose your investments, and manage the portfolio. These brokers typically charge a monthly or annual platform fee plus dealing commissions, though many now offer commission-free share dealing with a funded account or monthly subscription. They are the backbone of DIY investing in Britain, and their fund supermarkets make building a diversified portfolio straightforward.
Spread Betting and CFD Providers
Providers such as IG, CMC Markets, and Pepperstone offer leveraged products like spread bets and contracts for difference. These allow you to gain exposure to shares, indices, forex, and commodities without owning the underlying asset. Profits and losses are magnified by leverage, and most UK retail clients lose money with these instruments. They are useful for short-term trading but require strict risk management and a clear understanding of margin and overnight charges.
Robo-Advisors and Managed Portfolios
For investors who want a hands-off approach, robo-advisors like Nutmeg, Moneyfarm, and Wealthify build and maintain portfolios based on your risk profile. They charge an annual management fee, usually between 0.25% and 0.75%, and the underlying ETFs or funds have their own ongoing charges. These services suit beginners or anyone who prefers not to pick individual funds or shares.
Fees and Charges Compared
Understanding the full cost of trading means looking past headline commission rates. Below is a breakdown of the common charges you will encounter with UK online brokers.
| Fee Type | Typical Range | What It Covers |
|---|---|---|
| Share dealing commission | £0 to £11.95 per trade | Execution of a buy or sell order on the London Stock Exchange or major global exchanges |
| Platform / monthly fee | £0 to £12.95 per month | Account holding, portfolio viewing tools, and research access |
| Foreign exchange fee | 0.15% to 1.5% of trade value | Currency conversion when trading international shares or ETFs |
| Overnight financing (CFDs) | Approx. 2% to 15% annualised | Cost of holding a leveraged position overnight |
| Inactivity fee | £0 to £12 per month | Charged when no login or trading activity for a set period |
| Withdrawal fee | £0 to £5 per withdrawal | Cost of returning funds to your bank account |
The cheapest broker for one investor may be expensive for another. A buy-to-hold investor with a large portfolio will feel platform fees more than dealing commissions, while a frequent trader will prioritise low execution costs and fast order routing.
Regulation and Investor Protection
The FCA requires all UK brokers to comply with strict rules on client money, conflict of interest, and complaints handling. If something goes wrong, you can escalate your complaint to the Financial Ombudsman Service. Always verify a broker's FCA registration number before depositing funds, and be wary of firms that promise unusually high returns or pressure you to deposit quickly. Unregulated or offshore brokers operating in the UK without FCA authorisation should be treated with caution, even if their platforms look polished.
Matching the Broker to Your Investing Style
The best online broker in the UK for you depends on what you want to do. If you are building a long-term portfolio of shares and funds, an execution-only platform with low platform fees and a strong fund library is the natural choice. If you trade derivatives, look for tight spreads, fast execution, and transparent margin rates. If you want guidance without a human adviser, a robo-advisor removes the guesswork. In every case, open a demo or small account first, test the platform, and confirm that withdrawal and deposit processes work smoothly before committing larger sums.
