Every broker in this guide is FCA authorised, and eligible clients can access FSCS protection.

Hidden charges to watch before opening an account
Low trading fees do not always mean low overall costs. Before opening an account, check the charges that can affect your returns over time.
- FX conversion fees: Buying US shares involves currency conversion fees. Trading 212 charges 0.15%, while XTB, IG, and Capital.com charge 0.5%. On a £10,000 investment, that's a £35 difference compared with a 0.15% FX fee.
- Inactivity fees: Plus500 charges £10 per month after three months of inactivity. XTB, Capital.com, and Trading 212 do not charge inactivity fees.
- Platform and account fees: None of the five brokers charge ongoing platform fees for standard investing accounts. Always check the pricing before opening an account.
- Stamp Duty Reserve Tax (SDRT): Buying most UK-listed shares attracts 0.5% SDRT. This is a government tax, not a broker fee.
- Deposit and withdrawal fees: Some payment methods or large transactions may incur charges. Always check the broker's fee schedule.
How to choose a low-fee stock broker in the UK
Choosing a low-fee stock broker involves more than comparing £0 commission. Consider the overall cost, investment options, and FCA regulation before opening an account.
Define your investment profile
Your investment goals play a major role in choosing the right broker, regardless of how much money to start trading in the UK. The lowest-cost broker for one investor may not be the best option for another. Consider the following:
- Trading frequency: If you trade regularly, look for brokers with low dealing charges or commission-free trading where available.
- Investment products: Decide whether you want to invest in UK shares, US shares, or ETFs. Some brokers offer commission-free trading on selected products.
Understand the core fees and types of fees UK brokers charge
- Focus on the fees that matter most for your investing style. Some brokers charge £0 dealing fees, while others charge a fixed fee per trade.
- Even small dealing charges can add up over time. Some brokers also charge platform or account fees. If you are a long-term investor, recurring charges can reduce your overall returns.
- Minimum deposit requirements also vary. Some brokers allow you to start with a small amount, making them suitable for beginners.
Compare fee structure of shortlisted brokers
Compare the total cost of investing instead of focusing on a single fee. Pay attention to:
- Trading or dealing fees: Choose the £0 dealing fee broker if you are a frequent trader.
- Platform or account fees: If you hold a small portfolio, a flat fee can be a cheaper option for you. Percentage fees become expensive over time for large portfolio holders.
- FX conversion fees: Prefer a low FX fee or a multi-currency account if you invest outside the UK.
- Other fees: Do not ignore fees like inactivity fees, withdrawal fees or dividend reinvestment fees. A truly low-cost broker has few to no of these fees.
Verify broker regulation
- Verifying a broker's regulation is one of the most important steps when choosing a low-fee UK broker.
- Unregulated brokers may advertise zero commissions and ultra-low fees, but hidden costs can quickly add up. Learn how to spot scam brokers in the UK before opening an account.
- An FCA-regulated broker must clearly disclose its fees and comply with UK regulatory requirements. If you're comparing FCA vs offshore brokers, always check the level of investor protection.
- Eligible clients may be covered by the Financial Services Compensation Scheme (FSCS) for up to £85,000, subject to the scheme's rules and limits, and client money must be held in segregated accounts.
Our verdict: Which UK broker offers the best value?
The best broker depends on how you plan to invest, but a few stand out for different reasons.
- Best overall: IG offers the strongest combination of regulation, research tools, ISA options, and long-standing market presence. It also has the highest TC rating in this guide.
- Best for beginners: Capital.com is a good choice for new investors thanks to its £20 minimum deposit and easy-to-use mobile platform.
- Best for the lowest costs: Trading 212 offers zero commission on UK and US shares, a 0.15% FX conversion fee, and no platform or ISA fees, making it one of the lowest-cost options for long-term investors.
- Best for active investors: XTB combines no minimum deposit, commission-free stock and ETF trading up to its monthly limit, and the xStation 5 platform.
- Best for ISA investors: IG and XTB both offer stocks and shares ISA accounts, making them suitable for UK investors looking to invest tax-efficiently.
Conclusion
Keep in mind that you are not looking for the cheapest platform. You are only trying to balance fees with features and safety that align with the type of investing you plan. Choosing a slightly higher-fee regulated broker is cheaper than losing your capital.
Here is a checklist of what to see to finalise a low-fee UK broker:
- Does your broker charge trading fees? This leads to commissions adding up for active investors.
- Does your broker charge FX fees? This makes buying US stocks more expensive.
- Does your broker charge platform fees? This reduces your net profits if you hold long-term portfolios. Using strategies like scalping may turn unprofitable.
- Does your broker charge for withdrawals or deposits? This significantly affects traders’ profits, especially for those who make frequent transactions.
- Is your broker FCA-regulated? This is a mandatory requirement for your fund safety and protection.
Choose your broker by analysing its cost structure and comparing its features with competitors to find the most cost-effective option.
Pro Tip
Don't choose a broker based on £0 commission alone. Compare FX conversion fees, ISA availability, platform costs, and FCA regulation, as these can have a bigger impact on your long-term investing returns.
