Online Trading Platform Fees UK 2026 — Full Comparison
Trading platform fees have a significant impact on investment returns over time. UK platforms charge in two main ways: percentage fees (a percentage of your portfolio value annually) which favour small investors, and flat fees (a fixed monthly or annual charge) which favour larger investors.
Source: Provider fee schedules as of April 2026. HL and AJ Bell fees updated March 2026. Always verify current fees directly with the provider — these change. All providers listed are FCA-regulated. Check the FCA register at register.fca.org.uk before depositing money with any investment platform.
CFD Trading UK: Risk Warning
CFDs (Contracts for Difference) are complex financial instruments that allow you to speculate on price movements without owning the underlying asset. They involve leverage — meaning you can gain or lose more than your initial deposit.
FCA-mandated risk disclosure: According to FCA data, between 51% and 84% of retail investor accounts lose money when trading CFDs, depending on the provider. The FCA requires all UK CFD providers to display the percentage of retail accounts that lose money on their platform.
CFDs are not suitable for most retail investors. If you are looking to build long-term wealth, a stocks and shares ISA or SIPP investing in diversified funds is almost always a better approach than CFD trading.
Stocks and Shares ISA vs General Trading Account
What is the best online trading platform in the UK 2026?
The best platform depends on your portfolio size and trading style. For beginners wanting low cost, Trading 212 and Freetrade offer commission-free trading with no annual platform fees. For larger portfolios or ISA/SIPP investors, Hargreaves Lansdown offers the widest investment range and best research tools, though at higher cost. Interactive Investor is cheapest for large portfolios above £50,000 due to its flat monthly fee structure. All FCA-regulated platforms are covered by the FSCS up to £85,000.
Are online trading platforms safe in the UK?
UK investment platforms regulated by the FCA are protected by the Financial Services Compensation Scheme (FSCS) up to £85,000 per person per institution if the platform fails. However, FSCS does not protect against investment losses — if your investments fall in value, you bear that loss. Always check the FCA register at register.fca.org.uk before depositing money. Never invest with platforms not on the FCA register.
What is the cheapest way to invest in the UK?
The cheapest way to invest in the UK is through a commission-free platform like Trading 212, which charges no platform fee and no trading commission on stocks and ETFs. For long-term investors focused on index funds, Vanguard's 0.15% annual fee capped at £375 is highly competitive. As your portfolio grows above £50,000–£100,000, Interactive Investor's flat monthly fee typically becomes cheaper than percentage-based platforms.
How much do I need to start investing in the UK?
Many UK investment platforms allow you to start investing with as little as £1. Trading 212, Freetrade, and eToro all support fractional share investing — buying a fraction of an expensive share like Amazon or Alphabet. There is no minimum investment required for most ISA or general trading accounts on major UK platforms. However, some platforms have minimum deposit requirements — check before opening an account.
What is the capital gains tax allowance for investors UK 2026/27?
The Capital Gains Tax (CGT) annual exempt amount for 2026/27 is £3,000. This means you can realise up to £3,000 in investment gains in a single tax year without paying CGT. Gains above this threshold are taxed at 18% for basic-rate taxpayers and 24% for higher-rate taxpayers on investment assets (rates updated in 2024 Budget). Gains inside a stocks and shares ISA or SIPP are always CGT-free regardless of amount.
