Best Online Trading Platforms UK 2026 — eToro, Trading 212, Hargreaves Lansdown Compared
Choosing the right trading platform could save you hundreds in fees every year. We compare the best UK online trading platforms for 2026 — covering stocks, ETFs, ISAs, fees and which wins for each investor type.
The UK online trading platform market has never been more competitive. Commission-free trading, fractional shares, and instant account opening have transformed retail investing — what used to require a stockbroker and a phone call now takes three minutes on a smartphone. But the sheer number of platforms available makes choosing the right one genuinely confusing.
The difference between platforms matters more than most investors realise. Platform fees, currency conversion charges, and dividend handling can quietly cost a long-term investor £500–£2,000 per year on a £50,000 portfolio. Choosing the wrong platform for your investment style is an expensive mistake.
This guide compares every major UK trading platform for 2026 — covering fees, asset range, ISA wrappers, and exactly which platform wins for each type of investor.
Quick Winners by Investor Type
Best Trading Platforms UK 2026 — Full Reviews
1. Trading 212 — Best Commission-Free Platform
Trading 212 has grown to become the UK's most popular trading app for retail investors, with over 3 million users. The reason is simple: zero commission on stocks and ETFs, no annual platform fee on their ISA, and fractional shares from as little as £1. For investors starting out or building a long-term ISA portfolio, the cost savings versus traditional platforms are substantial.
Their app is clean, intuitive and well-designed for mobile-first investors. The ISA wrapper is free — no annual charge — which means a £20,000 ISA investment costs nothing in platform fees per year versus £90/year at Hargreaves Lansdown. Over a 20-year investment horizon, that fee difference compounds significantly.
Trading 212 makes money primarily through currency conversion fees (0.15% on foreign currency trades), interest on uninvested cash, and their CFD product (which is separate from the investing platform and carries higher risk).
- Zero commission on stocks and ETFs — US and UK markets
- Free Stocks and Shares ISA — no annual platform fee
- Fractional shares from £1 — invest in Amazon, Tesla, Apple with any amount
- 5,000+ stocks and ETFs available
- AutoInvest feature for automatic regular investing
- 4.1% interest on uninvested cash (subject to change)
- FCA regulated — FSCS protected up to £85,000
- No SIPP (pension) available
- No financial research or analyst ratings
- Customer service primarily in-app — no phone support
- CFD product on same platform can confuse new investors
2. Hargreaves Lansdown — Best for Experienced Investors
Hargreaves Lansdown is the UK's largest investment platform with over 1.8 million clients and £150 billion under administration. Their platform is the most feature-rich available to UK retail investors — excellent research, comprehensive fund and share screeners, analyst ratings, regular market commentary, and the best mobile app in the market.
HL offers all major account types: Stocks and Shares ISA, Lifetime ISA, SIPP, and general investment accounts. Their customer service is exceptional — UK-based teams, phones answered quickly, and a walk-in office in Bristol for in-person support. For investors who value the full package and use the research and tools extensively, HL justifies the higher cost.
- Best research and fund analysis tools in the UK market
- 4,000+ funds, UK and global shares, ETFs, investment trusts
- ISA, Lifetime ISA, SIPP and general account in one place
- Award-winning mobile app
- UK-based customer service — phones answered within minutes

3. eToro — Best for Social Trading
eToro is the world's largest social trading platform with over 35 million registered users globally. Their defining feature is copy trading — the ability to automatically replicate the trades of successful investors on the platform in real time. You choose a trader to copy, allocate a sum, and their portfolio movements are mirrored proportionally in your account.
Beyond copy trading, eToro offers commission-free stock and ETF trading, a strong social feed where investors share ideas and analysis, and access to real cryptocurrencies alongside traditional assets. Their platform is well-designed for investors who want a community element alongside their investing.

- Commission-free stock and ETF trading
- Real crypto alongside stocks — BTC, ETH, 70+ assets

- Copy trading performance is not guaranteed
4. Interactive Investor — Best Flat-Fee Platform
Interactive investor charges a flat monthly fee — £12.99/month for the Investor plan — rather than a percentage of assets. This makes them increasingly competitive as your portfolio grows. For a £100,000 portfolio, ii costs £156/year versus £450/year at Hargreaves Lansdown — a saving of £294 annually. For £250,000, the saving versus HL exceeds £900 per year.
Interactive investor offers access to over 40,000 investments globally — shares, funds, ETFs, investment trusts, and bonds across UK and international markets. Their platform is comprehensive if less visually polished than HL, and their drawdown service for retirees is particularly well-regarded.
- Flat fee — cheapest for portfolios over £50,000
- One free trade per month included
- 40,000+ investments globally
- ISA, SIPP, and general account available
- Strong drawdown tools for retirees
- Which? Recommended investment platform

- Platform interface less intuitive than HL or Trading 212
- Research tools less comprehensive than HL

AJ Bell's Dodl app offers a simpler, lower-cost version of the platform at a flat 0.15% fee for those who want a more streamlined experience. For investors who want broad fund access, a SIPP, ISA and regular investing in one place at a competitive price, AJ Bell is the best all-rounder.

- Platform less polished than HL

Freetrade is a UK-built commission-free investing app that competes directly with Trading 212 for the mobile-first beginner market. Their basic account is completely free with commission-free trading in UK and US stocks and ETFs. Their Plus plan at £9.99/month adds an ISA, more markets, and limit orders.
Freetrade's clean, minimalist app is well-designed and particularly popular with younger UK investors. Their community forums and educational content make them a strong choice for investors who are just starting out and want a supportive learning environment alongside their investing.

ISA vs General Investment Account — Which to Use?
For most UK investors, the Stocks and Shares ISA should be the first port of call — all gains and dividends are completely free of UK tax, forever, with no annual reporting requirement.
| Account type | Tax on gains | Tax on dividends | Annual allowance | Best for |
|---|---|---|---|---|
| Stocks & Shares ISA | 0% | 0% | £20,000/year | Most investors — use this first |
| Lifetime ISA | 0% | 0% | £4,000/year | First-time buyers and under-40s saving for retirement |
| SIPP | 0% (deferred) | 0% | £60,000/year | Retirement savings — tax relief on contributions |
| General account | CGT (10%/20%) | Income tax | No limit | Investing beyond ISA/SIPP allowances |
Understanding Trading Fees — What to Watch For
Platform Fees vs Dealing Fees
Most platforms charge in two ways: a platform fee (percentage of assets per year or flat monthly fee) and a dealing fee per trade. For buy-and-hold investors who trade infrequently, the platform fee dominates — choose the lowest percentage. For active traders who buy and sell frequently, the dealing fee per trade matters more.
Currency Conversion Fees
When buying US or European stocks, you pay a currency conversion fee. This varies widely — Trading 212 charges 0.15%, Hargreaves Lansdown charges 1.0%, and eToro charges 0.5%. For a £10,000 US stock purchase, the FX fee difference between Trading 212 (£15) and HL (£100) is £85 per trade. Active US stock buyers should factor this in carefully.
Dividend Reinvestment
If you want dividends automatically reinvested, check whether the platform offers this and what it costs. Some platforms charge a dealing fee per reinvestment — on a diversified portfolio paying dividends quarterly, this can add up to £100–£200 per year in unnecessary fees.
