Bottom line up front: For most UK beginners, Trading 212 is the best starting point — zero commission, a 5.2% cash ISA rate, and a clean app. If you want pure ETF investing at the lowest possible cost, InvestEngine wins. For a full service including a SIPP, go with Hargreaves Lansdown.

#1 Trading 212 — Best overall for UK beginners
The best all-round investing app for most UK investors in 2026. Zero-commission stocks and ETFs, a market-leading 5.2% AER cash ISA, and one of the cleanest mobile apps available.
Watch out for: No SIPP available. Currency conversion fees (0.15%) apply on US stock trades. Customer support can be slow during busy periods.
Trading 212 launched its zero-commission model in 2017 and has since become the most downloaded investing app in the UK. It's FCA-regulated, and your cash is protected by the Financial Services Compensation Scheme (FSCS) up to £85,000.
The standout feature in 2026 is the cash ISA rate. At 5.2% AER, it beats most easy-access savings accounts and many cash ISAs at high street banks. If you're not ready to invest yet but want to use your £20,000 annual ISA allowance, parking it in Trading 212's cash ISA while you decide is a smart move.
#2 Freetrade — Best for Stocks & Shares ISAs
Commission-free UK and US stocks with a clean, simple app. The Stocks & Shares ISA costs from £4.99/month — excellent value for regular investors wanting tax-free growth.
Watch out for: The free Basic plan limits you to a general investment account only — you'll need to pay for ISA access. Fewer stocks available than larger platforms like HL.
Freetrade is a strong pick if a Stocks & Shares ISA is your priority. At £4.99/month for the Standard plan, you get ISA access and commission-free trading — far cheaper than traditional brokers charging £10+ per trade.
The app's simplicity is a genuine strength. Unlike some platforms that overwhelm you with charts and data, Freetrade keeps things clean. It's built for people who want to invest regularly and let it grow, not for day traders.
#3 InvestEngine — Best for ETF investors
ETF-only platform with zero platform fees on DIY portfolios. The most cost-efficient option for passive investors following an index fund strategy — no platform charge, just the fund's own fee.
Watch out for: ETFs only — no individual stocks. £100 minimum deposit. Managed portfolio option does charge a fee (0.25%).
If you've read about index fund investing — buying a simple fund that tracks the whole market rather than picking individual stocks — InvestEngine is the cheapest place to do it in the UK. Zero platform fee means more of your money stays invested.
For context: on a £10,000 portfolio, a 0.25% annual platform fee costs £25 a year. At InvestEngine, that's £0. Over 20 years of compounding, that difference becomes meaningful.
#4 Hargreaves Lansdown — Most established
The UK's largest investment platform, trusted by over 1.8 million investors. More expensive than newer apps, but unmatched in breadth — stocks, funds, ISAs, SIPPs, and financial planning tools all in one place.
Watch out for: At £11.95 per share trade, fees are high for frequent traders. Not the right choice if you're starting with a small amount — fees will eat into your returns. Best suited to investors with £5,000+ who trade infrequently.
Hargreaves Lansdown's higher fees are justified if you want everything in one place — ISA, SIPP, funds, shares, and proper financial research. For a beginner putting £50/month into a simple ETF, it's overkill. But if you're building serious long-term wealth and want a trusted, established platform, HL is the gold standard in the UK.
How to choose the right investing app
The right platform depends on what you're actually trying to do. Here's a simple framework:
If you're a complete beginner
Start with Trading 212. You can open an account with £1, there are no commissions, and the app won't overwhelm you. Put your money in a global ETF like the Vanguard FTSE All-World (VWRL) and let it grow.
If tax-free investing is your priority
Open a Stocks & Shares ISA — every UK adult gets a £20,000 annual allowance where gains and income are completely tax-free. Trading 212, Freetrade, and InvestEngine all offer ISAs. Use your allowance every year if you can.
If you want to invest in ETFs only
InvestEngine is the cheapest option. Zero platform fees, free ISA, and a great selection of index funds. It's specifically built for this style of investing.
If you want to plan for retirement
You need a platform with a SIPP (Self-Invested Personal Pension). Freetrade, InvestEngine, and Hargreaves Lansdown all offer SIPPs. Money in a SIPP gets government tax relief — a 20% basic rate taxpayer investing £80 gets £100 added to their pension.
Important: All four platforms above are regulated by the Financial Conduct Authority (FCA) and your cash is protected by the Financial Services Compensation Scheme (FSCS) up to £85,000. Your investments, however, can go up and down — capital is at risk.
Our verdict
Trading 212 for most people. InvestEngine for pure ETF investing. HL for serious long-term investors.
There's no single best investing app — it depends on your goals. But for the majority of UK investors starting out in 2026, Trading 212 offers the best combination of low cost, ease of use, and features. Open a Stocks & Shares ISA, set up a monthly direct debit into a global ETF, and let time do the work.
