Investing used to feel like something reserved for people in suits with six-figure salaries. Not any more. In 2026, you can start building a portfolio from your phone with as little as £1, and several of the best UK investment apps offer free shares just for signing up.
But with so many platforms available, picking the right one matters — especially when you're starting out. The wrong app can mean confusing jargon, hidden fees, or features you'll never use.
We've compared the top investment apps available to UK beginners to help you find the best fit. Every app on this list is FCA-regulated, offers a straightforward experience for beginners, and keeps costs low.

What to Look for in a Beginner Investment App
Before diving into the list, here's what actually matters:
- Low or zero fees — High fees eat into returns, especially with smaller portfolios
- Simple interface — You shouldn't need a finance degree to buy your first share
- ISA availability — A Stocks and Shares ISA means gains are tax-free up to £20,000/year
- Fractional shares — The ability to buy a slice of expensive shares like Amazon or Apple
- FCA regulation — Non-negotiable for the safety of your money in the UK
1. Trading 212 — Best Overall for Beginners
Minimum deposit: £1 | Commission: £0 | ISA: Free | Fractional shares: Yes
Trading 212 consistently tops UK beginner lists. The app is clean, intuitive, and genuinely commission-free for buying and selling stocks and ETFs.
Key highlights:
- Zero commission on all stock and ETF trades
- Free Stocks and Shares ISA — no annual platform fee
- Fractional shares from £1 — invest in any company regardless of share price
- AutoInvest pies — set up automated, diversified portfolios
- Free share bonus when you sign up through a referral link
- Interest on uninvested cash — currently around 5.1% AER
The AutoInvest feature is particularly good for beginners. You create a "pie" of different stocks or ETFs, set how much to invest each month, and Trading 212 handles the rest.

Best for: Complete beginners who want zero fees and a simple start.
2. InvestEngine — Best for Hands-Off Investing
Minimum deposit: £100 (managed), no minimum (DIY) | Commission: £0 | ISA: Free
InvestEngine is ideal if you'd rather not pick individual stocks. It offers two modes:
- Managed portfolio — InvestEngine builds and rebalances a diversified ETF portfolio for you, completely free. Most UK robo-advisers charge 0.25%–0.75% annually — InvestEngine charges nothing
- DIY portfolio — Choose from 700+ ETFs with zero commission
Key highlights:
- £0 management fee for managed portfolios — genuinely unique in the UK
- Automatic rebalancing keeps your portfolio on track
- Regular investing with automated monthly contributions
- Welcome bonus available through referral links
Best for: Beginners who want a managed, diversified portfolio without paying fees.
3. Freetrade — Best for Simple Stock Picking
Minimum deposit: £2 | Commission: £0 | ISA: £5.99/month | Fractional shares: Yes (US)
Freetrade is designed so anyone can buy their first share in minutes.
Key highlights:
- Zero commission on instant orders during market hours
- Clean, beginner-friendly interface with stock descriptions and key stats
- 6,000+ stocks and ETFs across UK, US, and European markets
- Fractional US shares from £2
- Free share worth up to £100 when you sign up via referral
The main drawback is the ISA fee — £5.99/month (£71.88/year). For small portfolios, this can meaningfully eat into returns. For larger portfolios, it becomes negligible.
Best for: Beginners who want a simple app for picking individual stocks.
4. eToro — Best for Social Investing
Minimum deposit: ~£40 | Commission: £0 on stocks | ISA: No | Fractional shares: Yes
eToro pioneered social investing — the idea that you can learn from and copy successful investors.
Key highlights:
- CopyTrader — automatically replicate the trades of top-performing investors
- Zero commission on real stock purchases
- Smart Portfolios — pre-built thematic portfolios (tech, renewable energy, etc.)
- Massive community with investor discussions and sentiment data
- Wide asset range — stocks, ETFs, crypto, commodities, forex
Important: eToro has a $5 withdrawal fee and a ~1.5% currency conversion fee since accounts are USD-denominated. No ISA is available, meaning your gains are subject to UK Capital Gains Tax.
Best for: Beginners who want to learn from experienced investors through copy trading.
5. Lightyear — Best for International Investing
Minimum deposit: £1 | Commission: £0 on US stocks | ISA: Free | Fractional shares: Yes
Lightyear has quickly earned a reputation for transparent, low-cost international investing.
Key highlights:
- Zero commission on US stocks — no hidden FX markup on USD trades
- Multi-currency account — hold GBP, USD, and EUR without conversion fees
- Competitive FX rate — 0.35% for currency conversion, among the lowest available in the UK
- Free Stocks and Shares ISA
- Interest on uninvested cash in multiple currencies
Most UK platforms charge a hidden FX fee of 0.5%–1.5% every time you buy a US stock. Lightyear lets you convert once and hold USD, saving significantly on repeated trades.
Best for: Beginners focused on US and international markets who want transparent FX costs.
Tips for Beginner Investors
- Use your ISA allowance — Your first £20,000/year in gains is tax-free inside a UK Stocks and Shares ISA. Always use this before a general investment account
- Start small and regular — Even £25/month adds up through compound growth. Monthly contributions also smooth out market ups and downs
- Diversify via ETFs — Don't put everything into one stock. A global ETF spreads risk across hundreds of companies automatically
- Think long-term — The stock market goes up and down. Historically, staying invested for 5+ years smooths out volatility
- Claim any referral bonus — Browse investment app referral codes on EasyEarns to get a free share or bonus when signing up
Which App Should You Choose?
For most UK beginners, Trading 212 offers the best all-round package — zero fees, free ISA, fractional shares, and AutoInvest for hands-off investing.
If you'd rather someone else manage your portfolio entirely, InvestEngine's free managed option is unbeatable.
If you want to learn from other investors, eToro's CopyTrader is worth exploring — just be aware of the FX and withdrawal fees, and the lack of ISA.
Frequently Asked Questions
Is it safe to invest through an app in the UK?
Yes, as long as the platform is FCA-regulated. All five apps on this list are FCA-authorised, meaning they must meet strict financial conduct standards. Your cash is also FSCS-protected up to £85,000 at most platforms.
How much money do I need to start investing in the UK?
As little as £1 on Trading 212 and Lightyear. You don't need thousands — small, regular contributions compound significantly over time. The more important thing is starting early rather than starting big.
What is a Stocks and Shares ISA?
A Stocks and Shares ISA is a UK tax wrapper that lets you invest up to £20,000 per tax year without paying Capital Gains Tax or Income Tax on your returns. It's the most important account for most UK investors — always use your ISA allowance before a general investment account.
Do I have to pay tax on investment gains?
Not inside an ISA. Outside an ISA, UK Capital Gains Tax applies above the annual allowance (£3,000 in 2026). Most beginner investors with smaller portfolios won't exceed this threshold, but it's worth being aware of as your portfolio grows.
Which UK investment app has the best referral bonus?
Trading 212 and Freetrade both offer a free share worth up to £100 when you sign up through a referral link. The value is random — most people receive £5–£20, but it could be higher. Browse current verified investment app referral codes on EasyEarns for up-to-date offers.
Should I use Trading 212 or Freetrade?
For most UK beginners, Trading 212 is the better choice — the ISA is completely free (Freetrade charges £5.99/month), and AutoInvest pies make it easy to automate investing. Freetrade has a slightly cleaner interface and offers a SIPP for pension investing, which Trading 212 doesn't.
