It offers fractional shares from 1p, access to 12,000+ stocks and ETFs, and a flexible ISA allowing withdrawals and redeposits within the same tax year. The main limitation is no SIPP pension account and no third-party funds.
Best for Long Term Investing — Vanguard
Vanguard is the best platform for long term index fund investing. The 0.15% annual fee capped at £375 is the cheapest available in the UK for portfolios above £50,000. No dealing fees on funds. Strong SIPP and ISA options. Limitation: Vanguard's own 85+ funds only — no individual stocks or third-party funds.
Best All-Round Investment App — AJ Bell
AJ Bell offers the best balance of cost, range and reliability for most UK investors. Platform fee capped at £3.50/month for shares and ETFs in ISAs and general investment accounts. Wide range including shares, funds, ETFs and investment trusts. Full account range — ISA, Lifetime ISA, Junior ISA, SIPP. Which? Recommended for 8 consecutive years. AJ Bell is our top recommendation for most investors with £10,000–£250,000 portfolios.
Best for Large Portfolios — Interactive Investor
Interactive Investor's flat fee of £12.99/month (£155.88/year) makes it the cheapest option for portfolios above £30,000 where percentage-based fees become expensive. At £500,000, Interactive Investor costs £156/year vs £1,250 at AJ Bell. Subscription fees include one free trade per month and access to 40,000+ investments.
Best for Social Trading — eToro
eToro is unique in the UK market for copy trading — automatically mirroring experienced investors. Commission free on stocks and ETFs. No ISA wrapper. Currency conversion fee of 1.5% on GBP deposits is a significant ongoing cost. Best for copy trading specifically — not for tax-efficient long-term investing.

Investment App Fees — True Cost Comparison Over 10 Years
Fees compound over time just like returns do. Choosing the cheapest investment app for your situation can make a meaningful difference to your final portfolio value over a decade or more. Here is a true cost comparison for a £50,000 portfolio growing at 7% annually over 10 years across the main UK investment apps.
| Platform | Annual Fee on £50k | 10-Year Fee Total | Portfolio Value After Fees |
|---|---|---|---|
| Trading 212 | £0 | £0 | ~£98,358 |
| Vanguard | £75/yr | ~£1,050 | ~£97,300 |

| Interactive Investor | £156/yr | ~£1,560 | ~£96,800 |
| Moneybox | £237/yr (fee + subscription) | ~£3,320 | ~£95,000 |
Note: These are illustrative examples assuming a static portfolio value. Real portfolios grow, which means percentage-based fees increase in absolute terms as the portfolio grows — making flat-fee platforms increasingly cost-effective over time for larger portfolios.
Stocks and Shares ISA vs General Investment Account — Which First?
Always use your Stocks and Shares ISA allowance before investing in a General Investment Account (GIA). The ISA wrapper shields all gains and income from Capital Gains Tax and Income Tax permanently — not just for the current year. Money once inside an ISA stays sheltered for life, even if the ISA allowance rules change in future.
| Account Type | Annual Limit | CGT on Gains | Income Tax on Dividends | Best Use |
|---|---|---|---|---|
| Stocks and Shares ISA | £20,000/year | ❌ None — tax free | ❌ None — tax free | First priority — always max ISA first |
| General Investment Account | No limit | ✅ CGT applies above £3,000/year | ✅ Taxable above £500/year | After ISA allowance used up |
| SIPP Pension | £60,000/year | ❌ None inside pension | ❌ None inside pension | Retirement savings — cannot access until 57 |
Investment Apps for Specific Goals
| Goal | Best App | Why |
|---|---|---|
| Save for a first home (LISA) | Moneybox, AJ Bell or HL | All offer Lifetime ISA — 25% government bonus |
| Save for children (Junior ISA) | Vanguard or AJ Bell | Low fees for long-term child investing |
| Retire early (SIPP) | Vanguard or Interactive Investor | Cheapest fees for large pension pots |
| Generate passive income (dividends) | AJ Bell or Hargreaves Lansdown | Wide range of dividend-paying investment trusts and shares |

Investment App Safety — What FSCS Protection Means
All major UK investment apps are regulated by the Financial Conduct Authority (FCA) and eligible accounts are covered by the Financial Services Compensation Scheme (FSCS) up to £85,000 per person per firm. This means if an FCA-regulated investment platform were to fail, the FSCS would compensate eligible customers up to £85,000 for any money that could not be returned.
Importantly, FSCS protection covers the platform failing — not investment losses. If you invest £10,000 in a stock that falls to zero, the FSCS does not compensate you for the investment loss. It only covers the scenario where the platform itself becomes insolvent and cannot return your assets.
All platforms in this guide are FCA regulated and FSCS protected — with the exception of eToro's crypto holdings which are not FSCS protected.
