Trading 212 has zero platform fee and zero commission, making it the cheapest UK ISA platform for almost any portfolio size. Vanguard Invest charges 0.15% capped at £375/yr but only lets you hold Vanguard funds and ETFs (until 2024 — now opened to non-Vanguard ETFs too). The trade-off: Trading 212’s lower fees vs Vanguard’s simplicity, low FX costs, and reputation.
Headline fees and structure
| Feature | Vanguard Invest | Trading 212 |
|---|---|---|
| Platform fee (ISA) | 0.15% capped at £375/yr | 0% — none |
| Commission per trade | £0 (Vanguard funds/ETFs); £7.50 (other ETFs, dealing fee) | £0 — none |
| Fund OCFs typically | 0.06% — 0.22% (Vanguard own funds) | 0.06% — 1.50% (full UK universe) |
| FX fee on USD holdings | Built into ETF costs (varies) | 0.15% |
| Available wrappers | ISA, JISA, SIPP, GIA | ISA, Cash ISA, GIA, CFD (but not SIPP) |
| Min lump sum | £500 (or £100/mo regular) | £1 (effectively no minimum) |
| Fractional shares | No | Yes |
| Available products | Vanguard funds + ETFs + selected non-Vanguard ETFs | 10,000+ stocks and ETFs (most LSE + US-listed) |
| Interest on uninvested cash | Yes (Vanguard money market funds) | Yes (variable, 3-5% historic in 2024) |
| FSCS protection | £85,000 per person | £85,000 per person |
| Regulated by FCA | Yes | Yes (UK arm) |
Cost over 30 years — the headline difference
Compounding the fee gap matters enormously over long horizons. Two investors, both with £500/month going into a global equity ETF, both retiring after 30 years with 7% nominal return:
| Platform | Annual cost | Pot after 30 years | Pot vs no-fee benchmark |
|---|---|---|---|
| Trading 212 | ~0.07% (just the fund OCF) | ~£586,000 | −£3,500 |
| Vanguard Invest | ~0.22% (platform + OCF) | ~£574,000 | −£15,500 |
| HL (for comparison) | ~0.52% (platform + OCF) | ~£546,000 | −£43,500 |
The Trading 212 vs Vanguard cost gap of ~£12,000 over 30 years is meaningful but not life-changing. The gap to a premium platform like HL is much wider. Note: Vanguard’s 0.15% fee is capped at £375/yr — meaning above £250k portfolio the percentage drops sharply.
Where Vanguard Invest wins
- Reputation and stability. Vanguard is a $9 trillion AUM global asset manager with a 50-year track record. Trading 212 has been UK-regulated since 2018 and is a startup.
- Fund OCF efficiency. Vanguard’s own funds are among the cheapest in the world (FTSE Global All Cap at 0.23% TER, S&P 500 ETF at 0.07%). On Trading 212 you can hold the same funds but the OCF stays — you don’t save on the fund-cost side.
- Simplicity. Vanguard Invest’s interface is deliberately minimal. Three accounts (ISA, JISA, GIA), four LifeStrategy ready-made portfolios, ~80 index funds and ~70 ETFs. Hard to make a mistake.
- SIPP available. Vanguard offers a SIPP at 0.15%/yr (capped at £375). Trading 212 does not offer a SIPP yet.
- Junior ISA available. Vanguard JISA at 0.15%/yr. Trading 212 does not offer a Junior ISA.
- Built-in money market fund cash. Uninvested cash earns the Vanguard Sterling Short Term Money Market Fund yield (~4.5% in 2026), automatically. No separate setup.
Where Trading 212 wins
- Zero platform fee. Unique among major UK ISA platforms. For any portfolio size, you pay nothing to Trading 212 directly.
- Zero commission. Buying or selling shares/ETFs costs nothing. Even AJ Bell’s £1.50 regular savings rate is more than zero.
- Massive product range. 10,000+ stocks and ETFs vs Vanguard’s ~150 — almost the entire LSE and most US shares are tradeable.
- Cash ISA available. Trading 212’s Cash ISA offers competitive variable rates (typically 4-5% AER). One single login covers Stocks & Shares ISA, Cash ISA and GIA.
- Fractional shares. Lets small investors buy slices of expensive shares (e.g. Berkshire Hathaway at ~$680k/share, Tesla at ~$300/share). Vanguard does not support this.
- Better app. Trading 212’s mobile app is consistently rated more responsive than Vanguard’s.
Decision framework
Choose Vanguard Invest if you...
Best for: ...want a SIPP or Junior ISA, value institutional reputation, are happy with Vanguard’s fund range, hold >£250k (where the £375 fee cap makes the percentage drop), or prefer the simplicity.
Vanguard's £375 fee cap effectively makes large portfolios fee-free above £250k. The combination of low fund OCFs and a flat platform cap makes Vanguard SIPP especially attractive for high earners.
Choose Trading 212 if you...
Best for: ...want a zero-fee ISA, like buying individual shares, want both Cash ISA and S&S ISA under one login, are starting small (under £10k), or value the better mobile app.
Trading 212 is the cheapest UK ISA platform in absolute terms. The lack of SIPP is the main gap — combine with Vanguard SIPP for the full setup.
Use both if you...
Best for: ...max your £20k ISA each year and want different exposures.
Many investors run a Trading 212 ISA for shares + a Vanguard ISA for funds. You can split the £20k annual allowance across multiple ISAs of different types (from April 2024 — Multiple ISAs of the Same Type were re-permitted).
