Why Fees Matter More for Beginners

Platform fees have an outsized impact on smaller portfolios. A 0.45% annual platform fee on a £5,000 portfolio costs £22.50 per year. On a £50,000 portfolio, that same rate costs £225. Beginners with smaller initial investments should prioritise platforms with low or zero percentage fees, or flat fees only where those fees are competitive at their portfolio size.

Trading 212: Best for Zero-Cost Beginners

Trading 212 charges no platform fee and no dealing commission on its ISA and general investment account. For a beginner investing small amounts, this is the lowest-cost entry point available. The minimum investment is £1, and the AutoInvest feature allows proportional allocation across multiple assets automatically.

The platform covers thousands of stocks and ETFs, including the major global index trackers. The interface is mobile-first and generally considered easy to navigate for new investors.

Vanguard: Best for Simple Index Fund Investors

Vanguard's 0.15% platform fee (capped at £375 per year) is competitive for investors who want simple, low-cost index fund investing. The fund range is limited to Vanguard's own funds and ETFs -- but this includes the full LifeStrategy range and the FTSE All World ETF, which cover most passive investing needs.

On a £10,000 portfolio, the Vanguard platform fee is £15 per year. This rises to £150 on a £100,000 portfolio, after which the cap kicks in.

Verdict for Beginners

For most beginners starting with less than £20,000: Trading 212 or InvestEngine on a DIY basis are the strongest cost options. For those who want Vanguard's specific fund range and simple platform experience: Vanguard's own platform is well-priced. Hargreaves Lansdown is not the lowest-cost option for beginners, but becomes more competitive at higher portfolio sizes.
