What passive investing needs from a platform

Passive investing's edge comes from cost discipline. A 0.5% platform fee eats about 15% of your terminal wealth over 30 years at 6% returns. That's why passive investors care about platform cost far more than active fund pickers do — the whole point is capturing market returns minus a very small tax.

InvestEngine — designed for passive investors

ETF-only DIY portfolios at 0% platform fee. Support for auto-invest and rebalancing (you set target weights; new contributions flow to underweight positions automatically). Fractional ETFs support (£25/month contributions work perfectly).

Best for: the classic UK passive investor — Vanguard FTSE All-World or iShares MSCI World in a Stocks & Shares ISA, monthly standing order, buy-and-hold forever.

Trade-offs: No LifeStrategy funds (they're OEICs, not ETFs). No LISA or JISA.

Hargreaves Lansdown — passive with extras

HL supports Vanguard LifeStrategy, HSBC Global Strategy, and all major UCITS ETFs. Fees are higher (0.45% on funds, £45 cap on ETFs) but you get research, phone support, LISA, JISA, and the option to explore active or share investing later.

Best for: passive investors who might want to hold LifeStrategy (funds, not ETFs) and value the research/support layer.

Vanguard Investor UK — LifeStrategy-only route

0.15% platform fee capped at £375/year. Free fund/ETF dealing. Only Vanguard products. If you've decided LifeStrategy 80% is your portfolio, this is the cheapest UK route (£375 cap vs uncapped 0.45% at HL).

Not an approved PennyWise affiliate; we mention it editorially because for the specific Vanguard LifeStrategy holder, it's genuinely the cheapest option.

Frequently asked questions

What is passive investing?

Investing by tracking a market index — typically via a fund or ETF like Vanguard FTSE All-World — rather than picking individual stocks or paying an active manager. Aims to capture market returns minus a tiny cost.

Which ETF is best for passive investing?

Vanguard FTSE All-World (VWRP) or iShares MSCI World (SWDA). Both cover thousands of companies globally at 0.20% OCF. See our ETFs explained guide.

Do I need to rebalance?

Only if you hold multiple funds. A single global ETF or Vanguard LifeStrategy rebalances internally. See our portfolio rebalancing guide.

How much can passive investing return?

Long-run global equity returns average 6-8% real. Individual years vary widely — -25% happens. Time in market matters more than timing.

Is passive investing safe?

Carries market risk (values fall too) but not manager risk or company-specific risk. Widely considered lower-risk than active investing for long-term outcomes.
