Vanguard ISA Review 2026

Overview

Vanguard is the world’s second-largest asset manager and a pioneer of low-cost index fund investing. Their UK investor platform offers a simple, focused service — but you can only invest in Vanguard’s own funds and ETFs.

The platform fee of 0.15%, capped at £375/year, is among the lowest percentage-based charges available.

The Vanguard approach

Vanguard’s philosophy is simple: minimise costs, invest in broadly diversified index funds, stay the course. The platform reflects this — there’s no research into individual shares, no ability to buy other providers’ funds. It’s a focused tool for a focused strategy.

Who is Vanguard best for?

• Passive investors who want to invest in index funds and nothing else
• Portfolios up to £250,000 where the 0.15% fee is competitive
• Investors who want simplicity over breadth

Who should look elsewhere?

• Active investors who want to pick individual shares or funds from other providers
• Portfolios over £250,000 where flat-fee platforms like ii become much cheaper

Verdict

For simple, low-cost passive investing in Vanguard funds, this is an excellent choice. The restriction to Vanguard’s range is the key limitation. Use our calculator to compare against other platforms at your portfolio size.
