InvestEngine ISA & SIPP Review 2026

Overview

InvestEngine offers one of the most compelling propositions in UK investing: a Stocks & Shares ISA with zero platform fee. You pay nothing to InvestEngine for holding your investments — only the underlying fund costs (OCF) apply. It’s FSCS-protected up to £85,000, the same as any FCA-regulated UK platform.

The catch: InvestEngine only offers ETFs. No funds, no investment trusts, no individual shares.

Is the InvestEngine ISA flexible?

Yes. InvestEngine’s Stocks & Shares ISA is a flexible ISA. You can withdraw money and pay it back into the same InvestEngine ISA before the end of the tax year (5 April) without it using up more of your £20,000 allowance. When you add money after a withdrawal, InvestEngine counts it as a replacement first, before it uses any remaining allowance.

How it works

InvestEngine makes money through its managed portfolio service (where they charge 0.25% per year) and through interest on cash balances. The DIY ETF ISA remains free.

Who is InvestEngine best for?

• ETF-focused passive investors who don’t need funds or shares
• Cost-minimisers for whom zero platform fees are the goal
• Any portfolio size — there’s no point at which a paid platform becomes cheaper for ETF investing

Limitations

• ETFs only — no funds, shares, or investment trusts
• Smaller range than HL or AJ Bell
• Less comprehensive research and tools

Verdict

For pure ETF passive investing, InvestEngine is extremely difficult to beat on cost. If your strategy is a small number of index ETFs and nothing more, the zero fee is compelling. Compare against Vanguard (which has a similar approach but charges 0.15%) and Trading 212 (also free, broader but more trading-focused).
