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?

No. InvestEngine’s Stocks & Shares ISA is not a flexible ISA — any withdrawal permanently uses up that portion of your annual £20,000 allowance, even if you redeposit within the same tax year. If flexibility matters to you, Trading 212 offers a flexible ISA with a similar zero-fee ETF proposition.

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).
