InvestEngine Review (2026)
*InvestEngine (UK) Limited is authorized and regulated by the Financial Conduct Authority (FCA, FRN 801128). Eligible client funds and securities are protected up to £85,000 by the Financial Services Compensation Scheme (FSCS). £0 platform fee applies to DIY portfolios across General Investment Accounts (GIAs), Stocks & Shares ISAs, Business Accounts, and Self-Invested Personal Pensions (SIPPs). Managed portfolios incur a 0.25% annual management fee. Underlying ETF ongoing charges (TER) apply. Capital at risk.
The Vibe Check
"InvestEngine has pulled off something that once seemed mathematically impossible in British wealth management: a **completely free, zero-platform-fee Stocks & Shares ISA and SIPP for DIY investors** with **zero dealing commissions on over 700+ London-listed ETFs**. While Hargreaves Lansdown extracts an uncapped 0.45% platform fee plus £5.95 to £11.95 per trade, and AJ Bell caps share custody at £3.50/month in an ISA and £10/month in a SIPP, InvestEngine charges a clean **£0.00**. Combined with automated **Variable Recurring Payments (VRP) from £10**, fractional ETF shares down to penny increments, and an affordable **0.25% fee for managed LifePlan portfolios**, it is the purest passive compounding vehicle available to UK Bogleheads. But you must understand how they monetize their 'free' model: InvestEngine executes a **100% uninvested cash interest skim**—they retain every single basis point of interest earned on uninvested cash balances in your account. Furthermore, you **cannot trade individual company stocks or investment trusts**, there is **no real-time intraday market execution (all trades execute in a single daily batch around 2:00 PM)**, and there are **no limit or stop-loss orders**."
The Fine Print: Valerie's InvestEngine Fee Audit
InvestEngine operates on an unbundled, transparent fee structure that completely eliminates traditional retail account custody tolls:
| Service / Wrapper | InvestEngine Pricing Schedule | Valerie's Audit Notes |
|---|---|---|
| DIY Portfolios (GIA & ISA) | £0.00 Platform Fee (£0 Comm) | 100% free self-directed ETF investing. Zero ticket commissions, zero platform custody charges, and zero ISA administration fees. |
| DIY SIPP (Pension Wrapper) | £0.00 Platform Fee (£0 Comm) | Abolished its SIPP platform fee, making it one of the only completely free self-directed ETF pension wrappers in the UK. |
| Managed Portfolios & LifePlans | 0.25% Per Annum (Daily Accrual) | Automated risk-rated model portfolios managed by InvestEngine's investment committee. Billed monthly in arrears. |
| ETF Trade Execution | £0.00 Commission (All ETFs) | Free to buy and sell all 700+ eligible London Stock Exchange (LSE) exchange-traded funds. No dealing ticket tolls. |
| Underlying ETF Ongoing Charges | 0.03% – 0.45% TER (Average 0.12%) | Standard fund manager Total Expense Ratio (TER) deducted within the ETF's Net Asset Value (e.g., 0.07% on Vanguard S&P 500 VUSA). |
| Foreign Exchange (FX) Markup | £0.00 (Zero FX Fee) | All eligible ETFs are GBP-denominated on the LSE. No internal currency conversion markups applied on trading. |
| Uninvested Cash Yield | 0.00% APY (100% Retained) | ⚠️ Platform monetization model. InvestEngine retains 100% of the interest earned on uninvested cash to fund £0 platform operations. |
| Account Inactivity Toll | £0.00 (Zero Inactivity Tolls) | No dormant account maintenance charges, no minimum monthly dealing quotas, and zero ledger penalty fees. |
| Transfers Out (ISA / SIPP / GIA) | £0.00 Flat (Free Electronic Exit) | InvestEngine does not charge exit or transfer-out fees to move your portfolio to an external provider. |
| Starting Account Minimum | £100 Minimum Opening Deposit | Initial minimum opening deposit required to activate the account; subsequent regular investments start from just £10. |
*Trades are executed once daily at market prices when the London Stock Exchange is open (orders cut off at 2:00 PM UK time).
The Core Edge: The £0 ISA & SIPP Miracle, Fractional VRP Savings Plans & The Uninvested Cash Retention Model
InvestEngine represents a structural deflationary shock to the UK wealth management industry, stripping out centuries of legacy fees through three operational pillars:
The primary differentiator is **genuine £0 platform economics on registered tax wrappers**. In the UK, traditional investment platforms use percentage custody fees: Hargreaves Lansdown charges 0.45%, Fidelity Personal Investing charges 0.35%, and Vanguard Investor UK charges 0.15% (up to £250k). On a £100,000 portfolio, an investor at Hargreaves Lansdown surrenders £450 every year just for the platform to hold the assets. **InvestEngine charges £0.00 platform fees across GIAs, Stocks & Shares ISAs, and SIPPs**. Every penny of your capital remains invested in your chosen ETFs, saving self-directed accumulators thousands of pounds in cumulative compounding drag over a 20-year horizon.
Second, their **Variable Recurring Payment (VRP) automated savings plans** make dollar-cost averaging completely frictionless. Utilizing UK Open Banking APIs, investors can set up weekly, fortnightly, or monthly automated transfers from as little as **£10**. Unlike traditional Direct Debits that take three to five banking days to clear, VRP transfers sweep into your account instantly and are automatically divided across your target ETF allocation down to fractional pennies. If your portfolio targets 70% Global Equities (VWRP) and 30% UK Gilts (VGOV), a £50 weekly deposit is mathematically split to the penny with **AutoInvest and dynamic rebalancing**.
Third, the transparency of their **uninvested cash retention monetization model**. Many "free" brokers quietly monetize through aggressive payment for order flow (banned by the FCA) or wide hidden FX spreads. InvestEngine is completely open about how they keep DIY accounts free: **they retain the central bank interest generated on uninvested cash held within the portfolio**. For a passive investor whose funds are 99% deployed into working ETFs, this fee model is overwhelmingly advantageous: the broker makes practically zero money off your deployed equity, while you enjoy an institutional platform with zero account maintenance drag.

Valerie's Final Verdict
"InvestEngine is the absolute gold standard for passive, long-term ETF accumulators in the United Kingdom. If your strategy consists of buying broad-market index trackers (like Vanguard's FTSE All-World VWRP or S&P 500 VUSA) and holding them inside an ISA or SIPP for decades, staying on a percentage-fee platform like Hargreaves Lansdown or Vanguard UK is mathematically irrational. InvestEngine gives you the exact same institutional ETFs with **zero platform fees, zero dealing commissions, and zero wrapper charges**. However, you must respect the broker's specific lane: this is a passive compounding workbench, not a trading desk. If you want to buy individual FTSE or Wall Street shares, you will need a companion broker like Freetrade or Trading 212; and because InvestEngine retains 100% of the interest on idle cash balances, **never leave large uninvested cash reserves sitting in your account**—keep your capital fully deployed into working ETFs to ensure you extract maximum value from their £0 platform."
