InvestEngine Review (2026) – Fees, ISA Features & Pros and Cons

InvestEngine is a UK investment platform founded in 2019 that specialises exclusively in ETFs — exchange-traded funds. Unlike broader platforms that offer individual stocks, funds, and bonds, InvestEngine has built its entire product around ETFs, making it one of the most focused and cost-effective platforms for investors who want low-cost, diversified portfolios.

The platform offers two routes: a DIY portfolio where you choose and manage your own ETFs with a 0% platform fee, or a Managed portfolio where InvestEngine's investment team builds and manages a diversified ETF portfolio on your behalf for 0.25% per year. Both options are available within a Stocks & Shares ISA.

InvestEngine is particularly well suited to investors who understand that most actively managed funds underperform cheap index ETFs over the long term, and who want a straightforward way to invest in a globally diversified portfolio at minimal cost. It is also a strong choice for investors who want automated investing without paying the higher fees of traditional wealth managers.

InvestEngine's Stocks & Shares ISA is available on both the DIY and Managed plans. On the DIY plan, there is no platform fee — you only pay the underlying ETF charges, which typically range from 0.03% to 0.20% per year. This makes it one of the cheapest ISA options available for ETF investors.

On the Managed plan, InvestEngine charges 0.25% per year and builds a diversified portfolio of ETFs matched to your risk profile. This is significantly cheaper than traditional wealth managers or robo-advisors, many of which charge 0.5% to 0.75% or more. Regular contributions can be automated, making it easy to add to your ISA each month.

Fees are one of the most important factors when choosing an ISA platform. Over long periods, even small differences in fees can have a significant impact on your investment returns. Here is a full breakdown of what InvestEngine charges.

InvestEngine gives UK investors access to a range of investment types within its Stocks & Shares ISA. Below are the main asset classes available on the platform.

Security and regulation are critical factors when choosing where to invest your money. Here is how InvestEngine protects your investments.

InvestEngine has a clean, uncluttered interface that is focused entirely on long-term portfolio building rather than active trading. The onboarding process is straightforward — you answer a few questions about your investment goals and risk tolerance, then either choose your own ETFs or let InvestEngine manage a portfolio for you.

The DIY portfolio builder makes it easy to search, compare, and add ETFs to your ISA. Each ETF comes with a clear description of what it tracks, its annual charge, and its historic performance. For newer investors, the Managed option removes all of this decision-making and simply builds an appropriate portfolio automatically.

Regular contribution features allow you to set up automatic monthly deposits into your ISA, making it easy to invest consistently without having to remember to log in each month. The mobile app mirrors the desktop experience and is well-designed for portfolio monitoring on the go.

Opening a Stocks & Shares ISA with InvestEngine is straightforward and typically takes around 10 to 15 minutes.

One of the biggest advantages of investing through a Stocks & Shares ISA is the tax efficiency it provides. In the UK, investments held outside an ISA are subject to Capital Gains Tax (CGT) on profits above the annual allowance of £3,000, and Income Tax on dividends above the £500 dividend allowance. Inside an ISA, both of these taxes are completely eliminated — no matter how much your investments grow.

For long-term investors, this can make a substantial difference over time. For example, an investor who generates £5,000 in gains outside an ISA would pay up to £480 in Capital Gains Tax (at 18% basic rate). Inside an ISA, that same gain is entirely tax-free. The ISA allowance resets every tax year on 6 April, and any unused allowance cannot be carried forward.
