What is Fund Supermarket?
An online investment platform that lets you buy, hold and switch between funds from many providers in one account, often within an ISA or pension wrapper.
Full Definition
A fund supermarket is an online platform that brings together funds (and often shares, ETFs and investment trusts) from a wide range of managers, letting you hold them in a single account. In the UK these platforms typically offer tax wrappers such as a Stocks and Shares ISA, with its GBP 20,000 annual allowance for 2026/27, or a Self-Invested Personal Pension, where the annual allowance is GBP 60,000. You pay a platform charge (often a percentage of assets) on top of each fund's own ongoing charge. The appeal is convenience and choice: you can compare, buy, switch and consolidate holdings without dealing with each fund house separately, and view everything in one place. Costs matter because layered fees compound and erode returns over time, so it is worth comparing platform pricing, especially for larger portfolios where a flat fee may beat a percentage charge. Investments can fall as well as rise, so a fund supermarket carries normal market risk.
