A collective investment account is an investment vehicle where multiple investors pool their money together to invest in a range of securities or assets. These investment accounts are managed by a professional fund manager or management team, who are responsible for making investment decisions on behalf of the account holders.

The investments can include stocks, bonds, property, or other assets, and the returns generated by the investments are then distributed among the investors in proportion to their stake in the account. Collective investment accounts can take many different forms, including unit trusts, investment trusts, and open-ended investment companies (OEICs).

These investment vehicles are regulated by the Financial Conduct Authority (FCA) in the UK to protect investors and ensure that they are managed in accordance with the relevant rules and regulations. Collective investment accounts can be a popular way for individuals to gain exposure to a diversified portfolio of investments that they might not otherwise have access to or be able to afford on their own.
