Introduction to Investment Firms

The Central Bank authorises two types of Investment Firms. Information on each type of Investment Firm is available by clicking on the appropriate link below:

• IIA Non-Retail Firms
• MiFID Firms

In determining whether a proposed application falls for authorisation under the IIA or MIFID, applicants are advised to seek legal advice prior to submitting a formal application for authorisation.

Unlike a MiFID investment firm, investment business firms authorised under the IIA can only provide a limited range of services and cannot passport their services to other EEA jurisdictions.

The Central Bank of Ireland’s Registers contains a list of all financial service providers currently regulated by the Central Bank.

Please also see our Overview of Business Processes webpage for further information.
