Since the Financial Services Act came into force in April 1988, anyone engaging in 'investment business' as defined by the act commits a criminal offence if not authorised. Although real property is not an investment under the act, the need for authorisation may arise if there is a financial instrument linked to the property, such as an endowment pension-linked mortgage, or if there is a pooling arrangement for the ownership of property, such as through a bond or unit trust, ie. a collective investment scheme. There are a variety of different routes to authorisation depending upon the amount of investment business being undertaken. Firms should approach the Financial Conduct Authority.
If you hold information in relation to individuals for the purposes of a UK business, you are likely to have to comply with the UK data protection regime set out in the Data Protection Act 2018, along with the General Data Protection Regulation (which also forms part of UK law). In addition, organisations and sole traders holding information in relation to individuals may need to pay a data protection fee to the Information Commissioner's Office. Information and advice can be obtained from the Information Commissioner's Office.
