The Collective Investment Schemes (Amendment etc.) (EU Exit) Regulations 2019 make amendments to retained EU law related to Undertakings for Collective Investment in Transferable Securities (UCITS; see Directive 2009/65/EC). Restriction is in line with the UK’s overarching approach where UK authorised funds must have a depository that is established (had a registered office) and has a place of business in the UK. Prior to the UK’s exit from the EU, it was possible for eligible EEA firms to establish a branch in the UK, then receive a top-up permission to carry out depositary services in the UK. After exit-day, this position was changed such that EU/EEA firms are treated the same as all other third-country firms. As such, from the entry into force on 31.12.2020 of the amendments laid out in the 2019 regulations, depending on the legal form of the fund, the depositary, trustee, operator and/or manager of a UK authorised fund must be a body corporate incorporated in the UK. However, a transitional arrangement was provided for to minimise disruption for firms carrying out this business. The transitional arrangement allows branches of EU/EEA firms to obtain temporary permissions to continue to operate in the UK. By virtue of the EEA Passport Rights (Amendment, etc., and Transitional Provisions) (EU Exit) Regulations 2018, the duration of the temporary permission would be, in principle, three years from the end of the Brexit transition period on 31.12.2020.
