Can you help determine whether my business needs to be authorised?

Yes, we work with many businesses who seek advice on whether they require authorisation by the FCA or the PRA. We can often help firms identify exemptions from the need for authorisation or provide advice on how they can change their business model to avoid the need for authorisation. We also advise on whether arrangements may constitute a Collective Investment Scheme (and/or an Alternative Investment Fund) which would require an FCA authorised operator (and/or AIFM).

Yes, we can help you apply for FCA or PRA authorisation and/or to register your crypto-exchange with the FCA.

Can you work with other law firms?
