Do local authorities have to check that an applicant has permits or licences issued by their home country before they can apply for a licence or permit in the UK?
Not in general. You must treat applications from another member state in the same manner as you would approach an application from the UK, so you must only ask about qualifications and experience for applications from service providers from other Member States on the same basis as for those from the UK. You should also note that a start up without any trading history can apply from another member state.
