Hi lucy Andrews,
Unfortunately there is no other option to obtain a A1 certificate.
• Their employer or agent must fill in form
CA3822 ‘Application for a certificate of continuing liability’
• their employer must fill in form
CA3821 if it is the first time they need an A1 certificate.
• that even if they have been abroad for a long time they may still need to provide a A1 to the local authorities.
• if their agent fills in form CA3822 they must have an agent authority form 64-8 in place to act on their behalf
• they can download the forms from our website www.gov.uk
Thank you.
