You can enter Great Britain with a Great Britain pet health certificate from any country.
Ask your vet if they can complete the certificate for you.
The certificate must be signed, stamped and dated by an official veterinarian (OV) who has authority from their government to issue it.
If your vet is not an OV they need to contact their local authority to get the certificate signed, stamped and dated.
Your pet must enter Great Britain within 10 days of the pet health certificate being issued.
