Next time you request help please consult the database first and provide as much information  as you possible can (what it is for, address, etc.).

Apart from the 0870 number you already have the Pets Helpline can also be contacted by email and fax:

pets.helpline@defra.gsi.gov.uk
fax: 020 7904 6206

In addition, the DEFRA 0845 general helpline (customer contact line) has a geographic equivalent noted in the database of this site. It is: 020 7238 6951. If you must speak with them call this number and ask to be transferred to the Pets Helpline unless of course they can answer your question.
