If you´ve worked abroad in a EU country and want to transfer any built- up entitlement to unemployment benefits to another EU country, you need to apply for a U1 form from the UK authorities to present to the authorities here in Spain.
You can do so from the UK, once your contract has ended, and you won´t remain in the UK for longer than 15 days after that, or from Spain online if you´ve got a ´Government Gateway´ account
or by mail
Note: You need to answer the first 2 questions with ´no´. Make sure to have your P45 or P60 handy to be able to copy NI number, PAYE reference number of your employer etc.
Once completed and printed off, include copies of the following documents
If you don´t have any of these documents, or one is missing, you need to include a copy of your P45 form for the last 3 years.
And send to this address
NIC & EO HM Revenue and Customs

United Kingdom
If all documentation is complete, it takes between 1 and 2 months to receive the form. If it takes longer and you want to make enquiries, here is the contact info.
Telephone +44 191 203 7010 from Spain or 0845 915 4811 from the UK. Or fax +44 191 225 9570.
