You may need to fill in this form if you’ve asked for a U1, E301 certificate or a full statement of your National Insurance record. If we need some additional information from you, fill in this form on-screen, then print and post to us.

If you’re applying for a portable document U1 or form E301, send us a letter from your former employer confirming the reason you left the job and also showing their full contact details including:
