About This Service

A National Insurance (NI) number is essential for working in the UK, claiming benefits, and accessing many government services.

We ensure your application is accurate and complete to avoid unnecessary delays.

Frequently Asked Questions

Who is eligible to apply for a UK NI number?

You can apply for a UK NI number if you have the right to work or claim benefits in the UK. This includes UK citizens, EU/EEA nationals, and non-EEA nationals with the appropriate visa or leave to remain. We'll confirm your eligibility during the consultation.

Can I start working before I receive my NI number?

Yes — you can start working while you wait for your NI number to be issued. You should inform your employer that your NI number application is in progress. Your employer can still pay you and operate PAYE before your NI number arrives.

How long does it take to receive a NI number?

HMRC typically issues NI numbers within 2–4 weeks of a successful application. Processing times can vary. We monitor progress and follow up if there are any delays or requests for additional information.
