If you don’t have a National Insurance number, Hillingdon says they’ll contact you for more evidence when you register to vote. For council tax reduction, you can still apply — the council says to find out how to apply for a National Insurance number on the government website if you or your partner don’t have one.

If you’re asking about voting, the key point is that not having the number doesn’t stop the process straight away — it just means the council will ask for extra proof.
