I've required my passport a lot recently when selling/buying property. The lawyers needed it for proof of identification for money laundering purposes and the Bank needed 2 forms of identification., (not including a bus pass!). I used my driving licence as well as NI information. I would always keep a passport up to date even if I had no reason to travel abroad.
Have you stopped buying papers?
