Can I change old notes / coins for new ones?
Yes, as a NatWest customer you can swap, or deposit into your account, out of circulation coins/notes and replace them with new ones.
All Royal Bank of Scotland and Ulster banknotes (as with all Scottish and Northern Irish banknotes) remain legal currency, will not be withdrawn from circulation in the same way as the Bank of England notes, and have no end date for acceptance.
You are unable to swap / deposit commemorative coins.
