Don't forget the deadline for using the old paper £10 note is 1st March 2018, try not to let too many moths escape while hunting for them.

Just read somewhere online that you can always exchange old out of circulation paper notes by post directly to the Bank Of England ? Is that true I wonder , I thought that if you missed the deadline to spend, and once the banks had allowed you a few more weeks to pass them in , that that was that .

Yes, unlike coins, banknotes are a warrant issued by the relevant bank and so cannot expire despite no longer being legal tender.
