Do you still have any old UK £20 or £50 notes?
The government is urging residents to check if they have the paper notes before they're taken out of circulation in September.
Anyone with them is advised to pay them into the bank or exchanged for the newer plastic notes, which have been introduced over the last two years.
Isle of Man Bank will still accept the discontinued notes after the deadline and send them to the UK, with most other Island banks expected to do the same.
