Think of it like a slow-motion heist. The Bank is stealing paper notes from circulation, one by one. They are actively withdrawing them.
Polymer notes are tougher. They survive the washing machine. They survive being sat on. Paper notes? They get soggy and sad.
So, while paper notes are legal, the Bank really, really wants them back. They call it a “withdrawal from circulation.” Fancy, right?
When Does the Clock Run Out?
Here’s the fun, slightly terrifying part. Paper £20 notes have a deadline. The official “demonetisation” date—the day they stop being legal tender—was 30 September 2026.
Wait, what? I just said they were legal! Yes, they were. But after that date, shops can refuse them. The corner shop won’t take them. The pub will laugh.
Don’t panic. The Bank of England is a kind beast. They still exchange old paper notes for new polymer ones. Forever. Or at least, for the foreseeable future.
