Check the see-through window

A genuine polymer £5 note should have a large see-through window with a clear portrait of the Queen printed on it and the words '£5 Bank of England' printed twice around the edge.

Look for Big Ben

There should also be a metallic image of the Elizabeth Tower (aka Big Ben) on the see-through window.

The foil should be gold on the front and silver on the back of the note. When the note is tilted a multi-coloured rainbow should be visible.

Look for the three foil patches

There should be three foil patches on a genuine polymer fiver.

On the front of the note below the see-through window there should be a silver foil patch with the word 'Five'. When tilted the patch should change to read 'Pounds'.

There's another silver foil patch above the see-through window containing the image of the coronation crown which appears in 3D. When titled the image produces a multi-coloured rainbow effect.

A real £5 note should also have a circular green foil patch on the back which contains the words 'BLENHEIM'. This should be located directly behind the crown on the front.

Check for the ultra-violet five

A real polymer £5 will also have a number '5' that you can only see under ultra-violet light.

The number should appear in bright red and green, while the background should remain dull in contrast.
