How to check you £5 polymer banknote?

There are a number of ways to verify and check a £5 polymer note to determine if it is a genuine banknote.

Ask yourself these questions? Remember, do not rely on one feature.

  1. Does it feel like plastic? The newer banknotes are printed on a special thin polymer, which is a light flexible plastic.

  2. Can you see the portrait of Queen Elizabeth? You should be able to see the portrait of Queen Elizabeth through the see-through window, around the portrait should be the words ‘£5 Bank of England’ printed twice around the edge.

  3. Have you checked the metallic image of the Elizabeth Tower aka Big Ben on the see-through window?
  1. Is Big Ben gold on the front?

    2.Is Big Ben silver on the back?

  • Have you checked the three foil patches? There are three foil patches on a genuine polymer fiver:-

    1. On the front below the see-through window, there should be a silver foil patch with the word ‘Five’. When titled the patch changes to the word ‘Pounds
    2. Above the see-through window on the front, there is an image of the coronation crown which appears in 3D. When titled the image produces a multi-coloured rainbow effect.
    3. Check the green foil patch contains the word “Blenheim”. Located on the circular green foil patch. Images are taken from Bank of England

  • Can you see a “5” when under an ultra-violet light?  The “5” appears on the bottom left of the note and appears bright red and green when under UV light.

What Doesn’t work

  • Detector Pens

    Unfortunately, detector pens that are used for older notes cannot be used to detect counterfeit. Detector pens work by a chemical reaction between the ink and the paper, however with newer polymer notes using a plastic material the ink simply rubs off.

  • Ultra-violet (UV) Lamp

    For polymer notes, you will have to ensure the UV Lamp emits light at around 365 nanometres. Use of Light Emitting Diode device like a key fob is not recommended as these tend to emit light greater than 365 nanometers.

    Recommend UV Lights
