Businesses in South Gwynedd are being urged to stay vigilant after a number of counterfeit bank notes were reported in Pwllheli.
North Wales Police say they are investigating five incidents on March 17 where suspected fake £20 notes — all carrying the same serial number — were used in local shops and businesses.
Officers are now working to trace those responsible and prevent further losses, with particular concern for small independent traders who are often hardest hit by this type of crime.
Unlike larger retailers, small businesses are less likely to have specialist equipment to detect counterfeit notes, meaning they can be left out of pocket if a fake slips through. Once a counterfeit note is accepted, it cannot be reimbursed, leaving shop owners to absorb the loss themselves — something that can quickly add up, especially in busy tourist areas like Pwllheli.
Police say this type of activity can often increase as footfall rises, making it even more important for businesses across North Wales to remain alert.
The Bank of England is reminding retailers to check notes carefully using a few simple steps. Genuine notes should have a distinctive feel, a clear hologram and a visible metallic thread. Any note that raises suspicion should be refused.
Counterfeit currency remains a persistent issue across the UK, with increasingly sophisticated techniques sometimes making fake notes harder to spot at a glance. However, officials say regularly checking notes — particularly higher-value ones like £20s — remains one of the most effective ways to reduce risk.
Police are asking anyone who may have information about the incidents in Pwllheli to come forward by calling 101 and quoting the reference number provided.
As investigations continue, the message to businesses is clear: stay cautious, check every note, and report anything suspicious — helping to protect both livelihoods and the wider local economy.
