Suffolk Trading Standards said it received a report that ‘Nottingham Knockers’ were operating in the Holbrook area today and has urged residents to report them.

The organisation says they may now have moved on but is urging people to make family, friends and neighbours aware.

A post on the Suffolk Trading Standards Facebook page said: “These individuals knock at doors and claim to be ex-convicts attempting to mend their ways, before trying to sell the householder everyday household products at very high prices.

“Trading Standards advise residents to refrain from buying at the doorstep and not to buckle to pressure from salespeople offering supposedly one-off ‘buy it now’ low prices.

“These Nottingham Knockers work in groups across the country but they are not involved in any officially recognised offender rehabilitation programme and many do not possess Pedlar’s Certificates, which are issued by police and are necessary for salespeople to be legally allowed to sell door-to-door.

“If you are approached at the door, please refuse to buy and then report them to us on 03454 040506 or to Suffolk Constabulary Official Page on 101.”
