Online trader Andrew Weeks was sentenced at Warwick Crown Court for offences under the Fraud Act.
Weeks was caught following an investigation by Warwickshire County Council Trading Standards.
Officers discovered that he was manufacturing construction industry skill cards at his printing firm and selling them via his website.
Weeks was sentenced to 3 years and 8 months after pleading guilty to the manufacture of fake documents.
The investigation was supported with information from the Construction Industry Training Board and a number of card schemes including the Construction Skills Certification Scheme and the Electrotechnical Certification Scheme.
Graham Wren, Chief Executive at CSCS said: “This is another example of the industry working together to tackle card fraud.
“CSCS will always support the authorities to identify and act against those attempting to deceive construction employers.
“This case also highlights the need for thorough card checks, ideally electronically, to ensure construction workers are who they say they are and have the correct qualifications for the job they do on site.”
Weeks was also sued by CSCS for copyright infringement and ordered to pay damages of £6,000.
Steve Brawley, Chief Executive at ECS said: “We hope that this case will serve as a message to would be fraudsters that their actions will not be accepted.
“Fraudsters on construction sites present a danger to themselves and others and we need to work together to stamp this activity out.”
Ian Sidney, Fraud Manager at CITB said: “This sentence shows just how serious construction card fraud is and the lengths that CITB and the whole industry will go to in order to stamp it out.
“The use of fake cards could easily lead to accidents, injuries or even fatalities where contractors do not have the required skills, training or qualifications.
“Employers must remain vigilant when checking workers’ documentation and keep an eye out for any suspicious activity.”
