Kenneth Hornsby was sentenced to three years in prison in 2003 after an investigation revealed he had carried out bogus repairs in Northamptonshire, Buckinghamshire and Oxfordshire.
Now, after a five-year investigation by Trading Standards, he has had a substantial chunk of his assets seized.
David Hedger, assistant head of Northamptonshire Trading Standards said the ‘repairs’ could have been disastrous for retailers.
“If chilled products were not being stored at the correct temperature this could have been a real danger to consumer health,” he said.
Hornsby also altered the wiring in a number of the appliances that he pretended to fix.
Trading Standards found that one fridge had been so dangerously tampered with that it could have delivered a life-threatening electric shock.
