A "prolific rogue trader" who lured customers in with his "charm and charisma" has been found guilty of 37 counts of fraud.
Mark Killick, who also operated under the aliases Marc Cole and Mark Jenkins, failed to complete building work at properties across the West of England between December 2019 and November 2021.
The 56-year-old, of Shoe Lane in Paulton, Somerset, was found guilty of the 37 counts of fraud and cleared of one at Bristol Crown Court earlier following a three month trial. It is his fourth conviction for fraud since 2008.
The prosecution highlighted Killick's spending on luxury goods, including a £25,000 Rolex watch which he claimed was an asset for the failing business.
The jury failed to reach a verdict on eight further charges against him.
Avon and Somerset Police and Trading Standards received more than 100 complaints against Killick covering a period between 2019 and 2021.
Martyn Nicklin, from Bristol Trading Standards, said Killick offered people their "dream extension" or renovation, which he started but frequently left "completely unfinished".
He described Killick as an "excellent salesperson" who used his "charisma and charm" to defraud people.
"I think he is still one of the most prolific rogue traders that we've ever dealt with, if not the most prolific," he said.
"Certainly the scale, the number of victims, the financial impact; the harm that he's caused is vast," he added.
