The conviction of two Castleisland brothers was the first case of cooperation between UK and Irish authorities investigating tradesmen scams.
Michael and Richard Coffey conned 19 victims out of £45,000 while carrying out roof and other repair works in England.
Michael, who's 29, was sentenced to 26 months, while 25-year-old Richard was jailed for 18 months.
Michael Coffey was in Cork prison during the investigation, and was extradited after completing that sentence; this case was the first conviction in the UK by Trading Standards that involved extradition.
Councillor Nicola Beech, who's a Cabinet Member with responsibility for Trading Standards at Bristol City Council, says it was the first time Irish and British authorities worked together on this type of consumer fraud case.
