On the hottest day of the year, four homes were completely burnt to the ground - and another two were partially destroyed - on Woodland Drive in Kingstone.
The cause of the fire has been deemed to be accidental, starting in a garden shed and was of electrical origin.
Barnsley Trades Club, based on nearby Racecommon Road, will be hosting a fundraising event on August 5, with all proceeds going to help those affected.
Judith Forster, assistant secretary of the club, said: “We are holding a fundraising event to help those affected by the Woodland Drive fire disaster.
“We’ve got a DJ, the Manhattans playing and we’re currently going around businesses asking for donations for a raffle.”
It’s £2 to enter, with kids going in free, and will begin in the evening.
