Director of the Shindig Festival in Wiltshire, Simon Clarke, said planning the 2026 event was “not easy” as fuel prices were changing almost daily.
Like many others, the event uses diesel generators to power production, sound systems, lighting and food stalls.
Clarke said Shindig usually buys about 12,000 to 15,000 litres of diesel, which already costs tens of thousands of pounds.
“Because our event is in several weeks, it’s too difficult for us to swap [to another fuel source], so we’re stuck with diesel,” he said.
“We can’t change the plans that much, I’m afraid.”
The festival will run from 21 May to 24 May at Charlton Park, near Malmesbury.
Despite higher running costs, Clarke said organisers were “very guarded” about protecting ticket prices.
“To put the ticket price up to the customer wouldn’t be an option to us.
“I think the main thing we’re working on is selling more tickets,” he said.
