Sheikh Abid Gulzar opened the new attraction at the start of the week and is charging £1 for an ice cream.
Mr Gulzar, who purchased the pier on June 15, said he has lowered the price as he expects a ‘bumper weekend’ during the rising temperatures.
He said: “I am keen to get new attractions onto the pier as soon as possible.
“It’s summer and I want visitors, both locals and tourists, to have the best possible experience.
“It’s good quality ice cream and what a bargain at just £1.
“The hot weather is back and I am preparing for a bumper weekend.
“Come onto Hastings Pier. We look forward to welcoming everyone.”
Hastings Borough Council said it has not received a listed building planning application for the shed but expects to have it within 30 days.
