The food bank team estimates it will provide more than 45,000 meals to people in the city between 13 November and 15 January.
Clay says that with cold weather and pressure on spending, Christmas is “more difficult” than the rest of the year.
“Budgets are tighter, more has to be spent on fuel and energy,” he said.
“So people are contacting us all the time for emergency support and we need to make sure that the support is always there and is continuing to be there.”
Donations are used to purchase emergency hampers, treats or provide advice and assistance.
While the food bank’s doors close on Christmas Day, meals they have provided mean more people can enjoy the festivities.
Every pound donated, up to the first £15,000, would be doubled as part of a match-funding commitment.
