During its biggest day in the run-up to Christmas, the online grocer said sales climbed 15% on last year, to almost £6m.
Tim Steiner, chief executive officer of Ocado, said: “We continued the solid growth performance from Quarter 4 into the run-up to Christmas.
“Our focus remained on delivering the highest service levels at this very important time for customers, while offering the widest range at competitive prices.”
The firm also delivered products supplied by Waitrose, which enjoyed a record Christmas this year.
The business’ preliminary results announcement will be made on 3 February 2015.
