Tesco will launch a major revamp of its entire frozen food range tomorrow (26 September).

Hundreds of new frozen products will be rolled out across its UK stores, in the latest move in the retailer’s £1bn turnaround plan. The move includes the debut of 54 new products in its Everyday Value line-up, which recently replaced the long-running Value budget line.

“This is the first major relaunch of our frozen food in five years,” said chief executive Philip Clarke.

He said the investment was further evidence of Tesco turning the corner in the quality of its food offering, having brought in 1,800 new products and improved a further 1,850 in the past six months.

“It involves many of our own label items and brands,” Clarke said. “The frozen food manufacturers are particularly innovative.”

The revamped range includes new 150ml versions of Tesco’s venture brand ChokaBlok ice cream, as well as relaunched products from Birds Eye and Young’s.

The announcement comes a week ahead of a crucial set of results for the supermarket giant, following its unprecedented profit warning earlier in the year.

Clarke said his turnaround plan was beginning to pay dividends, with Tesco claiming it had received a “tremendous” reaction from customers to its new products, investment in extra staff and changes in-store.

Tesco supermarkets across the UK will be given re-designed meat sections in in the next two weeks, including sloped shelves to better show off meat products. In total, the retailers is trialling 150 different new projects in its stores, before deciding whether to roll them out nationally, including patisserie sections and fresh pizza.

“We have a long, long way to go but we are beginning to see the results of our £1bn investment,” declared Clarke, who said the £200m spent on additional staff meant its stores were no longer “running hot”.

“In the last six months we’ve added 300,000 more hours per week, with 8,000 new full time employees,” he said.
