Sales of Nisa’s own label range have soared by more than 100% year on year.
The group attributed the sales growth - up 112% on the same period last year (7-21 June) - to the range featuring prominently on the consumer leaflet.
Sales of Heritage Strawberries have grown 75%, while Heritage Jumbo Sausage Roll has quadrupled in sales and Heritage Cooked Ham has doubled in sales.
Heritage brand manager, Erin May, said: “We are overwhelmed with the strong performance of Heritage and we will continue to drive it forward so the brand is at the forefront of consumers’ minds.
“The all-new-look Heritage range is not only delicious but beautiful too with vibrant stand-out packaging.
“It’s a really exciting time for Heritage and we cannot wait to see it develop even further with range extensions which we are currently working on particularly in the chill range.”
The new look range will be fully complete after the transformation of the final 260 delicious products.
