The Greggs range is currently being trialled in a Scunthorpe Spar site, with plans to open in Leegomery and Louth later this year.
The Scunthorpe site features a smaller range than what is offered in high street chains, and is focused on Gregg’s top selling products.
It has also seen the introduction of a breakfast bar seating offering, to appeal to nearby student customers.
Greggs franchise team ran a four-week training programme for store staff to enable them to manage the offering.
Martin Kibler, Greggs’ business development and property director said: "We are delighted to team up with Blakemore Retail for this trial, which is in keeping with our strategic plan focusing on growth in the food-on the go market, where convenience for customers is key to success.
“Blakemore Retail is an excellent operator in the convenience sector and I hope this will be the beginning of a long and successful relationship."
Matt Teague, Blakemore fresh food development manager told British Baker’s sister publication Convenience Store: “The company’s franchise partnership with Subway has shown us that the Spar brand can benefit from trading with other strong brands. It is hoped that the well-recognised Greggs brand will add value to the Spar brand, giving existing and new customers a further reason to shop in Spar stores.”
