James Hall & Co is the Spar wholesaler for the north of England, supplying more than 600 stores, and also owns an estate of 113 convenience stores and 29 filling stations.
Managing director Andrew Hall said: "Over the years we've built a very strong relationship with Chris Cave, our area manager, and Valero. This is a really important relationship for us, and a key factor in our decision to extend our agreement with Valero was having a strong brand like Texaco on our forecourts. Their reliable supply network means our customers can depend on us to meet their needs."
Andrew Cox, Valero's director of sales and marketing, said: "We're delighted that James Hall & Co have extended their agreement with us and it's great to hear that the redevelopment of Threshfield is under way. Our strong relationship with them, which we've built over the years, is something we're proud of, so we're very happy they've chosen us as fuel supplier for their new site."
The latest development, Threshfield, near Skipton, was purchased in 2015.
