Subway operates as a franchise model, meaning that all its stores are independently owned and operated by franchisees. The company said that low start-up costs make it an "ideal entry point for entrepreneurs".
Mike Charest, Subway’s assistant regional director for Europe said: "The UK and Irish markets have been fantastic success stories for the Subway brand and we see opportunities for further growth as more and more consumers demand great tasting food at a value price-point.

Subway actively markets its food as a healthier, more nutritious alternative to other fast foods. The brand is a partner in the UK government’s Public Health Responsibility Deal and said it was the only quick-service restaurant to have endorsed six nutrition-related pledges.
Accordingly, the Subway Real Deal includes five options from its low-fat range; and last year it launched a healthier Kids' Pak.
