Managing director James Stoddart, said: “It could be cheaper and perhaps more convenient for us if we got involved with suppliers from elsewhere in the UK.
“But we have worked with the likes of QFS and Morgan’s Bakery here in Middlesbrough since day one, and despite the fact we have enjoyed growth, that is not something we intend to move away from.
“Over the years, we have built up excellent relationships with local suppliers. It is very personal, you know exactly who you are dealing with and you place a trust in them to get the best deal they possibly can for you.
“Each supplier has its own specialist market, they are continually monitoring costs and keeping us up to date with what is going on.
“It is something I feel very strongly about, and I also feel it is vitally important to keep local money within the local economy.”
The firm was created by James and his wife Helen, and now operates seven days a week with the current 130-strong workforce producing up to 150,000 sandwiches from three production lines each week.
The expansion of the business will also create around 100 new jobs.
