The charge is part of the retailer's plans to be more environmentally friendly. It follows successful trials in over 50 M&S stores in Northern Ireland and the South West of England. The trials saw customers’ use of food carrier bags drop by over 70% and raised over £80,000 for environmental charity Groundwork.
M&S chief executive Sir Stuart Rose said: "This move lies at the heart of our 100-point eco plan, Plan A. We want to make it easy for our customers to do their bit to help the environment and our trials have shown us that they want to take action."
All profits generated from the charge will go to Groundwork and be used to create or improve greener living spaces such as parks and play areas.
