"There has been rapid growth in the provision of foodbanks since hunger in the UK became a prominent issue after the financial crisis, and austerity that followed it from late 2010. Almost all UK food banks are co-ordinated by The Trussell Trust, a Christian charity based in Salisbury which serves as the UK's only food bank network. In 2004 Trussell only ran two food banks.[35][36] Before the financial crisis, food banks were "almost unheard of" in the UK.[37][38] In 2007 / 2008 there were only 22 food banks in the Trussell Trust Foodbank Network; by early 2011, The Trussell Trust supported 100. As of May 2012, they had 201. By August, 252. The rate of increase has been rising rapidly. In 2011, only about one new food bank was being opened per week. In early 2012, about two were being opened each week. By July, The Trussell Trust had reported that the rate of new openings had increased to three per week. In August, the rate of new openings spiked at four per week, with three new food banks being opened in that month for Nottingham alone."

2008 22 food banks; 2013 250 or so. What been the major change in those years? Oh yes, Austerity measures and a coalition government that has made some significant changes to the benefits system. We should definitely attempt to determine exactly what is the cause of this. It seems very unlikely that these 2 events are unconnected.
