Tesco’s partnership with Diabetes UK has raised £18.6m for the charity in less than two years.
The retailer said the money, which was raised by Tesco employees, suppliers and customers between March 2013 and December 2014, is the largest amount raised by a Tesco charity partnership in the UK.
The supermarket chain said that £11.5m was raised by staff fundraising activities, national charity collections and customer donations; £6.1m was raised through head office and distribution centre fundraising activities and corporate donations from the retailer; and £1m was raised through supplier support in the form of promotions.
The original fundraising target was £18m.
The charity said the funds would be allocated to research, education and awareness programmes to improve the lives of people with diabetes and those at risk of developing type 2 diabetes.
The relationship between the supermarket and the charity will continue after the retailer announced in September a new partnership between the two organisations and the British Heart Foundation, which is designed to fund a series of initiatives to help people reduce their risk of developing type 2 diabetes and cardiovascular disease.
Tesco said in a statement this week that the new partnership would last until three years from January 2015 and would have a fundraising target of £30m. The charities will each receive half of the proceeds.
Paul Amadi, director of fundraising at Diabetes UK, said in a statement: "Raising £18.6m is an incredible achievement and far beyond our expectations when we began working with Tesco. This is a real testament to Tesco colleagues, customers and suppliers’ enthusiasm and dedication to fundraising for Diabetes UK.
"The partnership will also leave a lasting legacy, because the funds raised will continue to offer support across the UK for months and years to come, not to mention that it will fund vital research that could transform people’s lives."
Diabetes UK had an income of £38.8m and an expenditure of £33.5 according to accounts filed with the Charity Commission in December 2013.
