Tesco, Diabetes UK and the British Heart Foundation have announced a £30m fundraising target for their joint campaign to reduce the risk of type 2 diabetes and heart disease.

The partnership between the three organisations was announced last year. It aims to reach this target over three years, having already raised £2.5m and attracted 4,500 fundraising volunteers.

Money will be raised by Tesco staff and volunteers from the two charities through in-store events and collections.

From September 2015 the money raised will be spent on community projects affecting 40,000 families in the areas most at risk Type 2 diabetes and heart disease, as well as encouraging 500,000 families to take part in physical activities in a wider awareness drive.

A spokeswoman for Tesco said this is a “ground-breaking charity partnership” as it “aims to build a lasting legacy and has already working with local councils and community organisations across the UK to help them to tackle two of the most serious health threats in the UK today”.

The partnership between Tesco and Diabetes UK has had previous success. Diabetes UK raised £18.9m from the partnership between March 2013 and December 2014.

Josh Hardie, the corporate responsibility director for Tesco has previously described the partnership as “our most successful partnership ever”.

Tesco has announced other charity partnerships for 2015 with the Children’s Food Trust and FareShare. It has recently launched an app to promote the distribution of store food surpluses.
