A data clean-up at Cancer Research UK, the largest research organisation of its kind in the world, could free up thousands of pounds in extra savings.
Data cleansing specialist GB Groups will use the National Register database on UK households and businesses to update the charity's database of 1.5 million supporters.
The data clean-up will remove 'gone-aways' and deceased individuals from the database, and Cancer Research says it will save "a significant amount" in direct-mail costs. One source said this could amount to "at least tens of thousands of pounds".
"Our annual scientific spend is raised almost entirely through public donations - as we rely overwhelmingly on goodwill in a highly competitive marketplace," said head of database at the charity, Michael Toothill.
"As a result of GB Group's work, we will be able to reduce direct-mail costs and use accurate data to raise further donations this year."
