The New Gift Aid charity consortium plans to enable donors to process gift aid donations via a telephone helpline when it rolls out its annual campaign in November.
Launched in 2000, the consortium is an annual collaboration of leading charities that pool their databases to communicate with mutual supporters and asks them to make a single New Gift Aid Declaration.
It is also exploring the development of an online service to let people process their declaration response online.
The changes follow research conducted by Pell %26 Bales, one of the agencies working with the consortium, which investigated why people failed to respond to the original mailing. The research identified confusion about eligibility for the scheme, and the 2002 campaign aims to make it simpler for supporters to respond.
"Charity fundraisers must take advantage of New Gift Aid in order to grow their organisations' income base,
said chief executive of Pell %26 Bales, Karl Holweger.
Since its formation, 26 charities have participated in the consortium, raising an estimated £2 million in additional revenue.
