The NSPCC has struck a deal with home-moving portal ihavemoved.com that will see £1 donated to the charity for every new user.
Ihavemoved.com will give £1 to the NSPCC when a new customer uses the site to notify two organisations of their new address details. The initiative is expected to raise about £35,000 a year.
The NSPCC is promoting the scheme with a direct-mail campaign to its 350,00-strong donor base. Members are also being encouraged to pass the information on to friends and family who may be moving house.
"All big charities find it difficult to keep in touch with their donor database,
said David Chernick, head of new-business development at ihavemoved.com.
"Eleven per cent of the population moves house every year, so this service will not only generate funds for the NSPCC but will also help charities stay in touch with their supporters,
The portal launched a similar scheme with homelessness charity Shelter in November 2001. Students were asked to register their address changes on ihavemoved.com, which triggered a 50p donation to the charity.
