All contestants had to nominate a charity before appearing on the programme.
A percentage of total profits on telephone calls made by the public voting for their favourite contestant is to be shared between them.
The Chemical Dependency Centre in London and the Psoriasis Association were both nominated, along with more well-known charities including the NSPCC and Cancer Research UK. Winner Tony Blackburn chose The National Autistic Society as his charity.
The organisations nominated were still waiting to hear how much money they would get as Third Sector went to press.
A total of 15p from each telephone call and between 1.8p and 6.7p for each text message went to charity.
