The Fundraising Regulator has changed its policy and will now name all organisations that have been investigated when it publishes the report, the regulator has announced.
It said the new approach is intended to bring more transparency to the process and will make it clear whether complaints have been upheld or not.
The new policy will apply to complaints received from 1 March 2019. People who make a complaint will continue to remain anonymous.
The regulator said it will continue to share its findings with organisations ahead of publishing them, to allow them to prepare reaction.
Gerald Oppenheim, chief executive of the Fundraising Regulator, said: “A transparent approach means donors can fully consider who they wish to donate to. When we publish our decisions, we will clearly recognise the organisations that have cooperated fully with our investigations and used it as an opportunity to reflect on how they carry out their fundraising efforts.
“We are confident that the change in the way we approach investigations will encourage organisations to scrutinise their fundraising efforts more closely to ensure they meet the standards required of them.”
