Charities need to make sure their fundraising materials and policies are in line with the new version of the Code of Fundraising Practice, which is being launched next week, the Fundraising Regulator has warned.
The new code comes into effect on 1 October, after a revamp that was unveiled in June.
Although the actual content of the code itself has not changed, the document has been restructured and rearranged to make it easier to navigate and to get rid of duplications.
In a statement, the regulator said charities should ensure that all their fundraising materials, training materials and policies are updated to correspond with the new version of the code.
"Complaints will be considered against the version of the code in effect at the time of the incident," the statement said.
"This means the new code will be used as the basis for making decisions about any concerns that take place from 1 October onwards."
The regulator has produced a mapping document and a deletions and mergers log to show where the different rules and sections have been moved to, which will be available online until November, the statement said.
Suzanne McCarthy, chair of the Fundraising Regulator’s standards committee, said: "Since we launched the new code back in June, fundraising organisations should have made significant progress on updating their fundraising materials to reflect the new code.
"By making the code easier to use and more accessible both online and in print, we have made it easier for charities and other fundraising organisations to meet their responsibilities to the public."
