Crystal Mark
The Crystal Mark is our seal of approval for the clarity of printed and online documents. Launched in 1990, and the first mark of its kind, it now appears on tens of thousands of documents in the UK and other countries.
You can view our list of organisations which currently have at least one Crystal Mark.
Unless you are a corporate member, there is usually a small fee for each Crystal Mark.
The Crystal Mark fee does not include the cost of any editing that may be required. It does, however, cover the cost of us checking future revisions to the document.
If you have a document you want a Crystal Mark for, just email it to us at info@plainenglish.co.uk.
