The Crystal Mark logo

This section of the site tells you how to apply for the Crystal Mark and gives guidelines on what we look for. There is also information about  the Honesty Mark, the Internet Crystal Mark, and the 'Approved by' logo. For information about the corporate membership logo and benefits, please visit the corporate membership section.

The Crystal Mark is our seal of approval for the clarity of a document. It now appears on over 21,000 different documents in the UK, the USA, Australia, Denmark, New Zealand and South Africa. It is the only internationally-recognised mark of its kind.

Launched in 1990, the Crystal Mark has now become firmly established as the standard organisations aim for if they want to provide the clearest possible public information.

There is a fee for the Crystal Mark unless you are a corporate member. The fee for the Crystal Mark is normally £500 + VAT. However, we may be able to group a number of documents together so you only pay the fee once. Or, if you only have one small document, we will reduce this fee to £200 + VAT.

The Crystal Mark fee allows us to edit any subsequent minor changes to any Crystal Marked document, free of charge. This way you don't have to worry about any ongoing editing charges as you make minor alterations.

We provide a separate Crystal Mark for each document we approve. Each Crystal Mark has its own identification number. This helps us to identify your document if we are contacted by a member of the public.

You can view a list of organisations who currently have a Crystal Mark on one or more of their documents.

For information about our editing and testing services please go to the Editing services section.

    Approved by logo

    This is our seal of approval for communications where the Crystal Mark process is not practical. These include constantly-changing documents such as magazines, newsletters or long instruction manuals.

    When we assess these materials, we carry out checks which are similar to those we do with the Crystal Mark. We are looking for clear layout and design, and language appropriate for the intended audience. There is a charge of £200 + VAT for this assessment. There is then an annual charge for display of the logo, which depends upon the size of the publication.

    With magazines we ask to see three issues before we can approve them, and we then see each issue as it is published. We discuss any problems with the editorial staff.

  • Honesty Mark

    Every customer survey shows that one of the most important things to buyers is trust. Plain English can help give consumers an informed choice, but we need all the facts at our fingertips.

    The Honesty Mark logo

    Our solution is the Honesty Mark. This is a free logo available to any document displaying a Crystal Mark, so long as the organisation is prepared to sign our declaration. This declaration guarantees that everything in the document is true and complete. In other words, what you see is what you get.

    For printed and online publications

    Your book could carry the accreditation of a ‘Plain English Book Mark’. This accreditation tells the reader that the book’s clarity has been independently assessed by an expert.

    The Book Mark is our seal of approval for publications that are not suitable for our Crystal Mark. These publications include non-fiction books, training manuals or published reference materials that are either printed or available online.

    When we assess these materials, our editors carry out checks which are similar to those we do for the Crystal Mark. However, we don’t expect the copy to be written to Crystal Mark standard.

    We are looking for clear layout and design, and language that is appropriate for the intended audience.

    We will review the publication and discuss the assessment with you. We will also suggest changes you could make to qualify for the accreditation.

    There is a charge for the assessment, review and accreditation. The charge will depend on the size of the publication. We can give you an accurate estimate if you can provide a final draft, but the full accreditation could be available from just £500 + VAT.

    Final drafts or reprints which meet the assessment criteria can display the ‘Book Mark’ logo until any updates or changes are made. At this stage, you would need to make a new application.

    What we assess

    We look at:

    • the text;
    • the design and print quality; and
    • the usefulness to the intended audience.

    The text

    For example, we look at the following.

    • Sentence length
    • Paragraph construction
    • Grammar and punctuation
    • Nominalisations and passive verbs
    • The suitability of the text for the intended audience

    The design

    For example, we look at the following.

    • Typesize and typeface
    • Size of headings and subheadings – is there a clear hierarchy?
    • Use of headings – do they run into each other across articles or pages?
    • Use of white space
    • Does the design make it easy to read?
    • Overprinting
    • Use of reversed-out text
    • Pagination – does it make sense?
    • Print quality

    Usefulness

    • What is the purpose of the book and does it achieve its aim?
    • Is the tone appropriate for the readership?
