See our answers to common questions below. If you have any questions not answered here, please feel free to contact us at [email protected]

  • Can I still request a specific editor or subject specialist if I place an express (12-hour) order?

    While we do our best to accommodate any requests for specific editors, it may not always be possible if the order is for a 12-hour express turnaround. However, for orders with deadlines of 24 hours or more, we are almost always able to assign your preferred editor.

  • How can I trust your service/company?

    Cambridge Proofreading has served 77,000+ clients in 110+ countries. We’re registered in the State of Illinois, and you can verify our LLC registration and Certificate of Good Standing by searching for Cambridge Proofreading LLC in the Illinois Department of Business Services database.

    You can also read independent reviews from our clients on TrustPilot.

    We accept payments via PayPal, the internet’s most popular and secure payment gateway, as well as Braintree and Alipay.

    We recommend that you read our blog post about avoiding scam proofreading services and carefully evaluate whom to trust with your documents.

  • Is your website secure?

    Our service is 100% secure and confidential.

    Our website is secured with DigiCert SSL Extended Validation and 256-bit encryption.

    Files uploaded through our website are stored on a password-protected server. Only the editing manager and the assigned editor will have access to your file, and it will never be shared externally with anyone under any circumstances.

  • What is your Quality Guarantee?

    The Cambridge Quality Guarantee covers all orders placed through our website:

    If you are not satisfied with the service you have received and can cite fair justifications, we will issue a partial or full refund or arrange for a re-edit.

    We guarantee that we will significantly improve the language of your documents. Our performance is measured by your satisfaction; if you’re not entirely happy with our work, contact us and we’ll find a suitable resolution.

  • How can I be sure of the quality of your services?

    Remember that you are protected by the Cambridge Quality Guarantee, which states:

    If you’re not satisfied with the service you’ve received and can cite fair justifications, we’ll arrange for a re-edit or issue a partial or full refund.

    If your file is over 20,000 words, you may submit it to us via email (as an attachment), and we will provide a free sample of 500 words within 24 hours.

    You can also view samples of our work here.

  • How do you choose which editor will proofread my document?

    There’s no substitute for subject-matter expertise. With 300+ editing professionals, we have expert editors across the full spectrum of academic disciplines. This broad base of knowledge allows us to pair documents with editors who have relevant expertise.

    The editing manager reviews each file before assigning it to the most suitable editor on our team. We will always select the editor whose experience and qualifications are the best match for the subject of the paper.

    While we make every effort to ensure that your editor has experience in your discipline, we cannot always guarantee that the editor will be an expert in your sub-discipline. For example, if you submit a paper on molecular biology, we may select an editor with a background in the wider discipline of biology but not necessarily in the specific sub-discipline of molecular biology.

  • How will my document be returned to me?

    We’ll email you a secure download link to your edited document.

    You’ll be able to download both ‘tracked’ and ‘clean’ versions of your file. The ‘tracked’ version shows the editor’s changes and comments, while the ‘clean’ version has all of our changes accepted and all tracking and comments removed.

    We won’t send any physical or printed copies.

  • Do you offer writing, paraphrasing or translation services?

    No, we don’t offer writing, paraphrasing or translation as part of our service. We focus on providing a premium-quality editing and proofreading service.

  • What if I have follow-up questions?

    We are happy to answer any questions you may have after you’ve received your edited document. Simply contact us and we’ll provide a prompt and full response to your questions.

  • Can I request the same editor as before?

    Absolutely! Simply note this on the order form and we will assign your new order to your preferred editor, subject to their availability.

  • What if I’m unhappy with the results?

    If you’re unhappy with the editor’s work, please contact us and we’ll find a suitable resolution. This may take the form of a free re-review by a different editor, or a partial or full refund, depending on the circumstances.

  • What file formats do you accept?

    We prefer the following file types, as they allow us to use Microsoft Word’s Track Changes feature, which highlights the amendments made by the editor.

    Microsoft Word (DOC, DOCX, RTF)
    Open Office (ODT)
    Apple Pages (PAGES)

    We also accept:

    PDF (see below)
    LaTeX (see below)

  • Can you verify or complete references?

    If you list your requirements in the order notes, we will check that your references are consistent with your preferred style guide. However, we don’t supply reference content or cross-check references with original sources.

    Note that we don’t convert author-date styles to numeric styles, or vice versa; for assistance with this, please contact us for a bespoke quotation at [email protected].

  • Will my files be kept secure and confidential?

    Any files submitted to us will be kept in the strictest confidence.

    Only members of the Cambridge Proofreading team will have access to your files. We do not share client files externally under any circumstances.

    All client files are automatically deleted from our system 15 days after we complete the order. If you’d like us to delete them sooner, please email us—we are more than happy to oblige.

  • Will you re-review further changes that I make?

    We’ll gladly review minor changes to your completed order. Provided the changes aren’t extensive (less than 10% of the original order’s word count), there will be no extra charge. If you’d like us to review substantial changes (more than 10% of the original order’s word count), an additional charge will apply.

They also have years of editing experience and are members of leading industry bodies, such as the Council of Science Editors (CSE) and the Chartered Institute of Editing and Proofreading (CIEP). Our stringent recruitment process ensures that we work with only the best editors: less than 1% of the editors who apply to us are accepted into our network.

  • Do you accept LaTeX files?

    We can edit LaTeX files in either Microsoft Word or Overleaf. Click here to read about our Overleaf editing services.

    If you prefer Overleaf, please add [email protected] to your file as a collaborator. We’ll edit your file directly in Overleaf, highlighting our changes with  Overleaf’s Review feature.
