  • 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.

  • Can you verify or complete references?

    We can check that your references are formatted in line with your preferred style guide; just list your requirements in the order notes. Note that we don’t supply reference content or cross-check references with original sources.

  • 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.

  • Will my files be kept secure and confidential?

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

    Only the editing manager and your assigned editor will access your files. We will not share them externally under any circumstances.

    All client files are automatically deleted from our system 21 days after we complete the order. If you’d like us to delete them sooner, simply email us and we’ll be happy to oblige.

    We will gladly sign non-disclosure agreements (NDAs) if required.

  • 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.

     

  • Will you sign a non-disclosure agreement (NDA)?

    We are happy to sign NDAs on request. Please contact us for more information.

  • 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. 

     

  • Do you have a money-back guarantee?

    If you’re not satisfied with the service you’ve received and can cite fair justifications, we’ll provide a re-edit or issue a partial or full refund. Please contact us if you have any questions.

  • 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.

  • What will my proofread and edited document look like?

    All the editor’s changes are highlighted using the Track Changes feature in Microsoft Word, which allows you to see where improvements have been made. Your editor’s queries and comments will appear in the margin. Click here to see samples of our work.

  • 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 pair it with an editor with a background in the wider discipline of biology but not necessarily in the specific sub-discipline of molecular biology.

  • How will you improve my writing?

    For a detailed explanation and sample edits, see How we proofread and edit texts.

    We proofread for:

    Spelling, grammar, punctuation, and typographical errors

    We edit for:

    Academic style, tone and register
    Clarity and flow
    Incorrect sentence structure and awkward phrasing
    Wordiness and redundancy

    Our changes are highlighted using Microsoft Word’s Track Changes feature, allowing you to review and accept or reject each amendment. Click here to see samples of our work.

    We can review your document in line with any specific guidelines (e.g., APA, MLA, Chicago, Harvard, OSCOLA) or requirements that you may have.

    If you’re looking for a cheap, basic, rushed proofreading service, we suggest you look elsewhere, though we advise you to be vigilant of scam websites.

    If, however, you’re looking for a well-priced, premium-quality review and improvement of your writing, we can help.

  • How will my document be returned to me?

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

    You’ll receive a link to download the ‘tracked’ version of your file, which will show the editor’s changes and comments.

    You’ll also receive a link to the ‘clean’ version, in which all of our changes will have been accepted and all tracking and comments removed.

    We won’t send any physical or printed copies.

  • What are the key benefits of using your service?

    Please see ‘Why choose us?’ and ‘How we improve a text’ for an overview of the benefits of our service.

  • Do you offer writing, paraphrasing, or translation services?

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

  • Can you work to a specific style guide or format?

    Yes, we can edit documents to specific style or format guidelines.

    Our team of 300+ editing professionals includes format specialists across all of the main style guides, including AMA, APA, AP, Bluebook, Chicago, CSE, Harvard, IEEE, MLA, and OSCOLA. Be sure to specify any special requirements in your order notes when placing an order.

    If your university, target journal or publishing house has provided specific guidelines, we may be able to accommodate these. Please contact us if you have any questions.

  • 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.

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

    We’ll gladly review minor changes to your completed your order. Provided the changes aren’t extensive (below 10% of the original order’s word count), there will be no extra charge.

    If you’d like us to review substantial changes—for example, the entire document or sizeable sections thereof—an additional charge will apply.

  • 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.

  • Can I have the same editor if I submit in parts?

    Whenever possible, we assign work submitted in parts to the same editor to ensure consistency.

  • What if I am 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 are your editors’ experience and qualifications?

    All of our editors are native English speakers. They hold advanced degrees from leading universities and have significant professional experience in their fields. 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.

  • 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)

  • Do you accept LaTeX files?

    We can edit LaTeX files in either Microsoft Word or Overleaf.

    If you prefer Microsoft Word, please either export or copy and paste your text into a Microsoft Word document. We’ll edit the file, highlighting our amendments with Track Changes. After processing our changes, you can copy and paste the text back into your LaTeX editor.

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