Expert editing & proofreading services tailored
to meet your audience needs

  • Do you offer sample edits?
    Yes, in most cases I offer free sample edits of up to 1,000 words , with no obligation. A sample edit is a really helpful way for both of us to decide whether we are a good fit for each other. It will give you a feel for my editing style, and it also helps me to better understand what you’re looking for and more accurately estimate how long a project will take.
  • What are your terms and conditions?
    If you would like to find out more, please feel free to contact me using the contact form above. I would be very happy to discuss my terms and conditions as part of any project discussion.
  • Do your services maintain the original voice and intention of the author?
    Absolutely. My aim is not to alter your voice but to enhance it. I focus on improving clarity, coherence and readability while preserving your unique perspective and intention.
  • What types of documents do you proofread and edit?
    I am experienced in editing and proofreading a wide range of documents including academic articles, research papers, policy briefs, reports, presentations and more.
  • How long does the editing and proofreading process usually take?
    Turnaround time can vary depending on the length and complexity of the document as well as the level of editing required. I always strive to work within client deadlines and will provide a more specific timeframe once we have both agreed on the scope of your project.
  • How do you ensure the confidentiality of a client's work?
    I take confidentiality very seriously. I partner with my clients to agree and adhere to strict non-disclosure and confidentiality requirements for each project, giving you confidence and assurance that your work is protected.
  • What qualifications do you have?
    I am an Advanced Professional Member of the Chartered Institute of Editing and Proofreading (CIEP). I am also a Full Member of the Association of Freelance Editors, Proofreaders & Indexers of Ireland (AFEPI Ireland). Both of these recognised qualifications, combined with over 14 years of industry experience, provide confidence and reassurance to my clients.
  • Do I really need an editor and proofreader?
    Modern technology allows us to do a lot for ourselves. At the same time, even the most accomplished writers benefit from a second pair of eyes. As a professional, experienced editor and proofreader, I can spot errors or inconsistencies that you may have overlooked due to familiarity with the content. With over 14 years of industry experience, I can also provide valuable insights on structure, coherence and clarity that can enhance your work. The value of having a professional, experienced editor and proofreader extends beyond the cost. Errors or lack of clarity in your documents can undermine your credibility and the impact of your work. By partnering together on your project, I help to ensure your ideas are communicated effectively, enhancing your reputation and the influence of your writing.
