Copy-editing and Proofreading



How are fees calculated?

The charge is an hourly rate, based on the level of editing required. The text may need a varying degree of work, from little or no intervention to extensive re-styling or even re-writing.

How many words can be edited per hour?

A well-written document requiring basic proofreading might be completed at a rate of around 3000 words per hour. On the other hand, in cases where the writer’s work requires significant amending, or where there are a number of citations, cross-references, notes, figures and similar to be checked, that number will be significantly reduced.

Basic proofreading

Checking for accuracy, completeness and consistency. Includes corrections to:

  • spelling
  • grammar
  • punctuation
  • formatting
  • references
  • typographical errors.

If during a proofread I discover areas of weakness which may benefit from a more thorough edit, I will advise you immediately so that you can decide whether a more detailed service may be more applicable.


As above, plus:

  • an edit of the structure of the text to ensure clarity of argument and thought processes
  • resolution of any anomalies, ambiguities or infelicities to ensure harmonisation of style and syntax
  • reconstruction of weak sentences or passages.


Each project will be priced individually, according to your requirements. For a free estimate, please contact me to arrange to send a sample document or chapter through (minimum 3 pages). The hourly rate will depend on the level of editing required, but will be in the region of £23 per hour for proofreading, £26 per hour for copy-editing and £30 per hour for significant re-writing.

I asked Lydia to copy-edit various publicity and strategy documents before publication. She delivered to a tight deadline and I found her approach efficient and flexible. Her work was thorough and accurate and included suggestions that added polish and elegance to the final text. I look forward to working with her again.
