Generous words from people Ive worked with


We had a great experience working with Cath on our wildlife farming report. She was flexible, efficient and reliable, and adhered to both the brief and timeline we provided. She was also quick to respond to all communication. Professional and high-quality service all round.

JENNAH GREEN, Wildlife Research Manager, World Animal Protection

Landscape Change in the Scottish Highlands-James Fenton

It is surprising how many things you miss when you think you have the perfect manuscript! Hence it is always useful to have someone go through it with an impartial eye, commenting on comprehension, inconsistencies, grammar and punctuation. Cath did an excellent job for me and her suggestions have significantly improved my book.

Copywriting for WWT by Cath Harris, Words for Keeps

We greatly value the detailed and thorough copyediting and proofreading Cath has done on several strategic documents. Her fresh eyes and professional approach have tightened up and refined language, grammar, punctuation and flow, enabling us to publish the documents with confidence. We would highly recommend Cath’s editing services.

EMMA FAURE, Marketing Executive, Wildfowl & Wetlands Trust


One of the things I have learned in a lifetime of writing hundreds of scientific papers, popular articles and several academic books is that even an experienced author makes mistakes, and that a good copyeditor is worth their weight in gold. Cath did a great job on my manuscript, picking up errors I should have spotted and meticulously going through the hundreds of notes and references linked to the text. I was very impressed. And she did it quickly and courteously, as well as thoroughly.

PROFESSOR SIR JOHN LAWTON CBE FRS, author, Inn Search of Birds


Cath is a wonderful copyeditor. She helped me refine my PhD thesis in Media and Communications. I would especially recommend her to international students who are submitting their dissertations. Thank you again for your help with my work.

JULIANA HOLANDA, doctoral candidate


This is the first time I have used a professional proofreader and I must say it has been a very pleasurable and worthwhile experience. I admire your great attention to detail and I love the style sheet – so helpful to be alerted to some of my idiosyncrasies. I’m sure I will be in touch with further work in the future.

DEBORAH SOUTHWELL, master’s candidate

Funding bid writing for Flight of the Osprey by Cath Harris, Words for Keeps

Cath has a talent for turning complex science into copy we can all understand. She does this quickly and efficiently, and rarely are subsequent changes needed. I’d have no hesitation in recommending Cath for science-related writing or editing work.

SACHA DENCH, CEO, Flight of the Osprey; UN Ambassador for Migratory Species

Cath has a terrific talent for writing with the voice of an organisation and individual, turning complex and dense research into accessible news on an amazing breadth of areas in no time at all. She has calm perspicacity, persistence and objectivity, which I suspect she could maintain even in a tornado. She can spot 100 per cent of mistakes, which must be a gift and a curse.

SALLY AMBERTON, Smith School of Enterprise and the Environment, University of Oxford


Cath is an outstanding copyeditor. She turned my rough draft into a clean, readable text. I would definitely recommend her to anyone who is looking for an editor for an academic book, short article or long-form essay.

TARILA MARCLINT EBIEDE, University of Leuven

Funding bid writing for Flight of the Osprey by Cath Harris, Words for Keeps

Cath’s clear and accessible writing style helped us incorporate the science of osprey migration into our bid documents, and her editing skill meant we stayed within the very tight wordcount. One section was superb. We could use it as is.

DAVID WARD, bid writer, Flight of the Osprey


I was very fortunate to have Cath Harris assigned to edit my book. Cath sensitively turned my manuscript into a much-enhanced and readable script. She was very efficient and approachable and always aware of the author’s message. A pleasure to work with.

BILL RIBBANS, author, Knife in the Fast Lane


Cath is perhaps the most painstaking and brilliant copyeditor I have worked with.

DR CHUKS OKEREKE, Smith School of Enterprise and the Environment, University of Oxford


Cath Harris is the ultimate professional. She edited my book, Visionary, and her suggestions, especially concerning the sequencing of various passages in the narrative, have improved the final work immensely. Her suggested cuts, too, were really helpful, and her eye for detail was invaluable. I can’t thank her enough.

PHILLIP VINE, author, Visionary


Cath has a seldom-equalled ability to turn complex and scientific areas of work into accessible and newsworthy stories that generate acres of media coverage.  She understands the media generally, and journalists’ requirements specifically, and uses this knowledge to constantly root out new press opportunities for organisations. She can be trusted to deliver exactly what she says she will.



Cath wrote a press release for my new Hello Trees books and I have sold more books as a direct result of it than through any other marketing initiative. She also wrote a charming article about my books in Herts Countryside magazine. I am most grateful to Cath. She has talent for knowing how to put into words exactly what is needed for the target audience.

KATE BRETHERTON, author, Hello Trees


Having gone through an extensive two-stage edit for an ESL client, I felt the book needed a fresh set of eyes for a proofread. Cath was thorough and her work detailed and painstaking. She picked up on very specific points and gave new insight to some particularly sticky sentences. Highly recommended!

LESLEY JONES, copyeditor

Until We Meet Again in Jannah

Cath was extremely helpful and was able to polish my book, picking up things I had missed time and time again. I found Cath to be extremely reliable to work with, completing the work in the time I had requested. I have already recommended her services to others. Thank you, Cath!

LAKI KHAN, author, Until We Meet Again in Jannah

Until We Meet Again in Jannah

Absolutely super job by Cath. Constant communication meant we were able to get the book to the printers on a very tight schedule. Very high-quality work. I would definitely recommend Cath for any proofreading work.

SARAH JUGGINS, Co-author, Under an Orange Sky

Cath wrote a super article in The Countryman about the work of the Trust and has very good conservation knowledge. Her writing is both intelligent and insightful.

CHRISSIE KELLY, Pensthorpe Conservation Trust

Until We Meet Again in Jannah

Cath is an excellent writer who works quickly to high quality standards. She not only delivers her work ahead of schedule and in excellent condition but is also open to further editing requests.

DR BETTINA WITTNEBEN, Smith School of Enterprise and the Environment, University of Oxford

Until We Meet Again in Jannah

Cath’s work illustrates her excellent research skills, and her delivery and attention to detail are outstanding. She has translated a huge variety of briefs into engaging articles and shown initiative and creativity in coming up with new and exciting topics.

MAGDALENA SCHOERNER, Social Media and Content Editor, Evans Cycles (UK)

Until We Meet Again in Jannah

I was initially reluctant to have an article written about my career as a professional stunt performer, but with her professionalism, integrity and professional writing style, Cath created an honest, accurate and articulate account of my work of which I am truly proud.

BELINDA MCGINLEY, Professional Stunt Performer

Report proofreading for Bedfordshire Police Commissioner. Cath Harris. Words for Keeps

Working to a very tight timescale Cath undertook a high level review item for the Office of the Police and Crime Commissioner for Bedfordshire which I, as Chief of Staff, was incredibly pleased with. Professional, courteous and incredibly skilled at her craft.

CLARE KELLY, Chief of Staff, Office of the Police and Crime Commissioner for Bedfordshire

Report proofreading for Bedfordshire Police Commissioner. Cath Harris. Words for Keeps

Much impressed. I have been making a hash of things and your competence offers a shining example.

PETER FRASER, OperaScotland

Report proofreading for Bedfordshire Police Commissioner. Cath Harris. Words for Keeps

Cath’s writing for ATW websites is imaginative, original and very professional. She writes to suit the speedy way we read online and goes the extra mile by proofreading text provided by sponsors. I’d definitely recommend her to others needing content for their websites.

JAMES SHIPLEY, Director, Active Training World, Herts

Cath is a prompt, professional and effective proofreader with a reliable eye for both surface and underlying problems. She engages with the work and explains her recommendations.  I would recommend her to anyone who cares about the impact and import of their words.

PAUL MAY, writer, Green Park Publishing

We have been absolutely delighted with the high standard of work Cath has carried out for Pitch Publishing — both in terms of editing and proofreading. She has a good eye for detail and her jobs are always returned on time (or earlier) and within budget

PAUL CAMILLIN, Director, Pitch Publishing

I needed the expertise of a professional proofreader to polish my screenplay and found Cath to be vastly experienced, professional and very approachable. I can’t speak highly enough of this lady because I know what hard work I could be at times, but she always delivered when she said she would.

ROB SELBY, independent screenplay writer


Cath provided a swift, professional and friendly service for our Garden City Runners’ website. She has great attention to detail and I wouldn’t hesitate to use her services again. It was so helpful to have a pro cast their eye over what we had cobbled together — thank you very much indeed.
