“Martin is a fantastic book doctor. I’ve worked with him on two different manuscripts and his feedback was always spot-on, insightful and sensitively given. When I signed on with him I was looking for editorial advice, he gave me that in spades along with a masterclass in creative writing.”

Victoria Selman, Amazon Number One best-selling author of Blood for Blood.

With over 15 years at a senior editorial level in major publishing houses (Penguin and HarperCollins), I am an extremely experienced editor. In that time, I read, appraised and edited hundreds of proposals and completed manuscripts. The subjects I commissioned and edited ranged from biology to ancient history (through language usage and psychology). Now I offer an editorial consultancy service for your fiction and non-fiction manuscript or outline. The consultancy can range from advice on your proposal to full structural review with detailed constructive editorial notes to improve your manuscript. I am honest in my appraisal, will give you realistic feedback and can give advice on the best next steps to take. I now also offer a complete book packaging service – using my expert contacts in the publishing world, I can manage the production process from unedited manuscript to delivery of bound copies. Please do get in touch either through the Contact page on this website or you can email me at martin.toseland@gmail.com.


“I’ve worked with Martin, on a variety of projects, since the mid-90s. He’s been my first port-of-call whenever I need editorial advice on a new project, and I’ve no hesitation in recommending anyone else in need of an editor to do the same.”

Professor David Crystal, best-selling author of over 100 books including Spell It Out

“Martin has proven himself to be excellent in my experience at taking the loose threads of a proposal or idea and shaping it into something intelligent, commercial and exciting. He understands what is needed from the publisher’s perspective, being able to position a book successfully, as well as having the sensitivity and tenacity to help focus authors, whether that means re-working text or coming up with a sound structural framework for them to work to.”

Denise Bates, Group Publishing Director, Conran Octopus

“Martin is a wonderful editor and I always consult him on my drafts.  With both fiction and non-fiction his judgement is clear-sighted and precise. He has a fine sense of structure and can point to exactly where a work has gone lopsided or pull out the elements that are working well and put them in the right place.”

Julia Rochester, author of The House at the Edge of the World Longlisted for the Baileys Women’s Prize for Fiction 2016 and shortlisted for the Desmond Eliot Prize 2016

“Martin has fantastic insight that improves any project at any stage.”

Myles Archibald, Publishing Director, William Collins/HarperCollins

“Martin was a terrific editor for my manuscript. I only wished I’d brought him in earlier in the writing process! He carefully removed material which neither fit in nor added to the core argument. He was able to draw out the major points to my argument without losing my voice. And he was really easy to work with, being both accessible but also sensitive in our discussions.”

Dr Saqib Qureshi, author of Reconstructing Strategy: Dancing with the God of Objectivity

“When it comes to a critical review of your manuscript, Martin has an uncanny knack of getting straight to the nub of the matter – the awkward passage, a rough transition, the place where confusion enters, the time to re-invigorate the story, a lost opportunity, an unfinished thought, a clash of tone, the underlying simplicity that needs to replace current complexity… I have turned to Martin twice for editing advice and will not hesitate to do so again. If you want readers to be captivated by your writing then he will save you much time and grief, and at the same time give you a masterclass in story-telling.”

Martyn Murray, author of The Storm Leopard and Beyond the Hebrides

“Martin came up with seminal ideas for improving my first novel, including a change of title. Undoubtedly the polish he added when editing proved to be the key factor in finding a publisher. I didn’t think twice before sending him my second as soon as it was ready.”

Barry Morgan, author of Gift Horse

“Here’s what you get: someone who knows what he’s talking about (rare), with good common sense (unusual), and who is genuinely enthusiastic about your project (hilariously ideal).”

Belle Robertson, author of Tired of Thinking About Drinking: Try my 100-day Sober Challenge

“Martin and I worked together on my book in 2014. He took the draft manuscript and managed the whole process from editing to delivery of finished copies seamlessly – finding excellent people to perform each stage of the production process. All through the process Martin exhibited high levels of integrity, project management and dedication to the process. It was a real pleasure to work with him and I’d have no hesitation in recommending him to anyone who wants to get their manuscript turned into a book of the highest quality.”

Saeed al Muntafiq, author of A Warrior’s Journey


Although I was an experienced technical author who thought that writing a biography would be a simple extension of those skills, I was advised to still use a good editor. Not only am I glad that I took that advice, but also that I used Martin Toseland.  His extensive experience of the commercial publishing industry shone through immediately, and his many observations on what I thought was a finished manuscript were astute and absolutely right.
