Book Editing Services
From the shape of the whole book down to the final comma, our genre-specialist editors work through your manuscript in deliberate layers — strengthening structure, sharpening prose and correcting error, while fiercely protecting the voice that made you write it in the first place.
Edited to trade standard
The Service
Readers rarely praise a well-edited book. They just keep turning pages. What they do notice — and mention in reviews — is a saggy middle, a character who changes name in chapter nine, or a typo on page one.
Your manuscript moves through a structured pipeline rather than a single vague pass. Developmental editing deals with the foundations: does the structure hold, does the pace carry, does the argument land, does the protagonist actually change? Line editing then works at sentence level on rhythm, clarity, repetition and tone. Copy editing enforces grammar, consistency and house style. A final proofread catches whatever survived the previous three.
Crucially, we only recommend the layers your book needs. A manuscript that has already been through a good developmental edit does not need another one, and we will say so in writing rather than quietly adding it to the invoice.
Levels of Editing
Take one, take several, or let a free assessment tell you which your book genuinely needs. Levels are applied in order, because there is no sense polishing sentences in a chapter that is about to be cut.
A senior editor reads the manuscript and writes you an honest report: what is working, what is not, and which editing levels would actually move the needle. No obligation to buy anything afterwards.
The big structural work. Plot logic, pacing, chapter order, point of view, character arcs, and for non-fiction, whether the argument is built in the right sequence for a reader who does not already agree with you.
Where prose becomes readable. We cut the throat-clearing, vary the rhythm, kill the repetition you stopped seeing on the twelfth read, and tighten dialogue until it sounds like people rather than exposition.
Grammar, punctuation, spelling, tense, hyphenation, capitalisation and continuity, applied against a style sheet built specifically for your book so the same decisions hold from page one to the last.
A last meticulous read of the typeset pages, not the Word file — because that is where bad line breaks, widowed headings, dropped italics and stray double spaces actually live. Nothing goes to print without it.
The hardest paragraph in publishing, written by people who write them weekly. A hooking back-cover blurb plus an Amazon description formatted for the retailer, tuned to your category and your reader.
What You Receive
Every edit comes back as tracked changes with margin comments explaining the reasoning, plus an editorial letter that steps back and talks about the book as a whole. You accept or reject every single change. Authors regularly tell us the letter taught them more about their own writing than any course did.
Send Your ManuscriptHow It Works
Four stages, agreed in writing before anything starts, with a named editor you can email directly throughout.
Send the manuscript. We read a substantial sample, edit 1,000 words of it properly, and come back with an honest view of what it needs — and what it does not.
A genre-matched editor is assigned. You agree scope, English variant, style preferences, any sacred cows, and a delivery date you can plan around.
The manuscript moves through the agreed levels and returns with tracked changes, margin comments and your editorial letter. You review at your own pace.
Your responses are integrated, questions resolved on a call, and a closing proofread locks the manuscript ready for typesetting and publication.
Vetted, publishing-trained
Our Editors
Anyone can call themselves an editor. Our test is simple: show us the published books you worked on, then edit a real sample under time pressure.
Every Kingswell editor comes from a trade or academic publishing background and is assessed on a live sample edit before they take a single client manuscript. We check technical accuracy against the standards used across British publishing — New Hart’s Rules and the Oxford style conventions for UK titles, Chicago for authors targeting the US market — and we check judgement, which matters more.
Then we match by genre. The editor who is brilliant on a police procedural is not automatically the right hand on a grief memoir. You are told who your editor is, what they have worked on, and you can ask for a different one after the sample edit if the fit feels wrong.
The Kingswell Difference
We are a British publishing services company, not a rights-taking publisher. That single distinction shapes everything below.
Copyright stays registered in your name and retailer accounts are opened in your name. We take no commission and no revenue share — one hundred per cent of what your book earns is paid straight to you.
No ticket queues and no being passed between departments. A single publishing consultant coordinates every specialist on your book and stays your point of contact from first call to launch day.
A thriller needs different instincts to a memoir, and a business book different rigour to a children’s picture book. Your project is staffed by people with a track record in your specific genre.
We tell you what your book genuinely needs and what it does not. Every quote is agreed in writing before work begins, so there are no mid-project surprises and no upselling.
Your manuscript is only ever seen by the specialists working on it. NDAs come as standard and your identity, your story and your ideas are never shared or reused.
Based in Fitzrovia, London. We work in UK English by default, price in pounds sterling, and typeset to the trade standards British readers and booksellers expect.
