Book Editing Services

Editing That Makes Every Page Earn Its Place.

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.

The Service

Good Editing Is Invisible. Bad Editing Is All You Notice.

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.

  • Developmental and structural editing
  • Line editing for rhythm and clarity
  • Copy editing to publishing standard
  • Final proofread on typeset pages
  • Editorial letter with every pass
  • Style sheet built for your book

Levels of Editing

Six Ways We Work On a Manuscript.

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.

01

Manuscript Assessment

Start here if unsure

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.

  • Full read plus written report
  • Sample edit of 1,000 words
  • Clear recommendation and quote
02

Developmental Editing

The foundations

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.

  • Chapter-by-chapter structural notes
  • Pacing and tension mapping
  • Arc, theme and consistency review
03

Line Editing

Sentence-level craft

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.

  • Rhythm, flow and sentence variety
  • Redundancy and filter-word removal
  • Tone and register consistency
04

Copy Editing

Correctness and consistency

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.

  • Full grammar and punctuation pass
  • Bespoke style sheet for your title
  • Continuity and fact-flagging
05

Proofreading

The final gate

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.

  • Read on final typeset proofs
  • Layout, running heads and captions
  • Front and back matter checked
06

Blurb & Back Cover Copy

The 150 words that sell

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.

  • Back cover blurb and strapline
  • Retailer-formatted description
  • Author biography polished

What You Receive

Not Just a Cleaner File — a Better Writer.

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 Manuscript
  • Fully tracked Word manuscript
  • Clean accepted-changes version
  • Editorial letter, three to eight pages
  • Bespoke style sheet for your book
  • Margin comments explaining each call
  • A follow-up call with your editor

How It Works

From First Read to Final Proof.

Four stages, agreed in writing before anything starts, with a named editor you can email directly throughout.

Free Assessment

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.

Meet Your Editor

A genre-matched editor is assigned. You agree scope, English variant, style preferences, any sacred cows, and a delivery date you can plan around.

Editing Rounds

The manuscript moves through the agreed levels and returns with tracked changes, margin comments and your editorial letter. You review at your own pace.

Final Polish

Your responses are integrated, questions resolved on a call, and a closing proofread locks the manuscript ready for typesetting and publication.

Our Editors

Vetted Against the Books They Have Actually Edited.

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.

  • Trade or academic publishing background
  • Live sample edit before hiring
  • New Hart’s Rules and Oxford style
  • Chicago style for US-market titles
  • Matched to your specific genre
  • Swap editors after the sample, free

The Kingswell Difference

Why UK Authors Choose Kingswell.

We are a British publishing services company, not a rights-taking publisher. That single distinction shapes everything below.

You Keep Every Right and Every Royalty

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.

One Named Project Manager

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.

Genre-Matched Specialists

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.

Honest Scoping, Fixed Quotes

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.

Confidential by Default

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.

British Publishing Standards

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.

Common Questions

Book Editing FAQs.

Straight answers about levels, timelines, cost and what editing will and will not do to your voice.

Which level of editing does my book need?
That is exactly what the free assessment answers. Broadly: if you are unsure whether the story works, you need developmental editing. If the story works but the prose feels flat, you need line editing. If it reads well but you are worried about errors, you need copy editing and a proofread. Many manuscripts that have already been through beta readers and a few drafts need only the last two — and we will tell you that rather than sell you all four.
Will editing change my writing style?
No. Our editors are trained to strengthen your voice, not replace it with theirs. Every change arrives as a tracked suggestion you can reject with one click, stylistic preferences are agreed before work starts, and if you want to keep a deliberate sentence fragment or an unconventional rhythm, you say so and it stays. If an edit ever comes back reading like someone else wrote it, that is a failure on our part and we will redo it.
How much does book editing cost?
It depends on length and which levels the manuscript needs, so we quote per project rather than publishing a rate that would be wrong for most books. Editing is also bundled into our publishing plans — the Classic plan at £999 includes an editorial evaluation, and the Signature plan at £2,199 includes a full edit alongside design, distribution and a video trailer. The assessment and quote are free and carry no obligation.
How long does professional editing take?
A typical 70,000 to 90,000 word manuscript takes two to four weeks per pass. Where several levels are combined they run back-to-back with your review time in between, so a full developmental-plus-line-plus-copy journey usually spans eight to twelve weeks. You get exact dates in writing before we begin, and if you have a hard deadline, say so early and we will tell you honestly whether it is achievable.
Do you edit in UK or US English?
Both, and we apply whichever you choose consistently across spelling, punctuation, date formats and quotation style. UK English is our default. If you are publishing on both sides of the Atlantic we will discuss whether a single consistent variant or two separate editions serves you better — for most independent authors, one consistent variant is the right call.
What file formats do you work with?
Microsoft Word with tracked changes is the standard and what we recommend, and we also work in Google Docs. If your manuscript currently lives in Scrivener, Pages, PDF or even typed pages, send it as it is — converting it cleanly into an editable file is part of the service, not an extra.
Can you edit a book not originally written in English?
Yes, and we do it regularly. Translated and second-language manuscripts get an editor experienced in smoothing phrasing into natural, idiomatic English without flattening the cultural texture that makes the book distinctive. Where a phrase does not carry across, we flag it and ask you rather than guessing.
Do you use AI to edit manuscripts?
Your manuscript is edited by a named human editor. Software has its place for mechanical consistency checks — catching a character whose eyes change colour, or a hyphenation pattern that drifts — but every judgement about your prose, structure and voice is made by a person who has read the whole book. Your manuscript is never used to train anything.
