What does a book editor do?
Four different jobs share the word editor: developmental, line, copy and proof. They happen in that order, cost different amounts, and cannot substitute for each other. Hiring the wrong one — usually a copy-editor when the book needs a structural read — is the most expensive mistake in self-publishing, because you pay twice.
Quick facts
- What it is
- A guide to the four jobs that share the word editor: developmental, line, copy and proof.
- Best for
- Authors working out which editor to hire, and in what order, so they do not pay for the same work twice.
- What it does
- Explains what each of the four editors does, the order the passes run in, and roughly what each costs in the UK.
- What it does not do
- It does not edit your book, and it cannot tell you which pass your own manuscript needs next.

Four editors, four jobs
Find the row that matches the problem you actually have. If two rows sound right, start with the higher one — the lower ones do not survive the changes the higher ones ask for.
| Role | The question they answer | Typical UK cost | Comes after |
|---|---|---|---|
| Developmental / structural editor | Does the book work? Is it about what it thinks it is about? | £1,500–£4,800 | A complete draft and, ideally, beta readers |
| Line editor | Does each paragraph do its job? Is the prose alive? | £800–£2,000 | Structure is settled and won't change |
| Copy-editor | Is it correct, consistent and in one house style? | £800–£1,600 | Line editing, or instead of it on a clean draft |
| Proofreader | Are there errors in the file that is about to print? | £400–£800 | Typesetting |
| Editorial consultant / 'ask an editor' | A specific question: is this opening working? Is this structure sound? | £60–£150 an hour | Any time you're stuck |
A separate free preview: A free outside view of your own pages
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. Send up to 5,000 words. You get back what the draft appears to be doing to somebody who wasn't there when you wrote it, the strongest thing in it named, the exact place a reader starts to drift, and three revision priorities in order.
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. An AI-assisted read of your own pages. Not a human edit, not a line edit, and not a scored report.
Why the order is not negotiable
Each pass assumes the one above it is finished. A line editor polishing chapter nine is wasted money if the developmental read is going to cut chapter nine. A copy-edit is invalidated by any structural revision, and a proofread is invalidated by a copy-edit.
This is the actual mechanism by which self-published authors overspend: not by paying too much per pass, but by paying for the same pass twice because they started at the wrong end.
What each one actually sends you
Developmental: a report, ten to thirty pages, sometimes with margin notes. Occasionally a call. It will not fix anything — it tells you what to fix.
Line edit: the manuscript with tracked changes, sentence by sentence, plus a covering note about recurring habits.
Copy-edit: tracked changes, queries in the margins, and a style sheet — the document recording every decision made about your book's spellings, names and conventions. The style sheet is arguably the most valuable deliverable and the one authors most often ignore.
Proofread: a marked file or PDF annotations. No queries about meaning; it is too late for those.
What editors don't do
They do not rewrite your book. A good line editor changes what is on the page as little as possible while making it work; if the returned manuscript sounds like someone else, that is a failure, not thoroughness.
They do not guarantee a sale, an agent or a review. Any editor implying otherwise is selling something else.
And they do not decide. Every tracked change is a proposal. The author accepts or rejects, and an author who accepts all changes without reading them has bought a different book.
The cheapest useful editorial product
Most authors do not know it exists: a manuscript assessment, sometimes called an editorial report. £400–£900 for an experienced reader to read the whole book and tell you, in ten pages, whether it works and what the two or three real problems are.
No markup, no line-by-line, no six-week wait for a full developmental edit. For authors deciding whether to invest thousands, it is the right first purchase, and it frequently saves the thousands.
The second cheapest is an hour of an editor's time on a specific question. £60–£150 buys a straight answer about whether your opening chapter is doing its job — often more useful than a full report you are not yet ready to act on.

Start with an idea, notes, half a draft, a podcast, or a finished manuscript, and use our purpose-built AI tools for planning, feedback, editing, proofreading, cover designs, and to create print-ready files. Writing is totally free: you can type, upload or speak your book as much as you like, and use only the editing tools you need with Plus, or go unlimited with Pro.
Produce world-class drafts at the fraction of the cost of hiring a human editorial team.
Every account starts with 1,000 welcome credits, and a plain export of your own words is free.
Each guide says plainly when a person does the job better than AI. Guides on legal topics are general information, not legal advice.
Two things map onto this page. Ask the Editor is the pill that stays with you in the top corner of every screen — it answers a specific editorial question about your actual manuscript, at the moment you have it, rather than in six weeks' time. Is this opening doing its job? Have I set this up properly? Is this chapter earning its place?
The Editing Suite is the one place where the passes happen in the right order on the same manuscript: structural feedback first, then the line and copy work, then the proofread. Because it is all one manuscript, each pass knows what the last one changed — which is precisely what you lose when you hire four freelancers separately.
The honest limit: a one-off conversation with an editor who has actually sold books in your genre buys market judgement that no rubric holds. If your book is going to agents, that conversation is worth having. Arrive at it with a good draft.

- Do I need all four editors?
- No. Most self-published books need a structural read and a proofread, with a copy-edit if the prose is inconsistent. A full four-stage sequence is a trade-publishing standard, and costs £2,500–£6,000.
- What's the difference between line editing and copy-editing?
- A line editor changes how a sentence sounds; a copy-editor changes whether it is correct and consistent. In practice many freelancers offer a combined pass, which is fine on a clean manuscript and a false economy on a rough one.
- How do I find a good editor in the UK?
- The CIEP directory is the reliable starting point — Advanced Professional Members have been assessed. Then Reedsy, then referrals from authors in your genre, which are the best of all.
- Can one person do all the passes?
- They can, but fresh eyes catch more. Most authors use one editor for the structural and line work and a different person to proofread, precisely because the first editor has stopped seeing the text.
- How do I know which edit I need?
- Describe the problem, not the service. 'Readers get bored in the middle' is developmental. 'It's correct but flat' is line. 'I keep finding inconsistencies' is copy. 'It's finished and typeset' is proof.
