A developmental edit costs £1,500–£4,800 for a full-length book; Reedsy's published average is around $2,880 for 80,000 words. Editors quote on length and condition, which is why two quotes for 'a novel' can differ by two thousand pounds.
What it costs
What developmental editing costs, and whether you need it
What good looks like
- A written report of several thousand words, not a marked-up file
- A clear statement of what the book is currently about, which you can compare with what you intended
- Specific structural recommendations, in priority order
- At least one thing they think you should cut that you will not want to

What you are actually buying
A developmental editor reads the whole manuscript and tells you what is wrong with the book — the structure, the order, what is missing, what should go. They do not touch your sentences. It is the most valuable edit and the one most often skipped, because it is the one that asks you to rewrite.
Why it costs that
A developmental edit is priced on reading the whole book carefully, thinking about it, and writing ten to thirty pages of diagnosis. Editors quote on length and on condition — a rough 120,000-word manuscript takes far longer than a clean 70,000-word one, which is why two quotes for 'a novel' can differ by £2,000. Reedsy's published average for an 80,000-word developmental edit is around $2,880, and UK freelancers cluster between £1,500 and £4,800.
How to spend less
Buy the assessment first. £400–£900 for a report on whether the book works is the highest-value editorial purchase there is, and it frequently means you never need the full edit. Then do the revision it names before commissioning anything else, because editors price on condition — a better draft is a cheaper quote and a more useful report.

Questions to ask them
- What will the report cover, and roughly how long is it?
- Do I get a conversation afterwards?
- Have you worked on this genre, and can I see an anonymised sample report?
- What happens if I disagree with the central recommendation?
Red flags
- A quote that does not depend on word count
- Promises about agents or publication
- No sample report available in any form
- Line edits included — that means they are not doing developmental work
Honestly
If you are only going to pay for one edit, pay for this one. A beautifully copy-edited book with a structural problem is still a book with a structural problem.
What Your Book Pro does here
Your Book Pro is a British book-writing platform. You bring a book — an idea, a folder of notes, half a draft, or a finished manuscript written somewhere else — and it gives you the editorial process a publisher would run: a plan, structured feedback, a simulated beta read, a line edit, a proofread, a cover, a blurb and a print-ready file. You can type it, upload it or speak it. The tools sit in one place and work on the same manuscript, so the feedback compounds instead of arriving as twelve disconnected opinions.
These prices are here to be used, not to sell you something — brief a freelancer with them, sanity-check a quote, or work out what you actually need. Where Your Book Pro changes the arithmetic, the page says so; where it does not, it says that too.
If you are only going to pay for one edit, pay for this one. A beautifully copy-edited book with a structural problem is still a book with a structural problem.

Review my openingQuestions people ask
- What's the difference between a developmental edit and an assessment?
- An assessment diagnoses; a developmental edit diagnoses and then works through the fix with you in detail, chapter by chapter.
- How long does a developmental edit take?
- Four to eight weeks, and good editors are booked two to three months ahead. Ask about the queue before the price.
- Is it worth it for a self-published book?
- Often the assessment is, and the full edit only if the assessment says the book needs developing rather than fixing.
- Can I get a partial developmental edit?
- On an outline and three chapters, yes — that is a plan critique at £150–£400. On half a book, no: structure cannot be judged without an ending.
