How Much Does A Developmental Editor Cost In The Uk

Gary Smailes | 2 November 2025

What Drives the Cost of a Developmental Edit in the UK

Editors price time. More hours, higher fee. Here is what pushes the number up or pulls it down.

Word count and complexity

More words mean more pages to read, mark, and map. Complexity multiplies the work. Multiple POVs, dual timelines, heavy research, or a built world each add moving parts.

Two quick snapshots:

• 60k category romance, single POV, linear timeline. Clear external goal. Clean.
• 120k epic fantasy with four POVs, two calendars, a magic system, and a glossary.

Both deserve care. The second requires scene-by-scene tracking, timeline checks, and system logic tests. Expect more analysis hours.

Practical tip. Note word count by chapter. If one chapter swells to 5k while most sit at 2.5k, trim before you request quotes. Fewer words, fewer hours.

Draft readiness

Editors do surgery, not resuscitation. A rough draft with missing beats or a sagging middle needs diagnosis before solutions. A near-query-level draft needs refinement and sharpening. Different workloads.

Think in layers:

• Global issues. Premise, structure, stakes, argument order.
• Chapter flow. Setups and payoffs, scene goals, transitions.
• Line concerns. Repetition, pacing within paragraphs, voice drift.

If global issues still wobble, the edit runs deeper and longer. A cleaner draft shifts effort toward clarity and pacing, which is faster.

Mini test. Pick your midpoint scene. Write one sentence for the story problem before, one for the turn at midpoint, one for the new plan after. If you stall, structure needs attention. Build that before you book.

Genre and category

Some genres demand mapping. Others lean on framework logic.

• SFF. Rules, timelines, geography, and lore create extra checks. Map or it leaks.
• Memoir. Truth claims, ethics, and narrative distance need careful handling, plus a spine strong enough to hold life’s chaos.
• Narrative nonfiction. Throughline, sourcing, and reader promise must align across many sources.
• Category romance, prescriptive nonfiction, and some thrillers often ride known beats or frameworks, which speeds diagnosis.

This is not value judgment. It is workload.

Scope and deliverables

Scope sets the fee. An editorial letter only costs less than a full package with margin notes, a book map, calls, and a second pass.

Common elements and impact on time:

• Editorial letter. Big-picture diagnosis, priorities, and examples. Core deliverable.
• Margin comments. Targeted notes at scene level. Slower read, deeper guidance.
• Book map or reverse outline. Scene grid with purpose, stakes, and word count. Useful, time intensive.
• Debrief call. Align on plan, answer questions. Add prep and follow-up.
• Second pass. Pressure-test after revisions. Often priced as a fraction of the first pass, still real time.

Choose what you need for this stage, not everything you want, and you save both time and money.

Editor experience

Rates rise with experience. Genre specialists, ex-agents, and former in-house editors charge more. You pay for sharper diagnosis, market context, and scar tissue from books that reached readers.

A senior editor might spot the root problem in one pass, where a newer editor circles for longer. Faster insight, higher rate. Sometimes the totals meet in the middle. Fit matters too. A brilliant SFF editor is not the right pick for prescriptive health unless they live in that space.

Check samples, ask for a short diagnostic, and listen to how they frame solutions.

Schedule pressure

Rush jobs cost more. Editors protect quality and focus by limiting overlaps. A short deadline squeezes the calendar, so the premium covers late nights or reshuffled bookings.

Lead time in the UK often sits between two and twelve weeks. If a launch or submission date looms, book early. Flexible dates help you avoid rush fees and keep the edit thoughtful, not frantic.

Business factors

UK VAT sits at 20 percent for VAT-registered editors. If your editor charges VAT, you will see it on the invoice. No surprises if you ask early.

Hiring outside the UK brings fees. Currency conversion, PayPal or Stripe charges, and bank transfer costs nibble at the budget. Build a small buffer. If you run a limited company or sole tradership, keep records tidy for HMRC. Ask for a formal invoice with legal name, address, and VAT number where relevant.

Most editors ask for a deposit to reserve dates. Plan cash flow around that milestone.

Quick ways to lower cost before you request quotes

• Trim bloat. Cut five to ten percent. Start with throat-clearing intros, duplicate beats, and summary where a scene would work better.
• Clarify goals. One sentence on audience. One on reader promise. Three comps with a note on why you chose them.
• Lock scope. Decide between an editorial letter only or a full dev edit with comments and a call. Name a word-count cap.
• Stabilise the draft. Freeze new chapters for now. Park big ideas on a list for round two.

A two-step drill for this week:

1. Build a reverse outline. Chapter, purpose, word count, turning point. Thirty minutes for the first ten chapters. You will spot quick cuts.
2. Write your brief. Paste audience, promise, comps, non-negotiables, and three questions for the editor. One page max.

Send that pack with your sample. You will get tighter quotes, fewer caveats, and a schedule you can trust.

Typical UK Price Ranges (Ballpark)

Numbers matter here. You want a budget you trust before booking an editor. Use these ranges to get close, then ask for a firm quote.

Per‑word rates

For a full developmental edit, expect roughly £0.012 to £0.04 per word. Think 1.2p to 4p.

• A 60,000‑word novel at 1.2p lands near £720. At 4p, around £2,400.
• A 90,000‑word novel at 1.2p lands near £1,080. At 4p, around £3,600.
• A 120,000‑word epic at 1.2p lands near £1,440. At 4p, around £4,800.

Lower end suits clean, straightforward manuscripts. Upper end suits complex projects or senior editors with deep genre expertise.

Quick calculator:

1. Write your final word count.
2. Multiply by 0.012 for a low estimate.
3. Multiply by 0.04 for a high estimate.
4. Note any VAT on top if your editor is VAT‑registered.

Hourly rates

Common hourly ranges sit between £35 and £80+. Many editors quote a project fee instead, which protects your budget and keeps scope clear. Hourly suits coaching or open‑ended diagnostics. If you go hourly, ask for a cap and a progress checkpoint.

Project examples for a full developmental edit

These totals usually include an editorial letter plus margin comments. Scope varies by editor, so confirm inclusions.

• 50–60k words, roughly £900 to £2,200
• 70–90k words, roughly £1,200 to £3,500
• 100–120k words or complex SFF or narrative nonfiction, roughly £2,000 to £5,000+
• 150k+ or research‑heavy work, £3,500 to £6,500+

A quick scenario. Two 80k manuscripts arrive. One is a tight single‑POV thriller, ready for sharpening. The other juggles four narrators, a braided timeline, and heavy sources. Same length, different workload, different fee.

Manuscript assessment

Diagnostic letter only, no margin comments. Faster, cheaper, high value for early structural checks. For 70–90k words, expect roughly £500 to £1,500. Many writers start here, revise, then book a lighter full dev edit.

Add‑ons and premiums

• Second pass, often 30 to 50 percent of the original fee
• Rush fees, often 20 to 40 percent for tight turnarounds
• Debrief or coaching calls beyond the first, billed hourly or as a small fixed add‑on

Plan for payment terms too. Deposits of 30 to 50 percent are common, with the balance on delivery or a milestone.

Market notes

CIEP members often align with or exceed suggested minimums. Editors on platforms such as Reedsy often sit at the higher end, especially with strong track records.

If you hire outside the UK, add currency conversion and processing fees to your budget. For UK‑based, ask whether VAT applies. Clear paperwork helps, which includes a contract with scope, dates, and deliverables.

How to use these ranges well

• Price your exact word count, not a guess.
• Place your project on the spectrum. Clean single‑POV work tends to sit lower. Complex structures, heavy research, or senior expertise push higher.
• Compare like‑for‑like packages. Editorial letter only versus letter plus comments and a call will not match.
• Ask for a written, fixed‑scope quote. Word‑count cap, deliverables, number of passes, timeline, and response window for follow‑up questions.

Do this legwork and you avoid surprise invoices. More important, you match the right level of edit to the stage you are in, which saves both money and momentum.

Pricing Models and What’s Included

Editors price work in three main ways. Pick a model which fits your budget and temperament. Clarity beats surprise every time.

Per project

Fixed fee linked to word count and agreed deliverables. Good for budgeting and scope control. You know the total before work begins, and scope stays stable.

What to expect:

• A word count cap.
• A list of deliverables.
• A clear timeline.
• A note on out‑of‑scope requests and how changes get priced.

A mini example. An 85,000‑word thriller. Quote states one editorial letter, margin comments, a debrief call, and a word count cap of 87,000. If your revision grows to 92,000, expect a change order before work continues.

Per word

Transparent and easy to compare across editors. Multiply your final word count by the quoted rate, then check whether VAT sits on top.

This model often suits full reads where scope feels standard. Use a range for planning, then pin down a fixed number in the contract.

Quick maths:

• Final word count x low rate.
• Final word count x high rate.
• Add VAT if your editor is VAT‑registered.

Per hour

Best for coaching or open‑ended diagnostics. Flexible, which helps when goals evolve during revision. Ask for an estimate, a cap, and a midpoint check.

A simple setup:

• 4 hours for a sample read and notes.
• 1 hour for a call.
• 3 hours for follow‑up reads.

Agree on a ceiling before work starts, then request a time log with brief notes on tasks.

Typical inclusions in a developmental edit

• Editorial letter. Often 5 to 20 pages. Focus on structure, arc, stakes, POV, narrative drive, and chapter order. Expect priorities, not a line‑by‑line.
• Margin comments. Targeted notes inside the document. Examples include scene purpose, tension, character motivation, and continuity checks.
• High‑level book map or reverse outline. A chapter grid with plot beats, POV, word counts, and timeline markers. Useful for reshaping scenes and pacing.
• Debrief call. Thirty to sixty minutes to set a revision plan. Bring three questions which matter most.

A sample margin note you might see:

• “Scene goal unclear. Protagonist enters wanting X, exits without a change. Either raise a complication or cut and fold the one fresh detail into the next scene.”

Often excluded or priced separately

• Line editing and stylistic work.
• Copyediting and proofreading.
• Sensitivity reading.
• Fact checking and permissions.
• Indexing and reference formatting.
• Detailed source verification for narrative nonfiction.

Developmental work stays big picture. Language polishing and final checks follow later, once structure holds firm.

Payment terms

Most editors request a deposit to book the slot. Commonly 30 to 50 percent. Balance on delivery or by milestones. Instalments are possible with longer schedules.

Missed deadlines and scope changes affect timing and price. If life happens, talk early. A quick email often preserves goodwill and the booking.

VAT and paperwork

UK editors who are VAT‑registered add 20 percent VAT. Ask whether the quote includes VAT or lists VAT separately. For international payments, factor in processing fees and currency conversion.

Request a clear contract. Look for:

• Scope and deliverables.
• Number of passes and response windows for follow‑up questions.
• Word count cap and what triggers a change order.
• Timeline, start date, and delivery date.
• File formats and version names.
• Confidentiality and IP ownership.
• Cancellation, refunds, and dispute steps.

File basics. Word with Track Changes remains standard for margin comments. Google Docs works for coaching and short samples. PDFs make structural work harder, so best reserved for assessments only.

A quick way to lock scope

Build a one‑page scope table and attach it to the contract.

Include:

• Word count cap.
• Deliverables, with page ranges for the letter.
• One or two passes, plus what a second pass covers.
• One debrief call, with length and recording policy.
• Timeline with calendar dates.
• Exclusions, listed plainly.
• Post‑delivery support window, for example email questions for two weeks.

This table drives clarity. You know what arrives, when it arrives, and how changes get handled. Editors like clarity too, which means fewer surprises and cleaner work on both sides.

How to Get Accurate Quotes and Compare Editors

Quotes are only as good as the brief. Give editors the right material, and you get clear scopes and firm prices. Vagueness invites padding.

Build a tight quote pack

Send one email with everything an editor needs to price with confidence.

Include:

• Final word count. No estimates.
• Genre and category. Thriller, high fantasy, memoir, prescriptive business, and so on.
• Target reader. Age band, niche, or market segment.
• Comparable titles. Three is plenty, with a note on why those comps.
• A short synopsis. One to two paragraphs covering setup, stakes, and outcome.
• Top three goals or questions. Examples: pace sags in the middle. Dual timeline feels muddy. Unsure about POV choices.

A short template you can paste:

Subject: Dev edit quote request, 88k-word memoir, September start

Hello [Name],

Manuscript length: 88,000 words
Genre: Memoir, grief and resilience
Target reader: Adults 25–55, readers of H is for Hawk and The Salt Path
Comps: A Manual for Heartache, When Breath Becomes Air, The Last Act of Love
Synopsis: [Paste 6–8 sentences]
Goals: 1) Structure and pacing. 2) Voice consistency. 3) Chapter order, especially Part Two.

Hoping for an editorial letter plus margin comments and a debrief call. Flexible on start date within September. Please confirm availability, scope, total fee, VAT status, and timeline.

Best,
[Your name]

Send a clean sample

Editors price based on what shows up on the page. Help the process.

• Provide the first 3,000 to 5,000 words. Add a contents page or outline for longer works.
• Remove tracked changes and comments from older rounds.
• Standard file formats only. Word .docx suits margin comments best.
• Ask about a paid sample diagnostic. A short, focused read on 2,000 words often reveals fit and feedback style.

Compare like for like

Quotes vary because scopes vary. Standardise before judging value.

Confirm:

• Editorial letter length or range.
• Margin comments included or excluded.
• A book map or reverse outline included or excluded.
• One debrief call, with length stated.
• A second pass included or priced as an add‑on.
• Response window for follow‑up questions, for example two weeks by email.
• Word count cap and change‑order policy.
• VAT included in the total or added on top.

A quick spreadsheet helps. Columns for fee, VAT, deliverables, timeline, second pass, follow‑up policy, and notes on tone. Score each quote for value, not price alone.

Check credentials and fit

Experience matters, but relevance matters more.

• Memberships. CIEP membership suggests training and a code of practice.
• Genre match. Ask for recent projects near your category.
• Testimonials with names or links.
• Portfolio pages or case studies.
• Publishing background. Agenting, in‑house editing, or robust freelance track record.
• Alignment with your route. Self‑publishing, hybrid, or traditional submission.

Two quick questions to send:

• What strengths do you see in the sample, and where would you focus first?
• Which two risks threaten this project, and how would you reduce those risks?

Clarity in answers signals a strong partner.

Assess communication style

Price fades if collaboration feels rough. Watch for:

• Direct, specific comments rather than airy generalities.
• Prioritised action steps, not laundry lists.
• Realistic timelines, with room for thinking and revision.
• Professional boundaries. An editor who says no when scope drifts protects your budget.

A short test during a call:

• Ask for one diagnostic on a sample scene. For example, “Does Chapter Two move the goal forward?” Listen for a concrete answer with a why and a next step.

Spot red flags

Walk away from:

• Vague deliverables. Phrases like “full feedback” without specifics.
• “Unlimited revisions.” Boundaries matter in editorial work.
• No contract or no mention of VAT where relevant.
• Guaranteed agent offers or bestseller talk.
• Prices far below market norms for full structural work.
• Pressure to start tomorrow with no schedule discussion.

How many quotes, and when to book

Gather two to four quotes. Enough for contrast, not enough to stall momentum. Editors book weeks ahead. Early contact secures a slot and saves rush premiums.

A quick checklist for your inbox

Before replying yes to a quote, confirm:

• Total fee, plus VAT status.
• Deliverables in plain language.
• Number of passes.
• Word count cap.
• Timeline with start and delivery dates.
• Debrief call length and recording policy.
• Follow‑up window for questions.
• Payment plan, deposit amount, and refund terms.
• File format and naming conventions.
• Confidentiality and IP ownership.

Strong briefs earn strong quotes. Strong quotes lead to focused work and fewer surprises. That means more energy for the pages that matter.

Budget-Savvy Options Without Sacrificing Quality

Smart writers get good editorial help without emptying their bank accounts. The trick is timing and staging the work.

Start with a manuscript assessment

Think diagnosis before surgery. A manuscript assessment gives you a structural report for £500 to £1,500, roughly half the cost of a full developmental edit.

You get an editorial letter covering plot architecture, character development, pacing issues, and market positioning. No margin comments or line-by-line notes. The editor reads your entire manuscript and delivers a roadmap for revision.

Apply those changes yourself. Fix the big structural problems. Then, if you need it, book a lighter developmental edit focused on refinement rather than major reconstruction. Two smaller bills often hurt less than one large one.

Try a partial or deep-dive edit

Target your biggest weakness instead of paying for comprehensive coverage.

Option one: first 50 to 80 pages plus your chapter outline. An editor works through your opening structure, character introductions, world-building setup, and plot trajectory. You get detailed feedback on the foundation that supports everything else.

Option two: focus on your problem middle. Send chapters 8 through 15 if that's where momentum dies. Get targeted help on the specific pages that need the most work.

Both approaches cost 60 to 70% less than a full manuscript edit. You learn the editorial approach and voice. Then decide whether to continue or tackle the remaining revision solo.

Use a coaching model

Monthly calls plus rolling chapter reviews spread the cost over time and keep momentum strong.

Here's how it works: you submit 20 to 30 pages every month. The editor provides written feedback plus a 45-minute call to discuss priorities and next steps. You revise those chapters, then move forward to the next batch.

Timeline: six to eight months for a full novel. Cost: £200 to £400 per month instead of £2,000 to £4,000 upfront. Bonus: you learn editorial thinking while writing and revising.

Perfect for writers juggling other commitments or building their revision skills alongside project completion.

Do your homework first

Preparation cuts editorial time and cost.

Create a reverse outline. List what happens in each chapter, focusing on plot progression and character change. Gaps become obvious. Redundant scenes stick out. An editor spends less time mapping basic structure when you arrive with a clear overview.

Cut 5 to 10% of your word count before the edit. Look for repetitive dialogue tags, unnecessary backstory dumps, and scenes that duplicate emotional beats. Trimming obvious bloat means the editor focuses on deeper structural issues.

Fix known problems. That subplot you know doesn't work? That character who disappears for 40 pages? Address the obvious gaps before paying someone to point them out.

Create a style sheet. List character names, place names, terminology, and timeline markers. Consistency errors distract from bigger developmental feedback.

Get targeted feedback from other sources first

Beta readers surface some issues for free. Sensitivity readers catch representation problems before your editor sees the manuscript. Writer friends spot unclear passages or confusing dialogue.

Reserve your editorial budget for high-impact structural work. An editor shouldn't be the first person to tell you the romance subplot feels forced or the villain lacks motivation.

Three good beta readers cost you nothing but acknowledgment credit. One developmental editor costs £1,500 to £3,000. Do the math.

Plan your finances strategically

Many editors offer payment plans. Ask about splitting the fee into three or four instalments over the project timeline.

Look into arts funding. Regional arts councils sometimes offer development grants for writers. Writing organizations run scheme competitions with editorial services as prizes. The Literature Wales bursary scheme and Arts Council England grants cover editorial costs for qualifying projects.

Check with local libraries and writing centres. Some run subsidized editorial programmes or partner with editors for reduced-rate services.

Use timing as leverage

Rush jobs cost extra. Flexible deadlines save money.

Book your slot two to three months ahead with a loose start window. Editors appreciate writers who accommodate their schedule peaks and valleys. That flexibility often translates to better rates and more attention to your project.

Avoid December bookings if your manuscript is ready in October. Holiday pressure pricing kicks in. Wait for January availability and save 20 to 30%.

Keep your scope stable. Change orders cost money and time. Define your needs clearly and stick to the agreed deliverables.

The two-stage strategy

Here's the most cost-effective approach for serious revisions:

Stage one: manuscript assessment now. Get the structural diagnosis and create a revision plan. Budget: £500 to £1,200.

Stage two: developmental edit after your revisions. Focus on polishing and refinement rather than major reconstruction. Budget: £800 to £2,000 for targeted work on a stronger draft.

Total saving compared to a full developmental edit on a rough draft: £500 to £1,500. Plus you learn revision skills and arrive at your final draft faster.

The goal isn't finding the cheapest editor. The goal is getting the editorial help you need without financial stress derailing your writing goals. Smart staging and preparation make professional editing affordable for more writers.
