Uploading a book to KDP (Kindle Direct Publishing) is the final step in the self-publishing process where you submit your formatted manuscript, cover file, and book metadata to Amazon for publication. The upload process involves seven steps: creating a KDP account (with UK tax interview and bank details for GBP royalty payments), starting a new title, entering metadata (title, subtitle, author name, description, up to 7 keywords, and up to 3 categories), uploading your manuscript file (PDF for paperback, EPUB or DOCX for Kindle), uploading your cover file, configuring ISBN and publication details, and setting your price and royalty preferences. KDP's automated review typically takes 24 to 72 hours. Common upload failures include incorrect PDF page dimensions, missing embedded fonts, cover file dimensions not matching the manuscript's trim size and page count, and metadata that violates Amazon's content guidelines. This walkthrough covers every screen and field in the KDP upload process, with specific guidance for UK authors on ISBN options, pricing in GBP, and tax configuration.

Uploading a book to Amazon’s Kindle Direct Publishing (KDP) platform is often painted as a simple, straightforward process. However, for UK authors, the reality is far more nuanced — a complex maze of technical files, regional pricing strategies, tax forms, ISBN ownership decisions, and formatting challenges.
I know this intimately. When I was formatting Google. Panic. Repeat., writing the book was the easier part. The real ordeal was wrestling with the KDP upload process itself. Despite my technical background and 25 years in digital business, I spent countless hours untangling file problems, navigating Amazon’s US-centric platform, and figuring out how to price my book correctly for UK buyers. This experience exposed just how archaic and headache-inducing the self-publishing process can be, even for seasoned professionals.
This article is a no-nonsense, UK-focused guide that goes well beyond the basic upload steps. It covers everything from terminology, real GBP cost breakdowns, UK tax and VAT insights, to expert tips drawn from my experience running MrPrime.com (an Amazon growth agency) and co-owning LoveReading.co.uk, the UK’s largest book review platform. Whether you’re a first-time self-publisher or looking to streamline your workflow, this walkthrough will give you the clarity you need to avoid common pitfalls and get your book live on Amazon UK efficiently and professionally.
Before you dive into the upload process, it’s crucial to understand the publishing landscape and the terminology involved—especially from a UK perspective. KDP is Amazon’s self-publishing platform, enabling authors to publish eBooks and print-on-demand paperbacks globally. However, as a UK author, there are nuances that impact your rights.
You should have ready:
- Manuscript File: Usually a formatted Word DOCX or EPUB for eBooks; a print-ready PDF for paperbacks. KDP has strict formatting requirements, and getting these right is essential to avoid rejection. From my experience, poorly formatted manuscripts are the number one cause of delays and frustration.
- Cover File: Separate high-resolution cover images for eBooks and print books. Print covers are more complex—they include spine and back cover elements.
- ISBN: Amazon offers free ISBNs, but these list Amazon as publisher, not you. UK authors can purchase their own ISBNs through Nielsen Book Services (£93 each or £174 for 10). Owning your ISBN means you retain full publishing rights and control.
- Pricing and Royalty Options: KDP offers 35% or 70% royalty rates depending on price, book type, and territory. Pricing must be set correctly in GBP for UK sales.
- Tax Information: UK authors must complete a W-8BEN form to certify non-US status and avoid 30% withholding. VAT applies differently to eBooks (20%) and print books (zero-rated).
- Metadata: Book title, subtitle, description, keywords details are essential for discoverability on Amazon UK.
Uploading your book takes patience and precision. Here is a detailed breakdown of each step, with exact menu paths and practical tips to avoid errors.
Step 1: Set Up Your KDP Account
- Visit kdp.amazon.co.uk.
- Sign in with your existing Amazon account or create a new one dedicated to publishing.
- Navigate to Your Account > Account Settings to complete your profile:
- Enter your UK bank details for royalty payments (sort code/account number).
- Complete the tax interview: select the UK as your country and fill out the IRS W-8BEN form online. This step is crucial to avoid high US tax withholding.
- Double-check your email and contact details for notifications.
Step 2: Create a New Title
- From your KDP dashboard, click “Create New Title”.
- Choose between “Kindle eBook” or “Paperback” (print-on-demand). Note: You can publish both formats separately, but each requires its own upload.
- Name your project clearly to avoid confusion if you have multiple titles.
Step 3: Enter Your Book Details (Metadata)
- Book Title and Subtitle: Enter your exact book title without keyword stuffing. UK readers tend to appreciate clarity over gimmicks.
- Series Information: If applicable, add the series name and volume number. This helps readers navigate series order.
- Edition Number: Use if this is a revised edition.
- Author Name: Use your consistent pen or business name. Avoid changing this between books to build brand recognition.
- Contributors: Add editors, illustrators, translators when relevant.
- Book Description: This is your sales pitch. Use HTML tags like
<b>and<i>to add formatting. Keep it concise but compelling. UK readers respond well to straightforward, well-edited descriptions. - Publishing Rights: Confirm you hold the copyright (“I own the copyright and hold necessary publishing rights” is the most common choice).
Step 4: Upload Manuscript and Cover
- Manuscript Upload:
- For eBooks, upload DOCX or EPUB files. I recommend EPUB for best formatting control, but DOCX is acceptable if formatted properly.
- For paperbacks, upload a print-ready PDF matching your selected trim size (e.g., 198 x 129 mm is a popular UK trade paperback size). Include proper margins fonts.
- Cover Upload:
- For eBooks, upload a high-resolution JPEG or TIFF cover image (minimum 1000 pixels width, 2560 recommended).
- For paperbacks, upload a full cover PDF including front cover. KDP’s Cover Creator can help if you don’t have a finished cover.
- Preview Your Book: Use KDP’s online previewer to review your manuscript and cover on desktop and mobile views. Check for formatting glitches, image quality, and page breaks.
Step 5: ISBN and Publication Details
- For paperbacks, either:
- Use a free KDP ISBN (Amazon listed as publisher), or
- Enter your own Nielsen-purchased ISBN to retain your publishing imprint.
- Select Print Options: trim size, paper type (white or cream), bleed settings, and cover finish (matte or gloss).
- Confirm Print Cost shown matches your expectations.
Step 6: Pricing and Distribution
- Set your Royalty Plan:
- For eBooks, 70% royalty applies if priced between £1.99 and £9.99 (GBP), subject to delivery costs. Otherwise, 35%.
- For paperbacks, royalties are 60% of list price minus printing costs.
- Set your List Price in GBP.
- Choose distribution channels — Amazon UK. UK authors often focus on Amazon.co.uk but consider global reach if your content has wider appeal.
- Note that VAT applies to eBooks (20% included in royalty calculations) but is zero-rated on print books sold in the UK.
Step 7: Publish Your Book
- Review all inputs carefully.
- Click “Publish Your Kindle eBook” or “Publish Your Paperback Book”.
- Amazon usually processes and publishes within 24 to 72 hours. You will receive an email confirmation when live.
The majority of KDP guides are US-centric, overlooking critical UK-specific factors that significantly impact your publishing success and compliance.
ISBNs and Publisher Identity
In the UK, ISBNs are exclusively purchased through Nielsen Book Services. A single ISBN costs £93, and a block of 10 costs £174. While KDP offers free ISBNs, these list Amazon as the publisher, which can limit your control over your book’s identity sales outside Amazon.
My own experience: Early in my self-publishing journey, I used free KDP ISBNs for my print books. When I tried to sell wholesale or offer my books to UK bookshops, the Amazon imprint confused buyers and limited opportunities. I had to purchase my own ISBNs and reupload, causing unnecessary delays and costs.
If you intend to build a brand or publish multiple titles, investing in your own ISBN block is a wise business decision.
Pricing and Currency Considerations
Set all your prices in GBP for the UK market. This may seem obvious, but KDP defaults to USD and other currencies depending on your setup.
- Ebooks: The 70% royalty option applies only if priced between £1.99 and £9.99. Pricing outside this range drops royalties to 35%.
- Print Books: Printing costs are deducted from royalties. For example, a 200-page black-and-white paperback costs around £2.40 to print per copy. Set your list price accordingly to maintain a healthy margin.
- VAT: Print books are zero-rated for VAT in the UK, so no VAT is added. However, eBooks are subject to 20% VAT, which Amazon includes in royalties. This explains why you might see a slightly lower payout on eBook sales.
Tax Implications for UK Authors
KDP is a US company, so US tax rules apply. UK authors must:
- Complete the IRS Form W-8BEN via the KDP dashboard (Account Settings > Tax Information). This certifies you as a non-US person and reduces withholding tax from 30% to 0% on royalties.
- Submit this form as soon as you set up your account to avoid excessive tax deductions.
- Declare your KDP income to HM Revenue & Customs (HMRC) as self-employed or business income.
- Consider VAT implications — if you sell over the VAT registration threshold (£85,000), you may need to register for VAT, although this is uncommon for most authors.
Banking and Payment Schedules
Amazon pays royalties approximately 60 days after the end of the month in which the sale occurred.
Payments are made via direct deposit to your UK bank account—enter these details carefully to avoid delays.
Minimum payout threshold is low (£10 or equivalent).
Keep an eye on currency conversion rates if you receive payments in USD or EUR. UK readers have distinct preferences:
Popular print sizes include 198 x 129 mm (trade paperback) and 210 x 148 mm (A5).
UK readers tend to favour clear British English spelling and grammar—ensure your manuscript matches these standards to avoid alienating your audience.
Genres such as crime-fiction business titles perform strongly.
Metadata should be tailored for UK search terms and categories.
From formatting disasters to tax traps, here are the biggest mistakes UK authors make when uploading to KDP.
Mistake 1: Using Free KDP ISBNs Without Understanding the Implications
Free ISBNs list Amazon as the publisher, which can block you from selling in bookstores or other channels under your own imprint. I made this mistake early on and had to repurchase ISBNs—wasting time and money.
Tip: Purchase your own Nielsen ISBNs if you want full control.
Mistake 2: Uploading Improperly Formatted Manuscripts
KDP rejects files with incorrect margins, missing bleed, or non-embedded fonts. Before building publishing.co. The fix involved learning trim sizes embedding—knowledge that many authors overlook.
Tip: Use professional formatting services like publishing.co.uk or learn KDP’s trim size specs thoroughly before uploading.
Mistake 3: Setting Incorrect Pricing
Pricing your eBook outside the £1.99–£9.99 range forfeits the 70% royalty. Pricing print books too low leaves you with minimal profit after printing costs. Many UK authors also forget to price in GBP or misunderstand VAT implications.
Tip: Research UK market prices for comparable books and set prices strategically.
Mistake 4: Neglecting Tax Forms
Failing to complete the W-8BEN form leads to 30% tax withholding on royalties. Amazon’s tax interview is easy to miss but vital.
Tip: Complete your tax interview immediately after account setup.
Mistake 5: Overlooking Metadata Quality
Generic or keyword-stuffed descriptions reduce discoverability. UK readers favour professionally written descriptions with clear, relevant keywords and categories.
Tip: Spend time crafting metadata tailored for the UK market.

Understanding real-world costs in GBP is essential for budgeting.
| Item | Typical UK Cost | Notes |
|---|---|---|
| Nielsen ISBN | £93 (single), £174 (10) | Owning your ISBN ensures rights and control. |
| Cover Design | £300–£600 | Quality UK designers charge this range. |
| Formatting | £100–£300+ | Professional formatting or automated services. |
| Printing Cost (Paperback) | £2.20–£4.00 per copy | Varies by page count, paper type, and trim size. |
| Amazon KDP Fees | None upfront | Amazon deducts printing cost and takes royalty percentage. |
| Tax Filing / Accounting | £100+ annually | If you engage an accountant for tax purposes. |
Many authors underestimate formatting costs, expecting cheap gigs to suffice. From experience, these often result in unusable files and costly rework. Investing in professional formatting upfront saves time and money.
Comparison With Alternative Publishing Platforms
While KDP dominates self-publishing, UK authors should consider alternatives, especially for print:
| Platform | Strengths | UK-Specific Notes | Costs |
|---|---|---|---|
| KDP | Global reach, print-on-demand, easy upload | Strong UK presence, but US-centric interface | Free upload, printing fees only |
| IngramSpark | Wider print distribution, bookstore access | Better for bookstore sales, but setup fees apply | £49 setup fee + print costs |
| Apple Books | Large ebook market, good for Apple users | No print option, VAT applies | Free upload |
| Draft2Digital | Aggregates to multiple ebook retailers | Supports UK markets, no print | Free upload, royalty share |
| Lulu | Print-on-demand options, global distribution | More print options but higher costs | £25 setup + print costs |
For UK authors serious about print distribution beyond Amazon, IngramSpark is worth considering, despite upfront fees. KDP’s free ISBNs remain US-centric, whereas IngramSpark allows your own ISBNs for better control. However, KDP’s integration with Amazon UK remains unmatched for ease and reach.
