Author guide
There is no single "right" way to publish a children's book, only the route that fits your book, your budget and how much of the work you want to do yourself. This is the honest overview: the real options, what each one costs, the basics of ISBNs and formats, and what actually happens after your book is on sale.
For the genre-agnostic overview whatever you write, see how to self-publish a book in the UK.
There are four main routes to publish a children's book in the UK: traditional publishing, do-it-yourself self-publishing, paid hybrid or assisted publishing, and the newer £0-upfront launchpad model, differing mainly in upfront cost and who does the work.
Almost every path to publishing a children's book is a version of one of these four. They differ most in two things: what you pay up front, and who does the work of getting the book made and read.
Publishing a children's book in the UK can cost from close to £0, doing everything yourself with a free platform ISBN, to several thousand pounds if you pay professionals; illustration is usually the largest expense.
The figures below are indicative UK ranges at the time of writing. Every book is different, so treat them as a starting point for getting your own quotes, not a price list.
So the honest range is wide: from close to £0 if you do everything yourself and lean on a free platform ISBN, to several thousand pounds if you pay professionals for every step. The launchpad route is designed to remove that up-front cost entirely.

An ISBN is the unique number identifying one edition of a book, and each format needs its own, so a paperback, hardback and ebook are three ISBNs; free platform ISBNs work but tie the book to that platform.
An ISBN is the unique number that identifies one edition of one book to shops, libraries and wholesalers. The key rule: each format needs its own ISBN, so a paperback, a hardback and an ebook are three ISBNs. A free ISBN from a platform such as KDP works, but it records that platform as the publisher of record and is best kept to that platform. Buying your own ISBNs (in the UK, from Nielsen) lets the same edition be sold and reordered across many shops and wholesalers under your own imprint. For a children's book the format choice also shapes the reader experience: hardbacks suit gifting and library sales, paperbacks suit price-sensitive buyers, and an ebook widens reach where children read on screens.
After you publish, the work that decides whether a children's book finds readers begins: an accurate listing, early reviews, reaching the grown-ups who buy children's books, and, where it fits, paid promotion and trade supply into bookshops.
Uploading a file is the easy part. The work that decides whether a children's book finds readers is everything after it: an accurate, keyword-aware listing; getting early reviews from real readers; reaching the grown-ups who buy children's books, through the shops, schools, libraries and online channels where they already are; and, where it fits, paid promotion and trade supply into bookshops. Bookshop placement in particular is never guaranteed: shops choose what they stock, and the realistic route is trade-orderable supply on the terms shops expect. No honest publisher, of any kind, can promise your book will sell. What a good launch can do is make sure the book is genuinely reachable by the readers most likely to want it, and measure what is working so effort goes where it pays.
Traditional publishing, if accepted, usually takes a year or two; the do-it-yourself and launchpad routes can put a book on sale within weeks once the manuscript is edited, illustrations are sorted, and the format is chosen.
Timelines vary as much as costs. Traditional publishing, if you are accepted, is usually the slowest, often a year or two from a signed deal to a finished book. The do-it-yourself and launchpad routes can put a book on sale within weeks once the manuscript is ready. Whichever route you choose, the same groundwork pays off: a finished, edited manuscript; a clear sense of the reading age and format you are aiming for; any illustrations sorted or budgeted; and a short, honest description of the book and who it is for. Having those in hand makes every later step, from cover to listing to launch, faster and cheaper. It also lets you compare quotes and routes on equal terms, rather than committing to the first offer you see.
Choose by your priorities: submit to agents for a traditional imprint if you can wait; self-publish for full control; or pick the launchpad model to pay nothing upfront and have the launch run for you.
If your priority is a traditional imprint and you are willing to wait and to be turned down, submit to agents and publishers. If you want full control and are happy to run every step yourself, self-publishing is the most flexible. If you would rather not pay up front and want someone to run the launch for you in exchange for a share of sales, the launchpad model is worth a look. None of these is "best" in the abstract; the right one depends on your time, your budget and how much of the work you want to own.
FossPress runs the launchpad route: nothing to pay up front, we set up, publish and launch your book across every channel in parallel, and earn a share of the sales, so we only win when you do.
FossPress runs the launchpad route. There is nothing to pay up front: we set the book up, publish it, and run the launch across every channel in parallel, and we earn a share of the sales we drive, so we only win when your book does. You keep writing; we run the channels and show you what is happening in one live dashboard. You can see how our own titles are performing on our performance page, which reports real numbers rather than promises. If that sounds right for your book, you can start on the author portal.
There are four main routes: traditional publishing through an agent, do-it-yourself self-publishing, paid hybrid publishing, and the newer £0-upfront launchpad model where a partner runs your launch for a share of sales. Which fits depends on your budget and how much work you want to do.
You can publish for close to £0 by doing everything yourself on a free platform like Amazon KDP, but you still pay for editing, illustration and a cover. On the launchpad model, such as FossPress, there is £0 upfront and the publisher earns only a share of sales.
Not always: platforms such as Amazon KDP give you a free ISBN, but it ties the book to that platform. Buying your own ISBNs from Nielsen lets the same edition sell across many shops under your own imprint. Each format, paperback, hardback and ebook, needs its own ISBN.
A partner publishes and launches your book with nothing to pay upfront and earns an agreed share of sales instead, so they only earn when you do. FossPress runs it on 15% rev-share: copyright stays yours, book rights licensed for the term, costs recouped from sales.
