A practical, step-by-step guide to finding the right literary agent for your children’s book
Finding a literary agent is not a lottery, even though it often feels like one. It is a research process followed by a writing process followed by a waiting process, and the writers who approach it systematically do better than those who approach it as a numbers game. Here are some guidelines you might find useful.
Do you really need an agent?
Before starting the agent search, it is worth asking whether you need one. For the major UK children’s publishers, likePenguin Random House, HarperCollins, Hachette, Macmillan, and most of their imprints, yes, an agent is required. These publishers do not accept unsolicited submissions, so an agent is your only route in.
For smaller independent publishers, many of whom accept direct submissions, an agent is not always necessary. See our regularly updated list of UK publishers currently accepting unsolicited manuscripts. If you’re happy to publish with small independent press, submitting directly may be a faster and equally effective route. See our article on UK publishers currently accepting unsolicited manuscripts for more on this.
(Just note that if you want someone to negotiate your contract, manage your rights, and advocate for your career long-term, having an agent is the way to go, even if you’re happy to publish with the smaller publishers.)
What a children’s book agent actually does
A literary agent is not just a gatekeeper. A good agent is an editorial partner, a career strategist, a contract negotiator, and an advocate. They read your manuscript before submission and often suggest revisions. They know which editors at which publishers are actively looking for what. They submit on your behalf to multiple publishers simultaneously. They negotiate your advance and your contract terms. They manage subsidiary rights for translation, audio, or film. And they take a percentage of everything they earn for you, which means that you lose part of your earnings, but also that their incentive is entirely aligned with yours.
Finding agents to query
There are several reliable ways to build a list of agents to approach. The most useful starting points are dedicated agent databases, annual publishing directories, and agents’ own social media presence. Many UK children’s book agents are active on Instagram and X, and following them gives you a good sense of their taste and current interests before you submit.
Useful resources:
- QueryManager – a free database where agents list their submission guidelines and current status (open or closed)
- Publishers Marketplace – a comprehensive industry database with agent listings, recent deals, and genre filters; has a paid subscription tier with fuller access
- The Writers’ & Artists’ Yearbook – published annually by Bloomsbury, lists UK agents with submission guidelines and representation notes; the online version is updated more frequently than the print edition
- Manuscript Wishlist (mswishlist.com) – agents post what they are actively looking for; if an agent’s wishlist describes your book, that’s warm territory worth prioritising
Finding the right agent for your book
Not all agents are the right agents for you, and querying widely without thinking carefully about fit might waste your time. Start by filtering for agents who specifically represent children’s books, and then go further. A children’s agent who primarily handles middle grade and YA is not automatically the right match for a picture book, even if picture books are technically within their remit. Look at the authors they already represent, the books they’ve recently sold, and any interviews or social media posts where they describe what they’re looking for. You are trying to find an agent whose existing list feels like a neighbourhood your book could live in, one whose taste and interests align nicely with what you’re writing.
What agents want to see
Submission requirements vary by agent, so always read the guidelines on their website before sending anything. That said, the standard for children’s book submissions in the UK is broadly as follows:
- For picture books, most agents ask for the complete text. Include a brief cover letter and a synopsis if requested, but the full text should always be included.
- For middle grade and young adult fiction, most agents ask the first few chapters (generally three), though some agents specify a word count instead.
- In both cases, the cover letter is your first impression. Keep it to one page, lead with the book rather than yourself, and include the title, age range, genre, and word count. See our full guide to writing a query letter for children’s books for more detail on how to approach it.
Keeping track
Approach your agent search in a methodical way. Keep a running database, like a list or a simple spreadsheet, with each agent’s name, agency, submission guidelines, current status, what they represent, and when you submitted. Note anything specific that made them seem like a good fit. Track responses as they come in. The agent search can stretch over months or longer, and having a clear record prevents you from losing track, submitting twice to the same agent, or missing a response window.
What to expect after submitting
Response times vary enormously. Some agents respond within weeks and others take six months or longer. Most agents operate a “no response means no” policy, so if you haven’t heard after the stated response window, assume it’s a pass and move on.
If you do get a tentatively positive response, it’s not necessarily a confirmed deal. If you get a full manuscript request it’s not an offer of representation yet. It means the agent was interested enough to read more. It could lead to an offer, of course, but you’re not there yet. A call or meeting with an agent is not an offer of representation either. Some agents have “revise and resubmit” conversations, which means they might want to review things before committing.
And obviously this relationship needs to work for both parties. You need to be happy with what the agent has to offer, too. Make sure you like what the agent has to say and what they have to offer you. And if you have multiple offers (a lucky position!), make sure to review the various options properly. Take the time to speak with each agent before deciding.
Finding a children’s book agent: dos and don’ts
Do
- Research each agent carefully before submitting; look at their existing list, recent deals, and what they’ve said publicly about what they’re looking for
- Filter specifically for agents who represent your category and age group, not just children’s books generally
- Keep a methodical database of every agent you query, with submission dates, requirements, and responses
- Read each agent’s submission guidelines before sending anything, as requirements vary and ignoring them is an immediate strike against you
- Personalise your query briefly – one sentence explaining why you’re approaching this specific agent is noticed
- Submit simultaneously to multiple agents; it’s expected and you should say so in your cover letter
- Keep writing while you query, because the process is long and having a second project in progress is good for your sanity
- When you receive an offer, notify other agents who have your manuscript before accepting
Don’t
- Query agents who don’t represent your category or age group
- Send a generic, unpersonalised mass submission
- Submit before your manuscript is as polished as it can be
- Mistake a full manuscript request for an offer of representation – it’s encouraging, but it’s not a yes
- Accept an offer of representation without speaking to the agent properly first
- Stop querying after a run of rejections, as one agent’s pass is not a verdict on your book
- Query the same agent twice with the same manuscript
- Assume that finding an agent quickly means the book will sell quickly; note that submission to publishers is a separate and equally unpredictable process
- Expect it to be a quick process; finding an agent takes most writers longer than they expect
