How to Write a Covering Letter for UK Literary Agents: A Step-by-Step Guide

A covering letter is the one part of your submission where you speak directly to the person who might represent you. It is not a formality, and it is not a test of how literary you can sound. It is a short, courteous, specific piece of writing that answers three questions: who you are, what the book is, and why this agent should read it. Get it right and they turn to page one in a good mood. Get it wrong and a perfectly decent manuscript can be set aside before anyone reads a word.

What the covering letter is actually for

Agents read submissions in batches, often at the end of a long day. Your letter is the first thing they see and, quite often, the only part they read in full before deciding whether to carry on. It has three jobs: to show you have done your homework, to describe the book clearly, and to make reading on feel worthwhile.

That is all. Clarity beats cleverness here every time.

Do the groundwork before you type

Most rejections that sting are avoidable. Before you write a sentence, spend twenty minutes on the agent's website.

• Read the submission guidelines and follow them exactly. If they ask for the first three chapters and a synopsis, send precisely that.
• Check which genres they represent. A cosy crime novel sent to an agent who handles business books wastes everyone's time.
• Spell their name correctly, and check how they prefer to be addressed. If the guidelines don't say, use their full name.
• Look at what they have sold recently. A line that shows genuine familiarity – because you have read one of their authors, not because you skimmed a list – is worth more than any flattery.
• Note the right email address, and whether they want the letter pasted into the body of the message or sent as an attachment.

One agency may have several agents. Unless the guidelines say otherwise, approach one of them.

A structure that works

Four short paragraphs will do it. Keep the whole letter to under a page.

Paragraph one: why you are writing

Say what you are submitting and to whom. One or two sentences: "I am writing to submit my debut novel, The Salt Line, for your consideration." If an agent or a published writer suggested you get in touch, mention it here. A genuine referral is worth a sentence.

Paragraph two: the book

This is the heart of the letter. Give the title, genre, word count and a hook that makes the story sound like itself, then add two or three comparable titles published in recent years, ideally ones the agent represents.

A workable version: "The Salt Line is a 92,000-word historical novel set in Whitby in the 1840s, in which a woman who inherits her father's shipping business discovers that his fortune was built on a wreck he caused. It will appeal to readers of [two recent comparable titles]."

Don't summarise the whole plot, and don't end on a rhetorical question. Give them the premise and the stakes, then trust the sample pages to do the rest.

Paragraph three: you

Brief is best. Relevant writing credits, relevant experience, anything that shows you can finish a book and take notes on it. If you have published short stories or been longlisted for a prize, say so plainly. If you have a platform – a newsletter, a career in the subject you are writing about – give it one line. If you have none of that, explain briefly why you wrote this particular book and move on. Being unpublished is not a disqualifier.

Paragraph four: the close

Thank them for their time, list what is attached, and confirm the manuscript is complete and available in full on request. Then stop. No promises about sequels, no jokes, no request for feedback in the first letter.

Tone: confident, plain, and free of apology

Write the way you would to a colleague you respect. Warm, direct, and without hedging.

• Cut the apologies. "I hope you don't mind me emailing", "I know how busy you must be" and "I'm sure this isn't your usual sort of thing" all begin by asking for forgiveness.
• Cut the hype. You cannot know a book will be a bestseller. Say what the book is instead.
• Cut the hedging. "It's sort of a thriller, I suppose" tells an agent you are unsure of your own work. "It's a thriller" does not.
• Cut other people's opinions. Your writing group, your mother and your former English teacher are not the market. A clear premise beats praise.

One exception: noting politely that you are approaching several agents at once is neither rude nor boastful. It is normal, and it is useful information.

Etiquette: the small things agents notice

UK submission etiquette is fairly relaxed, but the conventions are worth respecting.

1. Send the material they ask for, in the format they ask for. If they want a Word document, don't send a PDF. If they want the first 10,000 words, don't send the whole book.
2. Simultaneous submissions are the norm. Unless an agency asks for an exclusive, assume you are expected to be approaching others at the same time. You can agree to a set exclusive period if you are comfortable with it.
3. Write to one agent per agency. Before resubmitting the same project to someone else there, check their guidelines.
4. Keep the letter in the body of the email unless told otherwise. Attachments are usually fine; enormous ones, or a scatter of files, rarely are.
5. Wait for the stated response time before chasing. If it passes with no reply, one short, friendly follow-up is acceptable. Then leave it.
6. Log every submission with the date sent and any stated timeline, so you always know where you stand.
7. If an agent offers representation, tell the others who have your full manuscript and give them a short, reasonable window to respond. Most agents expect this and appreciate the heads-up.

A rejection is not an invitation to argue, and asking for detailed feedback in your first reply rarely ends well. If the agent has given a reason, thank them and move on. Save your energy for the next round.

Before you press send

Read the letter aloud. If you stumble, the agent will too. Check the agent's name, your title and your word count against the manuscript itself. Make sure the last line doesn't trail off into a request for a favour.

Then save a copy, note the date, and close the document. The letter matters, but it is only the door. What lies behind it is the writing you have been doing all along, and the most useful thing you can do now is start the next chapter while you wait for an answer.
