Most writers spend years on a manuscript and an afternoon on the letter that decides whether anyone reads it. That imbalance is understandable — the novel is the work, the query is admin. But in UK publishing, the covering letter is often the only sample of your writing an agent sees before they open your chapters. It deserves more than a rushed hour on a Sunday evening.
Generic submissions get generic responses. Before you write a word, build a shortlist of eight to twelve agents who genuinely represent what you have written.
Where to look: agency websites are the primary source, and most list their authors, their tastes and their submission guidelines. The acknowledgements pages of recently published books in your genre will name the agent who sold them. The Writers' & Artists' Yearbook remains a reliable directory, and literary festivals and writing conferences often publish agent profiles. If an agent posts their wish list publicly, read it properly — it tells you what they are hungry for right now.
Then check two things for each name. First, are they open to submissions, and if so, through what route? Second, does their list contain books that sit on the same shelf as yours? A crime agent will not take your literary memoir, however good it is. Sending it anyway costs you a name you might need later.
British agents expect a covering letter in the body of an email, with your sample pages attached as a separate document, unless the guidelines say otherwise. Keep the letter to one page — roughly 250 to 350 words — and cover four things:
Two details trip up first-timers. State your word count accurately — 89,000 is fine, "approximately 120k" in a debut is often a problem before anyone has read a line. And finish the manuscript. A half-drafted novel with a brilliant opening chapter still reads as a risk to most agents.
Use this as scaffolding, not as a script. Your voice should be recognisable in the pitch paragraph; that paragraph is the only evidence of your prose style in the letter itself.
Dear [Agent name],
I am writing to seek representation for [Title], a [genre] novel of [word count] words. I am approaching you because you represent [Author name], whose work shares [specific quality] with mine. [One further sentence if you have a genuine connection — a course, a festival, a referral.]
[Title] is set in [place and time]. When [inciting event], [protagonist] must [central problem], or risk [what is at stake]. It will appeal to readers of [two recent comparable titles] and explores [thematic hook].
I have [credential, publication, prize, or simply: not previously published]. I live in [city] and work as [profession]. [Title] is complete, and I am ready to send the full manuscript on request.
Thank you for your time and consideration.
Yours sincerely,
[Name]
[Email and phone]
Note the tone: courteous, factual, no exclamation marks. British submissions tend to be more restrained than American ones, where a punchier hook is expected. Do not apologise for taking up their time, and do not describe your book as unputdownable. Let the pitch do that work.
Most UK agencies ask for a synopsis of one page, sometimes two, occasionally 500 words. Follow the stated length exactly — it is a small test of whether you read instructions.
Write it in third person, present tense, and include the ending. Yes, the real ending. A synopsis that trails off with "and she must decide what truly matters" tells an agent you have not finished thinking the book through. Cover the main character, the central conflict, the major turning points and how it resolves.
Keep names to three or four. Do not include subplot detail that never pays off, and do not write it as a blurb — a blurb teases, a synopsis explains. Format it plainly: title, genre, word count at the top, single-spaced, no headings within the text.
Publishing is a small industry, and courtesy travels. The writers who get remembered warmly are rarely the ones with the best hooks; they are the ones who made an agent's job easier.
Agents receive far more submissions than they can answer personally. A form rejection is not a verdict on your ability; it usually means the book was not right for that list. If feedback does come, take it seriously but remember it is one reader's opinion.
If the guidelines say eight weeks, wait twelve before a brief, polite enquiry. Then move on. Do not resubmit the same project to the same agent after a rejection unless they invited you to, and do not send a revised draft as a fresh submission — it rarely lands well.
Give yourself a deadline and work through it in order.
Send three, wait, and send three more. The letter gets better with each attempt, and the writers who find representation are usually the ones who kept a tidy spreadsheet and kept going.
