How to Write a Cover Letter UK: The Complete 2026 Guide
If you are learning how to write a cover letter UK employers will actually read, start here: the British cover letter follows its own conventions, and getting them wrong marks you out immediately. It is not simply an American cover letter with the date format changed. From British English spelling to the expected tone, from the one-page rule to what goes in the header, UK recruiters look for a specific shape — and most rejections happen because applicants ignore it. This guide walks through the exact format, the conventions that matter, the length that works, and the mistakes that get applications binned before they are read.
What Makes a UK Cover Letter Different
The American cover letter and the British one share a skeleton, but the details diverge. UK employers expect a more formal, understated tone. Where an American letter might open with an enthusiastic pitch, a British letter opens with measured clarity. Confidence is good; hype is not. Phrases like "rockstar" or "crushed my targets" that are normal in US applications read as alien — even off-putting — to many UK hiring managers.
The structure is also more standardised. UK recruitment has settled on a predictable letter shape over decades, and deviating from it signals unfamiliarity rather than creativity. Creative industries allow some flexibility, but even there, the basics — header, date, formal salutation, three to four tight paragraphs, formal sign-off — remain expected.
The Standard UK Cover Letter Format
Here is the layout UK recruiters expect, top to bottom.
Your Contact Details
Place your full name, address, phone number, and email at the top. In 2026, a full street address is optional — city and postcode are fine — but the phone number and a professional email address are not. Your email should be your name, not a nickname from 2012.
Date and Recipient Details
The date goes below your details, written in the UK format: 19 October 2026, not October 19, 2026. Then the recipient's name, job title, company name, and address. Always try to find a named recipient — a company's website, LinkedIn, or a quick phone call to reception will usually surface one.
The Salutation
Use "Dear Mr Smith" or "Dear Ms Patel" — title plus surname. Never use first names unless you know the person well. If no name is available, "Dear Hiring Manager" is the modern default; "Dear Sir or Madam" is a fading but still acceptable fallback.
The Opening Paragraph
State the role you are applying for, where you saw it advertised, and one strong reason you are a good fit — in two or three sentences. This is not the place for your life story. Recruiters decide in the first few lines whether to keep reading.
The Middle Paragraphs
One or two paragraphs connecting your experience to the job requirements. Do not repeat your CV. Instead, pick two or three achievements that map directly onto what the job description asks for, and quantify them where you can. "Increased newsletter open rates from 18% to 34% in six months" beats "strong marketing skills" every time.
The Closing Paragraph
Reaffirm your interest, mention any practical details (notice period, right to work in the UK, availability for interview), and thank the reader. Then the formal sign-off: "Yours sincerely" when you have used the recipient's name, "Yours faithfully" when you have not. Yes, this convention still matters in the UK.
How Long Should a UK Cover Letter Be?
One page. This is non-negotiable in the UK context. Aim for 250 to 350 words across three to four paragraphs. Recruiters routinely spend under a minute on an initial screen, and a letter that spills onto a second page suggests you cannot prioritise information — which is itself a data point about your communication skills.
If you are struggling to fit, cut examples rather than structure. One strong, specific achievement beats three vague ones. The letter's job is to make the reader want to read your CV, not to replace it.
British English Spelling and Tone
This is where international applicants most often stumble. A UK cover letter must use British spelling throughout: organised, emphasise, behaviour, centre, programme (for a course of activity; program is for software). Mixing spellings within a single letter is worse than getting them all wrong in one direction — it looks careless.
Beyond spelling, watch your vocabulary. Avoid Americanisms that have not crossed the Atlantic: "gotten" should be "got", "cell phone" should be "mobile", "resume" should be "CV" (and you should be writing a CV, not a resume, for UK applications). Phrases like "I am writing to inquire about" are fine; "reach out to you" is creeping in but still reads as imported corporate-speak to traditional recruiters.
Tone should be formal but human. Avoid contractions? Not strictly — "I'm" and "don't" are acceptable in most sectors now — but do not let the letter drift into chatty territory. And never, ever use humour in a cold application unless you work in comedy writing.
Tailoring Your Cover Letter to the Job Description
A template letter with the company name swapped in is detectable within seconds, and UK recruiters consistently rank it among the top reasons for rejection. Tailoring does not mean rewriting from scratch every time — it means three deliberate changes:
First, mirror the job description's language. If it asks for "stakeholder management", use that phrase rather than "dealing with clients". Recruiters — and applicant tracking systems — match keywords.
Second, lead with the requirement that matters most to them, not the achievement you are proudest of. Read the posting as a prioritised list: the first two or three requirements are the real job; everything after is nice-to-have.
Third, show you understand the company. One sentence about why this organisation — not just this role — interests you separates your letter from the fifty others on the pile. Reference something specific: a recent project, a value they actually demonstrate, a market position you find interesting.
Common Mistakes That Get UK Applications Binned
Recruiters see the same errors repeatedly. Avoid these:
Repeating your CV. The letter is a trailer, not the film. If a paragraph could be copy-pasted from your CV, cut it and write something only the letter can say.
Apologising for yourself. Never write "although I don't have much experience..." or "I know I'm not the typical candidate". You are arguing against yourself in a document whose entire purpose is to argue for you.
Generic flattery. "I have always admired your company" means nothing. "Your team's work on the NHS app rollout is the reason I want this role" means something.
Typos and name errors. A misspelled company name or the wrong recruiter name is an instant rejection for many UK employers. Proofread twice, and have someone else read it once.
Overlong openings. Starting with "My name is X and I am writing to apply for..." wastes your best real estate. Open with the role and your strongest hook instead.
A Practical Workflow
If you want to write a strong letter without starting from a blank page, tools can help with structure — a cover letter generator can produce a first draft from your details in minutes. But treat it as scaffolding, not a finished product. UK recruiters read thousands of letters; the ones that work all share one trait, and it is not polish — it is specificity. A slightly rough letter that is clearly about this job beats a flawless letter that could be about any job.
Read your draft aloud. If it sounds like something anyone could have written, rewrite the specific sentences until it sounds like only you could have written them. That is the whole game.
Frequently Asked Questions
How long should a UK cover letter be?
One page — roughly 250 to 350 words across three to four paragraphs. UK recruiters expect brevity; anything longer suggests you cannot prioritise information. If you cannot say it in a page, you are saying too much.
Do I need to use British English spelling in a UK cover letter?
Yes. Use British spellings (organised, emphasise, behaviour) and avoid Americanisms like 'gotten' or 'y'all-adjacent' informality. An American-spelled letter to a UK employer signals you have not bothered to localise your application.
Should a UK cover letter be attached or in the email body?
Follow the employer's instructions. If none are given, the convention is to attach it as a PDF alongside your CV, named Your-Name-Cover-Letter.pdf. Never send it as a Word document — formatting can shift between versions.
Is 'Dear Sir or Madam' still acceptable in the UK?
Only as a last resort when no name is available and the posting gives no contact. 'Dear Hiring Manager' is better, but a named recipient ('Dear Ms Patel') is always best. Research the company's site or LinkedIn to find a name.
Can I use AI to help write my UK cover letter?
You can use AI for structure and first drafts, but the letter must sound like you and reflect the specific role. Generic AI-generated letters are easy to spot, and UK recruiters increasingly treat them as a red flag. Always rewrite heavily and add specifics only you would know.
