Here is the uncomfortable truth from the hiring side: most cover letters are not read. They are opened, the first line is glanced at, and if it says “I am writing to apply for the position of…” the reader goes straight to the CV. That is not a reason to skip the cover letter. It is a reason to write one that gets past the first line. This guide shows you how, with a structure that takes twenty minutes per application and three full examples.

What a cover letter is for

The CV says what you have done. The cover letter says why it matters to this employer, for this job, now. It does three things the CV cannot: it makes the connection between your experience and their problem explicit, it explains anything the CV cannot (a career change, a gap, a relocation, why you want a step down), and it shows you can write a clear page of prose, which for most professional roles is a skill the job needs.

What it is not for: repeating the CV in sentences, telling the employer about yourself in general, or flattering the company. Hiring managers notice all three and read none of them.

The four-paragraph structure

One page. Three hundred words or fewer. Four paragraphs, each with one job.

1. Why this job. Two or three sentences. Name the role, say what about it, specifically, made you apply. Not “I was excited to see your advert”: something in the advert or about the business that a person who had not read it could not have written.
2. Why you. Your single strongest, most relevant achievement, with a number, and one sentence on how it maps to what they need. This is the paragraph that gets read.
3. Anything the CV cannot say. The career change, the gap, the move, the reason you are applying below your last level. Said plainly, in two sentences, it disappears as an issue. Left for the reader to wonder about, it becomes one.
4. Close. One line. What you would like to happen next, and thanks. No “I look forward to discussing how my skills align with your needs”.

If paragraph three has nothing to say, leave it out. Three paragraphs is fine.

The first line

The first line decides whether the rest is read. The ones that fail all start the same way: “I am writing to apply for”, “I wish to express my interest in”, “Please find attached my CV for”. The reader knows what the letter is. Start with the reason you are worth reading.

Weak: I am writing to apply for the position of Operations Manager as advertised on your website.

Strong: Your advert says the Bristol depot is moving from one shift to two in the spring. I ran exactly that change at Parcelforce Exeter in 2024, and it is the main reason I am applying.

Strong, for a career changer: I have spent eight years teaching teenagers to understand things they did not want to understand. That is most of what a customer success role is, and I would like to do it for your product.

Who to address it to

A name, if you can find one. The advert, LinkedIn, or a two-minute search of the company usually gives you the hiring manager or the head of the function. “Dear Ms Okafor” is read differently from “Dear Sir or Madam”, because it shows you did the work. If you cannot find a name, “Dear Hiring Manager” is fine. “To whom it may concern” is not; it signals a letter sent to many.

Tone

Write as you would speak to the hiring manager if you met them in the lift and had thirty seconds. Plain words, short sentences, first person, no corporate filler. The words to cut: “passionate”, “dynamic”, “leverage”, “synergy”, “skill set”, “align”, “utilise”. Each one marks the letter as assembled rather than written.

Confident, not grand. “I am confident I would be an asset to your organisation” is empty. “I have done this twice and I know where it goes wrong” is confident.

Three cover letter examples

1. Mid-career manager, same sector

Dear Ms Patel,

Your advert for a Regional Sales Manager mentions that the Midlands territory has been without a manager for six months and needs rebuilding rather than maintaining. That is the part of the job I am best at, and the reason I am applying.

At Harland Industrial I took over a region of nine that was 22% behind target and finished the year 6% over it, mainly by moving the team from reactive quoting to planned account development and cutting the number of accounts each person carried. Two of the nine were promoted in the following year. I would expect to run the same playbook in the Midlands, starting with the top twenty accounts by lapsed revenue.

I would welcome a conversation about what rebuilding the region would look like in the first ninety days. Thank you for considering the application.

2. Career change

Dear Mr Chen,

I have spent eight years as a secondary school science teacher, the last three as head of department, and in 2025 I retrained as a software developer. I am applying for the Junior Developer role because your advert asks for someone who can work with non-technical colleagues, and that is the thing I have done every day for eight years.

Since finishing the bootcamp I have built and shipped two production web applications. One is a timetabling tool now used by three schools, which replaced a process that took a deputy head a full week each term. I built it in Python and React, deployed it myself, and have handled every support request since launch. The code is on GitHub at the link on my CV.

I know this is a step into a junior role. I am applying to it deliberately: I want to learn to build software properly, inside a team, and I would rather do that at a company whose product I understand than anywhere else.

I would be glad to walk through the timetabling project in an interview. Thank you.

3. Senior, speculative

Dear Ms Lindqvist,

I read in your interim results that Marlow Foods intends to be in two further national grocers by the end of next year. I led that exact move at Fenwick & Hale between 2022 and 2025, and I am writing to ask whether you are planning to add commercial leadership to do it.

At Fenwick & Hale, a £120m private-equity-backed food business, I took the company from a single-channel to a multi-channel model, winning listings in two of the big four that added £31m of revenue ahead of the exit. The work was less about the pitch than about getting a single-channel supply chain and a single-channel sales team ready for the demands of grocery, which is where most of these moves fail.

If there is a conversation to be had, I would value twenty minutes of your time, with no expectation beyond that. My CV is attached.

Mistakes that get a cover letter skipped

• Opening with “I am writing to apply”. The reader stops there.
• Repeating the CV. If a sentence is already on the CV, cut it.
• Length. Over a page, or over about 300 words, and it will not be read.
• Flattery. “Your company is an industry leader with an outstanding reputation” says nothing and the reader knows it.
• The wrong company name. It happens more than you would think, and it ends the application.
• Explaining the gap in paragraph one. Lead with the strongest thing. Context goes in paragraph three.
• Attaching it as the first page of the CV file. Separate document, or in the body of the email if applying by email.

When you do not need a cover letter

When the application form does not have a field for one and does not ask, or when you are applying through an agency that will present you with its own summary. In every other case, send one. The people who skip it when it is optional are competing against the people who did not.

Frequently asked questions

How long should a cover letter be in the UK?

One page, under 300 words, three or four short paragraphs. If applying by email, the letter is the body of the email and can be shorter still.

Should the cover letter be a PDF or in the email?

If applying by email, put the letter in the body and attach the CV as a PDF. If applying through a form with an upload field, a one-page PDF. Never combine letter and CV into one file.

Is a cover letter the same as a CV letter?

Yes. “CV letter”, “covering letter”, “cover letter” and “letter of application” all mean the one-page letter sent with a CV.

Do employers actually read cover letters?

They read the first line, and if it earns it, the rest. For roles involving writing or client contact, many hiring managers weight the letter heavily because it is the only writing sample they have.
