How to Write a Cover Letter (UK Guide)

The cover letter is the part of a job application people most often rush, resent or skip, and it shows. A weak, generic letter adds nothing, but a sharp, tailored one can be the thing that gets your CV read properly and moves you to the top of the pile. Employers use it to see whether you understand the role, why you want it, and whether you can communicate. This guide explains how to write a cover letter that actually helps you, not one that simply repeats your CV.

It is written for UK job seekers who want a cover letter that opens doors rather than filling space.

Do You Still Need a Cover Letter?

When an employer asks for one, always include it, and make it count. Even when it is optional, a strong, tailored letter can set you apart, because so many candidates either skip it or send something generic. What has no value is a bland template addressed to no one. A letter written for the specific role, on the other hand, is a genuine advantage.

The Structure of a Strong Cover Letter

Keep it simple and follow a clear shape.

• Opening. Say which role you are applying for and open with a genuine hook: why you are a strong fit or why this role interests you, in a sentence that makes the reader want to continue.
• The middle. This is the heart of the letter. Match your experience to what the job asks for, picking two or three of your strongest, most relevant points and backing them with brief evidence.
• Why this company. Show you have done your homework and explain why you want to work for them specifically, not just any employer.
• Closing. Finish with a confident line about wanting to discuss the role, and thank them for their time.

Tailor It to the Job and the Company

The single biggest mistake is sending the same letter everywhere. Read the job description closely and mirror the language and priorities it uses. Name the company and refer to something specific about them. A tailored letter takes a few extra minutes and is worth far more than ten generic ones, because employers can tell instantly which is which.

Show, Do Not Tell

Anyone can call themselves hard-working and a great communicator. Those words prove nothing. Instead, show it with brief evidence: what you achieved, delivered or improved, ideally with a number. One concrete example is worth a paragraph of adjectives, and it is what makes a reader believe you.

Keep It Short

A cover letter should fit on a single page, usually three or four short paragraphs. The reader is busy and skimming, so every line must earn its place. If a sentence does not help your case for this job, cut it. Short, focused and specific beats long and vague every time.

Get the Tone Right

Aim for professional but human. Write in clear, natural language rather than stiff formality or empty buzzwords. Let a little genuine enthusiasm show, because employers hire people they want to work with, not just a list of skills. Read it aloud to check it sounds like a real person and not a template.

Common Cover Letter Mistakes

• Sending a generic letter that could go to any employer.
• Simply repeating your CV instead of adding to it.
• Making it too long, so the key points get lost.
• Leaving in the wrong company name from a previous application.
• Typos and careless errors, which undo all the effort.

Format and Presentation

Match the look of your cover letter to your CV so the application feels consistent and professional. Address it to a named person where you can find one, and keep the layout clean and easy to read. Save and send it in the format the employer asks for, alongside your CV.

The Bottom Line

A cover letter earns its place when it is short, tailored and specific, when it matches your experience to the job, shows genuine interest in the company, and proves your points with evidence rather than adjectives. Skip the generic template, write for the role in front of you, and your letter becomes a reason to read your CV properly rather than a box you ticked.
