How to structure your cover letter
A cover letter should be concise yet informative, highlighting relevant skills and achievements with clear examples. While senior or academic roles may require more detail, UK employers generally expect a polished and focused one-page cover letter.
Key formula for an effective letter
1. Hook: A compelling opening that states your interest in the role.
2. Core: Key skills and accomplishments that align with the job requirements.
3. Closer: A strong closing paragraph summarising your suitability and enthusiasm.
1. Introduction
Address the hiring manager by name where possible (e.g., “Dear Ms Smith”).
Mention the role you’re applying for.
Briefly summarise your top qualifications.
Example
"I’m excited to apply for the Digital Marketing Specialist role at ABC Agency. With three years of experience increasing web traffic by 150% through strategic SEO campaigns, I’m eager to bring my skills to your innovative team.”

2. Main body
Break this into 2–3 short paragraphs to maintain flow.
Highlight key achievements, using numbers where possible.
Show how your experience matches the job description.
Example
“In my role as a Marketing Associate at XYZ Ltd, I managed a team to implement a social media campaign that boosted engagement by 30% in Q1 2023. I pride myself on delivering measurable results and tailoring campaigns to target audiences effectively. I’ve attached further examples of my work for review.”
3. Closing paragraph
Reiterate your enthusiasm and suitability.
Include a call to action, such as scheduling an interview.
Example
“I would welcome the opportunity to discuss how my experience in data-driven marketing could help ABC Agency achieve its 2025 growth targets. Thank you for considering my application – I look forward to hearing from you.”

Use a clear structure: Include a short introduction, a focused main section, and a professional closing.
Tailor your content: Only mention experience and skills that match the role and company.
Keep paragraphs short: Clear spacing and concise sentences improve readability.
Highlight key achievements: Use specific examples or bullet points to make important information stand out.

Common mistakes to avoid
Even the best candidates can trip up with these cover letter pitfalls:
Overloading with details: Listing your entire work history belongs on your CV – not in a brief cover letter.
Generic openings: Avoid phrases like “To whom it may concern.” It’s better to take the time to research the hiring manager’s name.
Excessive length: A cover letter over 400 words might lose the recruiter’s interest.
Ignoring the job description: Make sure your skills and experiences address the specific qualifications listed.
American spelling or format: Use UK English (“organisation” not “organization”) and follow British formatting conventions.
Using AI without editing: AI-generated cover letters that are not personalised can feel generic and are often easy for hiring managers to spot
Ignoring keywords: use relevant language from the job description to improve your chances of passing automated ATS screening systems.
Pro tip
Always have someone review your application before submitting it. A fresh pair of eyes can catch typos, awkward phrasing, or unclear points you might have missed.

FAQs
How long should a covering letter be in the UK?
The ideal length for a covering letter in the UK generally falls within one page, typically ranging from 250 to 400 words. This length allows you to provide sufficient information while maintaining conciseness and ensuring the reader's attention is captured effectively. Learn more about how long a CV should be to accompany your cover letter.
Is a two-page cover letter too long?
A two-page cover letter is generally considered too long, as it may exceed the reader's attention span and could come across as excessive. It's important to prioritise the most relevant and compelling information, focusing on key qualifications and experiences that directly align with the job requirements.
How long should an academic cover letter be?
For academic cover letters, the length may vary depending on the specific requirements outlined by the institution or position. In general, academic cover letters tend to be slightly longer than traditional cover letters, ranging from one to two pages. However, it's still essential to maintain conciseness and emphasise the most pertinent academic achievements and research experiences relevant to the role. Adhering to any specific guidelines provided by the institution or position is crucial in ensuring your cover letter is well-received.
How long is too long for a cover letter?
A cover letter is considered too long if it exceeds one page or goes beyond 400 words for most roles. UK employers typically prefer concise, focused cover letters that highlight your most relevant qualifications without unnecessary detail. Longer cover letters risk losing the reader’s attention and may come across as unfocused or overly informative. However, for senior, executive, or academic positions, a slightly longer cover letter (up to 600 words) may be acceptable if it provides detailed, relevant insights. Always aim for clarity, brevity, and relevance to make the best impression.
How many words should a cover letter be?
A cover letter should ideally be between 250 to 400 words. This length provides enough space to highlight your key qualifications, experiences, and enthusiasm for the role while remaining concise and easy to read. For senior, executive, or academic positions, you might extend it slightly, but staying within this range ensures your cover letter is impactful without overwhelming the reader. Always focus on relevance and clarity to make every word count!
Should I use AI to write my cover letter?
AI can help you draft and structure a concise cover letter, but you should always personalise it. Generic AI-generated cover letters are easy for hiring managers and ATS to spot and may reduce your chances of success. Use AI as a starting point, not a final draft, and keep your cover letter tailored to the job and around 250-400 words.
How do I write a cover letter with no experience?
Focus on transferable skills, education, volunteering, internships, or personal projects that demonstrate your suitability for the role. Highlight qualities such as communication, teamwork, organisation, and willingness to learn. Keep your cover letter tailored to the job description even if you have no experience and explain why you’re interested in the role and company. A strong, enthusiastic introduction and relevant examples can help you make a positive impression, even without formal work experience.
