Most people spend hours perfecting their CV and then dash off a cover letter in ten minutes. It shows — and recruiters notice. The good news is that the mistakes most candidates make are completely avoidable once you know what to look for.
In the UK job market, a cover letter is often your first chance to make an impression. Yet most candidates make the same avoidable mistakes that immediately put recruiters off. Here are the top 10 to watch out for.1. Using a Generic Template
Sending the same cover letter to every employer is one of the biggest mistakes you can make. Recruiters can spot a generic letter instantly. Always tailor your letter to the specific role and company.
2. Starting With "I Am Writing to Apply For..."
This opener is overused and wastes your first sentence. Start with something that grabs attention — a key achievement, a bold statement about your passion for the industry, or a specific reason you want to work for that company.
3. Repeating Your CV Word for Word
Your cover letter should complement your CV, not duplicate it. Use it to tell the story behind your experience — why you made certain choices, what you learned, and why it makes you right for this role.
4. Making It Too Long
A UK cover letter should be no longer than one A4 page — ideally 3–4 short paragraphs. Recruiters are busy. Get to the point quickly and make every sentence count.
5. Focusing on What You Want, Not What You Offer
Employers don't want to read about what the job will do for your career. They want to know what you'll do for them. Flip your perspective: lead with value, not desire.
6. Spelling and Grammar Errors
A single typo can get your application binned. Always proofread carefully, use spell check, and ideally ask someone else to read it before you send.
7. Not Addressing It to the Right Person
"Dear Sir/Madam" or "To Whom It May Concern" feels impersonal. Do your research — check LinkedIn or the company website to find the hiring manager's name.
8. Being Too Modest or Too Arrogant
Strike the right balance. Don't undersell yourself with phrases like "I think I might be suitable". But equally, avoid coming across as overconfident. Be direct and evidence-based.
9. Ignoring the Job Description
The job description tells you exactly what the employer wants. Mirror their language, address their requirements directly, and show you've read it carefully.
10. Forgetting a Strong Closing
End with a clear call to action. Something like: "I would welcome the opportunity to discuss my application further and am available for interview at your convenience."
