Importance of cover letters in the United Kingdom

Cover letters provide recruiters with the opportunity to learn more about your career aspirations, hinting at how you’d integrate within the organisation over the long term.

Here are three additional reasons why cover letters are important:

  • Making an excellent first impression (and a formal introduction): Your cover letter is often the employer’s first introduction to you, showcasing your personality, communication skills, and motivation for the role.
  • Complementing your career history: While your CV lists qualifications and experience, a cover letter provides the context, explaining how your background fits the role.
  • Demonstrates your genuine interest: A well-crafted cover letter reflects the effort you’ve put into researching the company and role as well as your attention to detail.

What UK employers expect from a cover letter

When writing your cover letter for a UK employer, it’s important to keep several things in mind. First, you need to conduct a thorough research, which includes reading up on the company’s website, recent news, and their presence on social media. Understanding the company’s latest achievements and its overall mission will allow you to tailor your letter to their specific needs.

Next, focus on the company’s core values. Whether they value teamwork, innovation, or community involvement, highlighting how your own experience aligns with these principles is essential.

Finally, don’t forget to match your skills to the job’s requirements. Study the job description carefully and pick out the most important qualifications or competencies. Then, provide evidence of how you meet those criteria with concrete examples from your past work experience.

How to format a system administrator cover letter

Have you ever wondered about the formatting and structure of your cover letter?

Read on to discover some guidance from industry-leading professionals:

  • Within the header, include your address and contact details, the employer's name and address, and the date, followed up by a personalised salutation.
  • The body should should consist of an opening paragraph, middle paragraphs expanding on your unique experience and skills, and a closing paragraph.
  • End with a formal sign-off and your signature.
  • Choose modern fonts such as Volkhov, Chivo, or Bitter instead of the more traditional Arial or Times New Roman.
  • All of ENhancv's templates maintain single-spacing with approximately 1-inch (2.5 cm) margins on all sides to ensure a neat presentation.
  • Always send your cover letter as a PDF to keep the formatting intact and prevent any edits once submitted.

Your CV and cover letter maintain consistent formatting. Use the same fonts, margins, and style to create a professional and cohesive look for your application.

Finally, remember that Applicant Tracking Systems (the software some companies use to align job keywords to your experience, also known as ATS) do not read cover letters–it's intended solely for recruiters. Make it stand out by highlighting your achievements and relevant skills for the role.

How to write your system administrator cover letter salutation

In a world of AI and instant prompts, taking the extra time to personalise your cover letter truly makes a difference.

Address the hiring manager directly with a customised greeting (e.g., 'Dear Mr Bond', 'Dear Ms Penny').

You can often find their name on LinkedIn (under the job listing or by searching) or in the ‘About’ or ‘Meet the Team’ section of the company's website. If in doubt, you can also contact the reception for assistance.

If you can't find the name, rather than using 'Dear Sir or Madam', opt for something more personal, such as 'Dear [Company Name] Hiring Manager'.
