Here’s why they’re important:

  • Indicates your genuine interest: A well-researched cover letter reflects your knowledge of the company and role.
  • Professionalism from the outset: Employers expect your cover letter to be structured, polite, and formal. If you wish to add a more personalised touch, be sure to address your recipient directly.
  • Capture the recruiters' attention: For most roles, candidates tend to have rather similar experience, which is why you should use your cover letter to explain what is unique about your profile.

What UK employers expect from a cover letter

Your UK employers will appreciate your application if you've taken the effort to tailor your cover letter to their job requirements.

Here’s how to ensure yours ticks all the right boxes:

  • Research the company thoroughly: It's not enough to have only read the job advert. Look into the company's history, products, services, and recent achievements to demonstrate your genuine interest and knowledge.
  • Connect with the company’s values: Every company has core principles that shape its culture and operations. Identify these values and use your cover letter to show how they align with your professional conduct and ethics.

How to format a devops engineer 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.

If you're uncertain where to find the hiring manager’s name, check the company website, look on LinkedIn, or send a courteous email requesting this information. Don't hesitate to ring reception either—they are unlikely to refuse to assist.
