Importance of cover letters in the United Kingdom

A well-crafted cover letter can significantly strengthen your job application by emphasising why you’re an ideal fit.

Here are some reasons why it matters:

  • Personalisation: Employers expect your cover letter to demonstrate how your skills and experience align with the company’s needs and/or values.
  • Addresses what is omitted from your CV: If your career path includes gaps or changes, your cover letter is the best place to address these positively and explain their relevance.
  • Opportunity to stand out: Many applicants have similar qualifications, so a tailored cover letter can show your unique attributes and experience.

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 data 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.

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 data engineer cover letter salutation

It's never advisable to begin your cover letter with 'Dear Sir/Madam', as it sounds comes across as impersonal.

Take the time to find out who is hiring for the role and address them directly in your cover letter greeting (e.g., 'Dear Mrs Chanceworth', 'Dear Harrod').

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.

How to write your data engineer cover letter intro

A great option to begin your cover letter is by showing recruiters you've done your homework or research.

If the company has won an award or made headlines, congratulate them in your opening sentence, or express how impressed you are.

Provide this achievement as a reason why you admire the company, ensuring your tone remains genuine, sincere, and authentic.

This initiative was a testament to my ability to solve complex technical challenges and drive tangible results through innovative solutions. My methodical approach and commitment to continual improvement were crucial in understanding our bottlenecks and implementing robust solutions that stood the test of time.
