Importance of cover letters in the United Kingdom

Cover letters are a vital part of professional job applications, helping shape recruiters' first impression of your profile.

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

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 supervisor cover letter

Your cover letter is your opportunity to make a strong impression, so its structure must be professional and clear.

Here's an overview of how a UK cover letter should be structured:

  • Begin with your address and contact details at the top.
  • Include the employer’s name and address directly below.
  • Add the date to the left or right of the page.
  • Use an appropriate greeting, such as 'Dear Mr Smith' or 'Dear Sir/Madam.'
  • Open with a strong introductory paragraph.
  • Develop your points in the middle paragraphs, focusing on relevant skills and experience.
  • Close with a concise conclusion, reiterating your interest and suitability for the role.
  • Sign off formally with your name and signature.

The software used to match your profile to the job, Applicant Tracking Systems (ATS), won’t scan your cover letter. Instead, the cover letter reads as a more personalised note to the recruiter.

When it comes to choosing a font, consider modern options like Lato, Rubik, or Chivo, which should also be applied to your CV to maintain a consistent appearance.

Additionally, your cover letter should be single-spaced with 1-inch (2.5 cm) margins on all sides (our templates are pre-set with these specifications so you can focus on your cover letter content).

Finally, always send your cover letter as a PDF to preserve the formatting and prevent edits.

How to write your supervisor 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'.

How to write your supervisor cover letter intro

One of the best ways to grab a hiring manager's attention? Show them the unique value you'd add to the team.

Review the skills or requirements listed in the posting and draw connections to your previous work experiences.

How to write your supervisor cover letter body

You’ve personalised your greeting and introduction—now it’s time to focus on writing the body of your cover letter.

Instead of listing off skills and responsibilities from your CV, focus on one career highlight that’s relevant to the role.

Use your hard and soft skills, success metrics (e.g., percentages or sales figures), and the long-term impact it had on the company.

A concise, well-told story centred on your value as a candidate will make a strong impression.

During my tenure as Operations Manager at Branch Ltd., one of the most significant achievements was the comprehensive overhaul of the department's project management framework.

This experience underscored the importance of adaptability and clear communication, skills I am eager to bring to your team as a supervisor, to drive operational excellence and further optimise project outcomes.

How to write a closing paragraph

When ending your cover letter, you have two options:

Option one is to promise how you’d contribute to the organisation—whether that’s improving a target or achieving a specific goal—or how the company could help you grow professionally. Always emphasise the tangible impact you can deliver.

The second option is to close by asking when you can expect to hear back from the hiring managers, whether for an update or to arrange an interview.

Cover Letter Closing
Thank you very much for considering my application for the Supervisor role. I am eager to bring my experience in leadership and team development to your organisation and contribute to its continued success. I would welcome the opportunity to discuss how my skills and experiences align with the goals of your team. Please feel free to contact me at your earliest convenience to schedule an interview.
