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

Want to make an excellent first impression on your UK employers with your cover letter?

Here are three handy tips and tricks to keep in mind when creating yours:

  • Take the time to research: Invest in learning about the company and role by exploring their website, social media, and doing a thorough Google search. Focus on the products and services they offer, as well as awards and industry recognitions.
  • Focus on the company's values: Refer back to your research and to uncover what the company believes in. Integrate those values into your cover letter by explaining how you embody them. For example, if they value diligence, highlight how you’ve consistently met tight deadlines or successfully managed heavy workloads.
  • Align your skills with the job requirements: Read the job advert carefully and identify the most sought-after skills. Select the top three skills that you can substantiate with your most noteworthy achievements, to demonstrate your expertise in those areas.

How to format a chemical engineer cover letter

Before diving into the content, the structure of your cover letter should include the following elements:

  • Your address and contact details
  • The employer’s name and address
  • Date
  • Salutation or greeting
  • Opening or introductory paragraph
  • Middle or body paragraphs
  • Closing paragraph
  • Sign-off and signature

When it comes to the best font choice, consider modern options like Lato, Rubik, Raleway, Volkhov, Chivo, or Bitter as alternatives to Arial or Times New Roman.

Your cover letter should be single-spaced, with approximately 1-inch (2.5 cm) margins all around (our templates are set up automatically with this spacing in mind).

Ensure your CV and cover letter use the same font for consistency, and always send them as a PDF to prevent edits and maintian formatting.

Lastly, while Applicant Tracking Systems (ATS—the software used to match your application to set requirements) won't read your cover letter, recruiters certainly will, so make sure it stands out.

How to write your chemical engineer cover letter salutation

Now it's time to make it personal—in your cover letter greeting, you should always address the hiring manager directly. Whenever possible, use their name, depending on how well you know them (e.g., 'Dear Mr Smith', 'Dear Abbie').

You can find their name by searching on LinkedIn (start by looking for the job posting and the recruiter), visiting the 'About' page of the company's website, or by calling reception or administration to enquire.
