Importance of cover letters in the United Kingdom

Cover letters are a crucial tool in making your application personal and engaging.

Here are three reasons why they matter:

  • Personalisation: Unlike a CV, a cover letter allows you to show your enthusiasm for the role, giving a more personal insight.
  • Addresses details about your career: Whether you’re changing careers or have gaps in employment, your cover letter offers a space to explain these in a constructive way.
  • Meeting the job requirements: Your cover letter should be unique and tailored, clearly showing how your skills align with the role requirements.

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 web developer 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 web developer 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 web developer cover letter intro

Employers do want someone who not only delivers results but does so with enthusiasm.

Thus, a great way to start your cover letter is by showing how your personal passions align with the role.

Highlight one or two aspects of the job description that resonate with you, and explain why this makes you a perfect fit for the company and its culture.

How to write your web developer cover letter body

As you reach the body of your cover letter, you might wonder what to write in it.

Our advice? Don’t just copy your CV—choose your greatest achievement and tell its story.

Focus on how you got there using hard and soft skills, describe your involvement, and quantify the results with concrete outcomes.

Remember, recruiters aren’t looking for an epic tale of your career—they want something concise, relevant, and directly addressing their needs.

How to write a closing paragraph

Now we’ve reached the closing paragraph of your cover letter. You might be tempted to end with a simple Yours sincerely, but don’t!

Instead, finish with a promise to enhance the company’s performance metrics (backed by your hard and soft skills), to develop as a professional, or something else that holds significance for the organisation. Whatever you choose, ensure to stand behind your words and be remain sincere.

Don’t forget to include a call to action, encouraging recruiters to suggest the best time to follow up for an interview or update.
