Importance of cover letters in the United Kingdom
Cover letters provide recruiters with the opportunity to learn more about your career aspirations, hinting at how you’d integrate within the organisation over the long term.
Here are three additional reasons why cover letters are important:
- Making an excellent first impression (and a formal introduction): Your cover letter is often the employer’s first introduction to you, showcasing your personality, communication skills, and motivation for the role.
- Complementing your career history: While your CV lists qualifications and experience, a cover letter provides the context, explaining how your background fits the role.
- Demonstrates your genuine interest: A well-crafted cover letter reflects the effort you’ve put into researching the company and role as well as your attention to detail.
What UK employers expect from a cover letter
A great cover letter can set you apart when applying for jobs in the UK.
Follow these tips to ensure you make a strong impression:
- Research thoroughly: Spend time delving into the company’s website, social media, and industry news to understand their projects, awards, and future plans. The more specific your knowledge, the better you’ll be able to demonstrate your suitability for the role.
- Reflect their values: Every UK company has its own set of values that guides their culture. Once you’ve identified them, make sure your cover letter reflects how your values and work ethic align with theirs. If they’re known for integrity, emphasise your commitment to ethical practices.
- Tailor your skills: Focus on aligning your most relevant skills with the job description. Look for key terms and priorities mentioned in the advert, and make sure to provide examples of how you excel in those areas.
How to format a full stack developer 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.

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.

How to write your full stack 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.

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'.
