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

You only have one chance to impress your potential UK employers, so be wise about writing your cover letter.

When doing so, follow these three simple but essential steps:

  • Do your research: Begin by researching the company and the role you're applying for. Check their website, social media pages, and relevant news to understand what drives their business.
  • Highlight company values: Identify the company's core beliefs and explain how your personal and professional experiences resonate with them. For instance, if the organisation prioritises innovation, provide examples where you've demonstrated creative thinking.
  • Match your skills to the job: Analyse the job description carefully and pick out the most important skills or qualifications they’re seeking. Be sure to mention your relevant achievements that prove you're the perfect fit for the position.

How to format a office assistant 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 office assistant 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.

How to write your office assistant 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 office assistant cover letter body

Your cover letter body is the most spacious and vital part of this document—it highlights your true value and the impact you can bring as a candidate.

Remember, your cover letter serves a different purpose to your CV. Here, you need to show your skills in context by telling the story of one significant achievement, hinting at how you’ll help your future employer achieve their goals.

So, when writing your cover letter body:

  • Use concrete achievements to demonstrate your personality and impact.
  • Support your achievements with quantifiable data and metrics.
  • Tell the story of a successful project you’ve worked on and explain how you contributed to the outcome.
  • Highlight both hard and soft skills to make your story more engaging.

How to write a closing paragraph

When ending your cover letter, you have two options:

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.
