When you write a cover letter, you have an opportunity to explain the connection between your experience and one particular vacancy. Your CV records the main evidence. The letter can draw attention to the most useful parts, explain your interest and add context that would otherwise be difficult to see.
If the letter simply repeats each job in order, it adds little. If it makes sweeping claims that the CV cannot support, it creates a different problem. Aim for a short, coherent explanation of why the work interests you and how your background equips you to contribute.
Check the application instructions first
Confirm what the employer actually requests: a separate letter, a cover email, a supporting statement or answers within an application form. Follow the stated format and any word or page limit. A supporting statement organised around several criteria may need a different structure from a short covering letter.
Check the job title, reference number, recipient and deadline. Where a named contact is provided, use the correct spelling and title. If the employer accepts applications through a portal, look at the relevant fields before preparing a document that the system may not allow you to attach.
The National Careers Service cover letter guidance offers a useful starting point on introductions, relevant evidence and checking the finished letter. Apply that advice within the instructions for the vacancy you are answering.
Write a cover letter around the employer’s priorities
Identify the work that appears central to the role. Read beyond the headline job title and select a few requirements that you can support with real examples. These will become the main points of your letter.
For example, a customer success vacancy might emphasise onboarding, customer engagement and coordinating responses to problems. If your experience strongly supports two of those areas, choose examples that explain them clearly. Avoid using the space to list every application you have encountered or every responsibility you have ever held.
Make the relevance explicit. The reader should not have to work out why a particular project or previous role matters. A brief sentence connecting your example to the advertised responsibility can be more useful than adding another paragraph of general enthusiasm.
Give each paragraph a clear job
A manageable structure is an opening, one or two evidence paragraphs, a short explanation of your interest and a closing. You can combine these elements when the letter needs to be particularly brief. Keep each paragraph centred on one point.
- Opening: identify the role and introduce your relevant background.
- Evidence: explain a contribution that connects with an important requirement.
- Interest: describe what attracts you to this work or organisation.
- Closing: finish courteously and make the next step straightforward.
This structure is a guide for organising your thoughts, not wording to reproduce mechanically. A graduate applicant, an experienced specialist and a career changer will have different evidence to emphasise.
Use examples that explain more than the CV bullet
Suppose a CV says you coordinated a revised customer handover process. The letter could briefly explain what problem prompted the change, your role in agreeing the new approach and why that experience is relevant to the vacancy. You do not need to copy the original bullet and then repeat the same information in longer sentences.
Choose detail that gives the employer a clearer picture of your judgement or contribution. If the example involved a team, distinguish your actions from the wider result. Use figures only when they are reliable, meaningful and suitable to share.
An illustrative sentence might be: “In my recent support role, I coordinated follow-up actions between customers and the technical team, keeping customers informed while outstanding issues were investigated.” It becomes useful only when it accurately describes your experience and relates to the role you are targeting.
Make your motivation specific and believable
Research the organisation using its own website and the material supplied with the vacancy. Look for something that genuinely affects your interest: the customers served, the type of product, the focus of the team or the responsibilities of the position.
You do not need to praise an organisation as the best in its sector. Explain the work that interests you and why it connects with your experience or direction. Check every company-specific statement before including it, especially if you are adapting an older draft.
If you are changing careers, explain the move positively and briefly. Focus on the connection you have identified and the preparation you have undertaken. A long account of dissatisfaction with your current job can distract from the reasons an employer should consider your application.
Address context selectively
A letter can help explain a transition, recent relevant learning or experience that is not obvious from job titles. Use this space where the explanation supports the application. You do not need to describe every personal circumstance or justify every past decision.
Where you are still developing a skill, describe your current level accurately. Completed training, practice projects and professional experience are different forms of evidence. Do not use the letter to claim expertise that the CV and interview cannot substantiate.
If you are unsure which evidence deserves emphasis, use the Free Role Gap Score at MyJobFixer.com to review the fit between your CV and target role. Check the feedback before using it to write a cover letter, particularly where it suggests that information is missing.
Finish with a consistency check
Read the CV and letter together. Do the job titles, dates, qualifications and examples agree? Have you named the correct employer throughout? Is every paragraph doing useful work? Remove repeated claims and wording that sounds unlike you.
If you use AI to write a cover letter, give it verified facts and review every sentence. Reject invented achievements, unsupported company claims and exaggerated descriptions of your level. Save the final version alongside the vacancy and CV you submitted, so you can prepare for questions about exactly what the employer has read.
