Should I include a cover letter if the job advert says it's optional?

Yes, in most cases. Many hiring managers who mark cover letters as optional do still read the ones they receive. Submitting a strong, tailored letter when others do not is a straightforward way to differentiate your application without additional effort.

What is the correct sign-off for a UK cover letter?

Use 'Yours sincerely' when you have addressed the letter to a named person (e.g. 'Dear Sarah Jones'), and 'Yours faithfully' when you have used a generic salutation (e.g. 'Dear Hiring Manager' or 'Dear Sir/Madam'). This is standard UK business letter convention.

How do I write a cover letter for a UK job if I have no experience in that sector?

Be direct about the transition rather than hoping it goes unnoticed. In your opening paragraph, acknowledge you are moving from a different sector and name the specific transferable experience that makes you credible for this role. Employers respect honesty and a clear rationale far more than a letter that tries to disguise an obvious gap.

Can I use AI to write my UK cover letter?

AI can produce a useful first draft, but you should treat the output as a starting point rather than a finished letter. The most common problem with AI-generated cover letters is that they lack specific company knowledge and personal voice. Review every word, add genuine specifics about the company and role, and make sure the letter reads as yours — because your reputation with that employer is yours to protect.

How to Write a Cover Letter in the UK (2026): What Actually Works

Updated 16 June 2026

A strong UK cover letter runs to three focused paragraphs: why this role at this company, what you specifically bring to it, and a direct close. It should be tailored to the job description, written in your own voice, and no longer than one side of A4 or roughly 300–350 words. Hiring managers in the UK do read cover letters, but only when the letter earns their attention in the first two sentences. Generic openers and templated language waste that chance.

Does a Cover Letter Still Matter in the UK in 2026?

Yes, but the bar has shifted. The proliferation of AI tools means many hiring managers now receive high volumes of polished-looking but interchangeable letters. A letter that reads as clearly written for this specific company and this specific job description stands out precisely because most do not. Conversely, a generic letter is now actively worse than submitting nothing, because it signals you could not be bothered to distinguish the role from 200 others.

Tip

If the job advert says 'cover letter optional', treat it as required. Submitting one when others do not is a low-effort way to differentiate yourself.

UK Cover Letter Format: What to Include

UK employers expect a professional letter format. Unlike a US-style cover letter, the UK version tends to be more restrained in tone and direct in structure. Here is the standard layout:

Your contact details at the top right (name, email, phone, LinkedIn if relevant)
The date, written in UK format: 1 January 2026
The hiring manager's name and company address on the left — use the hiring manager's name if you can find it; 'Dear Hiring Manager' is acceptable but 'Dear [Name]' is better
A subject line: 'Application for [Job Title] — [Reference Number if given]'
Three paragraphs of body content (see structure below)
A professional close: 'Yours sincerely' if you have a name, 'Yours faithfully' if you used 'Dear Sir/Madam'

Info

File format matters: submit as a PDF unless the job advert specifies otherwise. A Word document can lose formatting across different versions of Office, and a PDF looks intentional.

The Three-Paragraph Structure (With Examples)

Paragraph 1: Why This Role at This Company

Open by naming the specific role and showing you understand what the company actually does. Reference something concrete: a product, a recent project, a market position, or a stated company goal. This is where most letters fail — they open with 'I am writing to apply for…' and say nothing about the company at all. A stronger opener looks like: 'Monzo's recent push into business banking is exactly where I want to spend the next chapter of my career — having spent three years building financial products for SMEs at [Company], I understand the customer problems you are trying to solve.'

Paragraph 2: What You Specifically Bring

This paragraph does the evidential work. Pick two or three skills or achievements from your CV that map directly to the requirements listed in the job description. Be specific. 'Strong communication skills' is not evidence — 'led quarterly briefings to a board of 12 and reduced escalations by restructuring our client reporting process' is. Keep it to what is most relevant; do not summarise your entire career history.

Paragraph 3: The Close

Close briefly and without desperation. Confirm you would welcome the chance to discuss your application, note your availability if relevant (for example, if you need to give a notice period), and thank them for their time. Do not end with a grand statement about how you are 'the ideal candidate' — let the previous paragraph do that work.

Paragraph 2	2–3 specific achievements or skills tied directly to the job description requirements	4–5 sentences
Paragraph 3	Express interest in next steps; mention notice period if relevant; brief thank you	2–3 sentences
Close	'Yours sincerely, [Full Name]'	1 line

Cover Letter Tips for the UK in 2026

Mirror the job description's language. If the advert uses 'stakeholder engagement', use that phrase rather than 'working with teams'. ATS systems and hiring managers scan for alignment with the language they wrote.
Do not repeat your CV. The cover letter should add context, not repeat bullet points. If your CV says you increased sales by 40%, the cover letter should explain the situation and why the approach worked.
Research the company before you write. Check their current LinkedIn posts, recent press coverage, and Companies House filings if they are a smaller firm. One specific and accurate reference to what they are working on is worth more than three paragraphs of generic enthusiasm.
Avoid jargon and buzzwords. Terms like 'dynamic self-starter', 'results-driven professional', and 'passionate about excellence' communicate nothing. UK hiring managers have read them thousands of times.
Keep it to one page. If your letter runs past 350 words, cut rather than adjust the font. A concise letter respects the reader's time.
Proofread for UK English. Spell checkers often default to US English. 'Organise' not 'organize', 'labour' not 'labor', 'colour' not 'color'. A US spelling in a UK application is a minor but visible error.
Address any obvious gaps proactively. If you are applying to a sector you have not worked in before, or returning after a career break, one sentence of honest framing is more effective than hoping the reader will not notice.

How AI Can Help (and Where It Falls Short)

AI writing tools can produce a structurally correct cover letter quickly, but the result is often generic without significant editing. The problem is not the grammar — it is that AI-generated letters tend to lack the specific company knowledge and personal voice that make a letter convincing. Used well, AI is a useful first draft: it handles structure, format, and tone so you can focus on filling in the genuine specifics. Used badly, it produces letters that sound like every other AI-generated letter in the pile.

Tools like Legworker approach this differently. Rather than generating a one-size-fits-all letter, Legworker researches the employer before writing anything, and tailors the cover letter to both the job description and what you have told it about yourself. You review and edit the output before it goes anywhere — nothing is submitted on your behalf. That combination of AI efficiency and your own judgement is more likely to produce a letter that reads as written for a specific company, because it is.

Common UK Cover Letter Mistakes to Avoid

Opening with 'I am writing to apply for the position of…' — it wastes the most valuable sentence
Addressing the letter to 'To Whom It May Concern' when the hiring manager's name is on the advert or LinkedIn
Describing personal qualities without evidence ('I am hardworking and dedicated')
Submitting the same letter to every job with only the company name swapped out
Including a photograph or personal details like date of birth or marital status — this is not standard UK practice and can create unconscious bias issues
Making salary expectations part of the cover letter unless specifically asked — this is better handled at interview

One page, roughly 300–350 words. Hiring managers read cover letters quickly, and a concise, well-structured letter is more persuasive than a longer one that repeats information from the CV. If you find yourself exceeding 400 words, cut the weakest points rather than shrinking the font.
