Is a cover letter still necessary in 2026?

From the UK recruitment desk: I read cover letters for senior roles, career-change applications, and any role where the CV alone doesn't fully answer 'why this candidate'. I skim or skip cover letters for junior roles, graduate scheme applications, and high-volume entry-level positions where the CV plus a basic application form is sufficient.

When the cover letter matters most. Stretch applications where you're missing a 'required' qualification — the letter is the place to acknowledge the gap and frame your compensating strength. Career changes — the letter is where you explain the pivot, name the evidence of commitment to the new field, and address the obvious 'why is this person from industry X applying for a role in industry Y?' question. Senior roles where 2-3 candidates are technically qualified — the letter is what differentiates them. Specialised roles where domain context matters — the letter is where you can demonstrate you understand the actual problem the role is solving.

When the cover letter is filler. Generic letters that paraphrase the CV in prose — these add nothing and hiring managers spot them immediately. Letters that lead with 'I am writing to apply for [role] at [company]' — every reader knows that already. Letters longer than half a page — they signal the candidate doesn't respect the reader's time. Letters that don't reference the specific company or role — they read as templates and they are templates.

What works. Three short paragraphs, around 280 words total. Paragraph 1: direct, names what you're applying for and one specific reason for this role at this company (not 'your inspiring mission'). Paragraph 2: translates the proof — pick 2-3 pieces of experience from your CV that map most directly onto the target role and explain the link explicitly. Paragraph 3: closes with intent — what you bring, what you'd love to discuss, and a soft ask for the next conversation.

What to skip. Apologetic openings ('I know my background isn't a perfect fit'). Long stories about why you're leaving your current role. Anything about being passionate, dynamic, or results-driven (the recruiter has read these phrases 200 times this week). Any reference to your 'journey' — particularly that word, which makes UK hiring managers flinch.

AI cover letters. Most candidates use AI to draft cover letters now. The fix isn't avoiding AI — it's editing AI output until it sounds like you. Recruiters can spot raw AI cover letters in 10 seconds. The pattern is: too smooth, too generic, no specific reference to the company, no actual personality. The candidates who use AI well treat the output as a first draft and then rewrite the opening, the specific reference, and the closing in their own voice.

Practical recommendation. For junior or high-volume roles where the application portal makes the cover letter optional, skip it and put the time into tailoring your CV instead. For senior, stretch, or career-change applications where the cover letter is the lever, write a tailored 280-word letter for each application. Twenty minutes per letter. Don't reuse the same letter across multiple roles — the small differences in framing matter.
