🇬🇧 Administrative Assistant cover letter example (UK, 2026)

A strong administrative assistant cover letter does three things in under a page: shows you read the advert, proves your claims with numbers, and sounds like a person. Here is a complete example you can adapt — replace every [bracketed placeholder] with your real details, and only claim what is true.

The example letter

Dear [Hiring Manager's name — or "Hiring Team"],

I am writing to apply for the Administrative Assistant position at [Company]. I keep offices running quietly and well — and your advert's mix of [diary management, minute taking and document control] is exactly my day-to-day.

At [Current Company], I support [three] directors and a team of [25]: managing diaries across time zones, taking board minutes, arranging travel, and processing invoices in [system]. I type at [65]wpm, live in Microsoft 365, and built a shared filing structure that cut document-hunting to seconds. Colleagues describe me as the person who has already handled it.

I would welcome the chance to discuss how I can contribute to [Organisation]. My CV is attached, and I am available for an interview at your convenience. Thank you for your time and consideration.

Kind regards,
[Your name]
[Phone] · [Email]

Before you send it: UK conventions: address it to a named person if the advert gives one, keep it to one page, and attach it as a separate document unless the application form has a dedicated box.

How to adapt this letter in 5 minutes

Replace every placeholder with specifics — a letter with one real number beats a page of adjectives.
Mirror the advert's exact vocabulary: if they say "stakeholder management", don't write "working with people". Applicant tracking systems score the letter too.
Cut anything you can't defend in an interview. Honest and specific wins.
Name the organisation twice, maximum — once at the start, once at the close. More feels like flattery.
Read it aloud once. If a sentence sounds like a robot wrote it, rewrite it in the words you'd actually say.

Questions people ask

How long should a administrative assistant cover letter be?

Three to four short paragraphs — under one page, roughly 250–350 words. Hiring managers skim: one paragraph on why this job, one with your strongest evidence, one to close. Anything longer dilutes your best material.

Should I write a new cover letter for every job?

Yes — and it matters more than people think. Recruiters and applicant tracking systems both respond to letters that mirror the specific advert's language. Adapting this template takes minutes; CVAutomate's generator does it in seconds from the actual job advert.

What should I never put in a cover letter?

Restating your entire CV, generic praise ("your prestigious company"), salary expectations unless asked, and anything untrue. Every line should either show evidence or show fit.
