How to Write a Civil Service Expression of Interest Email
An expression of interest email is a short message to a hiring manager or named contact saying you want a particular role and would welcome a conversation. It is not an application, and it is not marked against the person specification. Its job is to give the reader a quick, clear reason to take you seriously. This guide explains when one is asked for, how it differs from a personal statement, and how to open, show your fit, handle declarations, close, and avoid the mistakes that make these emails easy to ignore.
When is one requested, and how is it different from a personal statement?
It varies by department and by campaign. Some adverts invite you to email a named contact before you apply, some ask for an expression of interest as part of the application, and others ask only for a CV and a personal statement. Read the advert and the candidate pack for the exact instruction, and follow it. If the advert names a contact for informal enquiries, that is usually the right person to write to. If the advert does not ask for one, you can still write one, but it does not replace the application or its closing date.
A personal statement is scored. A panel marks your evidence against the advertised criteria, usually with a strict word limit, and it needs to cover each essential criterion. An expression of interest is read by a person deciding whether you look relevant and capable. It should not try to prove every criterion.
Its purpose is to signal genuine interest, make a brief case, and ask for an informal conversation. Aim for roughly 150 to 200 words.
How should you open, and how do you show fit?
Open with who you are, why you are writing and how you found the vacancy. Put the job title and reference number in the subject line and again in the first sentence, so the email can be matched to the right post without anyone searching for it.
Then give one or two real pieces of evidence that match the role's purpose and main responsibilities. Choose achievements, not duties, and say what changed because of what you did. Do not paste CV bullets word for word. Rewrite them as natural sentences in the first person.
As an illustration only, you might say you redesigned a casework triage process so that average waiting times fell from six weeks to four. Use something you actually did, with figures you could defend at interview.
Show your level through the scale of what you describe, such as who was affected, how complex it was and what you decided yourself, not through bigger adjectives. Strengths are not named in adverts, so there is nothing to echo on that front. If one of the behaviours listed in the advert is naturally supported by your example, you can touch on it, but do not force it in.
How do you handle relocation, security clearance and other declarations?
Keep them to a single plain sentence, and only include them where they are relevant and true. If the role is in a different city, you can say you are happy to work from that office or are planning to relocate. If the role needs security clearance, you can say whether you already hold a level of clearance, or that you are willing to go through vetting.
Do not explain, apologise or negotiate. Conversations about working patterns, adjustments or start dates belong in the call, or later. Never state that you hold a clearance or a qualification that you do not.
How should you close, and what mistakes should you avoid?
Close by inviting a short call or conversation and giving a sense of when you are available. Include a phone number if you are comfortable sharing it. Thank the reader once and sign off with Kind regards. Keep the tone professional and warm.
Mistakes to avoid are listed below.
- Writing a long email that tries to cover every essential criterion.
- Leaving out the job title or reference number.
- Copying CV bullets or the advert wording word for word.
- Opening with generic enthusiasm instead of a specific reason for writing.
- Exaggerating, estimating figures you cannot support, or claiming experience you do not have.
- Asking for a decision, a salary or an offer, rather than a conversation.

Frequently asked questions
Does an expression of interest replace the application?›
Not unless the advert says so. In most cases it is an addition to the formal application, or an early step before it. Check the instructions for the vacancy, and submit the application before the closing date either way.
How long should an expression of interest email be?›
Aim for about 150 to 200 words. That is enough for a short opening, one or two pieces of evidence and a request for a call. Anything much longer starts to read like a personal statement.
Should I attach my CV?›
Check the advert first, because some contacts ask for one and others do not. If you do attach it, make sure the achievements in your email match it. The email should still stand on its own and not rely on the attachment.
