Contacts and channels

Writing to a public authority

What differs from writing to a company, and what to keep either way.

Updated on 13/08/2026

Writing to a public body differs fundamentally from writing to a company: there is usually a mandatory formal channel, and using another does not count. The email you sent the case officer may have served to talk, but not to submit.

The two channels, and what each is for

ChannelWhat it is forWhat remains
Formal (registry, portal, platform)Submitting, responding, meeting a deadlineA receipt with date and number
Informal (email, phone)Clarifying, asking, speeding things upWhatever you keep

Important

The formal receipt is the important document, more than what was submitted. It is the only thing proving it arrived and when, and it is exactly what belongs in the file next to what you sent.

What to keep from each procedure

  1. 1

    What was submitted, exactly as submitted

    Not the working draft: the exact file that went.

  2. 2

    The receipt, with its number and date

    It is what will be asked for if the deadline is disputed.

  3. 3

    Their reply, in the same file

    Including requests for further information, which usually run short.

  4. 4

    And relevant informal conversations

    A line with the date and what was said; not formal evidence, but it orients.

Watch out

The costliest failure is a notification landing in a mailbox nobody watches. Deadlines run regardless, and many are ten days. Notifications should reach somewhere with an owner, not a generic address created years ago.

When several procedures run at once

That last point prevents silence: when a third party handles a procedure, both sides easily assume the other is responding.

Worth knowing

If your advisers file on your behalf, ask for the receipt and keep it yourselves. It is not distrust: the deadline is yours, and so is the consequence of not being able to prove it.

Is email valid for submitting?

Unless the body expressly accepts it, no.

What if their system fails?

Keep dated evidence of the attempt; it is usually provided for.

Should submissions be sealed?

The receipt gives the date; sealing the sent file adds proof of content.
