Threatening Communications Online: Section 181 and the 5-Year Maximum Sentence

Published 9 July 2026

Section 181 of the Online Safety Act 2023 carries the highest maximum sentence of any individual-speech offence short of the hatred provisions — 5 years imprisonment on indictment. It was designed for the most serious category of online threat: a threat of death or serious harm, sent with intent to cause fear — or recklessness as to whether fear results.

Disclaimer: General information, not legal advice.

The Three Elements

(1) The message conveys a threat of death or serious harm. Not general menacing — death or serious harm specifically. (2) The sender intended the recipient to fear the threat would be carried out, or was reckless as to whether they would. (3) No requirement that the recipient actually feared the threat. The offence is complete on sending.

Intent or Recklessness

The recklessness route is important. You do not need to have wanted the recipient to be terrified. It is enough that you knew there was a risk they would take the threat seriously — and you sent it anyway. The "I was only joking" defence does not work at the mental-element stage if a reasonable person would have feared the threat.

How It Differs From s.127 "Menacing"

Section 127 covers any menacing message — 6 months, awareness standard. Section 181 is narrower (death or serious harm only) but carries a dramatically higher sentence (5 years vs 6 months) and a higher mental element (intent or recklessness vs mere awareness). A message that is menacing but does not threaten death or serious harm stays under s.127.

The Chambers Principle

Chambers v DPP [2012] still applies: a message is not threatening if no reasonable person reading it in context would treat it as genuine. But the bar is higher — the threat must be of death or serious harm, and the sender must have been at least reckless as to fear.
