All of the cases that I have seen have been group chats. The Act in question is - https://en.wikipedia.org/wiki/Communications_Act_2003#Malici... - and there is also a 2001 Act that I believe is used when the prosecutors want a custodial sentence. The application of this law to WhatsApp has been controversial.

It is also worth understanding that in the UK, the security services use specific events to push politicians (with the help of the media) into passing these laws. The Online Safety Act is a recent example, the media campaign was orchestrated by the media/police/security services, and there was a similar campaign behind the 2003 Act...every time. To imply that the laws are there to do anything other than reduce freedom is the wrong starting point.
