The Online Safety Act and Hate Crime Provision have extended these somewhat into the realms of 1984. But the police do tend to use them sparingly.

"insulting words or behavior that cause distress to others"
Malicious Communications Act 1988 (Section 1):

Communications Act 2003, Online Safety Act 2023, hate speech, terrorist legislation all made these many orders of magnitude worse in many ways.
