Having no TV licence is not a recordable offence, and therefore it will not go on anyone’s criminal record.
You cannot be sent to prison for having no TV licence.
Both of those statements are untrue @SkelingtonArgument.
From Citizens advice:
"It’s a criminal offence to watch live TV or use BBC iPlayer unless you have a valid TV licence. Without one you risk prosecution and can be issued a fine of up to £1,000, plus court costs."
"Failing to pay at this stage could result in court action using the evidence collected by the enquiry officer. The court can issue a fine of up to £1,000 which will show up if your criminal record is checked. Your TV licence must still be paid in addition to the fine."
"No, you can’t go to prison for not having a TV licence. The court can only give you a fine for this. But if you don’t pay, the court can take further action to collect the fine, including sending you to prison as a last resort."
Spreading untruths isn't helpful to anyone.
