This is the sort of the thing the TV licence Nazis do:

"Michael Shakespeare, from Grays, made sure all his equipment at home could not receive a live TV signal and watched catch up TV through the internet, which you do not need a TV licence for.
Mr Shakespeare wrote to the authority to inform it what he had done, inviting it to send someone round to check it out.
An inspector was sent round to check the equipment and Mr Shakespeare filmed it.
He heard nothing more until five months later, when a summons for court arrived in the post for non-payment of his TV licence.
TV Licensing obtained a copy of Mr Shakespeare’s video, which was uploaded on to YouTube, and said it showed a frozen image on a TV screen of The One Show, proving Mr Shakespeare was receiving live TV.
But Mr Shakespeare said the image was not present in his original video.
In a landmark case at Basildon Crown Court, the judge found Mr Shakespeare had no case to answer, as TV Licensing could not prove the validity of the video. Their own inspector also said in court he had not seen the frozen image when he visited."
And that's why you tell them to FUCK OFF when they come to your door. You do not politely invite them in to inspect your house so they can stitch you up like a kipper. Be as rude as possible so the message is very clear that you are not going to engage with their shit.
They also illegally prosecute people without using legally qualified staff.
