For some reason it’s dated 31 December 2024, however, as it only arrived this week I count it as the first (of probably many) TV Licensing letters of 2025. And it’s a bit bland and disappointing:

I don’t know, is that the best they can do to start the year? Are their creative writers all on holiday? No new scary threat?
All it does is rolling out the same old tropes we’ve already had several times. Only to tell me that they’ve opened an investigation. How does that work? You already opened one, I have plenty of letters telling me that already. How can you send me an “official notice” then telling me you’re doing an investigation, considering you’ve been doing that for the last year?
Are you that inefficient? Shouldn’t you be getting somewhere by now?
Well, let’s see what the next letter will bring, hopefully it will be a bit more exciting.
