Rights in regards to video recording of my private dwelling interior.

Hello everyone, i'm not entirely sure how to word this but i'll do my best with the information and knowledge I have.

Here's what went down, I live in a rented apartment, nothing spectacular there, and a while ago the apartment below mine was having issues with leaks. The building management company contacted my landlord who contacted me to organise a date and time to let them, building management, into the apartment to inspect and see if they could figure out the cause. Of course I had no issue with this and agreed to their requested date and time.

Few things to note here, as far as I could figure out this was not an official inspection of the apartment as per the landlords rights, this was entirely just a professional inspection of a possible source of the leak by the building management company. Anyway, they came and left fairly sure of the cause and asked if I could let a plumber in some time during the week to take care of it, of course I had no issue with that again.

Now, here's the issue, a few months later there was another leak and they needed access again, this time the landlord came along. They did their thing, and before leaving my landlord pointed at a pile of old boxes that I had and asked me if I could get rid of them, they could be considered a fire hazard. I apologized about them and said no problem, that weekend I took care of it and got rid of the boxes.

Here's where the final and actual problem came to light. They did find out the cause of the leak and told my landlord it was his responsibility to take care of it and pay for it, but he was basically ignoring them, as he does. Nice guy but pretty useless at getting anything done. Anyway, my landlord then some time later forwarded on an e-mail to me that they sent to him, listing all the issues and loaded with legal threats etc etc, he didn't seem to care but apparently if he didn't get a plumber in to deal with it then they'd have to and they'd send him the bill, or a summons, or whatever. This is where I got concerned, at the very end of the e-mail was a note about the boxes "as per the videos we sent you after the first time we went into the apartment" and that they "still weren't cleared up"! Now obviously at this point they'd since been cleared up, but I didn't know that this was the building managements request, so I only let my landlord know that it was taken care of. Anyhow I responded to the e-mail myself and said, to the management company not my landlord, that if they wanna send a plumber in I won't stop them, just let me know when and what time.

So, it turns out the very first time the building manager (only there to find the leak, not as an official inspection of the apartment as an agent of my landlord, which must be legally requested via a letter etc etc) took a sneaky video of the interior of my apartment, the boxes specifically, and sent that to my landlord with a request to get me to dump them. He didn't ask me to do that of course, not until a few months later when he himself saw them while actually in my apartment and he asked me in person.

My issue here is what "legally" is the situation revolving around the building manager (not an agent of my landlord mind you) and his secretly video recording the interior of my home. Granted I let him into the place, but under the pretense of checking for the cause of a leak, in a professional capacity! Do I have a leg to stand on to at the very least get him to delete all copies of the video (apparently he sent them to the managements solicitors before the "warning" email as part of his threat to my landlord, so they seemingly have a copy too), and if what he did /was/ illegal and he needs to delete the videos, is it in my rights to demand that I get it in writing from him and his solicitors that t he videos have been deleted.

Now before anyone asks I do not have anything to hide, there's nothing he could have gotten on the videos that i'd want deleted to protect myself from one thing or another, i'm purely curious about this entirely because of the principal of it, I strongly feel like my right to privacy has been greatly infringed upon and frankly I don't think he should get away with that. I'm not looking to sue him or run him through a grinder, I literally just want the videos deleted and his/their word that they deleted said videos, so that he's aware that he has no right to do that again to other people in the future!

As for what proof I have that he took those videos it's the e-mail he sent to my landlord, his own e-mail that he wrote himself, admitting to having taken the recordings. So any and all information by someone with the knowledge on the subject would be greatly appreciated. Thank you!

nb. Thankfully I am moving out of this place soon so I won't have to deal with the building manager again in the future, for many other reasons irrelevant to this specific situation he is just not a pleasant person.
