When I rented a flat nearly 10 years ago, we had to get a wireless broadband solution as the local area hadn’t got any decent broadband installed yet (despite being a brand new village between two towns), however to install it they needed to drill through the entire wall. To do that I needed the landlords permission, but it turns out it was owned by someone (or an entity) in China and the estate agent couldn’t get ahold of them, so I said fuck it and just said yes they can go ahead and do it.
