LB: We lived on a houseboat in London for a couple of years. It was wonderful. When we moved aboard, the letting agent specifically advertised it as not requiring council tax, which turned out to be a lie. We informed the council that we'd left our previous property, and were promptly billed for council tax on our apartment on the boat. Of the six apartments (it was a large barge), we were the only ones paying. Anyway, we were just up river from the riverside park in Brentford, where there were a dozen or so other boats. I got to know a few of the owners, and learned that none of them paid council tax, because the council wouldn't let them. It wasn't an official marina, just a place where boats had moored over the years, and some of them had become permanent. They *wanted* to pay tax, because they wanted post and bin collections. But they couldn't. Not the same situation as Zack Polanski, of course, but I found it interesting all the same.
