> In the UK where 20% of the internet is blocked

This sounds like an extreme over-estimate. Some ISP's, mostly mobile ones, default to blocking "adult material" unless you tell them to turn that off. Some of the larger ISPs are under court order to block some specific other content (Pirate Bay in particular; my old ISP was one of them, my current ISP happily lets me access it, not that I've ever done so other than to see if it's blocked).

Most ISPs block at most a tiny set of sites and personally in 23 years of using UK ISPs I've never "organically" run into those blocks (as in, no site I actually had any interest in accessing has been blocked; I've only seen them when checking whether people were right that a specific site was blocked). And yes, that includes visiting sites with "adult material" without running into any blocks.

I do have a VPN, so it'd take me as long to bypass as it takes me to press one button in my browser address bar, but I only need that to evade IP region/country blocks - never needed it to get around UK filtering.
