"Users need speeds of around 20Mbps (megabits per second) in order to watch 4K content without glitches, experts say."
What's the point of 4K with such a low bitrate. The quality is going to be shit.

Actually the quality will be the same, you just wont be able to watch it in real-time, since it will just buffer all the time.

That doesn't seem to make sense with what was stated in the article? I assume that by "glitches" they mean stuttering and maybe buffering. Why else would they say that?
Surely you can compress 4K video down to 20Mbps, but it'll just look shit.

Assuming 30fps, that'd be around ~85 kilobytes per frame (3840 x 2160 presumably)

Television in the UK is 25fps, even if the content at the source is 30fps it will be converted to 25fps for broadcast.

I'm pretty sure that isn't true any more now that all TV broadcast systems in the country are digital. PAL was limited to 25 fps but DVB has a variable frame rate depending on the source.

It is but they still use 25fps with no exceptions.

If you read the context around that sentence, its so it's compatible with current broadband specs. The average broadband speed in the UK I believe is 20-22Mbps (although probably less). No point pushing something to only those with 50Mbps because then it's a minority of people will have access to it.
4k at 20mbps can look fine, the problem is most broadcast encoding is done so lightly that even SD will look shit sometimes, alteast here in the US.
