Worse than BT then who only throttle bittorrent.
£17.25/mo for 80Mb will do just fine for me.
Essentials is.. not the unlimited product.
On the unlimited product there's no specific throttling just "because", more priorities. The way I understand it is that if you are only using something that is at a low priority, you'll get full line speed.
As soon as something at a higher priority tries to compete, it'll win over and the torrent will slow down. E.G. VoIP would get the bandwidth it needs, while the torrent would be slowed to allow this.
The only exception to the rule would be if your fibre cabinet, or Plusnet started to experience a capacity problem. No reports so far of congested cabinets (that I've seen at least!), and Plusnet do seem to be very vocal about the constant upgrades and improvements to their network, so I'd suspect the latter shouldn't cause much of an issue.
Me? I'd be on that product like a shot if I had fibre available. As it is, with emailing Openreach they explained my cabinet wasn't even being considered. So I re-signed for 12 months (and a tidy discount) with Be*.
