We know that. I'm fairly sure 95%+ of John Lewis customers don't at the time they sign up. Probably including the OP.
I expect Ofcom apply the same test as thinkbroadband, though I haven't checked. That is, that to be an Ofcom-listed ISP it needs a RIPE IP address allocation.
Which doesn't alter the fact that as end-user retailers they need to be registered with an ADR.
Plus, [cough], the customers are not contracted with Plusnet.
They are contracted with John Lewis, who subcontract the service supply to Plusnet. John Lewis could at any time move to a different subcontractor, taking their customers with them. Similar having happened many times. Most recently the Post Office and Tesco.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
