In reply to a post by georgelnx:

Also Plusnet is just a brand name of BT, (their words from the plc yearly reports to shareholders).

Well, yes, I would consider it more of a subsidiary. certainly in the way it operates.

It has it's own sales and customer support operations, it's pricing is different , and the products it offerd are a bit different.

And, FWIW, I've been with them since Jan 14 and it has been fine.

So to the OP - I'm curious
how does the UK differ compared to Germany in this respect of ISP providers?
