Plusnet may be wonderful in other respects, but my transfer to them for upgrade to VDSL hasn't started well.
12 days after my order, they have emailed to say that they have only today (T-2) despatched my router - which "should arrive in 3-5 working days". Worst case: I will have a VDSL service but without ADSL kit to put on the end of it - and so no Broadband at all - for five (calendar) days.
Of course the kit may arrive much sooner in this case - but if it doesn't, then Plusnet make it very clear that it is my problem not theirs. And even if I hit lucky, this timing is likely to mean problems for a fair proportion of new customers to whom they send the kit late and slowly.
For anyone to whom a multi-day outage (apparently caused by nothing other than lethargy by their ISP) might be difficult, then a different ISP might be a better choice.
