IDNet has great support but unfortunately if you end up on Zen backhaul then Zen are the weakest link.
Despite being on FTTP and IDNet advertising themselves as the lowest latency UK network, latency can double depending on which routing Zen decides to throw you around, sometimes it is the lowest latency but equally other times it is the highest latency network.
If you are someone that is likely to be using your connection between 1am and 2am regularly, then expect to get interrupted every few weeks whilst Zen throw you off to shuffle everyone around and load balance their network (I assume). IDNet give no indication of these drops, either as a pre-warning of overnight maintenance or any acknowledgment after the fact on their service status pages, and this to me is at odds of what I would expect from a business oriented ISP.
Speeds will also vary depending on which congested or uncongested route you find yourself on with Zen.
IDNet support has said that is how it is with no fix offered, and indeed that is true as Zen customers often complain of the same things.
Great support but let down by using Zen backhaul.
My advice, only consider IDNet if you get it confirmed they will connect you using anyone other than Zen, if not, you might as well just go to Zen directly and see if you can save some money.
