This week has been really bad, there is a lot of red on the graph, even at night when laptops are off

If I find that the ethernet connected laptop is still bad is there any advice anywhere on how to deal with the provider ? It seems all they do is carry out a line check & if all looks ok then that is the end of conversation.
If the line check their end looks ok does this 100% mean there is nothing they can do ?
It's all quite a coincidence that this started happening as soon as we moved over to them.
the red shows paxcket loss.. when it reaches the bottom it means you have 100% loss, i.e. no connectivity.. this is really indicative of a problem rather than using the broadband a lot.. yellow spiking can be from use.. red would have to be very extreme, when we're talking the scale you see - a little bit of red can be a small problem like router bug or something.. a lot of red which comes and gows without a pattern suggests something going on on the network.
Your provider may try to fob you off but I don't think this is normal if the BQM graph matches your experience with other sites .. never rely on just one bit (e.g. BQM) to show a problem.. this is very useful lto illustrate the problem in a way you can share though.
The only thing I'd suggest you check is - can you get your IPv4 address (thinkbroadband.com/ip) and set up a BQM to that - see if the pattern matches. I don't know if NowTV have CGNAT which would stop this from working but it would be good to verify if the issue is IPv6 only or affecting everything. You had one set up in May as "NowTV Broadband 5" on your account with IPv4.. then it wen to v6.
The other thing you could try is disabling IPv6 on the router and see if you have the same problems on your system.
IPv6 isn't the cause but its routing is different from IPv4 so one problem may not appear on the other side.
One final thing - it appears you had a resync of some kind at 02:00 exactly .. your minimum latency doubled from 10ms to 20ms or so.. at the same time there was heavy packet loss.. this indicates to me the router did something at that time..
I just checked your IPv6 address from another system to rule out the BQM tools:
299 packets transmitted, 299 received, 0% packet loss, time 59825ms
rtt min/avg/max/mdev = 18.103/20.745/137.896/10.090 ms
This shows no loss (red) but it shows the yellow spike (137ms)..
