As the others have picked up, you seem to be on partial LLU, (which the failure of the BT test indicates - which is why I asked you to try it), but with much lower downstream connection speed than would be expected from your attenuation.
You didn't say who your line rental is with? If it's AOL it doesn't tell us much. If BT or most others, it guarantees it is not full LLU. Only with full LLU would you not need a MAC.
However, there looks to be more than one factor preventing you getting the 15Mbps or more that a 31dB attenuation often reaches. Your noise margin is high, but nowhere near what it would be if you were not being restricted in some way or other. Is your package supposed to be "up to 8Mbps" by any chance?
Do you think you could power down the router for 10 minutes some time during daylight, then take the stats again immediately after you get reconnected? That should give us a bit more info, in particular the DSLAM setting for the target noise margin.
What's concerning me is that there may be some problem that could have a bad effect on FTTC if you go for it. Though in most cases the engineer installation procedure cures things.
Or of course, if you could get 15Mbps by an ADSL2+ upgrade or migration, you may be interested in that. Getting the current issues resolved could be a fair bit of hassle though.
In view of your earlier description of the usage in your household, FTTC would be your best option. Both BT and Sky, (if Sky FTTC is available), require you to have your line rental and calls with them. Most others aren't so fussy. You might find this page
