those stats seem to indicate a 40/10 service

I was thinking that, but the max attainable is still below the handback threshold

Almost certainly on 40/10 ... the attainable at 46 is also way below what should be expected from your line. 16dB suggests around about 400m, slightly longer that on the map, and it should have an attainable in the 70 to 80 region but the noise figure at 6dB points to a high noise level. What sort of businesses are there on the way?

Loads of businesses between the cab and here.

at least 3 shops, 3 takeaways, florist, ice cream place etc.

I'll get onto BT and get them to check if the service is provisioned as 40/10 or 55/10

If i put my address into the bt.com predictor I get a lowest "assured" speed of 49, so event he max attainable is below that

You will find it is 40/10 - the 39.x sync well below the 46 attainable demonstrates that. If you were on a 55/10 then sync would be around 46.

Check your stats hourly, particularly SNR and Sync - do they vary overnight or in the evenings. Get DSL stats running and let it monitor for 48 hours if you can and also use the online facility so we can see your data. That may give some clues.

Does DSL Stats support the Hub 6?

If not I've got a HG612 somewhere I can use

No, the Hub6 doesn't work with dslstats
If not I've got a HG612 somewhere I can use

The Hub6 doesn't work with a modem unless you have the FTTP version of the Hub6 with a WAN port.

I'll put the HG612 into my UBNT EdgeRouter and UniFi AP

It was my understanding that the max attainable was set by the DSLAM and not dictated by the package selected by the ISP.

If thats the case, then is there a reason why the attenuation would suggest 70 attainable but the modem only thinks 46 is attainable?

As I said NOISE ... The DSLAM will keep dropping the attainable rate until the 6dB SNR is reached.
