John2007 Thanks for that.

my "Attenuation" is 32Db, site says I can get between 10-14Mbps.

Current line sync: 7168 I think
(my livebox says this is downstream rate, don't know if this is the right number)
Attenuation: 32db
Noise 6.6
Results are:-
We estimate that if using a rate adaptive up to 8Mbps service your maximum line speed will be: 7168kbps.
If you are on a Max product, that uses the IP Profile system (sometimes called BRAS Data Rate) if you maintain the above line speed for 3 days or more your IP Profile would be set to: 6mbps.
If your service provider uses ADSL2+ we estimate you may manage line speeds of: 15,650.
With ADSL2+ the maximum IP throughput is likely to be around: 13,850kbps.
So I think the answer is that I'd get up to 6Mbps with a non LLU provider like Waitrose/Madasafish, but could get 10-14Mbps with an LLU provider like "Be".
Hmm, interesting, but I still think I may go with Waitrose as they've got such good reviews and support should be good. Also "Be" do seem to be having problems at the moment. Worrying though that BT have bought the company that supplies Waintrose & Madasafish (Brightview).
I still have a bit of time to decide anyway, as have to wait for MAC code from Orange.
