500k profile after disruption and new line install...

Question

Hello,
Status: 
I have an open fault logged with BT;  
Phone line ok but broadband speed low, profile appears stuck at 500k.
History: sporadic BBand connection and noisy phone line followed by outright failure of both.
Engineers visited and confirmed line between street and master socket probably corroded - they put it on leg+leg to get it working while we waited for a new physical line to be installed.
Pavement was dug up, new armoured cable run from street to house, and a proper master socket fitted (NT5 ? but no inbuilt ADSL filter).
In effort to ensure low noise, ALL other sockets in the property disconnected.
Digital phone (3 handsets off a single powered base) are run off the master socket using a filter.
Router is business hub - 2700hgv; f/w 6.1.1.48.1-enh.tm ,  h/w 2701-100589-005 .
Hub is connected to same master socket as phone (as it's the only socket now connected to the new line).
New line was installed approx 18 days ago.
Speed tests (speedtest.net) repeatedly show download of 480kbps, upload around 620kbps.
No change since new line was installed and all but the master socket decomissioned.
I use wireless to the router but also repeated tests with a Cat6 copper RJ45 cable and got same results.
Have taken all wireless devices offline and removed electrical items near phone line power supply and cable path to reduce potential noise and repeated tests.
I left the router on for two weeks and no increase in broadband speed.
I rebooted it twice this weekend to see whether it picked up a different profile - but no change.
BT speedtester repeatedly indicates a profile of 500k (full results further down).
Last year I had speeds about 512k on a DrayTek router before switching to the 2700HGV. The change to the BT hub upped the download speed to around 1Mbps, which made a huge difference.
I know I am "a long way from the exchange" but I've had 1Mbps last year and now have a new line into my property, so not much left that I can do to improve the situation.
I'd like to know what can be done to get me at least 1Mb download again.
I have an engineer visit due tomorrow but I believe that will be purely to finish putting paving slabs back over the armoured cable that's been installed (i.e. OpenReach dig team rather than line engineers).
After those slabs are done, I expect the fault will be closed but I'll still have a 500k profile and will need to raise a new fault all over again - that fault was opened 5 weeks ago.
Results of speedtester.bt.com run just now (1pm Sun 13th March 2011):
