Sorry not replied sooner, busy at work
On Vivaciti i got around 2.5-4 meg sync, variable day to day and on a good day up to 6 meg (rare) on 59db attenuation.
From the BT checker (with ADSL info for comparison):

Your exchange is ADSL enabled, and our initial test on your line indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 1Mbps. However due to the length of your line the 1Mbps service may require an engineer visit who will, where possible, supply the broadband service.
Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 2Mbps; typically the line speed would range between 1Mbps and 3.5Mbps.
Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 2.5Mbps; typically the line speed would range between 1Mbps and 4Mbps.
Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 57.5Mbps and upstream line speed of 20Mbps.
