Out of interest, were you getting similar 2 meg-ish speeds before your line was slowed down?
Have you tried using one of the availability checkers online to see what is expected for your connection / area? Personally I'm a fan of using the one over at the kitz website.
Please feel free to send me a PM if you'd like me to have a look at your line.
Thank you Andy, PM sent,
My speeds have fluctuated for ages now, even before being slowed down. Today (Daytime) for example typical download speeds have been 1.4, 1.8, & 2.0Mbps, all 0.4 upload. Then this evening I lost my broadband altogether for about an hour. Then it came back on and I have done a 3 tests this evening resulting in 3 same results.

BT Line Speed Estimation from Kitz..
Fixed ADSL: 2048 kbps (2 Mb)
DSL Max: 4000 kbps (4 Mb)
21CN WBC : 5500 kbps (5.5 Mb)
What do you make of that?
