Painfully Slow Broadband

Question

Good afternoon to all
Another pretty standard post for this forum really - I'm with BT Broadband and have been for quite some time. This is a problem we've had for the entire time we've been with BT and sadly contacting them via phone hasn't helped us at all. Through the estimated speed checker offered by both BT and other sites, we're estimated to be between 3.5 and 5mb broadband. What we're actually getting is far, far lower at around 2.2mb. We've checked all the wiring in the house, replaced all the filters, and even when the router was upgraded to the HH3, no change in speed whatsoever. The connection is rock solid, only ever resetting itself when we've had power cuts - so from what I can glean, there ought not be a problem regarding a stuck IP profile. I don't live in the middle of nowhere, so it's especially frustrating when somebody who lives just 1/4 of a mile away form myself and is also with BT gets a standard 15mb speed.
If anybody can offer some insight in to the problem or a way to possibly combat it, I'd be greatly appreciative. Thanks.
For what it's worth, here's a copy of the line status details (the connection time is short due to a power cut yesterday). If anything else may be needed, please ask.

I had a quick look at the bellwire suggestion - this is definitely food for thought, however I do have an older style socket so I am not technically allowed to remove the plate. Thank you however!
John46 - thanks for replying too. I have done a quiet line test, and it came back perfectly silent. I also did the speedtester test and the results came back pretty much identical to how they do whenver I try that one:
1. Best Effort Test: -provides background information.
Download  Speed
1.87 Mbps
0 Mbps
2 Mbps
Max Achievable Speed
 Download speedachieved during the test was - 1.87 Mbps
 For your connection, the acceptable range of speeds is 0.8 Mbps-2 Mbps.
 IP Profile for your line is - 2 Mbps
2. Upstream Test: -provides background information.
Upload Speed
0.72 Mbps
0 Mbps
0.83 Mbps
Max Achievable Speed
Upload speed achieved during the test was - 0.72Mbps
 Additional Information:
 Upstream Rate IP profile on your line is - 0.83 Mbps
