At this point I can't rule out some misconfiguration on my part but its something I hope to discover if it is the case.
I'm using the following IPs as DNS servers:
194.73.73.172
194.72.6.57
208.67.222.222 (open DNS fallback)
I've also tried a number of other BT and non BT name servers with little change - my router needs them hand configured if its acting as a DNS server/relay to local clients and BT don't make it easy to work out which you should be using.
First up is loading the bbc.co.uk website - I'm using firefox with the fasterfox extension to time the page loads - times are in seconds.
Direct connection:
24.781 (no cache)
20.188
12.469
35.310
Proxy via VPN (SSH tunnel).
2.875 (no cache)
2.796
3.343
2.594
Peak time speed test is hardly inspiring either:

And neither is the BT speed test:
Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 4448 kbps(DOWN-STREAM), 896 kbps(UP-STREAM)
IP profile for your line is - 3500 kbps
Actual IP throughput achieved during the test was - 862 kbps

Exchange is showing green on status checks.
The above info does suggest that the connection is both traffic managed and there is extreme congestion within the BT network (even ~1-2 months ago I'd ping bbc.co.uk ay 7-8ms in peak times) - but neither of those would explain directly why HTTP traffic over the BT network is 10x slower than HTTP traffic via an encrypted stream - which suggests they are parsing such traffic in some manner either via phorm or some kind of proxy or DPI - with a system thats completely incapable of handling the load.
