You could have multiple lines with BT retail. You could use load balancing to multiply your speeds.

How would I achieve this? I guess I would need a special router?

Yes, something like this takes 2 ADSL routers and combines the connection http://www.netgear.co.uk/business/products/security/...

This does 3 lines http://www.peplink.com/balance/benefits/

Just recieved the router, connected it up, and my current stats are

Downstream: 4138kbps Upstream: 448
SNR: 6.2/17dB
Attenuation: 63.5/31.5dB

Great sync with that attenuation

It will be interesting to see how things go...


EDIT: As cost doesn't seem to be a problem for you, combining a few lines would seem to be the way to go as others have said...

From what I understand the lines that were run, where all the copper pairs run to the area, which is a surprise, as I would expect there to be a few spare pairs, to at least reduce cost to BT if a repair was ever needed.
