I can tell you in principle how to do this. But the BT HomeHub is a piece of sh*t that shouldn't be allowed because it has no easy user configurability.
In principle, the second router (not the HomeHub) should be set up in WDS mode to wirelessly see the HomeHub. It may be Home Hub version sensitive. Worth a try.

You've got some research to do.
Incidentally, when I had BT Broadband, I used my own router (Draytek 2800) which is fully configurable and is known to support WDS with a bridging router elsewhere in the house. Do it (better models than the 2800 available now) and stuff the wretched Home Hub. One advantage of having your own router is that when you reset it to factory default, you don't have to ring BT to restore your connexion. What were they thinking of.
