I am trying to set up a tunnel from my (O2 hosted) Home Broadband service in UK.
When I enter the public address of my router into the Tunnelbroker admin page I get a message saying that the address is not ICMP reachable and asking me to allow ICMP through the FW. I am going to guess that this will be fruitless and what I need is my own private IP within the home network that I can make ICMP reachable because my ISP is not going to let their router be ICMP reachable are they ?
That depends on the ISP.
There's probably a setting on your firewall that's blocking ICMP by default

I works for me on O2 BB 8) I'm currently using a Netgear DG834v4 router.
Are you using one of the O2 Wireless boxes?
If so then you need to allow ping (ICMP echo) responses on the WAN interface see http://www.o2help.co.uk/router-ping-responses/ (http://www.o2help.co.uk/router-ping-responses/)
There is also this thread http://www.tunnelbroker.net/forums/index.php?topic=2087.0 (http://www.tunnelbroker.net/forums/index.php?topic=2087.0) about timeouts blocking protocol-41.
