Well it was sitting there all night trying to download the installation components without success. There is an error log but I can't seem to save it.

Is there a correct way of partitioning the HDD before I attempt installation again if that's the problem?

I have 1 partition (GUID).

Thanks
Daz

As an update I pulled the USB stick out the back and restarted. It's now again downloading the additional components. It got down to 0 seconds remaining (yes zero!) and is now climbing back up to 3 hours or so!

On the install log (it's still downloading additional components) I did see:

failed to verify InstallESD.dmg hdiutil verify failed

It's now retryting pisa (whatever that is)

For the primary partition for OS X you should be using 'Mac OS Extended (Journaled).'
