After 10 minutes of driving, the drivers headlight starts working... so could it be that the battery is a bit low (it can be 5 days between drives and I have not yet got a trickle charger fitted) and it is somehow cutting power to the drivers headlight until the battery has charged enough...

If it is not that, then I don't know what...

Thoughts?!

If this is consistent time wise then it's likely more suspicious I'm afraid. Symptoms don't suggest a battery volts issue.

It would do no harm to check check connections on headlamps though as per Jon's comment. Check fuses as well. Later cars have individual fuses for each side and dip and main beam so there are four just for headlamps.
