I have a squeak that i can hear while i drive. I'm fairly confident that it isnt a belt squeak because it almost sounds as if it is coming from below the car. The only clue I can give is that there is no squeak in neutral. Only when the car is moving. But the squeak goes away when i put even the slightest amount of pressure on the clutch. Any guidance would be muchly appreciated. Cheers

Throwout bearing.

Thank you! 

Edit: after a little research into the symptoms of a bad throwout bearing. It would appear that this is not the issue. The search continues!

If you're quite confident in this then it limits the options-

Clutch pedal/pedal box vibrations

Does it have a cable?? A likely source of squeaks if it does, it vibrates a lot when relaxed.

Clutch arm going into the gearbox. Does it have a spring pulling the clutch arm back off the pressure plate?

Thrust bearing

Spigot bearing

..and that pretty much cover the components that get affected when you press the clutch pedal.  Something may be making the noise as the result of the general engine vibration, rather than being worn itself. Also notable that its only when the car is under motion, when the motor and components are tilted under force compared to relaxed in neural. That makes it hard to crawl around searching for it.

Second the throw out bearing solution. Doesnt hurt to check your oil level, when they run dry they will make a similar sound but sometimes doesnt go away when clutch is depressed.
