Does the sound change if you put it in gear?
Not that I'm aware, still does it when in gear and the car is just coasting but not when you accelerate. Hoping it is the drive plate as this is certainly better than an issue with the engine!

I meant in gear but stationary. This will put load on the plate and if the noise changes a bit then fair bet it's the plate.
 
That's too tinny a sound for big end bearings, it's called "knock" for a reason lol. That's a light metallic striking noise, I'm now inclined to think those members suggesting drive plate may be right. Deffo something loose though.
 
Thanks, I'll check!
You should be able to detect pretty quickly if it is the flex plate, when you remove the cover there will be red oxide type dust all about inside the bell housing, it is a result of "fret corrosion" and is created when two dry metallic surfaces rub together under high pressure where the cracking in the plate is.
The presence of this oxide would definitely point to a cracked flex plate.
