Right, so one of the things that has been increasingly annoying me was the rattle/knocking coming from the front. I know the previous owner, Chris, had the same issue, had it checked over and nothing ever came of it. It didn't really bother me at first but now that I do drive the car a bit more, it does grate after a while.
Anyway, to cut a long story short I've discovered it is the brake pads rattling in the callipers. The noise goes away if the brake is pressed. After a short investigation I've realised I don't have the spring retainer clip things that secure the pads in place. The pins are obviously there, but not the spring clips:

One issue with aftermarket stuff as you all probably already know is it isn't as easy as do a google search and order online! Sent a few enquiries out and found a place that have them.
Will report back once installed to confirm 100% whether the noise has gone but I'm pretty confident it will.
