• Do you have any play in the hubs? Grab the rim, can you move it easily? Will get chatter if your hubs are loose - might have worn bearings etc. Have you check for broken spokes?

    Lift the front wheel of the ground a few cm by grabbing the bars, when you drop the bike, is there chatter? Can you locate it?

    Sounds like you do need to get someone who knows a little about mechanics to look at it. Try phoning around your LBSs to get it booked in for a service (or at least an apprasial). I'd happilly come and have a look at it for you, but I don't live in London.
