Indeed it does and indeed it should to be compliant with current legislation.Incidentally on the benchmark checklist it does state "either/or" in relation to room stats and TRV's to comply

1. If I knock the TRV's on all other rads to a lower heat setting will this effectively mean more flow of hot water eventually reaches the living room rad?
Only slightly.
2. Or do I have to balance the system properly with the lockshield valves?
Much the better way
3. If so which ones do I start off with to work my way across? Ie all top floor first and then ground floor??

Although it refers to Drayton TRVs, and I doubt if your installer bothered to used that brand from your description of his workmanship, the principle is the same: the TRV needs to be disabled by removing the head and putting on the "decorators cap" (you do have them?) which is set to about a third open.
4. Which way would I turn the lockshield valves to lessen the flow? Clockwise or anti-clockwise?
Clockwise: reduces flow = increased temperature drop across radiator
Anticlockwise: increases flow = increased temp drop
You will need a thermometer to measure the temperature drop. You can get dial types (eg Brannan) but they are very slow reacting to temperature change and are not very accurate. I purchased an infrared one from Maplin for £19.95 (reduced from £49.95) and its just the job
5. I am hoping that I can sort of mimick this with the TRV's rather than getting a spanner out and mucking about
That is what some "heating engineers" hope as well.
Yes it is but, as has been discussed many times on this forum, it is a guide not a law.It is all explained in the Domestic Heating Compliance Guide at:

The reason it is a best practice guide and not enforceable as a law is that it has Should's rather than Must's which have entirely different legal implications ... Read it again and see what I mean.
See how many ... You MUST do this's you find and let us all know
