I've got a customer who owns a house divided into 6 x 1 bed flats. The top
floor flat rad is completely cold. Water comes out of the bleed as usual.
The occupants of the other 5 rooms are all complaining that their rads get
far too hot.

All the rads seem to have a lockshield on both ends, so can't be adjusted.
Why would that be?

I could only check the rad in the flat below the top one, which was red hot,
both valve fully open.

Combi boiler pressure was down a little & output set at 56 degrees (LED
display).

I reckon the problem is the lack of adjustment on each rad, poor bugger on
the top floor is loosing his share of heat to the over hot other 5.

Can you buy replacement wheelhead caps in any of the sheds?

Or is it another problem?

So adjust them with an adjustable wrench to prove this. Turn some rads on
the lower floors down to see if you can kick start the top floor.

The ideal solution would be to balance the heating system then fit TRVs.
In this situation it's reasonable to pin the TRVs to a restricted range
to prevent room taking on too much heat. An earlier version of which is
to provide two lock shields so the inmates (oops I mean) users can tamper
with the carefully and skillfully setup heating (yeah right).

In practice all you are going to be allowed to do is to restrict the rads
which are too hot. I would check that the radiator at the top is properly
on at both ends.
