Well, your system certainly wouldn't satisfy the latest building regs on

The boiler will turn itself off. It has its own stat on teh water temp.


Yes but that is not enough to comply with Part L whcih the OP does not
have to do since this is not a new replacement.


The simplest solution is to install a room stat - which really needs to be
in a room whose radiator *doesn't* have a TRV - otherwise they will fight.
You could probably put it in the hallway, and leave the TRV on that rad
fully open - or, even better, swap it for the conventional valve on the
bathroom rad.

Agreed this is simpler that going for all TRVs and 'smart' bypass units
with interlocks.
