Rads have TRV's ..... There is a wall thermostat in the hall at bottom

Is the thermostat in the right place ?

Almost certainly not.

Such a thermostat should be placed in a location which reflects the
external temperature, will not be influenced by internal heat gains
and will cool down most rapidly when heating is off.

An ideal place is a north facing bedroom. Living rooms are best
avoided as they may have supplementary heating, kitchens are best
avoided as they have cooking equipment in them which (one hopes)
will give off heat.
