If you are having TRVs on all rads (check with the boiler instructions that
you can do this), dispense with the wall stat.

You are a complete numpty.

Building regs require that you have a room thermostat and at least
TRV's on all radiators in sleeping areas (of course you can have
more).
They also state quite clearly that the use or TRV's alone are not
sufficient.

You are required to comply with the building regs if you make any
changes to your heating system to bring it up to standard.

Do you regularly fit systems like this? If so, the BCO would be very
interested I'm sure.
