make sure that all the electrics to boiler and clock are switched ON...... check the clock and see if you can manually override it to ON.....make sure any room thermostats are wound up to a higher setting so that they "call" for heat and switch the boiler ON...check any boiler thermostat on front of boiler to make sure it is turned up enough..check to see if your pump is running or whether it has seized/stopped...if still not coming on then you will have to seek professional help.(or get the plumber back who fitted your bathroom radiator 0...if it has just failed then the problem is most likely due to something electrical ..and quite often something has been switchedOFF in error..or the fuse/mcb in the consumer unit in the meter cupboard blown /tripped or removed + not replaced .
