What could be the possible causes?

    Might need more info. Just to check - switches off by itself? Do you have TRVs on radiators? My guess is they are warm enough and shutting off, so the water return temperature is high(er) and boiler is turning off. Does it come back on by itself when the temp drops?

    I am guessing you mean the boiler switches itself off. If so, there is a fault on the boiler that causes it to turn itself off. Time to call the repair man.

    Faulty thermostat, pressure or the circuit board or whatever it's called needs changing. Either way you need to get someone in to check...
