I have a glowowrm ultimate 50cf boiler,lately the pilot light is going out when either the boiler has fired up for ten mins or so or sometimes as soon as the boiler fires up.Would this be the thermocouple and if so would a universal one be ok to replace it.

Try cleaning the pilot light- if there is a bit of dirt in the injector it can cause this problem-
