Boiler making clicking sound?

I have a glowworm ultimate boiler, it has been fine prior to the past few days, sometimes just before it fires it makes a clicking noise like a chatering relay for a couple of seconds then it fires up. I have took the cover off to look and there is a unit with the gas pipe going into it that makes the noise. Is this some form of regulator/gas control swithch ?.

its the igniter

Not nessasarily the gas valve playing up, or something a gas fitter is needed for. Mine did this too, I located it to a poor connection on the temperature selector (the slider potentiometer you select the radiator temperature with). Replaced the potentiometer... and no problems....

It's not a sticky gas valve - if it's chattering, it's because the relay driving the gas valve is chattering because the electronics on the ocb is faulty

... corgis

sounds like your talking about your gas valve. it maybe getting abit sticky.
but that comes under corgi.
