Pilot light problem?

Have a Glow-Worm Space-Saver 45-60 B, Boiler.
The pilot light has a intermittent tendency to go out. Is this a cleaning problem or is a spare part required ?

Thanks Mr K
Boiler descaled, radiators flushed out and thermocouple replaced.
Worked fine for a few days with both water and central heating on.

Now water heating function perfect when used without Central heating.
With water and central heating on, radiators reach required temperature and main burner closes down the pilot light is extinguishes as well.

Thanks Mr K, Think it must be the Thermocouple needing replaced.
As you say this model is very old so where will I get a replacement part, Our would a universal thermocouple fit?

Boiler is old and seems to have scaled up in heatexchanger. pilot will light and will go out after a while when boiler get hot due to overheat sence temp. and interupt the link to thermocouple to shut off. answer is to descal boiler only. or replace thermocouple and see if problem solved.
