    would help if you gave the name and model number of the boiler as they are all different
    have you checked to see if you actually have gas?

    thanks, yes I guess so as it lights initially?
    Its a Glow-worm hideaway, cant find any serial no or anything, sorry!

    It is probably a new thermocouple that you need but it has to be fitted by a gas engineer
    Hope this helps

    When mine wouldn't stay on it was the thermocouple but it just needed cleaning, so it just cost me the cost of a call out.

    A couple of years ago it cost me about £20 I think

    Okay, that sounds less ominous, thanks

    No, I thought by your post you had resolved it.
    Sorry.

    No problem, besides I like looking at your House picture!!!, so no ideas of how to clean it then, have hoovered just now and no luck, so it looks like an engineer then. But I appreciate the help.

    The pilot light is lit 24/7. It's a constant burning stream of gas.

    If the pilot light were to blow out, for whatever reason, the gas would then start leaking from the boiler resulting in suffocation of room occupants or an explosion.

    To prevent this, they fit a safety device on the gas supply. The thermocouple, as hinted by the name, detects and reacts upon heat. It sits literally in the flame of the pilot light and gets hot whilst you hold in the knob on the ignition. When you let go, the thermocouple is hot and the gas continues to flow. If you let go too early, the pilot light goes out.

    Should the pilot light go out, the thermocouple goes cold and the gas supply is shut off for safety.

    As the thermocouple is sat right in a flame all day every day, it's going to wear pretty quickly and will need replacing over time. When it's broken, the pilot light will keep going out for no reason. This appears to be your problem.

    It's illegal for an untrained person to tamper with any gas device to try a DIY fix. If you can't relight the pilot light with the knob, just call out an expert.

    we had the same problem last year when we came back from holiday. It was the thermocouple that need replacing, think it cost £60 to have someone out to do it

    Yep as people have said, thermocouple or blocked injector in the pilot light, if the injector gets blocked the flame of the pilot light wil be too small to heat the thermocouple and so this won't keep the gas valve open, very simple job, half hour at the most

    My old boiler would not light again when the pilot went out if the water pressure was below 1. So I had to up the water pressure and it would light again. It was a dodgy boiler tho so might have just been mine. Glad to have moved and not had any boiler problems since!

    pilot light thermostat faulty, very easy to remove 2 minutes only, 10mm spanner should do it .take it off go to b and q ,only 5.5 quid for a new one i have just replaced mine today . it is a copper curled up wire that tells the boiler when to switch on or off.they tend to burn out at the end after a while ,as i said a 2 minute job and will save you a lot of cash .no gas or electrics involved in the process.anyone can do this honest. good luck
