Dear Liam here are a few possible causes but this is usually caused by a problem with the safety thermocouple there is usually a thermocouple that is designed to be in the pilot light flame (it normally looks like a small metal cylinder with wires leading away from it) if the thermocouple isn't hot enough, that indicates that the pilot light has been blown out or something, and it is no longer safe to keep feeding gas to the pilot light (it isn't burning so the gas could fill up a room and cause an explosion) there are several reasons why the thermocouple might not be registering the temperature 1. the pilot light gas nozzle is partially plugged and so the flame is not as big or as hot as it should be and isn't heating the thermocouple (sometimes you can clean the nozzle with a pipe cleaner or one of these cans of pressurized air) 2. the thermocouple has moved (been bumped or broken) and is no longer in the right place to be heated by the flame 3. the thermocouple wire is broken or unattached at the other end If it isn't the thermocouple, then it may be the gas valve itself which is usually not repairable and kind of expensive to replace it could, of course, also be something else good luck
