Boiler make and model ?
Probably needs replacement thermocouple, you cannot fit these yourself, you will need a CORGI registered installer - not a plumber as advised by ericmark.
Not quite sure what ericmark is talking about or advising, there's no electrical connection to a Thermocouple, it's made up of two metals, when heated produces a small electrical current which then holds open a thermo-electric part of the gas valve.
