Glow Worm space saver boiler pilot light is alight but wont fire up when thermostat calls for heat

Check across the gasvalve with a multi meter.I think the spacesaver has a 24v gasvalve fitted.If you have got 24v then im afraid the solenoid on the valve has gone.If there isnt 24v then it is a power problem.These also have a transformer inside which i have changed in the past but the fav is the gasvalve.
