You need to check there is power to the boiler when the external controls are calling for heat first.

Have you any zone valves? Check these if no power present at the boiler.

Check for 240v at gas valve when everything is calling for heat, if itsd there just a new solenoid req and ten min job .
If not, as dave says you will have to be looking at motorised valves and programmer
