Start with the basics - power at the boiler , some sort of indicator light onthe boiler.
Water inthe system - try a radiator bleed screw to see if it squirts out.
Gas - trace from gas meter to boiler to see if valves are open. Don't open any gas valves if you find gas is turned off - get a gas safe man !
