Heating Checks

Radiators are not working.

Is the programmer calling for heating* (have you turned the heating on)?

Is the room thermostat calling for heating* (have you turned it up)?

Are any of the radiators coming on?

Are the radiators that are working upstairs or down?

They maybe airlocked, try turning off all radiators by their valves - leaving only one on. Repeat for each affected radiator until working.

Are the radiators turned on at the valves?

Try bleeding the radiator(s).

If you  found that you answered yes to a "is it turned on?" type of question but it still wasn't on or working then  further checks are required. Steps with * may require electrical testing to further prove if at fault. These checks are not covered in this basic checks section.
