Sub panel or Tandem breakers

My main panel is full. I would like to add 3 to 5 more curcuits for basement. 2 electricians said sub panel, 2 said tandems, not sure which way to go.

What Mdl.panel do you have? There is nothing wrong with tandems if the panel is rated for them,but my vote would be for a sub panel if you have the space.

If your panel accepts tandem breakers, that's the way I would go as it may be much cheaper. Not all panels allow tandem breakers, check either the panel label or panel model number. If total circuits is larger than slots, then you can use at least some tandems. Some complications you may run into is if you have to use GFCI or AFCI breakers, which are not available in tandem size. In that case you might need to shuffle a lot of other circuits around in the panel to make room for the full size AFCIs.

What are the 3-5 circuits for?
