Which PES / Distribution area you are in has a significant effect on your energy charges. This applies to standing charges, availability charges as well as unit rates. Unfortunately it’s also something you can’t change, short of moving your business. It also dictates who you will need to contact to upgrade or downgrade your supply or if you are looking for a new supply. Not your region? try our PES Area search.
