This may be more complicated than it seems. Basically you will be paying for two lots of electricity – one for common property through your levies and the other for personal usage. The personal usage charge could include an element for the hot water that you have run through your taps. Or not.
And the common property charges could be locked into a long-term embedded network contract that can’t be changed for a few years. Or not.
Everybody has a slightly different set of circumstances so the best thing you can do is talk to someone on your strata committee and ask them what all the charges mean and how much flexibility you have with changing energy providers.
You could be free to go to whomever you like for personal power, and your common property deal could be coming up for renewal. You might even be getting a better rate for that through your strata manager. Like I said, it’s complicated and the set-up in your block could be very specific.
As for getting a broker, it might be just as good to do a quick trawl through the comparison websites. Simples, as the annoying meerkat says.
