"Anytime I switch energy plans, I look out for energy deals while searching for the cheapest plan. When I switched to AGL, it was one of the cheapest options for both electricity and gas for my postcode and it was offering sign-up credits which would help lower my bills even further. The main thing I've learnt is that a provider may be offering a good deal but it won't save you money overall if its plan prices aren't one of the cheapest around."
