Questions people ask
Is ATCO cheaper than ENMAX?
Neither is cheaper for every home. The table shows the range of their energy prices where the published prices support one. Your total depends on your usage, delivery charges and fees. A free bill check compares costs for your home.
Which is better, ATCO or ENMAX?
We do not rate companies. Neither company is better in every home. What decides the cost for your home is your electricity and gas use, delivery charges for your address, monthly or daily fees, and contract terms. Compare those details against your bills before you choose a plan.
Can I switch from ATCO to ENMAX?
You can choose a competitive retailer if you control the energy account and the plan is available at your address. Check your current contract for notice periods and any exit fee. Confirm the new service start date and the old service end date with the retailers before making a change.
Does switching change who delivers my power?
No. Your address sets the company that owns and maintains the wires or gas pipes. That delivery company stays the same when you choose a different competitive retailer. Your energy price, administration fees and contract terms may change. Delivery still follows your address, whichever retailer you choose.
