If you're with ENGIE and currently out of contract or on deemed rates, it's crucial to understand the charges you're incurring. ENGIE publishes separate default rates for gas, non-half hourly (NHH) electricity, and half hourly (HH) electricity supplies. As with other suppliers, these default rates are typically much higher than fixed-term contract prices.

⚡ Why Out of Contract Rates Cost You More


ENGIE's OOC rates are significantly higher than competitive fixed-term deals. While they’re 100% green and fully transparent, they’re not intended for long-term use.


Remaining on these rates can result in avoidable costs, especially if your usage is high or your site qualifies for large-volume banded charges.



Switching to a fixed-term contract typically reduces energy costs by 40–70%.

Avoid paying more than you need to.
