Engie business energy tariffs
This section summarises the business energy tariff types offered by Engie.
Guard
Engie’s Guard tariff fixes a single unit rate inclusive of all third-party charges for the duration of the contract. Available on standard and green business energy, electricity and gas contracts, prices are guaranteed for up to five years with Engie absorbing any market movement.
Simple
Engie’s Simple tariff applies a single fixed unit rate with no daily standing charge on standard gas contracts, meaning businesses pay only for the gas they consume. The rate remains fixed for the contract term regardless of any market changes, with Engie absorbing any movement in costs.
Balance
Freedom
Engie’s Freedom tariff fixes the wholesale element of the price while passing all third-party charges through at cost. Available on standard and green business energy, electricity and gas contracts, businesses avoid risk premiums on pass-through charges and can benefit from any reductions during the contract term.
Flexible purchasing
Engie offers flexible energy contracts for larger electricity customers seeking direct control over wholesale electricity market purchases. Options include market-reflective pricing, multi-rate structures that cover seasons and times of day, and weighted-average invoicing for businesses with expected annual consumption above 10 GWh. Volumes can be purchased across specific months, quarters, or seasons to take advantage of market movements.
Green energy
Engie supplies green business energy electricity backed by Renewable Energy Guarantees of Origin (REGO) certificates and certified green gas tariffs that deliver biomethane with at least 46% fewer carbon emissions than standard gas. Electricity options include UK Green, UK Green Plus, and Green Select, a long-term power purchase agreement linked to a specific UK renewable project.
Engie Business Energy contract features
Our business energy team has reviewed the Engie business energy Terms and Conditions and summarised key contract features:
Payment Methods
Engie provides flexible payment options, including direct debit, to cater to various business needs. Businesses can choose the payment method that best suits their operational preferences. Specific SME tariffs may require Direct Debit as the primary payment method.
End of Contract
When your Engie contract approaches its end, Engie will notify you of your renewal options, allowing you to transition seamlessly to a new plan without interruptions. If you do not choose a new agreement, your account will automatically move to Engie’s Default Contract Rates.
Credit Checks and Security Deposits
Engie conducts credit checks at the start or renewal of a contract to determine appropriate payment terms. Depending on the credit assessment, a security deposit may be required. This deposit is refundable at the end of the contract, less any outstanding balances.

Engie ensures the provision and maintenance of metering equipment, including smart meters and half-hourly meters, which enable automatic meter readings.

- Contract termination problems: Businesses have highlighted challenges in terminating contracts, with Engie continuing to bill despite contract end requests.
- Demand for immediate payment: Some reviews mention abrupt payment demands with short deadlines, adding stress to billing disputes.
