In this section, we summarise the business energy tariffs offered by Corona Energy.
Corona Energy offers fixed-rate electricity and gas contracts for businesses that want certainty over their energy prices. The unit rate is agreed at the start of the contract and remains fixed for the full term, helping to protect against fluctuations in wholesale energy markets.
Corona Energy also offers a flexible energy contract for businesses with larger or more complex energy requirements. Under a flexible arrangement, energy can be bought in tranches over time rather than securing the full volume at one fixed point.
Corona Energy also offers green business energy options for businesses looking to reduce the carbon impact of their power supply. These tariffs are backed by Renewable Energy Guarantees of Origin certificates, which confirm that the electricity supplied to the grid has been generated from renewable sources.
Our business energy experts have reviewed the terms and conditions for Corona Energy to highlight the key contract features businesses should be aware of before entering into an agreement.
Corona Energy typically requires payment by Direct Debit, unless alternative arrangements have been agreed in writing. Bills are typically issued on a monthly basis and made available through Corona’s online account system, with customers responsible for ensuring invoices are checked and paid by the due date.
If a Direct Debit fails or payments are not made on time, additional charges such as late payment interest or administration fees may apply.
Fixed-term contracts run for the duration agreed in the contract confirmation. Businesses must provide notice within the timeframe set out in their agreement if they do not wish to renew.
Corona Energy issues renewal communications ahead of contract end dates, outlining new prices and relevant notice deadlines. If a termination notice is not received in time, the contract may roll onto automatic renewal terms or out of contract rates, depending on the agreement.
Corona Energy may carry out credit assessments before accepting a contract and may review credit status during the supply period.
Where credit criteria are not met, the supplier may request security deposits, advanced payments, or amended payment terms. If a business’s financial position changes significantly, additional security may be required under the contract conditions.
Businesses can switch business energy suppliers at the end of their agreed term, provided they have given valid notice and there are no outstanding contractual barriers.
Corona Energy may object to a switch where there are unpaid charges or where switching would breach the terms of the agreement. Customers supplied under deemed or out-of-contract arrangements are generally able to switch, subject to settling any outstanding balances.
Customers must provide reasonable access to electricity and gas meters for inspection, reading, maintenance, or replacement. Where actual readings are not provided, bills may be based on estimates until confirmed readings are received.
Corona Energy supports the rollout of smart meters where suitable and may arrange installation where required. Failure to provide access could result in additional charges or continued estimated billing in line with contract terms.
Corona Energy holds an Excellent Trustpilot score of 4.5, reflecting strong overall satisfaction among business customers. The points below summarise common themes raised in independent customer feedback.
