Typical Tariffs and Rates
Corona Energy offers competitive fixed-rate contracts. A typical electricity contract comes in at £0.15 per kWh with a £50 per month standing charge.
They provide two main contract types:

- General operating costs
Invoices show these charges as pence per day (standing charge) or per kWh (consumption rate).
Direct Debit and Payment Methods

Their online account management system lets customers keep an eye on usage and sort out payments digitally.
Invoices break down the costs clearly, separating standing charges from consumption charges.
Payment terms and methods can vary depending on the contract. Larger commercial customers might have different arrangements compared to smaller businesses.
Factors Influencing Energy Costs
Several things affect Corona Energy’s pricing beyond just the tariff. The Climate Change Levy (CCL) applies to both gas and electricity for business customers.
Environmental levies include:
- Green Gas Levy for gas
- Renewables Obligation charges for electricity
- Contracts for Difference costs
Network charges depend on your location and cover distribution and transmission fees. These help keep the grid up to date.
Meter operating costs come down to the kit installed at your premises. Automated meter reading charges apply if you’ve got smart meters or AMR systems.
Contract length impacts pricing stability. Fixed-term agreements help protect you from market price swings during the contract.

Steps to Switch to Corona Energy

- Submit readings through the myCorona portal
- Email the myCorona team if you can’t log in
Corona Energy sorts out most of the paperwork and admin, making the switch pretty painless.
Contract Lengths and Exit Fees

Standard contracts have variable costs that can change with the market. Fixed-rate contracts lock in your price per kWh and standing charge for the whole term.

- Standing charge: £50 per month
Contract terms depend on your business size and how much energy you use. Bigger businesses often get better rates and more flexible options.
Exit fees and cancellation policies differ by contract. It’s worth reading the terms carefully to avoid unexpected costs if you switch again later.
Eligibility Criteria for Businesses
Corona Energy serves business customers across a wide range of sectors and sizes. The company creates contracts for all sorts of commercial energy users.
Small businesses can get tailored contracts through the usual switching process. Medium and large companies often receive bespoke pricing based on how much energy they use.
