Corona Energy is a UK business gas and electricity supplier focused on SMEs through to large multi-site organisations. They offer standard (“brown”) supply, a fully renewable option called ECOrona, and account tools for billing and metering.

A Fixed contract locks your unit rates and standing charges for the term — ideal for budgeting and stability.

A Standard contract starts cheaper but passes through certain costs (like network or regulatory fees) if they increase during your term. It’s more exposed to market movements.

If you value price certainty, choose Fixed.

If you’re comfortable with potential cost swings and want a lower starting rate, Standard may suit you — though it carries more risk if wholesale or non-commodity charges rise.

ECOrona is Corona’s 100% renewable electricity product, backed by Renewable Energy Guarantees of Origin (REGOs). It’s ideal for businesses looking to demonstrate sustainability and reduce their carbon footprint.

These are the “hidden” industry costs that make up most of your bill — such as distribution, transmission, and environmental levies.

In Standard contracts, increases in NCCs are passed on. In Fixed contracts, most are locked in at the start of your term.
