Corona Energy: Compare Business Energy Deals Online

Corona Energy is a leading independent energy supplier that focuses exclusively on the commercial, industrial, and public sectors. Since its founding in 1995, it has grown to supply approximately 14% of the UK’s industrial and commercial gas market. Backed by the global financial expertise of its parent company, Macquarie Group, Corona Energy remains a preferred choice for businesses that require high-level transparency, flexible procurement, and reliable digital management.

Unlike Big Six suppliers that split focus between households and shops, Corona is built from the ground up for the specific demands of business operations.

Why Choose Corona Energy for Your Business Energy?

Corona Energy has carved out a niche by offering a corporate-grade service to businesses of all sizes, from SMEs to large-scale industrial portfolios.

• Sector Specialist: They exclusively serve businesses and the public sector, meaning their customer support teams are trained in commercial billing, VAT declarations, and industry-specific regulations

• 100% Renewable Options: Sustainability is a core pillar of their offering. They provide 100% renewable electricity and renewable gas options, helping businesses lower their Scope 2 emissions

• Automated Meter Reading (AMR): Corona was an early pioneer of AMR technology. All SME customers receive smart meter installations as standard, ensuring that estimated bills are a thing of the past.

Business Energy Tariffs Breakdown

Corona Energy provides a Matrix pricing structure that allows for rapid quoting while still offering the flexibility required by complex commercial entities.

1. Small and Medium Enterprises (SMEs)

• SME Fully Fixed: This is their most secure product. It locks in the unit rate, standing charge, and all third-party non-commodity costs (like grid fees) for up to 3 years. This provides absolute budget certainty in a volatile market

• SME Fixed: A slightly cheaper option where only the energy element is fixed. Third-party industry charges can fluctuate, meaning your bill may change if regulatory fees rise

• SME Variable: Ideal for businesses that want zero commitment. There are no exit fees, and you can switch at any time, though rates are generally higher than fixed deals

2. Large Business and Corporate

For high-demand users, Corona offers sophisticated Flexible Purchasing models. This allows energy managers to buy their power in tranches throughout the year, spreading risk and taking advantage of market dips rather than locking in on a single day.

Sustainable Energy Services

Corona Energy has expanded its service suite to help businesses navigate the UK's evolving energy infrastructure:

• Site Works & New Connections: Unlike many suppliers, Corona has a dedicated Site Works team that manages everything from meter removals to the installation of new gas and electricity connections for expanding businesses

• Environmental Reporting: Through the myCorona portal, businesses can access detailed carbon reports, showing the exact environmental impact of their energy consumption—critical for ESG audits

• Public Sector Excellence: They hold significant contracts with major public sector procurement frameworks, proving their ability to handle massive, multi-site energy requirements under strict regulatory scrutiny

The Procurement Process: Moving to Corona Energy

1. Fast Quoting: Because of their bespoke pricing matrix, Corona can often provide a firm quote within 48 hours of receiving your business details

2. Credit Assessment: As a commercial specialist, Corona will perform a business credit check. In some cases, a security deposit may be required for startups or businesses with lower credit scores

3. Smooth Onboarding: Once the contract is signed, Corona handles the termination of your old supply. They are known for a frictionless onboarding process that keeps the administrative burden on the business owner to a minimum

Pros and Cons of Corona Energy Business Energy

The Pros

• Transparent Pricing: They provide a clear breakdown of wholesale costs vs. industry fees, which is rare among smaller independent suppliers

• High Customer Satisfaction: Consistently high ratings on Trustpilot, with specific praise for individual account managers

• Reliable Billing: Monthly billing based on AMR/Smart data minimises the catch-up bills that often plague businesses with larger suppliers

The Cons

• Expensive Deemed Rates: Like most commercial suppliers, if you are out of contract, your unit rates will rise sharply—often exceeding 40p/kWh for electricity

• Business Hours Support: Customer service is strictly Monday to Friday (8:30 am – 5:00 pm), which may not suit businesses that operate primarily on weekends or late nights

• No Domestic Supply: You cannot bundle your home and business energy with Corona, as they are strictly a commercial provider

Customer Consensus: What Businesses Say

The general consensus is that Corona Energy is one of the most organised and professional suppliers in the market.

• The Positive: Many long-term customers highlight the personal touch, often mentioning specific staff by name. The ease of using the myCorona portal for tax returns and audits is a frequently cited benefit

• The Negative: Most complaints center on the Deemed rate pricing for businesses that accidentally let their contracts lapse. Some larger users have also noted that pass-through costs can be complex to understand without an adviser's help
