Corona Energy Business: Electricity & Gas Tariffs & Reviews 

Corona Energy is one of the only British energy suppliers selling almost exclusively to business. The green energy provider has also been in business since the 1999. Today, it supplies 13,000 business customers and 85,000 meters across the U.K. 

 While Corona Energy is primarily a green energy buyer, it’s also working on green energy production of its own. Additionally, Corona Energy does not offer residential power or electric. That means the business stays small and specialized. This makes it a perfect fit for microbusinesses and industries that need business electric and good customer service. Otherwise, Corona Energy is extremely popular with customers. It also receives high ratings across the web.  

Corona Energy Business Electricity Tariffs 

Corona Energy offers both variable and fixed rates, with standard and half-hourly meter rates available. However, Corona Energy is not upfront about pricing, Instead, you must contact them for a custom quote to start a contract. This means it’s important to compare pricing to ensure you’re getting a fair deal.  

Corona business energy tariffs offer:  

  • 100% renewable energy 
  • 12-36-month contracts  
  • Exit and early termination fees apply  
  • Out of contract rates are 22.50p per kWh with a 0.90-700p daily standing charge  
  • Deemed rates are 22.50p per kWh with a 0.90 (non-half-hourly meter) to 700p (half-hourly meter) daily standing charge  
  • Dedicated account managers 
  • Automatic Meter Reading available  
  • 10-day setup time for new contracts 

While Corona Energy doesn’t offer transparent pricing, the company does offer fully custom quotes to every customer. That means pricing and offerings are fully scaled to your business.

That means you get green gas, and nothing is carbon offset. 

When you do request a quote, make sure you have your full business information ready. If you spend more than £11,000 a year, you’ll have to call to make custom arrangements. In most cases, you’ll get the fastest result if you call upfront anyway. For example, Corona Energy attempts to answer all email requests within 48 hours. However, they will likely request additional information in response to your email.  

Corona Energy Business Gas Tariffs & Plans 

Corona Energy is one of the only energy suppliers in the UK to deliver 100% green gas. Additionally, Corona is OFGEM certified for biogas. In fact, they use 100% biogas produced in the U.K. This means that for every kWh of gas you use, a kWh of green gas goes onto the grid. That makes Corona Energy a top choice if you’re concerned about the environment. Additionally, if going green is a key part of your business’s social responsibility platform Corona is a good choice.

Commercial Energy Billing Process 

Corona Energy sends a monthly invoice to your online portal and to your postbox. This includes VAT, AMR rates, and non-tariff rates such as the Climate Change Levy (CCL). Additionally, you’ll have multiple options to pay. However, Corona Energy handles most payment and invoice data through its portal. 

Change of Tenancy

  • Find proof of the move. This can include a lease agreement or certified tenancy agreement. You can also use a solicitor’s letter with details of the move, or a deed of surrender signed by both parties. Additionally, you can choose a TR1

Submitting Meter Readings  

Corona Energy heavily invests in Automatic Meter Readings and in Smart Meters. However, if you have neither, you’ll still have to submit a meter reading. You can do so online or by calling 0800 804 8589.  

Additionally, if you have more than 10 meters, you can submit your readings using an Excel sheet. Use the instructions here to format and upload your spreadsheet. You can also log into the MyCorona web portal to submit your meter reading.  

Importantly, it’s much faster to submit via the MyCorona portal. The submission number goes to general customer service, meaning you’ll have to select through to reading submission. From there, you’ll still have to submit MPAN numbers for every meter you’re submitting.  

Smart Meters 

Corona Energy is rolling out smart meters on a zip code basis. This means that when your area qualifies for meter installation, they will contact you. Otherwise, there is no signup process and no way to tell Corona Energy you’re interested.  

Smart Meters allow you to skip meter reading submission. It also means you’ll get more accurate bills, especially if you’re paying variable rates. Why? Smart meters track and upload energy usage in real time. Therefore, you’ll always know what you’re using and when. This allows you to make smarter decisions around energy usage.
