With over 20 years of service, Corona Energy has become one of the largest business energy providers across the UK. We break down everything you need to know about the company’s tariffs, reviews, online services and contact details.
About Corona Energy
Corona Energy is one of the country’s leading gas and electricity suppliers for businesses. Founded in 1995, the utility company was acquired by Australian financial company Macquarie Group in 2006.
Corona Energy provides energy to around 13,000 non-domestic customers and is responsible for more than 85,000 meters nationwide. Around three-fourths of the provider’s customer base is made up of micro businesses and small and medium-sized enterprises (SMEs), while industrial and commercial (I&C) accounts make up for the remaining quarter.
What are micro businesses?* Micro businesses employ fewer than 10 people and have an annual turnover of less than £2 million. They spend on average between £1,300 and £3,064 on electricity and gas per year.
Tariffs and prices
Corona Energy offers a range of flexible and fixed-rate tariffs to suit your individual business needs. The provider will customize your price based on the size of the business and its projected energy use. All gas and electricity bills are paid via a monthly direct debit.
Corona Energy’s fixed tariffs can protect your energy price for up to 36 months! The energy supplier also offers 100% renewable energy tariffs for businesses that are serious about going green.
Micro businesses can get a quote online in under two minutes on the Corona Energy website. If you have a larger business, you must contact the sales team for a quote by calling 0800 804 8589.
If you move into a premise that is supplied by Corona Energy but you do not agree to a contract, the provider will automatically put you on a deemed tariff (also called an ‘out of contract’ tariff). You will also be rolled onto a deemed tariff if your contract agreement expires and you do not contact Corona Energy and ask to be put on a new one.
The energy prices for deemed tariffs are always more expensive than fixed rates. Deemed energy rates are also subject to change, and Corona Energy is not obliged to give you notice. Let’s have a look at the current deemed rates for gas and electricity.
Business electricity prices differ depending on the type of meter you have. Half-hourly meters utilise automated meter reading (AMR) technology to send updated readings every half hour to Corona Energy. These meters are required for larger businesses.
|Meter type||Unit rate||Standing charge||Availability charge|
|Non-half-hourly meter||22.5p per kWh||£0.90 per day||£0.00 per kVA per day|
|Half-hourly meter||22.5p per kWh||£7.00 per day||£0.05 per kVA per day|
Business gas prices are divided into six bands. While the rate you pay per unit of gas does not vary depending on your energy usage, heavier users are charged a higher price per day just to be connected to the gas supply.
|Band||Estimated annual consumption||Unit rate||Standing charge|
|Band 1||Up to 73,200 kWh||5.90p per kWh||£3.00 per day|
|Band 2||73,200 - 300,000 kWh||5.90p per kWh||£6.00 per day|
|Band 3||300,000 - 750,000 kWh||5.90p per kWh||£9.00 per day|
|Band 4||750,000 - 1,450,000 kWh||5.90p per kWh||£15.50 per day|
|Band 5||1,450,000 - 3,000,000 kWh||5.90p per kWh||£25.00 per day|
|Band 6||More than 3,000,000||5.90p per kWh||Depends on site|
On the customer review site Trustpilot, Corona Energy received an average rating of just 2.2 out of five. The supplier received an even lower rating of 1.8 on Google Reviews. We took a look at Corona Energy reviews to see what business customers had to say about the energy provider.
Unfortunately, Corona Energy reviews seem to have taken a turn for the worse over the past year, with many reviews even saying the gas and electric company is “incompetent.” Customers have increasingly left negative reviews regarding inaccurate invoices from the provider, even when they submitted meter readings on time.
“Absolutely appalling service, I never struggled this much with energy bills.”
We also noticed a recurrence in reviews from non-customers who reported receiving electricity and gas bills, in addition to threatening letters from Corona Energy even though their energy supply was never with the company.
“Never supplied me energy yet incessant calling and hassling for a large sum of money. Simple issue to resolve yet they seem incapable. I feel sorry for those they do supply. Hopeless.”
It is important to consider that customers are more likely to leave a review when they are upset rather than when they are satisfied.
