Corona Energy offer the option of an ‘SME Fully Fixed’ product and an ‘SME Fixed’ productThese product names can be confusing given their similarity however there are fundamental differences between the two.SME Fully Fixed adopts a policy of fully fixing all elements contained within their fixed contracts; this includes all third party charges*. This is a market leading position and means that when you agree an SME Fully Fixed contract with Corona Energy you are safe in the knowledge that the price will remain at the level agreed throughout the contract.

SME Fully Fixed

CommodityInclusive, Fixed Transportation: Inclusive, Fixed MeteringInclusive, Fixed FITInclusive, Fixed (Electricity only) ROInclusive, Fixed (Electricity only) CFDExcluded, Fixed (Electricity only)

In contrast SME Fixed adopts a policy of fixing only the energy (commodity) element of the price. This means that when you agree an SME Fixed contract with Corona Energy the price can change through the contract term to reflect additional costs.

SME Fixed

CommodityInclusive, Fixed Transportation: Inclusive, Variable MeteringInclusive, Variable FITInclusive, Variable (Electricity only) ROInclusive, Variable (Electricity only) CFDExcluded, Variable (Electricity only)

*Corona Energy’s contracts however do not contain CFD regardless of the contract option. This is charged on top of the agreed contract rates.Corona Energy also reserves the right to amend the terms of their contract in exceptional circumstances.These include:
  • Where a change in law occurs affecting delivery of the contract.
  • Where the customer fails to fulfil their obligations under the contract.
  • Where gas customers fail to use the stated consumption under the terms of the contract.
  • Where the installed metering system changes.

Back billing and Corona Energy

Corona Energy is signed up to the Energy UK Back Billing standards. Corona limits its maximum period for back billing to between four and five years for gas and three years for electricity.Many suppliers have voluntarily limited their back billing rights to two years and in some cases a single yearHowever equally a number of suppliers are not signed up to the Energy UK Back Billing standards and therefore, under the Limitations Act, are able to back bill their customers for anything up to 6 years.Corona Energy are therefore one of the less amenable suppliers in this area making a smart meter a sensible choice with Corona.To find out more visit our Guide to Back billing.

Corona Energy and Letters of Authority

In order to act on your behalf in securing your business a great energy deal Corona Energy require us to have a signed Letter of Authority from yourselves.

Change of Tenancy and Corona Energy

Moving into a premise is known as a Change of Tenancy in the business energy market. It has also been termed a Change of Occupier or is known by its acronyms CoT and COO. However it is referred to, the opportunities it opens up are the same.This is great news for deal seekers. Whilst the existing supplier is obliged to continue to provide energy to the new occupier, the occupier is not obliged to take out an extended contract with that supplier.Indeed a Change of Tenancy customer has total freedom of movement and is free to accept a contract with a supplier of their choiceThere are however of course a number of rules and requirements.Firstly, as the new occupier, if you use energy you will need to pay for it, regardless of your contractual status.Secondly, you will need to identify as quickly as possible the identity of the existing supplierThirdly, you will need to field calls from sales organisations and the existing supplier themselves offering you contracts of varying lengths to continue or to begin to supply the premises.As a result as a new occupier you will need to agree a new contract either with the existing supplier or with a new supplier of your choice.Not only that but you will need to inform the existing supplier as quickly as possible that you are the new tenant to prevent you being held liable for charges incurred by the previous occupier should they not have ended their agreement satisfactory.It can prove a real headache knowing whom to trust – whether it’s the old tenant, the landlord the current supplier, the pushy salesman ringing, knocking and emailing, the prospective new suppliers.That’s where Business Juice comes in, by working on your behalf, identifying your existing supply arrangements, reporting your change of tenancy, ensuring you are not held liable for costs not incurred before your occupation and benchmarking contracts for your selection we can help you save time, money and a whole lot of stress.


Corona Energy sends their renewal letter to customers around 90 days in advance of the contract end date. This will contain Corona Energy‘s proposal for your rates for the coming period. It may provide a variety of options or a single price. It will however not be the most competitive price available in the market as the renewal letter is designed for customers who don’t use an energy broker and as such are priced at a higher level than can be obtained in the market.If you have a Corona Energy invoice and are in doubt feel free to fax us your bill on 0845 387 5701 or send it to and we will help.
