Back billing and Opus Energy

Opus Energy is signed up to the Energy UK Back Billing standards and currently limits back billing to one year for all SMEs including micro business.This is a market leading position.Many suppliers have voluntarily limited their back billing rights to two years and in some cases a single year.However 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.Opus Energy are therefore the clear leader of the stronger suppliers in this area.To find out more visit our Guide to Back billing.

Change of Tenancy and Opus 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.

Your Opus Energy Invoice places the contract end date on the rear of the first page of the invoice, this is in the section entitled  “Contract Details”.

This will contain Opus’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.

Rollover contracts and Opus Energy

For Opus Energy customers on their variable ‘rollover’ option:Now, when as a Opus Energy variable rollover customer, your contract comes to an end, even if you have not contacted Opus energy or have not accepted their renewal offers you will simply be placed on their ‘”Variable Price Plan”.The “Variable Price Plan” will be more expensive than a “Fixed Price Plan” but it will allow you to leave within 30 days of giving notice.Of course it makes sense not to get to this point in the first place and so contracting well in advance is always recommended as even a short term stay on a “Variable Price Plan” will be significantly more expensive than other options. At least however you can be safe in the knowledge that if you do make a mistake and fail to contract properly the cost of your error can be minimised.However by using Business Juice you can avoid the potentially costly mistake of being exposed to variable rates.

For Opus Energy customers on their fixed ‘rollover’ option:

Now, when as a Opus Energy fixed rollover customer, your contract comes to an end, even if you have not contacted Opus energy or have not accepted their renewal offers you will be rolled over for a fixed term of 12 months.By using Business Juice you can avoid the costly mistake of falling into the rollover trap and paying premium rates for 12 months.To find out more about rollovers visit our Guide to Rollover Contracts.
