Our rates

The price you pay for your energy with us will depend on what type of contract we currently have in place with you.

Fixed Term Contracts

The price you pay for your energy is fixed at the start of your contract. All prices are subject to VAT, CCL and include third party charges required to provide your energy supply.  These charges could be subject to change which may be passed through. To fix the cost for your energy, Opus Energy will purchase upfront the energy needed for your contract period. For this reason, if you attempt to switch suppliers during the fixed term period we may object to the transfer.

If you are a new customer who has recently transferred to us, or an existing customer who has renegotiated a new contract, you are likely to be on a Fixed Term contract.

Where can I find out what price I am paying?

When you agreed your contract with us, we wrote to you confirming your prices and the details of your contract. Your prices are also detailed on your monthly bill. You can log onto your account online, or contact our Customer Service team on 0843 227 2377 who will be happy to help.

You can also find more information about your bill.

What happens when my fixed term ends?

We will write to you to let you know that the end of your fixed term is approaching; this letter will include details of your current price, as well as what happens at the end of your fixed term. If you choose not to negotiate a new contract with us, but remain supplied by us after your fixed term has ended, your account will move onto a Variable rate and these prices are also detailed on this letter. If you are on a Variable rate, you can renegotiate a new contract at any time by calling 01604497154.

How can I find out what my Variable rate is or is going to be?

If your fixed term period has ended and you have moved onto a Variable rate, your prices will be detailed on your bill. You can also log into your account online.  If your fixed term has not yet ended, but we have sent you a letter to let you know the end is approaching, your rates will be on that letter.  If you don’t have any of the above paperwork, please contact our Customer Service team to discuss your variable rate.

Deemed contracts

If you have recently moved into a property where Opus Energy supply the gas or electricity and you have not agreed a Fixed Term contract, then you are deemed to have entered into an agreement with us as the supplier to the property. This means that we have to supply your new property with gas or electricity and you are required to pay for that fuel at our published deemed rates.  Deemed rates are likely to be higher than Fixed Term contract rates. If you would like to benefit from a lower rate, our Sales team can offer you a new contract with a competitive tariff which can be fixed for up to 3 years.  If you would like to discuss your options, please call us on 01604497154.

If you have not told us yet that you have moved into a property supplied by Opus Energy, it’s important you do so that we can set your account up correctly. You can find how to do that here. Once we have the account setup in your organisation’s name, we will write to you to provide you with your current Deemed rates. Alternatively, you can find these rates below.

Current Deemed Rates - Electricity:

Deemed rates are calculated based on the first two numbers of the top line of your supply number – this can be found on your bill.

Current Deemed Rates – Gas:

Deemed rates for gas are calculated based on consumption bandings which are calculated using the amount of gas a site uses over a period of 12 months. If you know which consumption banding your property fits into, you can use the table below to look up the rates. If you do not know please contact us and we will be able to provide you with the information and the rates.
