Opus Energy has standard terms and conditions and as a customer, you are committed to a minimum fixed term period.  

The length of this period depends on the specific contract you agreed with Opus when you signed up. Opus will write to you 60 days before the end of your fixed term period and let you know your renewal options or how to cancel your contract. 

If you want to change suppliers at the end of your contract and you owe Opus money, they may object to the switch, so just keep this in mind. 

When you cancel your account, there are a few things you have to do. You need to: 

  1. Send Opus a meter reading  
  2. Contact Opus to confirm your account and payment details. This is so they can refund any credit if you are owed any money 
  3. Check if you have any outstanding amounts to pay and settle these debts 
  4. If you are closing your account because of a change of tenancy, make sure you double check that Opus has the correct transfer date and forwarding address

Opus Energy FAQs  

Below are some frequently asked questions from Opus customers or potential Opus customers.   

Who should I contact first in an emergency - my supplier or my distributor? 

If you think there is any safety risk, you should always contact your distributor. They can attend and make the supply safe to limit any risk to you or your staff. Remember to be careful and not touch anything that could give you an electric shock. 

Contact Opus after you've spoken to the distributor to let them know what is happening. In most cases, Opus can have someone out the same day. 

I believe something is wrong with my gas meter. What should I do? 

You should call the National Grid Emergency Service on 0800 111 999. If they decide the issue is on your side, they might switch your supply off so that a gas-safe engineer can fix the problem. You can find out more in our guide to the Gas Safe Register and at our blog - How to keep your business gas safe.
