Opus Energy Smart Meter

Smart meters are available to small and large businesses that are supplied by Opus Energy, with no added costs for installation.

Smart meters automatically record your usage and communicate it with your supplier, saving you time and making sure your bills are accurate.

To get one installed, Opus Energy customers can request one from customer services, or request one online. Data sent from your smart meter to your energy supplier is always protected. You can read more on Opus Energy’s website

Other Opus Energy Meters

You can submit meter readings to Opus Energy online through My Opus Energy. Request online access through their Customer Service team. Submitting a meter reading online is easy and only takes a few minutes.

Customers with a commercial gas supply have their consumption logged remotely using AMR (Automatic Meter Readings). This means bills are more accurate and access to the meter doesn’t have to be pre-arranged.

Opus Energy Bills

Bills from Opus Energy will come in the form of an invoice; there’s a guide to what they look like and how to understand them on their website.

If your business’ bill is higher than usual, it could be because meter readings haven’t been submitted often enough, new equipment has recently been installed, or a fixed contract has ended. Your invoice from Opus Energy will tell you if you’re paying out-of-contract rates.

When you’re set up with the My Opus Energy online account, you can access all of your invoices, submit meter readings and check your contract dates.

If your business’ bill is higher than usual, it could be because meter readings haven’t been submitted often enough, new equipment has recently been installed and it’s using a lot of power, or a fixed contract has ended.
