Meters and meter readings

Browse our answers for meter readings explained, how to work out gas meter readings, and help with understanding electricity meter readings.

Reading your meter

Find out here why it's better to provide us with regular, accurate readings than to rely on estimates.

For a start, it keeps your bills up to date, and helps you avoid energy debt.
You'll also find meter readings explained in full. Our clear illustrations of the different kinds of meter display will show you how to work out gas meter readings and read the dials on your electricity meter. We also explain how to give us your meter readings, whether you're doing it through My OVO, by using the OVO app or by giving us a call or email.


Giving us meter readings when you're moving home or switching supplier

The most important readings are your opening and closing meter readings. If they're wrong you could end up paying for someone else's energy. That's why understanding electricity meter readings, and gas ones is important.

Sometimes when we get a customer's opening or closing meter readings, they're not what we (or they) were expecting. We tell you here how to query these readings, and what to do if you think your opening meter reading is wrong.

When you join OVO, we'll also ask for the MPAN and MPRN numbers from your meters. These are unique numbers we use to ensure we take over your home's supply and not someone else's.
