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.
