Most meters, whether that is electric or gas, are found on the ground floor of the property. This is the point where energy enters the property. They may be found under the stairs, located in the hallway, kitchen, or even in a cupboard.
Meters may also be found on the outside of your property, located in a box that is built into the outside walls. If you live in an apartment block, they are likely in the basement.
If you are unsure on where to find your meters, ask your landlord or letting agent who will be able to help you locate them.
