Your meter setup can be a complex beast of many parts all owned and maintained by different people. So we’ve put together this handy guide to help you figure things out and know who to contact in case something goes wrong or you’re looking to do some home improvements!

Electricity

Example of electricity meter setup:

Parts maintained by your Distribution Network Operator (DNO) 

• Meter tails before the cutout
• Meter backboard (although technically part of your property your DNO can help replace this)
• Cut-out (also known as 'service head'), which holds the main fuse - Its purpose is to absorb any energy surges which could damage the wiring and appliances within the property

You should contact the DNO in the event of:

• Loss of power which is affecting your neighbours too
• Emergencies or repairs required to your main fuse or main service cable
• Meter relocations beyond the current meter back-board, (check out more on that here).

To find out who your DNO is, check out this handy topic below:

Parts belonging to your energy supplier (that could be us!)

• Meter (traditional or smart) - this records the electricity consumption of all electrical items in the property
• Meter tails between cut-out to meter and between meter and isolation switch - they carry current between pieces of equipment

You will need to book an engineers visit with OVO:
