Who is my DNO?
Your DNO is the distribution network operator that owns and runs the local electricity network where your property is. It looks after the poles, cables and substations, deals with power cuts and builds new connections. It is not the company you pay your electricity bill to. That is your supplier.
Find your DNO from your postcode
This is based on your postcode area, so it is a good guide but not a guarantee. Network boundaries do not follow postcodes, and a few properties near a border are served by the next operator. Confirm it with the check below before relying on it.
Confirm your DNO from your MPAN
Your electricity bill shows a Meter Point Administration Number (MPAN). The top line of the MPAN has a two digit distributor ID, which identifies your DNO area:
- 10 Eastern (UK Power Networks)
- 11 East Midlands (National Grid)
- 12 London (UK Power Networks)
- 13 Merseyside and North Wales (SP Energy Networks)
- 14 West Midlands (National Grid)
- 15 North East (Northern Powergrid)
- 16 North West (Electricity North West)
- 17 North of Scotland (SSEN)
- 18 South of Scotland (SP Energy Networks)
- 19 South East (UK Power Networks)
- 20 Southern (SSEN)
- 21 South Wales (National Grid)
- 22 South West (National Grid)
- 23 Yorkshire (Northern Powergrid)
Northern Ireland is served by NIE Networks. A small number of sites are connected to a private network run by an independent network operator (IDNO) instead.
Why you might need to know
- To report or ask about a power cut. You can call 105 free from anywhere in Great Britain and it connects you to your DNO.
- To get a quote for a new electricity connection, or to increase your supply for a heat pump or EV charger.
- To apply for a solar or battery connection.
The free GridQuotes tool finds your DNO from your address and gives a budget price for a new connection from its published charges.
Frequently asked questions
Who is my DNO?
Your DNO is the distribution network operator that owns the local electricity network at your property. Enter your postcode above to see the most likely one, then confirm it with the distributor ID on your MPAN.
Is my DNO the same as my electricity supplier?
No. Your supplier sells you electricity and sends the bill. The DNO owns and maintains the local wires, poles and substations, and you cannot choose it.
Can I change my DNO?
No. It is set by where the property is. You can change your supplier, but not the DNO.
How do I contact my DNO about a power cut?
Call 105. It is free and connects you to the network operator for your area.
Who is my DNO for a new connection?
It is the DNO for the property's location. They quote for a new connection, or an independent connection provider can quote for part of the work.
