Are you wondering who your DNO is? Read on and find out how to find your DNO (Distribution Network Operator) in the UK if you are thinking of connecting an energy device like Solar Panels to the National Grid.
What is a DNO?
DNO is short for Distribution Network Operator. DNOs are companies that have the license to deliver electricity from the National Grid to your home or business. The UK has 14 different district networks or DNO regions, which are owned by 6 groups:
- Electricity North West Limited (ENWL)
- Northern Powergrid
- Scottish and Southern Energy (SEE)
- ScottishPower Energy Networks (SPEN)
- UK Power Networks (UKPN)
- Western Power Distribution (WPD)
Finding your DNO
To identify your DNO you’ll need the relevant first two digits shown as part of your MPAN (Meter Point Administration Number).
Your MPAN is the unique identifying number for the electricity meter at your property, often referred to as a ‘Supply Number’ or ‘S’ number. This number is made up of 13 digits highlighted in the bottom row of the illustration below.
For example, the ‘10’ in the bottom row corresponds with the Distribution ID for UK Power Networks in the look-up table below. The MPAN will be shown on any bills you have, and may also appear on a recent letter or email that your energy company has sent you.

FAQ DNO (Distribution Network Operator)
A DNO stands for Distribution Network Operator. These are the companies responsible for delivering electricity from the National Grid to your home or business in the UK. There are 14 different DNO regions across the country.
You can find your DNO by looking at your Meter Point Administration Number (MPAN). This unique 13-digit number identifies your electricity meter and can be found on your electricity bills or recent communications from your energy supplier.
The first two digits of your MPAN correspond to your specific DNO region.
While the MPAN is the most reliable way, some resources offer a postcode lookup to potentially identify your DNO. However, this method might not be as accurate.
Knowing your DNO can be helpful in situations like:
Power cuts: You can find your DNO’s emergency contact number in case of a power outage.
Installing solar panels: Some DNO applications might be required for solar panel installation.
