How to change your kVA with your DNO
To change your kVA (either increase or decrease) you need to contact your DNO with the following information:
MPAN* | Site Address | Current ASC (kVA) | New ASC (kVA) |
---|---|---|---|
1023456789012 | 1 Example road | 1200 | 1080 |
*This can be found on your supply bill and is sometimes referred to as an SPAN number.
It may appear like this on your supply bill. The MPAN number is the 13 digit number along the bottom line.

The DNO you contact will vary depending on the MPAN you want to contact them about. You can find the full list below. Use the first 2 digits of your MPAN to establish which DNO:
