MPAN & Postcode Lookup
Who Is My Electricity DNO, Water & Gas Network? (UK Lookup)
Enter your UK postcode to find your electricity DNO (105 fault number), MPAN code, water company, gas distributor (0800 111 999) and live outages.
Identify Your DNO from Your Electricity Bill (MPAN Number)
On any UK electricity bill, find the boxed "S" grid labelled Supply Number (MPAN). The top-left two-digit Distributor ID (10–23 in Great Britain, 32 in NI) identifies which physical DNO owns your local cables and repairs power cuts — regardless of which energy retailer you pay.
