The journey
From a region, or a single MPAN, to the full rate card
Browse a region without an MPAN, or look up one site directly, then drill into the full site-specific EDCM rate breakdown with multi-year context.
Start
Start by region, or by MPAN
No MPAN? Browse by DNO region and cohort to see every EHV site we hold and the spread of their rates. Have one? Switch to By MPAN and paste the 13-digit Core or 21-digit Full format, validated live before the lookup runs.
Identify
Decode and identify the site
The MPAN is decoded against all 14 DNO regions. We then check public network registers for operator name, connection voltage, indicative registered capacity and site address.

The problem
Finding EHV rates means digging through DNO annexes
EDCM sites have unique tariffs based on their network location and connection characteristics. DNOs publish these in sprawling Annex 2/6 documents - one per region, updated annually. When a client asks about their EHV charges, you need to know exactly where to look.
Without quick access to site-specific rates, you can't validate client bills, provide cost forecasts, or compare what they're paying against similar sites.
Find any EHV site tariff, by region
Pick a DNO region or search a single site and the tool returns the exact EDCM tariff line for a 22kV-plus connection, import or export, straight from the charging statement.
