DNO Decommissioning Process for Renewable Energy Systems in the UK
When removing or decommissioning a renewable energy system (such as solar PV, battery storage, wind turbines, or CHP), you must notify the Distribution Network Operator (DNO). This ensures that the disconnection is safely processed, avoids grid supply issues, and updates the national generation records.
What is a DNO Decommissioning Notification?
A DNO decommissioning notification is required when:
Completely removing a renewable generation system from the property
Upgrading or replacing generation equipment where the original system is removed
Disconnecting a system from the grid permanently
Decommissioning battery storage, solar PV, or wind turbines
The DNO must be informed to update grid records and ensure the safe disconnection of your system.
What’s Required for a DNO Decommissioning Notification?
Installer & Customer Details
Company name & accreditation (MCS, NICEIC, or approved contractor)
Installer and customer contact details
Site address and MPAN (Meter Point Administration Number)
System & Connection Details
Type of system being decommissioned (solar PV, wind, CHP, battery storage)
Total capacity (kW or MW)
Inverter manufacturer, model, and serial numbers
Connection type (single-phase, three-phase, HV/LV)
Export capacity before disconnection
Technical Documentation
Final system status report (confirmation of safe disconnection)
Electrical disconnection certificate

DNO decommissioning notification form
Application Submission & Process
Decommissioning notifications must be submitted to the DNO after removal
A formal disconnection request may be required if grid connection needs modification
There may be costs associated with disconnecting or modifying the supply
DNO processing time: Typically 30 days
What Happens Next?
Once submitted, the DNO will:
Acknowledge receipt of the decommissioning request
Update their records to remove the system from the grid registry
Issue confirmation once the system is fully decommissioned
Advise on any network modifications if required
