From Supplier to Safe Disconnect

The Process Step by Step

Every electricity disconnection follows a clear, auditable sequence. Here is exactly what happens at each stage.

1

Metered Supply Disconnection

Disconnecting a metered electricity supply involves three separate parties and cannot be completed by the DNO alone. The supplier must close the account and arrange meter operator attendance for meter removal. Only once the meter is removed can the DNO carry out the physical disconnection at the cut-out. USP manages this three-party process as a single coordinated programme, removing the risk of one party being ready before another and causing programme delays.

2

Substation Decommissioning

Decommissioning a high voltage substation requires DNO authorised HV de-energisation as the first step. This is a non-contestable activity that must be carried out by the DNO itself. Once HV de-energisation is confirmed, USP terminates the LV cable connections, coordinates the removal of the substation structure, and manages all asset management authorisation paperwork. The DNO network records are updated on completion to reflect the decommissioned asset.

3

Cable Removal and Abandonment

Once de-energisation is confirmed, cables may be proved dead using approved instruments in accordance with NGED safe working procedures, sealed or removed under a permit-to-dig system. USP operates a formal permit system on all sites to ensure no cable cutting or excavation takes place until every conductor has been proved dead. Cables that cannot be removed (due to depth or ground conditions) are sealed at both ends and recorded on as-built drawings.

4

Pre-Demolition Clearance

Full pre-demolition clearance covers all electrical services on site, not just the main metered supply. This includes street lighting, traffic signals, external power supplies, telecoms ducting, unmetered equipment, and any temporary or permanent supplies associated with the building or site. USP carries out a pre-demolition survey to identify every electrical service, confirms its disconnection, and provides written confirmation for the Principal Contractor's CDM health and safety file.

Key Technical Considerations

Technical Specifications

The critical parameters that govern every electricity disconnection and supply removal project.

Metered disconnection
Three-party process: supplier account closure, meter operator removal, DNO physical disconnection at cut-out. USP manages all three.
Substation decommissioning
DNO authorised HV de-energisation required as a non-contestable first step before any contestable works begin.
Cable proving
All conductors proved dead using approved instruments in accordance with NGED safe working procedures before excavation or cutting.
Temporary supply removal
Coordinated with permanent energisation where applicable. Temporary supply remains live until permanent supply is ready.
Pre-demolition survey
Identifies all electrical services on site including unmetered, street lighting, traffic signals, and external power supplies.
CDM documentation
Written disconnection confirmation issued to Principal Contractor for inclusion in the health and safety file.

Electricity Disconnections FAQs

Frequently Asked Questions

Electricity disconnection is a three-party process. The supplier closes the account and coordinates with the meter operator for meter removal. The DNO (Distribution Network Operator) then carries out the physical disconnection at the cut-out or service fuse. USP manages all three parties as a single coordinated process under one contract.
Substation decommissioning requires DNO authorised HV de-energisation before any contestable works can begin. Once HV de-energisation is confirmed, USP terminates the LV cables, coordinates structure removal, and manages all asset management authorisation. The DNO updates its network records on completion.
All cable proving must be carried out using approved instruments in accordance with the DNO safe working procedures before any excavation or cable cutting takes place. USP cable proves every conductor on site before work begins and maintains a permit-to-dig system throughout the project.
Yes. Temporary builder's supplies are removed as part of the wider disconnection programme, coordinated with the transition to permanent energisation where applicable. USP manages the timing so the temporary supply remains live until the permanent supply is ready.
Pre-demolition clearance must cover all electrical services, not just metered supplies. This includes street lighting, traffic signals, external power supplies, and any other unmetered equipment. USP carries out a pre-demolition survey to identify all electrical services and confirms their disconnection in writing for the CDM health and safety file.
