Transformer and Substation Decommissioning

The full decommissioning workflow

Decommissioning a transformer or substation is a sequence, not a single task. It begins with a survey and a clear scope, followed by electrical isolation, make-safe works, drainage of oils where required, disconnection, removal and finally compliant disposal or recycling.

We manage the whole workflow under one Risk Assessment and Method Statement, so responsibility and documentation are clear from start to finish.

Isolation and make-safe

Safe isolation is the foundation of every decommissioning job. Equipment is proven dead and made safe before any intrusive work, with permits to work and lock-off procedures in place. This protects both our teams and your live infrastructure.

Make-safe works ensure the area is left in a controlled, hazard-free condition at each stage of the programme.

Working with your M&E contractor — or self-delivering

We can work alongside your existing M&E contractor, picking up the heavy-removal and disposal elements while they handle electrical works — or we can self-deliver the entire scope including isolation through our network. Either model is supported, depending on what suits your project.

This flexibility makes us straightforward to integrate into a wider refurbishment, demolition or estate programme.

Multi-site rolling programmes

For utilities, estates and portfolio owners, we deliver rolling decommissioning programmes across multiple sites under a single agreement. The same teams, RAMS process and documentation apply at every location, giving you consistency and a clean audit trail across the whole programme.
