Industrial Scaffolding

High Voltage Works Scaffolding

Scaffolding designed and erected around live and isolated HV equipment — planned to your DNO clearances, your permit regime, and your outage window.

Skilled & Certified Scaffolders

High voltage work leaves no room for error. Clearances from live conductors are non-negotiable, your outage window is often tight, and the wrong scaffold design can stop a job dead. We erect scaffolds around substations, switchgear, transformers and HV plant across Milton Keynes and the wider region — and we plan every job around your DNO rules and your permit-to-work before we bring a single fitting on site.

Our teams regularly work for DNOs, ICPs, I&Cs and major industrial operators. We understand the difference between live-side and isolated-side working, we know what a Safety from the System briefing actually requires on the ground, and we'll design the scaffold to support — not fight — your safe system of work.

What we handle:

  • HV-aware scaffold design with clearance-compliant geometry
  • Earth bonding and continuity where specified
  • Non-conductive scaffold boards and Layher timber decks where required
  • Works planned around DNO outage windows
  • Full permit-to-work integration
  • Site-specific method statements and risk assessments

When you need it

Typical scenarios where high voltage works scaffolding is the right call.

Substation maintenance and repair

Access for transformer maintenance, switchgear replacement, busbar works and insulator replacement in primary and secondary substations.

New HV connections

Scaffold support for ICP-installed new connections — transformers, switchboards and cable terminations — coordinated with outage programmes.

Decommissioning and replacement

Access and lifting support for the removal and replacement of obsolete HV plant, including oil-filled transformer change-outs.

Getting HV scaffolding right

HV scaffolding is less about the scaffold itself and more about the planning around it. A perfectly well-built scaffold in the wrong place — too close to a live conductor, across an earth path, or blocking an emergency exit route — is a failed job. We’ve been doing this long enough to know that the first site visit is where the risk is either designed out or designed in.

On a typical substation job we’ll walk the site with your authorised engineer, agree the clearance envelope for live equipment, identify the isolation boundaries, and design the scaffold to sit cleanly inside the safe working zone. If there’s no way to avoid work close to live plant, we’ll redesign the scaffold to work inside the tighter live clearances rather than relying on the outage to carry the risk.

Working with your outage programme

Outages cost money. A transformer out of service, even at low load, is a revenue hit — and the window for the scaffold to go up, the work to happen, and the scaffold to come down is often brutally tight. We preplan the erection sequence so that parts of the scaffold not affected by the live geometry can go up before the outage starts, and dismantling can begin as soon as the work is signed off. On larger jobs we’ll run a second crew for the final strip-out so we’re not the critical path back to energisation.

Ongoing framework work

A lot of our HV scaffolding is carried out under framework arrangements with DNOs and ICPs where we’re a known quantity on the system. If you’re running repeat HV works and you want a scaffold partner who already understands your safety rules, your permit format, and your outage booking process, get in touch — we’ll happily set up a framework conversation.

Frequently Asked Questions

Do you work around live HV equipment?
We plan every job to be carried out around isolated equipment wherever possible. Where the geometry means we have to work adjacent to live plant, we design to the clearances defined in your safety rules (typically HSG85 and your DNO's operational standard) and our scaffolders work under the site's Safety from the System regime with a nominated Senior Authorised Person.
Can you work within a DNO outage window?
Yes — that's a regular part of the work. We plan erection and dismantling to fit within an agreed outage, and we'll phase the scaffold so that non-critical sections can be built ahead of the outage to compress the live window.
Do you supply earth-bonded and non-conductive scaffolds?
We can specify earth bonding and continuity testing where the scheme calls for it, and we can supply Layher system or timber decks in place of metal decking where non-conductive surfaces are required. The spec comes out of the design review with your electrical engineer.
Who's your scaffold suitable for — DNOs, ICPs, or industrial sites?
All three. We work for DNOs under long-term framework relationships, for ICPs delivering new connections, and directly for industrial operators doing in-house HV maintenance. The approach is the same — scaffold designed around your safety rules, not the other way around.
Are you CHAS and SafeContractor accredited for HV sites?
Yes. We hold CHAS, SafeContractor and CITB accreditation, and NASC membership. Our scaffolders hold CISRS cards appropriate to their level and we carry full public and employer's liability insurance suitable for HV industrial work.
