Galldris safer charging at Sizewell C: fire and trip-risk lessons for site teams
Reviewed by Tom Sullivan

30 Second Briefing
Galldris has deployed an Armorgard VoltHub lithium-ion charging station at Sizewell C to replace ad hoc charging of power-tool batteries in canteens and offices, which had created trailing-cable trip hazards and uncontrolled battery fire risk. The VoltHub unit provides enclosed, centralised charging with direct connection to the site fire alarm system and is selected ahead of incoming Class-L fire-safety standards. Health and safety manager Julian Beard, drawing on previous use in Hinkley Point C intake tunnels, reports reduced equipment damage and loss, and clearer welfare areas free of chargers and cables.
Technical Brief
- Armorgard’s flagship VoltHub was selected specifically to meet forthcoming Class-L lithium fire-safety requirements.
- Direct linkage of VoltHub to the Sizewell C site-wide fire alarm enables immediate centralised incident response.
- Galldris’ previous arrangement was deemed a “major compliance issue” by its internal health and safety team.
- Selection followed a Sizewell C-led safety forum, indicating principal contractor oversight of subcontractor battery-charging controls.
- Health and Safety Manager Julian Beard had already deployed VoltHub in Hinkley Point C intake tunnels, providing nuclear-sector precedent.
- Centralised charging has shifted equipment stewardship to individual operatives, reducing uncontrolled communal storage and loss.
Our Take
Sizewell C already features in our database for complex marine and tunnelling works led by Amentum, so Galldris’ adoption of controlled lithium‑ion charging around intake tunnels fits a pattern of contractors tightening risk management on constrained underground and nearshore work fronts.
Among recent UK Infrastructure safety‑tagged pieces, lithium‑ion appears only rarely as a named keyword, suggesting that formalised battery‑charging controls on major sites like Sizewell C and Hinkley Point C are still at an early adoption stage rather than standard practice.
With Heidelberg Materials UK installing a nuclear‑grade batching plant at Sizewell C, the move by Galldris to use dedicated VoltHub stations indicates that both materials and temporary works suppliers are being pushed towards nuclear‑style quality and safety regimes even for ancillary equipment and site logistics.
