What Is a Metal Consumer Unit?
A metal consumer unit is a distribution board housed within a steel enclosure for improved fire resistance and safety. Metal boards replaced plastic units as the default choice, providing better containment and enhanced durability on site.
Why Installers Choose Metal Boards
- Fire-resistant steel enclosure designed for safer installations
- Rigid construction that survives handling, transport, and on-site conditions
- Ample wiring room for neat routing, reduced stress and easier inspection
- High compatibility with modern RCBOs, MCBs and surge devices
- Long-term durability ideal for both domestic and commercial premises
Twin-RCD Metal Consumer Units
Twin-RCD boards remain a popular choice for traditional domestic layouts. They allow circuits to be grouped across two RCDs, providing a balance of protection and affordability. These boards are suitable for lighting, sockets, kitchen circuits, showers and small extensions.
PME Fault Detection Metal Boards
PME fault detection units provide additional protection for installations connected to a TN-C-S earthing system, commonly required for EV chargers and outdoor electrical equipment. These models automatically monitor supply conditions and disconnect the load if a dangerous PEN fault is detected.
What Size Metal Consumer Unit Do You Need?
Choosing the correct way count depends on how many circuits the property requires, plus any future expansion:
- 8–12 way boards suit standard domestic rewires
- 14–18 way boards support larger homes or heavy appliance clustering
- 20+ way units are used in commercial, workshop or extension-heavy installations
Compliance & Standards
All metal consumer units in this category comply with BS 7671 (18th Edition) and meet the enclosure requirements set out in Regulation 421.1.201. Internal layouts are designed to support modern protective devices, clear labelling and easy periodic testing.
Installer Benefits
Metal consumer units provide a long-term, site-proof solution that simplifies installation, testing and future circuit expansion. With robust construction and clean internal layouts, they remain the preferred choice for both domestic electricians and commercial contractors.
