Metal Consumer Units for Domestic, Commercial & EV Installations
Metal consumer units are the standard choice for many modern installations, giving electricians a durable steel enclosure, tidy circuit layout, and a practical board format for rewires, upgrades, new builds, and specialist supplies. This range includes boards for domestic, commercial, and EV-related installs, with options covering both traditional twin RCD layouts and more specialist protection arrangements.
Whether you're replacing an older board, specifying a new metal unit for a house rewire, or looking for a board with integrated protection features, this collection is built around trade-ready, install-focused options.
Quick answer: A metal consumer unit is a steel-enclosed distribution board used to house circuit protection devices such as MCBs, RCDs, and RCBOs. They are widely used for domestic and commercial installs where a more robust enclosure and modern board layout are required.

Why Choose a Metal Consumer Unit?
A metal consumer unit gives installers a more robust board enclosure for modern circuit protection layouts. Compared with older plastic styles, metal boards are widely specified for rewires, upgrades, and new installations where durability, tidy cable management, and a clean internal layout all matter.
What Is a Metal Consumer Unit?
A metal consumer unit is a distribution board housed in a steel enclosure, designed to contain and organise protective devices such as MCBs, RCDs, and RCBOs. They are used across domestic and commercial environments to distribute power safely across multiple circuits.
Common Types of Metal Consumer Unit
- Twin RCD consumer units – a common choice for traditional domestic circuit grouping
- RCBO-ready boards – suited to installations where individual circuit protection is preferred
- PME fault detection boards – used for relevant EV and outdoor equipment applications
- Larger multi-way boards – for commercial, extension-heavy, or higher-demand installs
Typical Applications
- Domestic rewires – replacing older boards with a modern metal consumer unit
- New builds and extensions – where extra circuit capacity is needed from the start
- Commercial installations – where larger layouts or more robust board formats are required
- EV-related installs – where additional protection arrangements may need to be built into the board selection
Twin RCD Metal Consumer Units
Twin RCD metal consumer units remain a popular choice for standard domestic layouts. They allow circuits to be split across two RCDs, giving a familiar and cost-effective board format for many homes, extensions, and general upgrade projects.
Metal Boards with PME Fault Detection
Some metal boards are designed around PME fault detection, which is relevant on certain EV charger and outdoor electrical installations connected to a TN-C-S supply. These products sit closer to specialist application boards than standard domestic consumer units.
Choosing the Right Size Metal Consumer Unit
The right board size depends on how many circuits the property needs now, plus any allowance for future additions. Smaller homes may suit more compact boards, while larger properties, extensions, and mixed-use installs often benefit from a board with extra outgoing ways from day one.
Used Alongside RCBOs, RCDs & Circuit Protection
Metal consumer units are commonly specified alongside RCBOs, RCDs, MCBs, and wider circuit protection products. For more specialist setups, see our PME fault detection and EV consumer unit ranges.
FAQs on Metal Consumer Units
What is a metal consumer unit?
A metal consumer unit is a steel-enclosed distribution board used to house circuit protection devices and distribute power across multiple circuits in a property or installation.
Are metal consumer units used for domestic installs?
Yes. Metal consumer units are widely used on domestic rewires, board changes, extensions, and new build installations.
What’s the difference between a twin RCD board and an RCBO board?
A twin RCD board groups circuits across two RCDs, while an RCBO-based board allows individual circuit protection. The right choice depends on the installation design and protection strategy.
Can a metal consumer unit be used for EV installs?
Yes, where the board and protective arrangement are suitable. Some products in this range include more specialist options relevant to EV and outdoor supply installations.
