What Type of Consumer Unit Do You Need?
The right consumer unit depends on the number of circuits required, the load characteristics, and the future expansion of the installation. Modern properties often demand space for lighting, socket circuits, kitchen appliances, EV chargers, heat pumps and outdoor supplies.
Popular Consumer Unit Sizes
- 4 Way: Small properties, outbuildings or minimal-load layouts – explore 4 way consumer units.
- 6 Way: Standard domestic rewires – see our 6 way consumer units.
- 8 Way: Ideal for modern homes and extensions – browse 8 way consumer units.
- Metal Boards: Required for most domestic installs under BS 7671 – view our metal consumer units.
RCD, RCBO & Surge Protection Options
Our boards support various protection styles depending on the design brief:
- RCD Split Load: Traditional dual-RCD format
- RCBO-Ready: Full circuit independence
- SPD-Ready: Surge protection built-in for 18th Edition compliance
EV & Heat Pump Compatible Units
Many of our consumer units are engineered for modern inverter-driven equipment such as electric vehicle chargers and heat pumps. These units provide the correct RCD/RCBO pairing and allow straightforward integration of surge protection and PME fault-disconnection solutions.
Choosing a Future-Proof Board
When selecting a consumer unit, it’s advisable to allow headroom for additional circuits and future upgrades. EV chargers, outdoor supplies, loft conversions and kitchen renovations can all require extra ways, making 6–8 way units the preferred choice for new installs.
