8 Way Consumer Units for Domestic & Light Commercial Installs

8 way consumer units provide a balanced layout for modern homes, extensions, garages and small commercial spaces. With enough capacity for dedicated circuits plus future expansion, they offer a practical mid-size solution that suits the majority of UK rewires and new installations.

An 8-way board offers space for lighting, socket circuits, kitchen appliances, EV chargers, heat pumps and outbuilding feeds, without the overcrowding or limitations of smaller units. Available in main-switch, dual-RCD or RCBO-ready formats, they support a wide range of installation designs under the 18th Edition. These boards form part of our wider Consumer Units range.

  • 8 usable ways – ideal for most domestic circuit layouts
  • Main switch, RCD or RCBO-ready formats depending on design preference
  • 18th Edition compliant for new installations and upgrades
  • Robust metal enclosures for improved fire resistance
  • Ample space for clean wiring and future additions

These boards are a popular choice for electricians who want a versatile, future-proof consumer unit that remains compact while still offering solid headroom for additional circuits.

Why Choose an 8 Way Consumer Unit?

An 8 way consumer unit offers a practical balance between size and capacity, making it suitable for small to medium-sized properties. It provides enough space to meet the needs of modern households while maintaining a manageable footprint for installation.

Common Uses

  • Full domestic rewires where 6–10 circuits are typical
  • Extensions or renovations requiring additional capacity
  • Outbuildings and workshops with multiple circuits
  • Small commercial units with mixed lighting and socket loads
  • Properties needing future expandability for EV chargers or heat pumps

Main Switch, RCD or RCBO Layouts

8 way boards are available in different configurations depending on the installation method:

  • Main Switch: Full RCBO design for maximum circuit independence
  • Dual RCD: Split-load protection with grouped circuits
  • RCBO Ready: Modern approach for EVs, heat pumps and inverter loads

Metal Enclosures for Safety

All units feature steel enclosures that meet the fire containment requirements of the 18th Edition. Internal design typically includes removable busbars, spacious terminal entries and clear labelling for a clean install.

Installer Benefits

With reliable build quality, ample wiring space and a familiar layout, 8 way consumer units make installation straightforward. They support tidy circuit separation, testing access and future upgrades without requiring a larger board.
