If you’re considering upgrading your electrical installation, comparing Hager consumer units by range is a smart place to start. From entry-level setups to premium flush-mounted boards, Hager’s Design 10, 30, and 50 consumer units each cater to different project requirements. Whether you’re a homeowner, installer, or specifier, understanding the practical differences between these Hager board types helps you choose the right model—without compromise.
Understanding the Hager Design Series
Hager offers three main ranges of consumer units, each offering specific benefits in terms of layout, appearance, and installation flexibility. While the internal functionality remains consistent across the ranges, external design and included features vary significantly.
Design 10 – Versatile and Widely Available
Design 10 is Hager’s most popular consumer unit and the go-to choice for many everyday domestic installations. It’s stocked off the shelf by most electrical wholesalers, including Electrical4Less.
- Ample internal space for RCBOs and cable management.
- Top-mounted neutral and earth terminal rail for tidy wiring.
- Multiple fixing points and a full metal DIN rail for easy and secure device installation.
- Available in both surface- and flush-mounted models.
➡️ We also keep a wide selection of accessories for Hager Design 10 boards in stock.
Design 30 – Cleaner Aesthetics, Easier Installation
The Design 30 consumer unit improves upon Design 10 by introducing thoughtful upgrades that simplify installation while enhancing the external look.
- Supplied with a rear cable entry plate and pre-installed cable clamp for incoming meter tails.
- Eliminates stress on switch terminals and maintains safe, neat connections.
- Created for customers who want a tidy board that looks good even when visible.
- Note: Design 30 boards have longer lead times—please enquire in advance before ordering.
Design 50 – Premium Flush Fit for Modern Interiors
Design 50 is Hager’s high-end consumer unit range, focused on seamless home integration and clean presentation.
- Fully flush-fitting design for a near-invisible appearance on finished walls.
- Includes cable protector plates, incoming clamps, and rear entry options.
- Offered in various finishes, sizes, and colours to match contemporary interiors.
- Made to order—please plan ahead as lead times can be significant, but the finish is worth the wait.
RCBO & SPD Compatibility with All Ranges
All Hager consumer units in the Design series are compatible with:
- Hager Type A RCBOs (6kA), including:
- ADA RCBOs: 6–32A (compact size) 40A, 45A, 50A (standard size)
- ADC RCBOs: Compact bi-directional, Curve C, 6–32A
Hager SPDs are currently 2-module devices and fit all board types. While many other brands now use single-module SPDs fitted directly to the busbar (without an MCB), Hager maintains its established SPD configuration—for now.
⚡ Hager EV Circuit Protection Using Standard Consumer Units

When fitting EV chargers that draw a constant 32A, Hager’s dedicated 1P+N Type A RCBOs offer a neat solution—without needing a separate EV consumer unit.
These double-module RCBOs are designed so that only the line terminal is live and the neutral is a dummy. As a result, they are fully compatible with standard busbars in Hager consumer units such as Design 10 and Design 30.
This setup allows electricians to deliver EV-ready installations using the same boards they already know and trust—no rewiring or special enclosure required.

Hager KF Prong Terminals for Larger Earth Conductors
Explore Hager KF Prong Terminals
Hager KF prong-style terminals are essential when terminating earth conductors larger than 16mm² directly into a Hager consumer unit—such as when using 25mm² SWA (steel wire armoured) cables. These prong terminals are designed to slot directly into the busbar system, offering a solid and secure connection point where traditional earth bars may not suffice.
Available options include:
- KF81A – 1x25mm² prong terminal
- KF82A – 2x16mm² prong terminal
- KF83D – 1x35mm² prong terminal
These terminals are ideal when upgrading consumer units or installing boards where larger protective bonding or earth tails are in use.
