Why do many electricians and homeowners still refer to the consumer unit as a “fuse box” in 2025? Although the official name has been standardised in regulations for decades, the term fuse box remains deeply rooted in everyday language. This post explores the journey from fuse boxes to FuseBox consumer units, unpacks the brand’s role in keeping the term alive, and explains how evolving regulations continue to shape the UK’s electrical landscape.

Our team is committed to fast service, clear advice, and an easy ordering experience—backed by tracked next-day delivery from reliable UK couriers.
The FuseBox Brand: A Clever Revival of a Familiar Name
The FuseBox brand, launched in 2017 by CP Electric Ltd in Kilmarnock, Scotland, is now a recognised leader in UK circuit protection. Under the direction of Robin Forsyth, the company quickly became known for building robust, installer-friendly metal consumer units that meet evolving 18th Edition standards.
With a compact team and dedicated field agents, FuseBox expanded rapidly across the UK and Ireland, supplying over 1,200 wholesalers. Products are manufactured in partnership with facilities in Europe and Asia, and include features like:
- Top-mounted earth and neutral bars
- Plenty of wiring space
- Factory-fitted Type 2 SPDs
- Full compliance with BS EN 61439-3 and BS 7671:2018+A2
This clever re-use of the nostalgic “fuse box” term likely helped the brand’s early popularity. It resonated with homeowners and experienced electricians alike—and from 2018 to 2019, word-of-mouth and wholesaler demand helped FuseBox take off.
Why Are We Still Saying “Fuse Box”?
We’ve been trying to pinpoint exactly when “consumer unit” became the formal term in the UK. Our research suggests:
- The term “consumer unit” began appearing in British Standards from the 1960s onward
- It was formalised in documents like BS 5486-13:1979 and BS 7671 (then the IEE Wiring Regulations)
- Even today, BS 7671 (18th Edition) uses only “consumer unit”—you won’t find “fuse box” in modern regulations
Yet the term fuse box persists, especially in domestic settings. Why?
Because FuseBox, the brand, brought it back. Their success helped reinforce the old term with a new product identity. Now, phrases like “FuseBox consumer unit” dominate search results and wholesaler websites alike.
If you know of any earlier uses of “consumer unit” or specific standards where the terminology shifted, let us know! We’re always updating our knowledge and would love to include better references.

⚡ Introducing the F3 Series – FuseBox’s Latest Innovation (2025)
FuseBox launched their brand-new F3 Series in 2025, representing their most advanced consumer unit design yet.
Key differences:
- SPD does not require an MCB – it fits directly onto the busbar
- No wasted ways – with the MCB removed, you gain an extra usable way (e.g. 6-way unit becomes 7-way)
- SPD colour change – from the older orange to a modernised pink finish
The F3 range also supports bi-directional RCBOs, making it perfect for solar PV systems and EV charger-ready installs. This series improves layout flexibility and saves on parts—further cementing FuseBox as a forward-thinking manufacturer.
