Old vs New — Which is in your home?
If your board looks anything like the one on the left, it’s not just outdated — it may be putting your family, your belongings, and your insurance at risk. Here’s the difference a modern consumer unit makes.
Old Split-Load Board
- Half the circuits NOT RCD protected
- Wiring from two versions of BS 7671
- Last inspected 2019 — now overdue
- No surge protection (SPD)
- One fault knocks out a whole bank
New 18th Edition Metal Consumer Unit
- Every circuit individually RCBO protected
- Built-in SPD — protects against surges
- Meets current BS 7671 amendments
- Fire-resistant steel enclosure
- One fault = one circuit, not your whole house
6 Warning Signs You Need a New Fuseboard
If you spot any one of these, it’s time for a professional survey. If you spot two or more, don’t wait.
Plastic or wooden enclosure
The 18th Edition requires non-combustible metal consumer units in domestic properties. Plastic boards have been linked to house fires.
No RCD protection
Modern regs require RCD (residual current device) protection on every circuit. Without it, a fault could mean serious shock or fire.
Rewireable fuses
BS 3036 rewireable fuses are obsolete. They trip slowly, can be “fixed” with the wrong wire, and offer almost no protection.
No surge protection (SPD)
BS 7671 now requires surge protective devices. One lightning strike on the street can fry every device in your house without one.
Grouped RCDs
On older split-load boards, one fault takes out half the house — upstairs lights, freezer, the lot. RCBOs only trip the faulty circuit.
Burn marks, buzzing, or constant tripping
Scorching, humming, or a breaker that keeps tripping are warning signs of loose connections or an overloaded, ageing board.

Why RCBOs Beat Old Split-Load Boards
Every MP Electrical fuseboard upgrade uses individual RCBOs — one per circuit. Here’s why that matters.

One circuit, one device — no guessing which of six circuits on a shared RCD is the problem.
🏠 Future-proof
Ready for EV chargers, solar PV, heat pumps and home batteries without another upgrade.
📜 Regs-compliant
Meets the latest amendments to BS 7671 — keeps your insurance valid and your EICR clean.

Frequently Asked Questions
How long does a fuseboard upgrade take?
Most standard domestic upgrades take 4–6 hours. Your power will be off for most of that time, but you’ll have it back on the same day.
Will I have to notify Building Control?
No — MP Electrical is NAPIT registered, so we handle the Part P Building Control notification for you and the certificate is posted directly to your home.
My current board still works — do I really need a new one?
“Working” isn’t the same as “safe”. Many old boards have no RCD protection on some circuits, use combustible plastic enclosures, or pre-date surge protection requirements. A quick survey will tell you exactly where yours stands.
What’s included in the price?
A modern 18th Edition metal consumer unit, individual RCBOs for every circuit, SPD surge protection, full testing, your Electrical Installation Certificate, and Part P notification. No hidden extras.
Do you offer a warranty?
Yes — all workmanship is guaranteed and the consumer unit itself comes with the manufacturer’s warranty. You’re also covered by NAPIT’s insurance-backed guarantee.
How much does it cost?
Prices start from around £650 for a straightforward domestic upgrade, depending on circuit count and condition of the existing wiring. You’ll get a fixed written quote before any work begins.
