Warning Signs

Why Replace Your Consumer Unit?

Missing RCD Protection
Older units may lack RCD or individual RCBO protection — essential for safety under BS 7671. Without it, a fault could be fatal.
Degraded & Ageing Boards
Plastic fuse boxes degrade over time. Melting, overheating and corrosion can lead to electrical fires. A buzzing or warm board needs attention.
Insurance & EICR Issues
Outdated consumer units frequently fail EICR inspections, can invalidate home insurance, and may breach current safety regulations.
Preparing for EV or Extensions
Adding an EV charger, garden office, or extra circuits? An upgraded consumer unit provides the capacity and spare ways you need.
Frequent Tripping
Nuisance trips taking out half the house at once? An RCBO board means a fault on one circuit affects only that circuit. Fewer trips, easier fault-finding.
Peace of Mind
A new consumer unit is the backbone of your home's electrical safety. Better protection, fewer trips, and paperwork to prove compliance.

RCBO vs Dual-RCD

Which Type of Board Is Right for You?

We'll price both and explain which is best for your property layout and loads. Here's the key difference:

Standard Option
Dual-RCD Board
Circuits are protected in two groups by RCDs. A fault can trip one group at a time. Lower cost, but nuisance trips may affect multiple circuits simultaneously.
Recommended
RCBO Board
Each circuit has its own RCBO. A fault on one circuit only affects that circuit. Fewer nuisance trips, faster fault-finding, and the safest option for modern homes.
Also Worth Considering

SPDs (Surge Protection Devices) are now widely recommended to protect sensitive electronics. AFDDs (Arc Fault Detection Devices) are recommended in specific scenarios for higher-risk settings. We'll advise case-by-case.

Step by Step

What Happens on the Day

When we replace your old fuse board with a modern consumer unit, we follow a clear step-by-step process so you know exactly what to expect.

Power Isolation
We safely isolate the supply and verify the system is completely dead before starting any work.
Circuit Testing
Each existing circuit is tested for insulation resistance, continuity and polarity to confirm it's suitable for connection to the new board.
Removal & Preparation
The old unit is removed, the wall prepared, and a new metal-clad enclosure securely fitted in place.
Re-termination & Protection
Circuits are reconnected, with Surge Protection Devices and either RCBOs or RCDs fitted to meet current regulations.
Final Testing & Labelling
Full BS 7671 tests on every circuit. The board is clearly labelled and your Electrical Installation Certificate is completed.
Compliance Notification
The work is registered with Building Control through our NAPIT scheme. You receive official confirmation it meets all safety standards.

Common Questions

Consumer Unit Replacement — FAQs

Usually half a day to a full day depending on complexity — the number of circuits, ease of access, and condition of existing wiring. We give you a clear timescale before we start and coordinate power isolation around your schedule.
Perhaps — but "working" isn't enough. If safety features are missing (no RCD, no earth bonding, old plastic enclosures, melted wiring) it poses risk. Insurance inspections and EICR reports may demand an upgrade even if the unit appears functional.
If your system fails safety checks (EICR), or the unit is unsafe, then yes it becomes a legal and insurance issue. Even if not strictly required, it's strongly recommended under BS 7671 and Part P of the Building Regulations.
We plan to minimise downtime. There will be a period with the power isolated, but we coordinate timings with you and most customers can move around the property normally during the work. We aim to restore power the same day.
Yes. We offer warranties on both parts (unit, breakers) and labour. All work follows UK regulations and everything is certified via our NAPIT registration with Building Control notification as standard.
