Why Choose Rudi Electrics
for Fuse Box / Consumer Unit Replacement in Barnet?
Your concerns answered — here’s why Barnet homeowners and landlords trust us for fuse box replacement and consumer unit upgrades.
“Will I get a fixed price or surprise extras?”
Fixed price quote after a free survey. We check incoming supply, earthing, circuits and HMO requirements before quoting — the figure you see is the figure you pay. Standard 5–7 way RCBO board from £800; 8–12 way premium boards from £950; 16+ way large-property boards from £1,200.
“How long will my power be off?”
Most installs are completed in 3–4 hours with a single short power-off window. We pre-run new tails, isolate at the main switch, swap the board, and re-energise circuit-by-circuit while testing. Fridge / freezer planning is part of the survey conversation, not a surprise on the day.
“Are you fitting a quality unit, not a cheap import?”
Only FuseBox, Wylex, Hager or Schneider consumer units — never unbranded imports. Type A or AC RCBOs as required, Type 2 SPD as standard, and AFDDs on bedroom circuits where landlord HMO compliance requires it. All BS EN 61439-3 listed.
“Will it pass building control and EICR?”
Every install is notified to Building Control through our NICEIC registration (D609991) and you receive a full BS 7671 18th Edition Amendment 2 Electrical Installation Certificate within 24 hours. Insurer-accepted, mortgage-accepted, and remedial-friendly for any future EICR.
Fuse Box / Consumer Unit Replacement Across the Borough of Barnet
Barnet’s housing stock is genuinely mixed — Edwardian and 1930s semis in Whetstone, Totteridge and Finchley sit alongside 1950s–70s Mill Hill, Hendon and Edgware developments, conservation-area period properties around Hampstead Garden Suburb and Highgate, and a growing number of HMO conversions across Friern Barnet, East Finchley and New Southgate. The fuse boxes we replace reflect that mix: rewireable boards from before 1970, dual-RCD splits from the 1990s, and old-stock unbranded units in the worst HMO conversions.
The most common Barnet jobs we see: EICR-driven replacements after a sale survey flags no RCD, landlord HMO compliance upgrades on Friern Barnet and Arnos Grove multi-let conversions (per Article 4 / mandatory licensing), and load upgrades for kitchen extensions and EV chargers on the larger Mill Hill, Totteridge and Hendon detached properties.
Boards we typically install across Barnet: FuseBox 12-way RCBO for a standard 3-bed semi, Wylex / Hager 16+ way for larger detached homes with EV-prep, and per-flat AFDD-protected boards for HMO conversions. SPD as standard on every install, no exceptions.

Signs Your Barnet Property Needs a New Fuse Box / Consumer Unit
Six tells we look for in Barnet fuse-box surveys. If two or more apply, a board replacement is usually the right call — not a repair.
Tripping that won’t reset
If your RCD trips and resets briefly then drops again the same evening, that’s a fault on a circuit — not a fuse box that just “needs a swap”. We isolate it during the install so the new board doesn’t inherit the same fault.
Burning smell or scorch marks
Brown discolouration around the main switch or burning plastic smell from the meter cupboard means heat damage at the consumer unit. Stop using high-load appliances and call us — this is a same-day priority job.
Wirewound or rewireable fuses
Old porcelain fuse holders with rewireable wire, or cartridge fuses with no MCBs at all, mean the board is from before 1980 and has zero RCD protection. EICR will fail it on C2; insurers may refuse claims.
Failed EICR or insurer refusal
C1 or C2 codes for “no RCD on socket circuits”, “outdated consumer unit”, or “non-compliant with current standards” are all board-level fixes. Send us the EICR and we’ll quote remedial work without a survey.
HMO licensing inspection
Council HMO licensing now requires AFDDs on bedroom circuits (BS 7671 Amendment 2). If your existing board has no AFDDs and you’re renewing a licence, the inspection will flag it. Per-flat boards with AFDD are the standard fix.
Frequent appliance damage
If your TV, fridge, or boiler PCB has died more than once in the last few years, that’s typically a Type 2 SPD problem — older boards have no surge protection. New install adds SPD as standard.
How We Replace Your
Fuse Box / Consumer Unit
Professional install from start to finish. Most fuse box replacements complete in 3-4 hours with minimal disruption to your home.
Initial Assessment
We check your incoming supply, earthing arrangement (TT vs TN-C-S), circuit count, RCD/SPD status, EICR history if any, and confirm whether AFDDs are required (HMO sleeping rooms). The survey is free with no obligation and you get a written fixed-price quote within 24 hours.
Isolation & Removal
DNO main fuse pulled with permission, existing tails isolated, old board removed cleanly. We cap and label every circuit before disconnecting so reconnection is methodical, not guesswork. No live working at any stage.
New Unit Installation
Modern consumer unit (FuseBox, Wylex, Hager or Schneider) fitted with new 25mm meter tails, 100A main switch, full RCBO protection per circuit, Type 2 SPD on the main bus, and AFDDs where required. Cables labelled and torque-checked.
Testing & Verification
Full BS 7671 testing: insulation resistance (every circuit), Zs / Ze loop impedance, RCD trip times, SPD verification, polarity checks, and earth fault path. Any pre-existing fault is logged and discussed before we re-energise.
Fault Finding (If Needed)
If a circuit fails testing on the new board (typically a hidden borrowed neutral or insulation breakdown on an existing run), we find and fix it the same day where possible. Most fixes add £80–£180; major issues are quoted before any extra work starts.
Certification & Handover
Electrical Installation Certificate issued, photographed install record, written labels inside the board, Building Control notification through our NICEIC registration, and a verbal walkthrough of the new RCBOs and SPD test buttons. 12-month workmanship guarantee starts on handover.

Fuse Box / Consumer Unit Replacement Barnet FAQs
Clear answers to the most common questions Barnet homeowners and landlords ask about fuse box replacement, consumer unit upgrades, EICR-driven installs, and HMO compliance.
For official guidance, visit Electrical Safety First or read the Building Regulations guidance.
Do you cover the full London Borough of Barnet for fuse box replacement? ▼
Yes — we cover the whole borough including Finchley, North Finchley, East Finchley, Friern Barnet, New Southgate, Arnos Grove, Highgate, Whetstone, Totteridge, Hendon, Mill Hill and Edgware. EN4 / EN5 / N2 / N3 / N10 / N11 / N12 / N20 / NW7 / NW9 / NW11 postcodes all served from our Edmonton base, typically with same-week survey availability.
My EICR failed in Finchley with C2 codes for ‘no RCD protection’ — is that a fuse box issue? ▼
Yes — that’s the most common failure we fix in N3 / N12 / N2 postcodes. C2 “no RCD on circuits feeding sockets” is a board-level issue: replace with a modern RCBO consumer unit and the failure is resolved. Typical scope £800–£1,200 depending on circuit count, completed in one day, EICR re-test included.
Send us the EICR report and we’ll give you a fixed quote without needing a site visit if the codes are clear.
I’m running an HMO in Friern Barnet / East Finchley — what does Barnet Council require for the consumer unit? ▼
Barnet has Article 4 mandatory HMO licensing across most of the borough. The electrical requirement is full BS 7671 18th Edition Amendment 2 compliance, which means: AFDDs on all sleeping-accommodation circuits, RCBO protection per circuit (not shared RCDs), 5-yearly EICR, and a per-unit consumer unit if there are multiple separately-let units.
We do the full HMO compliance pack as a package: per-flat boards, AFDDs, BS 5839-6 alarm interface, EI4 emergency lighting, and an EICR at handover suitable for licensing submission.
How fast can you respond for an emergency fuse box failure in Barnet? ▼
For total power loss or a board on fire, we’re typically on site in 2–4 hours across Barnet daytime, longer in evenings. We carry FuseBox and Wylex consumer units in stock so a same-day install is realistic if the existing board is beyond repair.
For non-emergency tripping or burning-smell complaints, next-day appointments are standard. Call 07932 772050 and we’ll confirm timing within 30 minutes.
How long does a fuse box replacement actually take? ▼
For a standard domestic install, plan for 3–4 hours on site from arrival to handover, with a single power-off window of about 90 minutes during the swap itself. Larger 16+ way boards or HMO installs with AFDDs run closer to 5–6 hours.
Same-day completion is standard. We don’t leave a job overnight without a working board.
Do I really need to replace my fuse box, or can you just fix the tripping? ▼
Honest answer: it depends on the board. If you have a rewireable or wirewound fuse box (no MCBs or RCDs), or a board with no RCD protection on socket circuits — that’s a replacement, not a repair. BS 7671 18th Edition requires RCD on every circuit feeding sockets and now AFDDs on HMO bedroom circuits.
If you have a modern board with RCBOs and a single circuit is tripping, that’s usually one faulty circuit or appliance — we fault-find and fix that, no replacement needed. The free survey will tell you which it is.
Will my install need a full rewire too, or is it just the board? ▼
Most installs we do are board-only — the existing wiring is sound, just the board is past its life. We test every circuit during installation; if one fails (usually a hidden borrowed neutral or insulation breakdown), we either fix it the same day or quote it separately.
If multiple circuits fail testing, that’s when a partial or full rewire conversation happens. We tell you straight, with the failure data in front of you. No upselling.
Will my new board pass an EICR or insurance inspection? ▼
Yes — every install is to BS 7671 18th Edition Amendment 2, notified to Building Control through our NICEIC registration (D609991), and certified with a full Electrical Installation Certificate within 24 hours.
The certificate is accepted by mortgage lenders, home insurers, landlord licensing schemes, and any future EICR will treat the board itself as satisfactory — only existing-circuit issues from before our work would code on a future inspection.
