Your Fuse Box Upgrade Worries Answered in North London
Worried about mess, losing power, how the new unit will look or unexpected extras? Here is what we check and agree before installation.
Will replacing my fuse box make a mess in my home?
We protect the area around the existing fuse box and keep the work centred there wherever possible. If new cables, casing or access work is needed, we show you where it will go and agree it before starting, so you know what will be visible and what making-good is included.
Will I be left without power for days?
The electricity must be switched off while the old board is removed and the new one is connected and tested. We usually aim to complete the main replacement work and restore power within 3–4 hours. If testing finds a fault that prevents safe reconnection, we explain it before carrying out any additional work.
What will the new fuse box look like?
Before work starts, we explain the likely size and position of the new metal consumer unit. The circuits are clearly labelled, and if a larger enclosure, cupboard alteration or visible cable casing may be needed, we agree the appearance with you first.
What happens if testing finds an existing fault?
Pre-change testing can reveal a fault that the old fuse box did not show. If that happens, we explain the problem and its effect before carrying out extra work. The quotation keeps any additional repair separate and states the testing, certification and Building Control notification included where applicable.
Fuse Box / Consumer Unit Replacement Across All 8 North London Boroughs
North London properties do not all present the same electrical layout. The survey separates Victorian & Edwardian Terraces from 1920s–1970s Semis & Detached before the work is specified.
That distinction guides access, circuit testing and the written consumer unit replacement scope without relying on unsupported assumptions about the address.
Boards we typically install: FuseBox 8–12 way RCBO for the standard 3-bed semi, Wylex / Hager full-RCBO 16+ way for larger detached or HMO conversions, and per-flat AFDD-protected boards for multi-let properties. Type 2 SPD on every install, no exceptions. Tap your borough below to see local pricing, real-job examples, and licensing details.

Signs Your Property Needs a New Fuse Box / Consumer Unit
Six tells we look for in fuse-box surveys across North London. 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
AFDD requirements depend on the installation, the current requirements of BS 7671 and any property-specific HMO licence conditions. An HMO inspection may identify additional circuit protection required by the installation design or licence conditions. The board and protective devices must be selected for the individual property.
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. Many standard consumer-unit replacements can be completed in one planned visit; circuit condition, access and remedial work can extend the timescale.
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 written quotation after the survey.
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.

Consumer Unit Upgrade Planning for North London Property Types
Four property situations that change access, testing and the practical scope in North London.
Swipe to explore all property types
Victorian & Edwardian Terraces
📍 Edmonton, Palmers Green, Crouch End, Hornsey, Kilburn, Walthamstow
How is the right consumer unit chosen for Victorian & Edwardian Terraces? The visible ways and labels on an old fuse box do not confirm the real circuit count, condition or loading, so a standard package cannot be chosen safely from a photograph alone.
For Victorian & Edwardian Terraces, planning around whole-property circuit planning means older cable types, previous alterations and the earthing arrangement are checked before the new protective devices are selected. This prevents the replacement from being based on a generic package or an unreliable old label. The written scope follows the checked layout around Edmonton.
1920s–1970s Semis & Detached
📍 Southgate, Cockfosters, Mill Hill, Wembley, Sudbury, Chingford, Wanstead
Will existing circuit faults be found before 1920s–1970s Semis & Detached is transferred? Older alterations, shared neutrals or unidentified conductors can affect an RCBO upgrade. These need to be found before circuits are moved, not after the new board is already in place.
Before RCBO protection is added for kitchen and appliance loads in 1920s–1970s Semis & Detached, circuit identification, insulation resistance and neutral arrangements are checked before individual RCBOs are connected. Any defect found by testing is scoped separately instead of being hidden by the board change. The written scope follows the checked layout around Southgate.
Modern New Build & Regeneration
📍 Meridian Water, Stratford, Royal Docks, Wembley Park, Tottenham Hale, Blackhorse Lane
How long will the power be off in Modern New Build & Regeneration? The shutdown depends on safe access, circuit count and faults found during testing. We plan the isolation around the people and equipment that will be affected.
For protective-device coordination affecting Modern New Build & Regeneration, access, isolation authority and any building-management requirements are confirmed before the appointment. That keeps the power-off period tied to a verified circuit plan and the people affected by it. The written scope follows the checked layout around Meridian Water.
HMO Conversions & Multi-Let
📍 Edmonton, Tottenham, Hackney, Kilburn, Walthamstow, Forest Gate, Ilford
What will the new board and handover look like for HMO Conversions & Multi-Let? A neat enclosure still needs usable labels, appropriate spare capacity and documents that match the circuits actually connected. Appearance and technical handover are planned together.
An upgrade allowing for extensions and external supplies in HMO Conversions & Multi-Let starts with one clear boundary: the circuit schedule records new provision and genuine spare capacity without presenting unused ways as unlimited future load capability. The documents then describe the installation actually completed rather than a standardised assumption. The written scope follows the checked layout around Edmonton.

How much does a fuse box replacement cost in North London?
Standard 5–7 way RCBO board from £800; 8–12 way premium board from £950; 16+ way large-property board from £1,200. HMO compliance pack with per-flat boards + AFDDs is quoted bespoke after survey (typically £1,500–£2,500+ per property depending on flat count).
All prices include FuseBox / Wylex / Hager unit, 100A main switch, 25mm meter tails, Type 2 SPD, full BS 7671 testing, Electrical Installation Certificate, and Building Control notification through our NICEIC registration. Fixed price after free survey — no hidden extras.
Which North London boroughs do you cover?
All 8: Enfield, Barnet, Haringey, Hackney, Brent, Waltham Forest, Redbridge and Newham. Every postcode in those boroughs is served from our Edmonton (N18) base, with same-week survey availability across the region. Tap your borough above for local pricing, real-job examples and HMO licensing details specific to that council.
Do I need a full rewire too, or just a fuse box?
Most installs we do in North London are board-only. The existing wiring is sound; the board is past its life or the EICR flagged no RCD. 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.
What does HMO licensing require for the consumer unit across the 8 boroughs?
All 8 boroughs require full BS 7671 18th Edition Amendment 2 compliance for licensed HMOs. The minimum is: AFDDs on every bedroom circuit, RCBO per circuit (no shared RCDs), per-flat consumer units on multi-let properties, and a 5-yearly EICR. Newham, Hackney and Brent run the strictest licensing regimes; Barnet, Enfield, Haringey and Waltham Forest run Article 4 / selective licensing in much of the borough.
We do the full HMO compliance pack as one job: per-flat boards, AFDDs, BS 5839-6 alarm interface, EI4 emergency lighting, and EICR at handover suitable for licensing submission.
How long does a fuse box replacement actually take?
Plan for 3–4 hours on site for a standard install, with one short 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.
Will my new board pass EICR and 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 the applicable certificate within the timescale confirmed for the job. 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.
