Your Fuse Box Upgrade Worries Answered in Brent
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 the Borough of Brent
Brent properties do not all present the same electrical layout. The survey separates Pre-WWI Terraces from 1920s–1930s Metroland Semis 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 across Brent: FuseBox 10–12 way RCBO for the standard semi or terrace, per-flat AFDD boards for HMO conversions in Kilburn and Harlesden, and 16+ way RCBO + future high-load equipment-prep for larger Kingsbury and Sudbury detached properties.

Signs Your Brent Property Needs a New Fuse Box / Consumer Unit
Six tells we look for in Brent 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
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 Brent Property Types
Four property situations that change access, testing and the practical scope in Brent.
Swipe to explore all property types
Pre-WWI Terraces
📍 Kilburn, Queens Park, Kensal Green, Cricklewood
How is the right consumer unit chosen for Pre-WWI 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 Pre-WWI Terraces, planning around terraces & converted houses means the real circuit schedule, supply, earthing and bonding are verified before the enclosure and protective devices are specified. This prevents the replacement from being based on a generic package or an unreliable old label. The written scope follows the checked layout around Kilburn.
1920s–1930s Metroland Semis
📍 Wembley, Sudbury, Kingsbury, Alperton
Will existing circuit faults be found before 1920s–1930s Metroland Semis 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 high-density apartment buildings in 1920s–1930s Metroland Semis, shared supplies, borrowed neutrals and circuit ownership are resolved before individual RCBO protection is 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 Wembley.
Post-War Estates & Wembley Park
📍 Harlesden, Stonebridge, Neasden, Wembley Park new builds
How long will the power be off in Post-War Estates & Wembley Park? 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 maisonettes & split-level homes affecting Post-War Estates & Wembley Park, the isolation plan identifies who authorises access and which occupied or communal services must remain available. 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 Harlesden.
HMO Conversions & Multi-Let
📍 Kilburn, Harlesden, Willesden, Cricklewood
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 home offices & small workspaces 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 Kilburn.

Consumer Unit Upgrade Questions for Brent
Property-specific questions for Brent, followed by practical answers about consumer unit replacement.
Do you cover the full London Borough of Brent for fuse box replacement?
Yes — we cover Wembley, Harlesden, Willesden, Neasden, Dollis Hill, Kingsbury, Sudbury, Alperton, Kensal Green, Kilburn, Queens Park and Cricklewood. NW2 / NW6 / NW9 / NW10 / HA0 / HA9 postcodes all served from our Edmonton base.
What does Brent Council require for an HMO consumer unit?
Brent runs borough-wide additional HMO licensing across most of NW6, NW10 and HA0. Electrical requirement is full the current edition of BS 7671: AFDDs on bedroom circuits, RCBO per circuit, per-flat board on multi-let, 5-yearly EICR. We do the full HMO pack including BS 5839-6 alarm interface and EICR at handover suitable for licensing.
My Kilburn or Cricklewood landlord EICR failed on no RCD — is that a board fix?
Yes — the standard fix across NW6 and NW2. Replace the existing pre-RCD board with a modern RCBO consumer unit (typical scope £800–£1,200), EICR re-test same day. We can quote without a site visit if you send us the report.
How fast can you respond for emergency fuse box failure in Brent?
Typically 3–5 hours daytime across the borough from our Edmonton base. We carry FuseBox / Wylex stock for Planned Installations. Call 07932 772050 for emergency response.
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 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.
