Local Fuse Box Installer in London | NICEIC Certified
London properties don’t all need the same solution. A 1930s semi in Barnet has completely different electrical demands than a new-build flat in Stratford. My Local Electrician has been installing fuse boxes across all 32 London boroughs for over a decade, and we know the difference.
Our NICEIC-approved electricians arrive stocked and ready, complete the work to BS 7671, and hand you a legally valid certificate before they leave. Every installation is fully insured. Every job carries a written workmanship warranty.
Over 100 five-star Google reviews back every word of that. Call us today and get your installation booked.
The London Fuse Box Installer Locals Actually Recommend
Choosing the right fuse box installer in London matters more than most people realise. A badly specified or uncertified consumer unit can void your home insurance, fail a conveyancing inspection, and put your family at risk.
Here’s why thousands of London residents and landlords call us first:
✓ 12 Years in London: We’ve worked inside London’s electrical infrastructure longer than most companies have existed. Victorian wiring, aluminium circuits, non-standard layouts; nothing we encounter in this city surprises us anymore.
✓ Fully NICEIC Accredited: Every fusebox installer we send is individually NICEIC-certified. That means your installation certificate is legally recognised, accepted by insurers, mortgage lenders, and solicitors without challenge.
✓ Honest Recommendations Only: We never push a full board replacement when a targeted fuse box repair will do the job. If you need a new consumer unit, we’ll tell you why clearly. If you don’t, we’ll tell you that too.
✓ Same-Day Availability: Most fuse box installations are completed the same day you call. We carry consumer units, MCBs, RCBOs, SPDs, and associated components in our vans so work starts the moment we arrive, not days later.
✓ Affordable and Transparent: You receive a fixed price before we touch anything. No hourly rate surprises, no call-out fees buried in the small print.
✓ Insured and Warranted: Public liability insurance covers every visit from start to finish. A written workmanship warranty covers every installation after we leave. You’re protected either way.
How We Handle Your Fuse Box Installation, Step by Step
Our local fuse box installers in London follow a proven step-by-step process to ensure a safe and seamless installation. Here is how our service works:
Step 1
Book Your Slot
Contact us by phone, WhatsApp, or online. Describe your property briefly and we’ll confirm the earliest available appointment, usually the same day.
Step 2
Property Assessment
We inspect your existing wiring, current board condition, incoming supply, circuit count, and any visible issues before recommending a specification.
Step 3
Your Upfront Quote
We present a fixed price covering labour, components, and certification. You approve it before a single wire is touched. No grey areas.
Step 4
Safe Isolation
Mains supply is correctly isolated using calibrated instruments and appropriate PPE. Every downstream circuit is identified and labelled before installation begins.
Step 5
Board Installation
Your new consumer unit is fitted and wired to BS 7671. MCBs, RCBOs, and surge protection devices are correctly specified per circuit and torqued to manufacturer requirements.
Step 6
Test and Certify
All circuits are tested post-installation. An Electrical Installation Certificate is issued, along with a full circuit schedule and written installation report for your records.

Types of Consumer Unit We Install Across London
Every property is different and the right board depends on your circuit count, building type, and protection requirements. We install and specify all of the following across London.
✓ Dual-RCD Split-Load Unit
Two RCDs protect separate groups of circuits. A fault on one side trips half the board, not the whole property. A practical and cost-effective choice for straightforward domestic upgrades, particularly in properties with a moderate circuit count where per-circuit discrimination isn’t critical.
✓ Fully RCBO Consumer Unit
Each circuit has its own RCBO combining overload and earth leakage protection. A tripped circuit affects only that circuit. Nothing else goes down. This is increasingly the default specification for London domestic installations and the one most insurers and letting agents expect to see.
✓ High-Integrity Consumer Unit
A dual-RCD board with selected circuits broken out onto individual RCBOs. Keeps critical loads like freezers, alarms, or medical equipment online during a fault elsewhere. An ideal middle ground for households where losing certain circuits entirely isn’t acceptable.
✓ Consumer Unit with Surge Protection
Voltage spikes from nearby lightning or grid switching events can destroy sensitive electronics instantly. We install and replace consumer units with integrated or separate surge protection devices in line with BS 7671:2018 Amendment 2. Particularly relevant for London homes with smart systems, home offices, or high-value appliances.
✓ AFDD-Protected Consumer Unit
Arc Fault Detection Devices identify dangerous electrical arcing inside walls before any standard breaker would react. Increasingly required in new builds and refurbished London properties under the 18th Edition Wiring Regulations. Our team is trained and experienced in AFDD specification and installation.
✓ HMO-Specified Consumer Unit
Houses in Multiple Occupation require a board correctly specified for the building’s occupancy, load profile, and licensing conditions. We install HMO consumer units with full certification under the Electrical Safety Standards (Private Rented Sector) Regulations 2020, and combine this with EICR work at the same visit where needed.
✓ Rewirable Board Replacement
Wire fuse boards found in older inner London properties, particularly across Hackney, Islington, Lewisham, and Southwark, offer no RCD protection at all. Replacing one with a modern consumer unit is one of the single most effective safety improvements a London homeowner can make. We carry out these upgrades regularly.
✓ Commercial Distribution Board
Offices, restaurants, retail units, and warehouses use commercial-grade distribution boards rather than domestic consumer units. We install and certify commercial DBs to BS 7671 with full commercial documentation, available around the clock for business-critical projects.

What Does a New Fuse Box Installation Cost in London?
Fuse box replacement cost depends primarily on three things: how many circuits your property has, what type of consumer unit is specified, and whether any remedial work is needed before the board can be correctly certified. A small flat with six circuits costs less than a five-bedroom house with sixteen.
Adding AFDD protection or surge devices increases the component cost. Older properties sometimes need earth bonding improvements or circuit remediation before a compliant certificate can be issued.
We confirm your exact price on-site and nothing starts without your approval.

Dual-RCD Unit, up to 10 circuits | £350 – £500 |

Frequently Asked Questions About Local Fuse Box Installation in London
➔ How long does a standard consumer unit installation take in London?
Most domestic installations take between three and five hours. Larger properties with more circuits, or older homes needing additional bonding work, can run longer. We give you a realistic time estimate before starting so you can plan your day accordingly.
➔ Can I choose where my new consumer unit is positioned?
In most cases yes, subject to practical constraints around cable routing and proximity to the incoming supply. Repositioning a board further from its current location adds to cost and time. We’ll advise on the most practical options during the assessment.
➔ Do I need to notify my landlord before installing a new consumer unit?
If you’re a tenant, yes. Consumer unit installation is a notifiable alteration under Part P of the Building Regulations. You’ll need your landlord’s written permission before work can legally proceed. We can provide a written scope of works to support that conversation if helpful.
➔ What happens to my existing circuits when the new board is installed?
Your existing circuit cables connect into the new board during installation. We check every cable for condition and correct rating before terminating into the new unit. Any circuit found to be unsafe is flagged clearly and won’t be connected until the issue is resolved.
➔ Will a modern consumer unit prevent all electrical faults?
No. A correctly specified consumer unit improves protection significantly, but it doesn’t fix underlying wiring faults, ageing cables, or incorrectly installed circuits. It reacts to faults rather than preventing them. We always advise combining a board upgrade with a full EICR in older properties.
➔ Is it worth upgrading to a fully RCBO board versus a standard dual-RCD unit?
For most London homeowners, yes. The additional cost over a basic dual-RCD board is relatively modest and the benefit is real: a fault on one circuit doesn’t affect any other. It also tends to satisfy insurers and letting agents more readily.
➔ Can a new fuse box installation support EV charging or solar panels?
A correctly specified modern consumer unit is the foundation for both. EV chargers and solar PV systems require dedicated circuits and appropriate protection devices. We assess your existing capacity and specify the board to accommodate these additions, either now or as a future upgrade.
➔ What if my meter or incoming supply is also problematic?
The incoming supply up to and including your meter is owned by your Distribution Network Operator, not your electrician. If we identify a supply-side issue, we’ll tell you clearly, advise you to contact your DNO or energy supplier, and explain exactly what’s outside our scope and why.
➔ Does the installation come with any paperwork I can give to my insurer?
Yes. Your Electrical Installation Certificate and written installation report are fully accepted by insurers, mortgage lenders, and solicitors. NICEIC certification means the documentation is issued by an accredited scheme and carries legal weight. Keep it somewhere safe alongside your property deeds.
➔ How often should a consumer unit be inspected after installation?
Owner-occupied properties should have an EICR carried out every ten years as a general recommendation. Rental properties are legally required to have one every five years under the 2020 private rented sector regulations. HMOs are subject to their own licensing inspection requirements. We carry out EICRs across London and can schedule one alongside your installation.
