Consumer unit replacement for London landlords
Many older rental properties across London still have rewirable fuse boards that lack the RCD (Residual Current Device) protection required by the 18th Edition Wiring Regulations (BS 7671:2018+A2:2022). A failed EICR that codes the consumer unit as C2 (potentially dangerous) triggers a 28-day remediation deadline — replacing the consumer unit is typically the fastest resolution.
We supply and install high-quality metal consumer units from Hager, Legrand, and Crabtree — brands trusted by electricians for their reliability and longevity. Every installation includes a full circuit test and completion EICR to confirm the work is safe and compliant.
As NICEIC approved contractors, we self-certify all installations under Part P of the Building Regulations. You receive a Building Regulations compliance certificate automatically, with no need to separately notify your local authority.
How it works
1
Book and confirm specification
Book online or call us. We confirm the number of circuits in your property and agree the consumer unit specification (split-load dual RCD or individual RCBOs).
2
Installation day (4–6 hours)
Our NICEIC approved electrician arrives, isolates the supply, removes the old board, installs and connects the new consumer unit, then tests every circuit before restoring power.
3
EICR and Part P certificate
We issue the completion EICR on the day. Your Part P Building Regulations certificate follows within a few weeks, notified to NICEIC on your behalf at no extra cost.

Why older London properties need a new consumer unit
Many pre-2000s rental properties across London still have rewirable fuse boards or early consumer units that lack the RCD protection required by the 18th Edition Wiring Regulations (BS 7671:2018+A2:2022). These boards were installed when standards were less stringent and cannot be upgraded — replacement is the only compliant solution.
The problem with old fuse boards
- ✓Rewirable and cartridge fuse boards provide overcurrent protection only — they cannot detect earth faults or shock currents
- ✓No RCD protection means a fault to earth or a person contacting a live part may not be disconnected fast enough to prevent serious injury
- ✓The 18th Edition requires RCD protection on all socket outlets rated up to 32A in dwellings — old boards cannot be updated to meet this requirement without full replacement
- ✓An EICR that codes the consumer unit as C2 (potentially dangerous) triggers a 28-day remediation deadline — replacement is typically the only resolution
What RCDs and RCBOs do
An RCD (Residual Current Device) monitors the current flowing in and out of a circuit. If there is an imbalance of as little as 30mA — indicating current is flowing through a person — it trips within 40ms, fast enough to prevent a fatal shock. RCBOs (Residual Current Breakers with Overcurrent protection) provide both overcurrent and earth fault protection per individual circuit, giving maximum protection and making faults much easier to isolate without disrupting the whole property.
Part P of the Building Regulations
Consumer unit replacement is notifiable work under Part P of the Building Regulations (England). Either a Building Control notice must be submitted before work starts, or the work must be carried out by a registered competent person scheme member who can self-certify. As NICEIC approved contractors, we self-certify on your behalf — you receive a Building Regulations compliance certificate at no extra charge, automatically, without any contact with your local authority.

“I’ve now used this company four times and can honestly say they’ve been brilliant from start to finish.
I originally found them after being let down repeatedly by another company (to the point where I’m now having to take legal action), so I was understandably very nervous about using someone new. I’m so glad I chose them.
They’ve carried out EICRs, Fire Risk Assessments, a substantial package of follow-on fire safety works, and I’ve now booked them again for another Fire Risk Assessment, EICR and an Asbestos Management Survey.
Every member of the team has been incredibly responsive, professional and helpful. They’re always happy to answer questions, no matter how many you have, and they never make you feel like you’re a burden. Communication has been excellent throughout, which is something I really value.
On the larger follow-on works, they initially quoted two days to complete the job but actually finished it in just over one day, which was a fantastic surprise. Although I wasn’t present during the Fire Risk Assessment at one of the blocks, one of the directors there commented on how friendly and helpful their surveyor was. One of my own team members, who met him on site, said exactly the same.
Overall, I’m genuinely impressed with the quality of their work, their professionalism and how easy they are to deal with. They’ve gone above and beyond on every project we’ve given them, and they’ll continue to be my first choice for compliance work. I wouldn’t hesitate to recommend them.”
“Spot on service from John from start to finish. Booked an EICR online and the engineer turned up right on time. Certificate sent over the next morning.”
