A full rewire isn't just about replacing old wires—it's about modernising an entire property's electrical system to meet today’s safety and efficiency standards. Whether you're upgrading an old home, refurbishing a commercial space, or recovering from an Electrical emergency, the team at RCD Electrical, based in North London, is here to help with expert care and bespoke solutions.
Let’s explore what a full rewire really involves and why RCD Electrical is trusted across the region.
What Is a Full Rewire?
A full rewire is a complete replacement of all electrical wiring, switches, sockets, and the consumer unit (commonly known as the fuse box) within a property. This ensures everything complies with the latest UK Wiring Regulations (BS 7671) and Building Regulations. It also gives you the chance to optimise your electrical layout—adding sockets, integrating smart home features, or preparing for electric vehicle chargers.
Rewiring isn't just about functionality—it's a crucial investment in safety and future-proofing.
1. Initial Consultation & Property Survey
At RCD Electrical, every rewiring project starts with a detailed survey. One of our fully qualified electricians visits your property to assess the condition of your existing wiring. This includes checking for outdated or unsafe materials (such as rubber-insulated cables), testing the current load on circuits, and inspecting the consumer unit.
You’ll have a chance to discuss your specific needs:
-
Do you want extra sockets?
-
Are you planning to add underfloor heating or an EV charger?
-
Do you need smart lighting or security features?
Based on your input and our inspection, we provide a clear, itemised quote—no jargon, no hidden fees.
2. Tailored Planning & Electrical Design
Once we’ve agreed on the scope, we create a custom electrical plan. This includes:
-
Mapping out new circuits.
-
Planning the locations of sockets, switches, and lighting fixtures.
-
Designing for current needs while considering future technologies.
We make sure the plan complies with British Standards and takes into account energy efficiency, accessibility, and flexibility.
This is also where we design around your lifestyle. Need bedside USB sockets? Want dimmer switches in the lounge? No problem—we work around your needs, not the other way around.
3. Removal of Old Wiring
With the plan in place, the rewiring process begins by removing the old, often hazardous, wiring.
In many older homes, especially those built before the 1970s, you’ll still find:
Our team removes all unsafe components carefully, with minimal damage to walls and ceilings. Where required, we bring in specialists to handle any hazardous materials like asbestos, which can be found in some old electrical installations.
4. Installing New Wiring, Sockets & Consumer Unit
We then install new, high-quality copper wiring with modern PVC insulation, routed efficiently and neatly. Key elements of this stage include:
-
Installing brand-new circuits tailored to room usage
-
Adding modern sockets, including USB and smart options
-
Installing a new consumer unit with Residual Current Devices (RCDs)
-
Wiring for features such as extractor fans, outdoor lighting, or smart thermostats
The consumer unit plays a central role. Modern units are much safer than their predecessors, automatically shutting off power in the event of a fault or short circuit. This is essential in preventing fires and electric shocks.
5. Comprehensive Testing & Certification
Once installation is complete, we perform full testing to ensure the entire system is safe and functional. This includes:
Only after every element passes our rigorous checks do we issue the Electrical Installation Certificate (EIC), which proves that the system meets UK safety standards.
If your project is part of a home renovation or property sale, we can also provide an Electrical Installation Condition Report (EICR), which is especially useful for landlords and letting agents.
6. Finishing Touches & Cleanup
After testing, we complete the "second fix"—that is, installing faceplates, switch covers, light fittings, and any decorative finishes agreed upon.
Unlike many contractors who leave a mess behind, RCD Electrical takes pride in treating your home with care. We clean thoroughly and, if required, help restore any cosmetic damage (minor plasterwork, paint touch-ups, etc.).
When we leave, your property is safe, clean, and ready for everyday use.

When Might You Need a Full Rewire?
You should consider a full rewire if:
-
Your property is over 30 years old and has never been updated
-
You're experiencing frequent power trips or fuse blowouts
-
Sockets or switches are warm, cracked, or discoloured
-
You’ve noticed buzzing sounds or flickering lights
-
You’re planning major renovations or a loft conversion
-
You’ve had a recent electrical emergency
Even if everything appears fine, old wiring might be a silent hazard. A professional inspection can determine whether a full or partial rewire is necessary.
Electrical Rewiring & Emergencies: Stay Prepared

Water-damaged wiring after a leak or flood
In these situations, we respond swiftly to secure your property, make it safe, and provide a long-term solution.
Often, an emergency reveals deeper issues in the system—leading to the recommendation for a full rewire.
