A house rewire is the complete replacement of your property's electrical wiring, from the incoming supply to every socket, switch, and light fitting. It includes installing a new consumer unit (fuse box) with modern RCD protection, running new cables throughout the property, and providing full certification and Building Control registration. **A rewire is typically necessary when:** - Your wiring is over 25-30 years old and showing signs of deterioration - You have old-style rubber or lead-sheathed cabling (pre-1970s) - An [EICR inspection](/services/eicr-testing) has identified serious defects - You're undertaking major renovation work - Your current installation lacks adequate socket outlets or circuit capacity - You want to install high-power appliances like [EV chargers](/services/ev-charger-installation) **Who needs rewiring services?** Homeowners in older properties throughout [Croydon](/areas/croydon), [Bromley](/areas/bromley), [Sutton](/areas/sutton), and the wider London area. Victorian, Edwardian, and 1950s-70s properties are particularly likely to need rewiring. Landlords preparing properties for sale or let also benefit from certified modern installations. ![House rewiring in progress with new cables being routed through walls](/assets/house-rewire-progress-BKEqkf-4.jpg) ## The Hidden Dangers of Old Wiring Old wiring doesn't just limit your electrical capacity — it actively endangers your home and family. Deteriorating insulation, inadequate earthing, and outdated protection systems create risks that increase with every passing year. **The real risks of postponing rewiring:** - **Fire hazard:** Old rubber and fabric insulation degrades over time, exposing conductors and creating fire risks. Overloaded circuits generate excessive heat in wiring never designed for modern electrical loads. - **Electric shock:** Deteriorating earthing systems and lack of RCD protection mean faults that should trip safely can instead deliver dangerous or lethal shocks. - **Insurance issues:** Many insurers exclude or limit cover for properties with wiring over a certain age. A fire caused by old wiring may result in a rejected claim. - **Property sale problems:** Surveyors flag old wiring, and buyers negotiate significant reductions or walk away. A recent rewire adds value and removes barriers to sale. - **Inability to upgrade:** Old installations can't safely support modern appliances, home offices, EV chargers, or smart home systems. You're limited by wiring designed for a different era. **Warning signs your wiring needs attention:** Frequent blown fuses or tripped breakers, discoloured sockets or switches, burning smells, flickering lights, round-pin sockets, lack of earthing on metal fittings, or a fuse box with rewirable fuses instead of modern MCBs. Our Process ## Our Rewiring Process A house rewire is a significant project. Our systematic approach ensures quality work, clear communication, and minimal disruption to your home life. 01 1–2 hrs ### Survey & Quote We conduct a thorough survey of your property, assess the existing installation, discuss your requirements, and provide a detailed fixed-price quote with no hidden costs. 02 1–3 days ### Planning We plan cable routes, socket and switch positions, and schedule the work to minimise disruption. For occupied homes, we can work room-by-room to maintain livability. 03 2–4 days ### First Fix We run all new cabling through floors, walls, and ceilings. This phase involves lifting floorboards and chasing walls — we protect your home throughout. 04 1–2 days ### Second Fix We install new sockets, switches, and light fittings. Your new consumer unit is fitted and all circuits are connected. 05 2–3 hrs ### Test & Certify Every circuit is thoroughly tested. You receive an Electrical Installation Certificate and your work is registered with Building Control. Benefits ## Benefits of a Modern Rewire A quality rewire isn't just about compliance — it transforms how you use your home, protects your family, and adds genuine value to your property. ### Full Regulatory Compliance Your rewire meets all current IET Wiring Regulations (BS 7671:2018+A2:2022). We register the work with Building Control and provide certificates for your records. ### Increased Property Value A modern electrical installation is a major selling point. Buyers and surveyors look for evidence of recent rewiring — it removes a significant concern from property transactions. ### Capacity for Modern Living Old wiring wasn't designed for today's electrical demands. A rewire gives you the circuits, sockets, and capacity to power modern appliances, home offices, and EV chargers. ### Enhanced Safety Replace deteriorating rubber and lead-sheathed cables with modern PVC-insulated wiring. RCD protection on all circuits provides life-saving protection against electric shock. ### Minimal Disruption We work efficiently and respectfully in your home. For occupied properties, we can phase the work room-by-room, maintaining access to essential facilities throughout. ### Future-Proof Installation We install additional capacity for future needs — spare ways in your consumer unit, cabling for planned extensions, and infrastructure for smart home integration. ## Types of Rewiring We Provide Not every property needs a complete rewire. We offer solutions ranging from targeted upgrades to full replacements, tailored to your property's condition and your requirements. ### Full House Rewire Complete replacement of all wiring throughout your property. Includes new consumer unit, all circuits renewed, new sockets, switches, and light fittings (or reconnection of existing). Essential for properties with original pre-1980s wiring showing deterioration. ### Partial Rewire Replacement of specific circuits or areas while retaining sound existing wiring. Suitable for properties where some circuits have been updated but others remain outdated, or where only certain areas need attention. ### Consumer Unit Upgrade Replacement of your fuse box with a modern [consumer unit](/services/consumer-units) featuring RCD protection. Can often be done without full rewiring if your existing cables are in good condition. Significantly improves safety without the disruption of a complete rewire. ### Extension and Loft Conversion Wiring New electrical installations for extensions, loft conversions, and garage conversions. We design circuits that integrate with your existing installation and meet Building Regulations requirements. ### Additional Circuits Adding circuits for specific needs: dedicated cooker circuits, [EV charger installations](/services/ev-charger-installation), home office circuits, or additional ring mains for socket capacity. These additions can often be made without disturbing the rest of your installation. Signs You Need This ## Signs Your House Needs Rewiring Most properties built before the late 1980s are now overdue an upgrade. Spot the warning signs early — they get more expensive the longer you leave them. Properties over 25–30 years old without a documented rewire should have an EICR before exchange of contracts — buyers' surveyors flag this as standard. - Round-pin sockets, brown bakelite switches or fabric-covered cable on view - Your fuse box still uses rewirable fuses rather than modern MCBs / RCBOs - Frequent breaker trips — especially when the kettle, oven or shower runs - Sockets that feel warm, look scorched or have cracked faceplates - Lights that flicker, dim or buzz when other appliances switch on - No earth wire visible at metal sockets, lights or your boiler - A recent EICR returned C1 or C2 codes you haven't yet rectified - You're planning a kitchen, extension, loft conversion or EV charger install Indicative Pricing ## House Rewiring Price Guide Honest indicative ranges by property size.

A full rewire is a big decision. Here's how we make sure it doesn't become a nightmare. ### "I can't afford to move out for a fortnight." You don't need to. We work room-by-room in occupied homes, leaving you with power, heating and a working kitchen overnight. Most clients stay in the property for the whole job. ### "The mess and dust will wreck my decor." We dust-sheet every room, use vacuum-attached chasers to cut walls, and lift floors carefully so boards go back down. We can also recommend trusted plasterers and decorators for making good. ### "I'm worried about hidden costs creeping in." Your survey produces a written, fixed-price quote covering every cable, accessory and consumer unit. If we hit something genuinely unforeseen — like asbestos in a wall — we stop, explain and re-quote in writing before continuing. ### "How do I know the work is actually compliant?" Every rewire is tested to BS 7671, certified with an Electrical Installation Certificate, and notified to Building Control under our NICEIC registration. You receive the paperwork your solicitor and insurer will want to see.
