What Is a House Rewire and When Do You Need One?
A house rewire involves replacing all or part of the electrical wiring, cables, sockets, switches, and consumer unit in your property. It brings your home's electrical system up to current BS 7671 (18th Edition) wiring regulations.
Properties built before 1980 almost certainly have wiring that no longer meets modern safety standards. Rubber-insulated cabling, lead-sheathed wiring, and outdated fuse boxes are fire risks that no amount of patching can fix.
A full rewire is typically needed when the existing wiring is over 25-30 years old, when you are extending or renovating, when an EICR reveals unsatisfactory results, or when you are converting a property for rental compliance.
ElectroSafe handles both full house rewires and partial rewires. A partial rewire addresses specific circuits or areas without replacing the entire system — ideal when only part of the installation is outdated or when budget requires a phased approach.
The Real Cost of Living with Outdated Wiring
Electrical fires cause over 14,000 house fires in the UK each year. The leading cause is old, degraded, or improperly installed wiring. If your home has wiring from the 1960s or 1970s, the insulation around those cables is deteriorating right now.
Rubber and fabric-insulated cables become brittle over time. When insulation cracks, live conductors can contact earth paths, other cables, or flammable materials. The result is an arc fault — a sustained electrical spark that generates temperatures exceeding 3,000°C.
Outdated consumer units with rewirable fuses offer none of the protection that modern RCDs provide. An RCD trips in 30 milliseconds when it detects a fault — saving lives. A rewirable fuse does not offer this protection.
Beyond fire risk, old wiring cannot support modern electrical loads. Running a household on circuits designed for a few light bulbs and a radio creates chronic overloading, voltage drops, flickering lights, and premature appliance failure.
Insurance companies increasingly refuse claims where electrical faults were a contributing factor and the wiring was known to be outdated. A rewire is not just a safety investment — it protects your home insurance validity.

Every rewire is backed by our comprehensive guarantee. If any issue arises from our workmanship within 12 months, we return and resolve it at no cost.
House Rewiring: Materials, Methods, and What to Expect
A modern house rewire uses Twin & Earth (T&E) PVC-insulated cables throughout. The most common sizes are 1.0mm² for lighting circuits, 2.5mm² for ring main socket circuits, 6.0mm² for cooker circuits, and 10.0mm² for electric shower circuits.
Cable routing depends on your property type. In houses, cables typically run under floorboards and through ceiling voids. In flats and solid-floor properties, cables may need to be chased into walls or run in surface-mounted trunking.
The consumer unit is the heart of your electrical system. We install 18th Edition compliant units with RCBOs (Residual Current Breaker with Overcurrent protection) on every circuit — providing individual circuit protection that exceeds minimum regulations.
Socket and switch positions are planned with you before installation begins. We recommend USB-integrated sockets in kitchens and living areas, dimmer switches where appropriate, and sufficient socket density to eliminate extension lead dependency.
For period properties, we take extra care to preserve original features. Cable routes are planned to avoid visible surface runs wherever possible, and we use heritage-style switches and sockets when requested.
Partial rewires address specific deficiencies without replacing the entire system. Common partial rewire scenarios include upgrading a consumer unit, adding circuits for a new kitchen or bathroom, replacing a single floor's wiring, or adding outdoor circuits.
Commercial rewiring follows the same BS 7671 standards but with additional considerations for three-phase supplies, higher current demands, emergency lighting integration, and fire alarm system compatibility.
After completion, we conduct a full suite of tests including continuity, insulation resistance, earth fault loop impedance, RCD trip time, and polarity checks. Results are documented on an Electrical Installation Certificate (EIC) and registered with your local building control through .
