House Rewire (Full Rewiring) in Redbridge

About house rewire (full rewiring) in Redbridge

A full rewire involves replacing all the electrical wiring, accessories, and the consumer unit in a property. Every circuit is stripped back and replaced with modern twin-and-earth cable, new sockets and switches are fitted, and a new 18th edition consumer unit is installed. The earthing and bonding system is brought up to current standards. This is the most comprehensive electrical upgrade you can carry out and is typically needed in properties with wiring over 25-30 years old, or where an EICR has identified widespread deterioration.

Old wiring deteriorates over time. Rubber-sheathed cable (common pre-1960s), lead-sheathed cable, and early PVC cable can become brittle, lose insulation resistance, and develop faults. Properties with old wiring are at significantly higher risk of electrical fires and electric shock. If your EICR returns a C1 (danger present) or multiple C2 (potentially dangerous) codes, a full rewire may be the only practical solution. It is also often the most cost-effective approach when buying a property that needs major renovation.

• Part P of the Building Regulations (Approved Document P): A full rewire is notifiable electrical work. All new circuits must be designed, installed, tested, and certified by a registered electrician, or inspected by Building Control.
• BS 7671:2018+A2:2022 (IET Wiring Regulations, 18th Edition): The national standard governing all aspects of the installation — cable sizing, circuit protection, earthing, bonding, accessory heights, and special location requirements (bathrooms, kitchens).
• Approved Document B (Fire Safety) — Smoke and Heat Alarms: When carrying out a full rewire, smoke alarms must be upgraded to meet current standards: interconnected mains-powered alarms with battery backup on every storey, plus heat detectors in kitchens.
• BS 5839-6 — Fire Detection in Dwellings: Specifies the grade and category of fire detection required in domestic properties. A Grade D1 Category LD2 system (mains-powered, interconnected, covering escape routes and high-risk rooms) is standard for a full rewire.
