About house rewire (full rewiring) in Kingston upon Thames

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.

Regulations & standards

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.

House Rewire (Full Rewiring) FAQs

How do I know if my house needs a full rewire?

The most reliable way is to get an EICR (Electrical Installation Condition Report). If it returns multiple C1 or C2 codes, or identifies old cable types (rubber, lead, or early PVC), a rewire is likely needed. Visible signs include round pin sockets, brown Bakelite switches, fabric-covered cable, and a rewirable fuse box.

Can I live in the house during a rewire?

It is possible but uncomfortable. There will be no power during first fix (typically 3-7 days), significant dust from chasing walls, and floorboards will be lifted. Many people stay elsewhere during first fix and return once power is restored. Discuss this with your electrician beforehand.

Does a rewire add value to my property?

Yes. A new electrical installation with a valid EIC is a selling point and removes a significant concern for buyers and mortgage surveyors. It also makes the property eligible for standard home insurance without electrical exclusions. The investment typically pays for itself in property value.

Can I do a partial rewire instead?

Sometimes. If the wiring is generally in good condition but one or two circuits need replacing (e.g., an old lighting circuit), a partial rewire can be more cost-effective. However, if the overall wiring is old and deteriorating, a full rewire is usually more economical in the long run than doing it piecemeal.

Will I need to redecorate after a rewire?

Yes. Cables are chased into walls, which then need making good with plaster. You will need to redecorate every room where chasing has taken place. Budget for plastering and decorating costs — this can add £1,000-3,000 depending on the size of the property.

How long does a rewire last before the next one is needed?

A properly installed rewire using modern materials should last 25-40 years. The IET recommends an EICR every 10 years for domestic properties (or at change of occupancy) to verify ongoing condition. With regular testing and minor maintenance, modern wiring can last well beyond 30 years.
