What is house rewiring?

House rewiring involves replacing unsafe, outdated or overloaded electrical systems throughout your home.

This can include new wiring, sockets, switches, lighting circuits, earth bonding, and consumer unit upgrades.

House rewiring is usually needed when:

• Your home is over 25–30 years old
• You experience frequent fuse trips or flickering lights
• Sockets spark or feel warm to the touch
• There’s a burning smell or visible cable damage
• You’re renovating and need to bring electrics up to modern standards

Benefits of rewiring your home

• A safer electrical system that reduces fire and shock risks
• Enables more sockets and modern appliances
• Improves energy efficiency and compatibility with smart tech
• Helps meet current electrical regulations (18th Edition)
• Increases property value and appeal to buyers

Full vs partial house rewiring

Full rewire

A comprehensive replacement of all wiring, sockets, lighting circuits and the consumer unit.

Best for: older properties, major renovations, homes with obvious electrical faults.

Partial rewire

Focused on specific rooms or circuits (e.g., kitchen, extension, or lighting).

Best for: recent renovations, isolated safety issues, upgrading high-demand areas.

If you’re unsure which you need, an electrician can carry out an electrical installation condition report (EICR) to assess safety and recommend the right approach.

Expect noise, dust, temporary power shutdowns, and furniture being moved around.

Many homeowners choose to stay elsewhere during the messiest stages — especially for full rewires.

Longevity is influenced by:

• Load demand (e.g., EV chargers, electric heating)
• Routine electrical inspections (recommended every 5–10 years)
