Do I need a full rewire?

Usually repair and upgrade

• PVC-insulated cable with good insulation resistance results
• Faults limited to accessories, bonding or RCD protection
• A few damaged or undersized circuits that can be replaced individually

Usually rewire

• Rubber or lead-sheathed cable still in use
• Widespread low insulation resistance across many circuits
• No protective conductors on lighting circuits throughout
• Heavy, undocumented alterations that cannot be traced or verified

Partial rewires

Often only one floor or one circuit type, such as lighting, needs replacing. A partial rewire can be timed with redecoration or a void period between tenancies.

An EICR gives you the evidence to decide. Ask the inspector to state clearly whether they recommend repairs, a partial rewire or a full rewire, and why.
