Frequently Asked Questions

How do I know if my house needs rewiring?

Warning signs include old round-pin sockets, fabric or rubber cable insulation, no RCD protection, frequent tripped breakers, and wiring over 25 years old. An EICR test (£150-£300) provides a definitive answer.

Can I live in the house during rewiring?

Usually yes, though expect significant disruption. Electricians work room by room, with power off in sections. Some families stay elsewhere for the first few days.
