Rewiring

Removal of old wiring, installation of new cable runs throughout the property, updating socket and switch positions, fitting a new consumer unit, and full testing and certification.

Good to know

Common questions

General guidance about electricians in the UK, not specific to any one business.

What is the difference between a fuse box and a consumer unit?

A fuse box uses replaceable wire fuses that blow when circuits overload. A consumer unit uses circuit breakers that switch off automatically and can be reset. Consumer units are safer and meet modern building regulations.

Can I add sockets to any wall?

Most internal walls can have sockets added, but the cable route must be planned to avoid pipes, structural timbers, and existing services. External walls need extra insulation considerations. An electrician will assess feasibility first.

What should I check before buying an EV charger?

Verify your home has adequate electricity supply (typically 32–40 amps), parking is fixed and dedicated, and the property is suitable for installation. A survey by an electrician confirms whether upgrades to the consumer unit are needed.

Why do electrical appliances need PAT testing?

PAT testing checks that appliance leads, plugs, and earth connections are safe and not damaged. It identifies faulty appliances before they cause electric shock or fire. Businesses are legally responsible for appliance safety on their premises.

How long does a full house rewire typically take?

A complete rewire usually takes 1–2 weeks depending on property size, layout, and whether walls need chasing or the property is empty. Disruption includes plaster chasing, new cable runs, and temporary disconnections during switchover to the new consumer unit.
