How to pay less

Combine a rewire with other building work so walls are only opened once.
Agree who does the plastering and decorating before starting.
Ask for a fixed price after a survey, not an estimate over the phone.

Before you hire

Ask for a competent person scheme registration and an Electrical Installation Certificate when the work ends.
Ask who notifies building control and who arranges the plastering and decorating.
Ask for a quote that lists the number of sockets, switches, lights and circuits.
Ask whether you need to move out while the work happens.
Ask how they protect floors and furniture.

💬 Questions about rewiring costs

How do I know if I need a rewire?

Signs include old rubber or fabric cables, round-pin sockets, a very old fuse box, scorch marks or regular tripping. An electrician can check with an inspection.

Does a rewire need certification?

Yes. A rewire is notifiable under Part P of the Building Regulations in England, so ask your electrician for the certificate when the work is finished and keep it.

Can I stay at home during a rewire in London?

Often, yes, but the power goes off in stages and there is dust and noise. Many people stay with friends for a few days. Ask the electrician about the plan.

Does the price include redecorating?

Usually not. A rewire involves cutting into walls and floors, so plastering and painting are often separate. Ask each electrician what is included.
