Signs worth investigating
Rubber or fabric-covered cable, no earth at lighting points, an old fuse board or repeated faults are reasons to inspect, not automatic proof that a rewire is required.
Full and partial house rewiring
Rewiring replaces a property's fixed wiring, accessories and circuit protection. A survey establishes whether a full rewire, a partial rewire or targeted remedial work is the right answer before any price or timescale is agreed.
House rewiring price
Rewiring is priced after a survey. The published rate or starting price below is a guide until the property has been seen.
- Property size, circuit count, access, finishes and your own choices all change the price.
- Making good, decoration and any building work are separate unless the quote includes them.

Check whether a rewire is actually needed
Age alone does not mean a property needs rewiring. Inspection and testing should establish the real condition first.
Full rewire
All fixed wiring, accessories and circuit protection are replaced. This is the most disruptive option and normally suits a property being renovated or stripped back.
Partial rewire
Only the circuits that testing shows are unsuitable are replaced. This can be right where earlier work has already renewed part of the installation.
Targeted remedial work
Sometimes an inspection shows specific defects that can be corrected without rewiring. The report should explain what the evidence supports.
What a rewire covers
The quote records the agreed circuits, accessories, consumer unit and the boundary between electrical work and building work.

How a rewire runs
The process differs a great deal between an occupied home and an empty property, so agree the plan before booking.
- 01
Survey and agree the scope
The electrician inspects and tests the existing installation, then explains whether a full rewire, partial rewire or remedial work is supported by the findings.
- 02
Plan the circuits and positions
Agree the circuit schedule, socket and switch positions, lighting points and consumer unit location before first fix starts.
- 03
First fix
Cable routes are formed, back boxes fitted and new cabling run. This is the dusty, disruptive stage and normally needs rooms cleared.
- 04
Second fix
Accessories, lighting points and the consumer unit are fitted and connected once the surfaces are ready.
- 05
Test, certify and hand over
The installation is inspected and tested, the board is labelled, and the certificate and notification are provided.
What you receive
The handover records the new installation and anything left outside the agreed scope.
- Replaced wiring and accessories
- The agreed circuits, sockets, switches and lighting points are installed and connected.
- New consumer unit
- The board is fitted with the agreed circuit protection and clearly labelled.
- Certificate and notification
- You receive the Electrical Installation Certificate and the Building Regulations record where applicable.
- A clear making-good position
- The quote states what the electrician makes good and what is left for a plasterer or decorator.

House rewiring questions
What to know before committing to a rewire.
Does my house need rewiring?+
Not necessarily. An inspection and test of the existing installation should establish its condition. Age, cable type and previous work all matter, but the report should explain what the evidence supports.
How much does a rewire cost?+
It depends on the property size, number of circuits, access, finishes and the accessories you choose. A survey is needed before any realistic price can be given.
How long does a rewire take?+
It varies with the property and whether it is occupied. The electrician should give an expected duration after the survey rather than a standard figure.
Can I stay in the house during a rewire?+
Often yes, though it is disruptive. Rooms are worked on in stages, power is off for periods and floors or walls may need access. An empty property is usually quicker.
What are first fix and second fix?+
First fix is running the new cables and fitting back boxes before surfaces are finished. Second fix is fitting the sockets, switches, lighting points and consumer unit afterwards.
Will the walls and floors be damaged?+
Some chasing, floorboard lifting and drilling is normally unavoidable. The quote should state how much making good is included and what is left for other trades.
Will the power be off?+
Yes, for parts of the work. The electrician should explain when circuits will be off and what temporary supplies, if any, can be arranged.
Is rewiring notifiable work?+
In England, a rewire is notifiable building work. The electrician should explain how the work will be certified and notified before it starts.
What certificate will I get?+
You should receive an Electrical Installation Certificate covering the completed work, plus the relevant Building Regulations compliance record.
