What Happens During a Full House Rewire?

A full house rewire is a major electrical project, and understanding the process helps reduce uncertainty.

While every property is different, most rewires follow a clear sequence of stages.

If you are considering rewiring, you can find full details of our House Rewiring services in Altrincham.

Stage 1: Initial Inspection and Planning

Before work begins, the installation is assessed to confirm scope.

This includes:

Reviewing the existing wiring
Agreeing socket and lighting positions
Planning circuit layout
Confirming specification

Clear planning prevents costly changes later.

Stage 2: First Fix

The first fix is the main installation phase.

This typically involves:

Removing old wiring
Lifting floorboards
Chasing cables into walls
Running new circuits throughout the property
Installing back boxes for sockets and switches

At this stage, no faceplates are fitted and walls may be open.

How Disruptive Is First Fix?

Rewiring is inherently disruptive. Expect:

Dust and noise
Temporary power outages
Floorboards lifted
Wall chasing where required

In empty properties, the process is significantly more straightforward.

Stage 3: Consumer Unit Installation

A new consumer unit is normally installed as part of the rewire.

This includes modern RCD or RCBO protection in compliance with current regulations.

Stage 4: Second Fix

Once walls are made good and plastered, the second fix involves:

Fitting sockets and switches
Installing light fittings
Connecting circuits at the consumer unit
Labelling and identification

Stage 5: Testing and Certification

After installation, the entire system is:

Tested for insulation resistance
Checked for correct polarity
Verified for earth continuity
Tested for fault disconnection times

You should receive:

An Electrical Installation Certificate
Part P Building Regulations notification (for domestic properties)

How Long Does a Full Rewire Take?

Most standard houses take between 5 and 10 working days, depending on size and complexity.

Larger or more complex properties may take longer.

Can You Stay in the Property?

It is sometimes possible, but disruption should be expected.

Many homeowners choose to vacate during full rewires, particularly where significant plastering is involved.

What Happens After Completion?

Once complete, the property will have:

Modern, compliant wiring
Improved electrical safety
Capacity for modern appliances and future upgrades

A properly completed rewire provides decades of reliable service.
