That question is one that any homeowner is likely to ask themselves when considering the project, and the answer is – it depends. There’s no one-size-fits-all approach to rewiring a house; every home has its unique challenges and needs, so it’s difficult to provide a precise answer to the question. However, in general, a full rewire can take anything from 2 to 5 days, depending on the size of the property and the complexity of the job.

In this blog post, we’ll discuss the rewiring process in detail, specific to house rewiring.

Planning The Rewiring Process

Rewiring a house is a significant job that should not be taken lightly or rushed. It requires proper planning to ensure a successful outcome. The first step to planning the rewiring process is to create a detailed plan of the electrical system, which includes a complete inventory of all electrical fixtures and components. This plan will form the basis of the entire rewiring project.

Once you have created the plan, you should consult with a qualified electrician to assess your wiring and determine if you need to rewire your house. The electrician will take into account the age of your wiring, the type of wiring and the wear and tear of the electrical components. Based on their assessment, they will be able to advise you on whether you need to rewire your property or not.

Assessing The Existing Electrical System

Before any work can commence, it is crucial to assess the existing electrical system thoroughly. The electrician will need to evaluate the condition of the wiring, confirm the location of all the electrical outlets and equipment, and assess whether there are any areas of the system that are overloaded or have suffered damage.

The size of the property plays a significant role in the type of system you will need. Large homes need more powerful systems that will be able to handle larger appliances and more significant loads. Once the electrician has assessed the electrical system, they will offer advice on what type of wiring and systems will best suit your needs.

Calculating The Required Materials And Labour

Once you have a plan in place and your electrical system has been assessed, the electrician will provide a detailed estimate of the costs involved in the rewiring process. This will include the price of the required materials and labour costs. The price of materials will vary based on the size of your property, the type of wiring and system required, and the quality of the components used.

When calculating the labour costs, the electrician will consider the complexity of the rewiring project, the time required to complete the tasks and the number of workers needed to accomplish the job. You need to be familiar with the cost involved before beginning the rewiring process to avoid surprises and ensure that you don’t overspend.

Gaining Necessary Permits And Approvals

A lot of areas require permits before any electrical work can be done on a property. Some states insist on applying for a permit for electrical rewiring. Permits ensure that the work is completed safely and complies with the local codes and regulations. Obtaining permits will require an additional fee, so it’s essential to include the cost in your budget.

It is the electrician’s responsibility to obtain all the necessary permits before starting work on your property. The electrician should also be familiar with the local regulations, so they can ensure that the rewiring project is completed to code.

Removing Old Wiring And Fittings

The next step is to remove any old wiring and fittings that you no longer need. The electrician will carefully dismantle all old fixtures while saving any components that can be reused. The electrician will then dispose of any unusable wiring and fixtures safely.

Once all the old wiring and fittings have been removed, your electrician will start the rewiring process. Electricians may work from the roof space down or from the bottom of the house upwards to minimize disruption to your daily activities.

Installing New Wiring, Fixtures And Circuit Breakers


After the old fitting and wiring have been removed, the electrician will begin installing the new layout. They will install the new wiring and fit all new outlets, light switches, junction boxes, and circuit breakers.

The electrician will work with you to ensure that the new system is designed to meet your needs and allow you to use all of your electrical appliances. The fixtures will be installed to comply with the local regulations and comply with the requirements of your homeowners’ insurance.

Testing And Certification

Once the rewiring is complete, the electrician will test everything to ensure that it is running correctly. The electrician will conduct a thorough inspection of the entire system, checking all the circuits and components to ensure that they are working as designed.

If everything is working correctly, the electrician will provide certification that confirms the electrical work on the property has been completed to the required standard. This certification is crucial, especially if you decide to sell your property in the future.

Cleaning And Finishing

Finally, the electrician will clean up the work area and remove any debris from the rewiring project. They will dispose of any old wiring and fixtures safely, leaving you with a clean and tidy home.

Future Maintenance Requirements

It is essential to maintain your electrical system properly to ensure that it continues working correctly and safely. Your electrician will provide advice on the best way to maintain your new electrical system, including tips on when to replace any old components, outlets and light switches and how to look out for any potential issues before they become a significant problem.

Rewiring a house is a significant undertaking that requires careful thought, planning, and execution. The entire process can take anything from 2 to 5 days, depending on the size of your property and the complexity of the job. However, with careful planning and the help of a qualified electrician, you can have peace of mind knowing that your new system is safe, efficient, and designed to meet your electrical needs.
