How Long Does It Take To Rewire a House?


after the job of a light rewiring in houseWhen looking into the duration of time it takes to rewire a house, the size of the house and how many rooms it has must be taken into consideration. An average house has 3-4 rooms.

Full rewiring service will take 7 days to complete. However, the amount of time it takes to complete the rewiring depends on how many new components you need installing.

Allow us to dive into greater detail in regards to the process of rewiring a house.


  1. Assessment and Planning: The initial assessment and planning phase typically involves a licensed electrician visiting your home to evaluate the existing electrical system, discuss your requirements, and determine the plan of the project. This phase may take a few hours to a couple of days, depending on the complexity of the house and the thoroughness of the assessment.


  1. Preparation and Material Procurement: Once the assessment is complete, the electrician will create a detailed plan and prepare a materials list. This phase includes gathering the necessary wiring materials, fixtures, and other components required for the rewiring. The time required for material procurement can vary based on availability and ordering timelines, usually ranging from a few days to a week.


  1. Wiring and Installation: The actual rewiring work begins with the electricians removing the old wiring, replacing it with new wiring, and installing new outlets, switches, and other necessary components. This phase can take anywhere from a few days to several weeks, depending on the size of the house, the complexity of the electrical system, and the number of electricians working on the project.


  1. Additional Upgrades and Modifications: If you’ve opted for additional electrical upgrades or modifications, such as installing a new electrical panel or incorporating smart home features, these will be integrated into the rewiring process. The time required for these upgrades will depend on their complexity and can add a few days to the overall project timeline.


  1. Testing, Inspection, and Finalisation: After the rewiring work is complete, the electricians will conduct thorough testing to ensure the proper functioning of the electrical system. They will also schedule any necessary inspections to ensure compliance with local building codes and regulations. The time required for testing, inspection, and finalisation can range from a few hours to a couple of days.


While the duration of rewiring a house can vary, it’s important to allocate sufficient time for planning, execution, and necessary inspections.

To get a more accurate estimate of the timeline for your specific project, consult with an experienced electrician who can assess your house and provide a detailed timeline based on its unique requirements.

Proper planning and professional execution are key to ensuring a successful and efficient rewiring project.
