The cost to rewire a four-bedroom house typically ranges from £5,500 to £8,000, depending on various factors such as the complexity of the wiring, the materials used, and the specific requirements of the home. This process usually takes between 7 to 10 days to complete, as it involves not only replacing old wiring but also ensuring that the electrical system meets current safety standards. Factors that can influence the final cost include the age of the house, the condition of existing wiring, and any additional electrical features that may need to be installed, such as new outlets or lighting fixtures. It is advisable to obtain multiple quotes from licensed electricians to ensure a fair price and to discuss any specific needs or concerns you may have regarding the rewiring project.
