What does it cost to rewire a 1930s two-up, two-down?

Rewiring a 1930s two-up, two-down house can be a costly and complex undertaking, according to quantity surveyor Shay Lally, who specializes in home renovation projects. A recent inquiry from a homeowner seeking to understand the financial implications of such a task revealed that the process involves far more than just hiring an electrician. The cost of rewiring a property built during the early 20th century ranges from approximately €17,864.90 to €20,702.40, excluding additional expenses related to redecoration and upgrades. The process begins with cutting off the main electricity supply and installing a temporary power source to ensure safety during the rewire. This initial step alone costs around €340.50. Next, the existing wiring must be stripped out, which includes removing all the old cables. This phase is estimated to cost €851.25. Following that, the installation of new electrical components takes center stage. For a typical 1930s house, installing 70 points, such as sockets, switches, and lighting fixtures, at a rate of €158.90 per point totals €11,123.00. Additional costs include the installation of six smoke detectors at €158.90 each, totaling €953.40, and upgrading the fuse board, which comes in at €1,418.75. Other essential elements include the supply of heating controls, costing €454.00, and testing and certification of the entire electrical system, another €454.00. The physical modifications required to accommodate the new wiring add significantly to the overall expense. Wall chasing, which involves cutting into walls to route cables, is priced between €1,135.00 and €2,270.00, depending on the number of sockets and switches being installed. Patching the walls after chasing is similarly variable, ranging from €1,135.00 to €2,837.50. These figures represent the core rewire costs. However, homeowners should be prepared for further expenditures once the electrical work is complete. Redecoration is a crucial yet frequently underestimated aspect of the project. Painting the interior could cost anywhere from €5,000 to €8,500, depending on the scope of the work and materials used. Flooring replacements or repairs might add another €1,500 to €9,500 to the total bill. Additional considerations arise when choosing non-standard electrical fittings. While the base cost calculation assumes standard white fixtures, opting for decorative light fittings or antique-style switches requires the homeowner to purchase these items separately, as they are not included in the initial estimate. These choices can influence both the aesthetic and the final price tag of the renovation. The complexity of rewiring a historic home underscores the importance of planning and budgeting. Unlike modern homes, older properties require careful handling due to their unique structural features and potential hidden challenges. The process demands coordination among multiple tradespeople, including electricians, builders, and plasterers, each contributing to the overall cost. For homeowners contemplating a similar project, understanding the detailed breakdown of costs is vital. The initial investment in rewiring is substantial, but it ensures the home meets current electrical standards and enhances its safety and functionality. As with any major renovation, thorough research and professional consultation are recommended to navigate the complexities and avoid unexpected expenses.
