Electrical installation costs in Nigeria vary widely based on the type of building, its size, and the quality of materials used. In 2025, inflation, exchange rates, and rising demand for copper cables have pushed prices higher, making budgeting essential for homeowners and contractors.
1. Materials
Electrical materials usually account for 60–70% of total installation costs. Common components include:
•Cables and Wiring: High-quality brands like Coleman, Nigerchin, and Cutix cost ₦450–₦750 per metre for 2.5mm² twin and earth cables, while 4mm² cables for high-power circuits range from ₦900–₦1,300 per metre.
•Switches and Sockets: From budget types at ₦1,500–₦2,000 per unit to premium Schneider or ABB models at ₦5,000–₦10,000.
•Distribution Boards (DBs): ₦25,000–₦60,000 depending on capacity and brand.
•Conduits and Accessories: 20mm or 25mm PVC conduits cost ₦350–₦600 per length.
•Lighting Fixtures: Basic LED bulbs cost ₦1,500–₦2,500; designer fittings start at ₦10,000+.
Estimated Material Cost for a 3-Bedroom Flat: ₦1.8 million – ₦2.5 million (mid-range quality).
2. Labor
Labor costs depend on the project complexity and electrician’s expertise:
•Wiring labor: ₦150,000 – ₦300,000 for a 3-bedroom flat.
•Installation of lighting/sockets: ₦500–₦1,500 per point.
•Testing and commissioning: ₦30,000–₦50,000.
3. Factors Influencing Cost
