How Much Does Electrical Wiring Cost in Nigeria? (2025 Guide)
Electrical wiring installation is one of the most important investments in any building project. Whether you are completing a new house in Ondo State, refurbishing an office in Lagos, or adding extensions to an existing property, understanding the true cost of wiring helps you plan your budget and avoid being overcharged. This guide by Rehoteq Technologies — certified electrical engineers based in Okitipupa — breaks down all cost factors for 2025.
The Four Types of Electrical Wiring in Nigeria
- Conduit Wiring: The most common type in Nigeria. PVC conduit pipes are embedded inside walls or run along ceilings. This method hides all wires, gives a clean professional finish, and protects cables from physical damage. It is slightly more expensive than surface wiring but far more durable and aesthetically superior.
- Surface Wiring: Cables are clipped directly onto walls using cable clips or cleats. This is the fastest and cheapest installation method — ideal for temporary setups, workshops, or rural structures. It leaves cables exposed but is easy to repair and modify.
- Trunking / Casing Wiring: Cables are run through rectangular PVC trunking (also called raceway or casing) fixed along walls. This gives a neat, professional finish, is easy to maintain, and allows additional cables to be added later. Preferred in office buildings, schools, and commercial premises.
- Automated / Smart Wiring: Standard wiring enhanced with motion sensors, smart switches, programmable timers, remote controls, and energy monitoring systems. This is the premium option — suitable for modern homes, hotels, and high-end offices seeking energy efficiency and convenience.
What Affects Wiring Cost in Nigeria?
- Number of Points: Each socket outlet, light point, switch, or appliance connection is a "point." More points mean more cable, conduit, fittings, and labour time. A typical bedroom has 4–8 points; a sitting room may have 8–14.
- Cable Size and Brand: Standard residential wiring uses 1.5mm² for lighting and 2.5mm² for sockets. Economy brands like Dana or Kabelmetal are cheaper; mid-range brands like Coleman or Vecan offer better quality; premium brands like Nexans or Bicc (now Prysmian) offer the best conductivity and insulation.
- Distribution Board (DB): The DB (also called a consumer unit or fuse box) is the central hub for all circuits. Larger buildings need bigger DBs with more ways (circuit breakers). An 8-way DB with breakers typically costs ₦25,000–₦60,000 installed.
- Labour Rate: Qualified electricians in Nigeria charge between ₦5,000 and ₦15,000 per point, depending on location, job complexity, and experience. Certified electrical engineers (like Rehoteq) include proper earthing, bonding, and code compliance.
- Property Size and Complexity: Multi-storey buildings, long cable runs from DB to remote rooms, or concrete reinforced slabs increase labour time and material length significantly.
Typical Wiring Costs by Property Type in Nigeria (2025)
- 1-bedroom flat (conduit): ₦180,000 – ₦380,000
- 2-bedroom flat (conduit): ₦280,000 – ₦560,000
- 3-bedroom bungalow (conduit): ₦380,000 – ₦780,000
- 4-bedroom duplex (conduit): ₦600,000 – ₦1,400,000
- Office (trunking, per floor): ₦250,000 – ₦700,000
- Smart home (automated): add 40–80% to base conduit cost
Do I Need a Certified Electrician for House Wiring in Nigeria?
Yes — and not just for safety, but for compliance with NEPA/EKEDC regulations. Improperly installed wiring is the leading cause of house fires in Nigeria. A certified electrician will properly size cables for load, install correct circuit breakers, earth the system, and issue a test certificate. Rehoteq Technologies provides certified electrical installation with full earthing systems, test and commissioning reports, and after-service support.
