What Is the Rewiring Cost for a 3-Bedroom House in the UK?

The cost of rewiring a 3-bedroom house in the UK can vary depending on several factors, including the complexity of the installation, the condition of the existing wiring, material quality, and regional labor rates. Here’s a detailed breakdown of the costs and considerations involved in rewiring a 3-bedroom house:

Factors Influencing the Cost

  1. Scope of Work
    • Full Rewiring: Involves replacing all wiring, sockets, switches, and the consumer unit. This is more comprehensive and generally more expensive.
    • Partial Rewiring: Only specific areas of the house, such as the kitchen or a single floor, are rewired. This is less extensive and thus lower in cost.
  2. Condition of Existing Wiring
    • Accessibility: Easier access to existing wiring, such as through loft spaces or underfloor voids, can reduce labor time and cost.
    • Old Wiring: Properties with very old or complex wiring systems may require more time and effort to upgrade.
  3. Quality of Materials
    • Standard Components: Using standard wires, sockets, and switches.
    • High-End Components: Opting for higher-quality or designer components can increase the overall cost.
  4. Additional Work
    • Upgrading Consumer Unit: Often involves upgrading the consumer unit (fuse box) to modern standards for safety and compliance.
    • Adding Circuits: Adding extra circuits for modern electrical demands, such as charging points or smart home systems.
  5. Labor Costs
    • Regional Differences: Labor rates can vary significantly, with urban areas, particularly London, typically having higher rates than rural areas.
  6. Inspection and Certification
    • Certification Costs: After rewiring, electrical testing and certification are necessary to ensure compliance with the IET Wiring Regulations (BS 7671).

Typical Costs

  1. Full Rewiring Cost for a 3-Bedroom House
    • Standard Rewire: £3,000 - £5,000
    • High-End Rewire: £5,000 - £7,000
  2. Additional Costs
    • Upgrading Consumer Unit: £400 - £700
    • Inspection and Certification: £150 - £300
    • Plastering and Making Good: £300 - £1,000, depending on the extent of the work required to repair walls and ceilings after rewiring.

Breakdown of Costs

  1. Labor Costs
    • Hourly Rates: £40 - £60 per hour, depending on the region and the electrician’s experience.
    • Total Labor: Typically accounts for around 50-60% of the total cost.
  2. Materials
    • Wiring and Cables: £500 - £1,000
    • Sockets and Switches: £200 - £500, depending on the number and quality.
    • Consumer Unit: £100 - £500, depending on the type and brand.
  3. Additional Components
    • Light Fittings: £50 - £200
    • Speciality Fixtures: £100 - £300 (e.g., smart home systems or designer outlets)

Steps for Accurate Estimation

  1. Professional Assessment
    • Thorough Inspection: A qualified electrician should conduct a thorough inspection of the existing wiring to provide an accurate assessment and quote.
    • Detailed Quote: Obtain a detailed quote that includes all potential costs, such as labor, materials, testing, certification, and any additional work required.
  2. Obtain Multiple Quotes
    • Comparison: Get quotes from multiple electricians or electrical contractors to compare prices and services offered.
    • Transparency: Ensure all quotes are detailed and provide a clear breakdown of costs.
  3. Check Credentials
    • Qualified Electricians: Hire electricians registered with a competent person scheme such as NICEIC, NAPIT, ELECSA, or STROMA Certification to ensure compliance with safety and regulatory standards.
    • Experience: Verify the electrician’s experience and track record in conducting rewiring projects.
  4. Plan and Budget
    • Assess Needs: Determine the extent of the rewiring required and prioritize essential areas if on a tight budget.
    • Budgeting: Plan and set a budget for the project, considering all possible costs, including additional work for making good walls and ceilings after rewiring.


The cost of rewiring a 3-bedroom house in the UK typically ranges from £3,000 to £5,000 for a standard rewire, and £5,000 to £7,000 for a high-end rewire. Additional costs may include upgrading the consumer unit (£400 - £700), inspection and certification (£150 - £300), and plastering and making good (£300 - £1,000). Understanding the factors influencing the cost, obtaining multiple quotes, and ensuring the work is carried out by qualified electricians are crucial steps in planning and budgeting for a rewiring project. Proper assessment and clear communication with the electricians can help ensure a smooth and compliant rewiring process.
