Electrical Installation Cost | How Much Does House Wiring Cost in 2026?

The cost of electrical installation is one of the larger expenses during construction. House wiring cost depends on many factors, so it's worth knowing what affects the price and how to estimate the budget.

Before requesting quotes, prepare at least a basic electrical installation plan and an outline of the distribution board. Installations priced from a clear scope are easier to compare than rough offers based only on square meters.

How Is Electrical Installation Priced?

Electricians most commonly charge:

• Per electrical point: Flat rate for each socket, switch, light fixture.
• Per square meter: Simple method, but doesn't account for installation complexity.
• Fixed project price: Common for whole-house installations.

Factors Affecting Cost

The final amount depends on:

• House area – more rooms = more circuits and cable.
• Number of points – every additional socket means extra cable and labor.
• Standard and equipment – basic installation vs. smart home integration.
• Regional labor rates – prices vary significantly by location.

The biggest pricing swing usually comes from specification creep: more dedicated circuits, premium fittings, surge protection, EV readiness, heat pump power supply, and more complex cable selection.

What Does "Per Point" Include?

It's worth clarifying with the electrician what's included in the price:

• Cable from distribution board to device
• Junction boxes and back boxes
• Labor (chasing, pulling cables)
• Actual devices (sockets, switches) – often quoted separately

Average Costs

Prices vary by region, but typical ranges:

• Per point: $30-80 USD (basic), $60-150 USD (premium)
• Per square meter: $15-40 USD
• Typical house (150m²): $5,000-15,000 USD depending on complexity

How to reduce electrical installation cost without under-designing

• Finalize room layout early, so sockets and switches are not moved during finishing.
• Separate essential circuits from optional upgrades.
• Prepare a realistic appliance list before the electrician starts.
• Use a tool like Electrical Installation Software to estimate materials before collecting quotes.

In Electro Planner, you can generate a complete material list, compare variants, and estimate total cost from the same project used for planning. That makes it easier to compare quotes and avoid underpricing or unnecessary overspecification.
