House Rewiring Cost in Ireland (2026): Complete Guide

Updated June 2026 7 min read

Rewiring a house is one of the most significant upgrades you can undertake as a homeowner in Ireland. Not only is it crucial for safety—especially in older properties with outdated wiring—but it also prepares your house for today’s range of appliances and future-proofs it for smart home technology. As of 2026, electrical compliance and quality have never been more important.

But what should you realistically expect to pay? The typical cost to rewire a three-bedroom semi-detached house in Ireland ranges from €12,000 to €13,000 in Dublin and about €8,500 to €11,500 elsewhere. For smaller apartments, you might see prices from €7,000, and for large detached homes, the bill can rise to €25,000 or more. These prices include VAT at 13.5%, a new consumer unit, comprehensive testing, and a Safe Electric completion certificate from a registered electrician.

Several factors influence this investment, such as the size and layout of your property, the age and condition of the existing wiring, and any modern features you want to introduce (like additional outlets or smart systems). While there aren’t SEAI grants specifically for rewiring, you may be able to combine the work with other energy and insulation upgrades to reduce your overall expenses.

What’s Included in a Full House Rewire?

A full house rewire involves installing new wiring throughout your property. This brings your home up to current National Wiring Rules (ET101) and ensures safe compatibility with modern electrical demand. Here’s what you can typically expect:

  • All wiring replaced—including sockets, switches, and lighting circuits
  • New consumer unit/fuse board (distribution board)
  • Upgrade or addition of earth bonding
  • New or additional sockets, switches, and light fittings as needed
  • Full safety testing after installation
  • Safe Electric certification and Building Regulations compliance

Key Factors Affecting Rewiring Costs

Several important factors play a role in your final rewiring bill:

  • Property size and layout: More rooms mean more cabling, outlets, and work.
  • Age and condition of the existing wiring: Older homes (pre-1980) usually require extra attention.
  • Ease of access: Difficult attic spaces or confined wall cavities increase labour time.
  • Upgrades and extras: More outlets, USB sockets, kitchen upgrades, or integrated smart tech drive costs higher.
  • Region: Labour is pricier in cities such as Dublin, compared to places like Kerry, Louth, or Galway.

Regional Price Differences Across Ireland

Your location does impact the price. Demand for qualified electricians and higher living costs in Dublin push prices up. For example, rewiring a standard three-bed in the capital generally falls into the €12,000–€13,000 bracket, while similar work in counties like Kerry comes in at €8,500–€11,500. Coastal and rural areas may offer greater availability and less competition for tradespeople, which helps control costs.

Combining Electrical Upgrades With Other Home Improvements

Although there’s no dedicated SEAI grant for wiring, you may be able to bundle your project with insulation or renewable energy upgrades. This approach can be both disruptive and cost-effective:

  • Attic insulation: up to €2,000 grant available
  • Cavity wall insulation: up to €1,800 for detached houses
  • Heat pump installation: up to €12,500 in grants, which often necessitate additional electrical work

If you’re already opening up walls or ceilings for rewiring, it may be the ideal moment to future-proof with these improvements. Always check the latest SEAI grant options before committing to any project.

Regulations, Certification & Planning Tips

All major electrical work in Ireland must be carried out by a Safe Electric-registered contractor and meet current Building Regulations and Wiring Rules. At the end of the works, you should receive a certificate confirming compliance, which is vital for your property records and legal safety.

  • Get multiple written quotations from registered electricians.
  • Budget for potential additional costs such as making good (plastering and painting) and possible short-term accommodation if staying in the house isn’t feasible.
  • Plan your timing – scheduling during less busy periods may yield better prices and faster completion.
