Other Factors That Influence Cost

Age and Condition of the Property: If the property is old or the current wiring system is outdated or damaged, it may require additional work to ensure it complies with modern electrical codes.

Type of Wiring: The cost could vary depending on the type of wiring material used, such as standard copper wiring or higher-end materials that may be more durable or energy-efficient.

Additional Work: If you plan to add new light fixtures, extra power points, or upgrade the electrical board, these additions will add to the overall cost.

What is an average cost of house rewiring per square meter?

Based on industry data, you can expect to pay between €32 and €46 per square meter for a full house rewire in Ireland.

Additional Considerations:

Labour Costs: Electricians in Ireland generally charge around €40-€60 per hour depending on experience and location. For a full rewiring job, labour may take anywhere from 3-7 days, depending on the property size and complexity. 

Building Regulations: Rewiring must meet Irish building and electrical codes, so it’s important to hire a qualified electrician. The cost of hiring a certified electrician might be higher but ensures your home is safe and meets legal requirements.

How to measure your rewiring cost for your house?

To measure your rewiring cost for your house, firstly you need to measure your total floor area of your house in square meter and then multiply with €32 and then by €46. This will give you a cost range based on the square meter rate.

Example:

Let’s say your house is 100 square meters: 

€32 x 100 = €3,200 

€46 x 100 = €4,600 

This suggests a rough cost estimate of €3,200 to €4,600 for rewiring your 100 square meter home. 

Important Considerations: 

This is an average: The actual cost can still vary based on the factors I mentioned earlier (complexity, location, etc.).

How Do You Know If a House Needs Rewiring?

To know if you need rewiring, you need to know the signs that tell if a house needs rewiring. The most definitive way to know if your house needs rewiring is to have a comprehensive electrical inspection performed by a qualified and licensed electrician. They can assess the age and condition of your wiring, identify any safety hazards, evaluate your panel’s capacity, and determine if your electrical system meets current building codes and your household’s power needs. This inspection will provide you with a clear professional assessment and recommendations.

How often should a house be rewired in Ireland?

It’s recommended that a house should be rewired in every 25 to 30 years in Ireland.

Why should you rewire your house?

You should rewire your house to drastically lower the chance of electrical fires, boost safety by replacing old, potentially hazardous wiring, raise your home’s resale value with a modern electrical setup, and maybe even cut down on your energy costs by enabling the use of more efficient appliances and lighting, particularly if your home has older wiring showing warning signs like flickering lights, burning odors, or discolored outlets.

Higher resale price:  Imagine two identical houses side-by-side, both valued at $300,000. One has original wiring from the 1960s, while the other has been completely rewired with modern copper wiring and a new electrical panel. The rewired house could realistically command a selling price of $306,000 – $315,000 (a 2-5% increase), simply because buyers are willing to pay a premium for the peace of mind and modern features. 

Improved appraisal value:  A buyer is looking to get a mortgage for a house with outdated aluminum wiring. The appraiser might lower the appraised value due to the potential fire hazard and the likelihood of future electrical issues. This could force the buyer to put down a larger down payment or even prevent them from securing financing altogether. Rewiring eliminates this issue, ensuring a smoother appraisal process and potentially better loan terms.

Lower Insurance cost: Your current homeowner’s insurance premium is $1,200 per year. After rewiring your house and providing proof of the upgrade to your insurance company, they might offer a 5-10% discount, reducing your annual premium by $60-$120. Over several years, these savings can add up significantly.

What are the Grants for Rewiring Houses in Ireland?

The grants for rewiring houses in Ireland are housing aid for older people and SEAI home energy grants. Here a detailed guide below.

Housing Aid for Older People Grant: This is the main grant specifically for rewiring. It’s available to homeowners aged 66 and over who are living in poor housing conditions. The grant can cover up to 95% of the cost of the rewiring work, up to a maximum of €8,000. To qualify, your household income needs to be below a certain threshold (currently €30,000). You’ll need to provide documentation about your income and a report from a registered electrician (with Safe Electric) outlining the necessary work. 

SEAI Home Energy Grants: While primarily focused on energy efficiency upgrades, these grants can sometimes cover elements of electrical work that are part of a larger energy upgrade project. For example, if you’re installing a heat pump, some rewiring might be necessary, and this could potentially be covered. However, it’s less likely to cover a full house rewire on its own.

Key things to remember about these grants:

Eligibility: There are specific criteria for each grant, so it’s important to check if you qualify.

Percentage of costs: The grants usually cover a percentage of the costs, not the full amount. 

Approved works: The work needs to be approved in advance and carried out by registered contractors. 

Application process: There’s an application process involved, and you’ll need to provide supporting documentation.
