Are you worried about the rewiring cost in Ireland? Rewiring your home is not just a maintenance task; it's an investment in your safety and your property’s future. Old and outdated wiring isn't only inefficient—it can be dangerous, creating risks of electrical fires and other hazards.

‍By updating the wiring in your home, you not only increase safety but also improve the functionality of your electrical system, allowing it to handle modern appliances and technology. Additionally, a well-executed rewiring job can increase the value of your home by ensuring that it meets current electrical standards. 

‍This blog will help you to understand and find out the average cost to rewire a house in Ireland and learn the factors that can impact the total priceadditional expenses and budgeting tips.

‍So, if you're considering the benefits of rewiring, let's start exploring what it involves and how much it might cost you in Ireland.

What is The Average Cost of Rewiring a House in Ireland?

When considering rewiring your house in Ireland, the cost can vary widely depending on several factors such as the size of your house, the age of your existing electrical system, and the complexity of the job required. On average, you can expect to pay between €4,500 and €6,500 for a standard three-bedroom house.

 This estimate typically covers the cost of materials and labour, including the replacement of old wires, installation of new sockets, and updating of the fuse board to meet current safety standards.

For smaller homes or less detailed rewiring jobs, costs might be lower, while larger properties or those requiring more extensive upgrades could see costs rising significantly. It's also important to consider additional costs that may arise, such as repairing walls after wiring or upgrading other electrical fixtures in the home.

What Are the Factors That Affect The Cost of Rewiring in Ireland?

When planning to rewire your house, several key factors can significantly influence the overall cost of the project. Being aware of these can help you budget more accurately and make informed decisions during the planning stage.

Size of the home

Larger homes naturally require more materials and labour, which can increase the cost of rewiring. More wiring, sockets, and switches are needed to hold the increased space, and the labour to install these will also be greater. This means that a larger property could significantly increase the overall price compared to a smaller home.

Age of the home

Older homes often pose more challenges due to their outdated and potentially destroyed wiring systems. These properties may need more detailed updates to bring them up to current electrical standards, which can include replacing old wiring that is no longer safe or efficient. The more defined the updates, the higher the costs involved.

Complexity of the project

The complexity of the rewiring project also affects the price. If you need additional circuits for new appliances or specialised areas like home offices or workshops, this will increase the work and materials needed. Custom requirements like smart home technology or specialised lighting also add to the complexity and cost.

Quality of materials

Choosing higher-quality materials can increase the upfront costs of rewiring but can provide better durability and safety. While it might be appealing to go for cheaper options, investing in quality can reduce the need for repairs and replacements in the future, ultimately saving money in the long run.

Labour costs

The cost of labour can vary widely depending on where you live in Ireland. Urban areas, particularly cities like Dublin, may have higher labour rates compared to rural areas. Additionally, the scope of work—how much needs to be done and how complex the tasks are—will also impact the total labour costs.

What Are The Additional Expenses to Consider for Rewiring Your Home?

When budgeting for a house rewiring project in Ireland, it’s crucial to account for more than just the basic costs of materials and labour. Several additional expenses can impact the total cost and should be considered to ensure you have an accurate financial plan.

Wall repairs: 

After rewiring, the walls where wires have been replaced or new ones installed may need repairs. This includes plastering over chases and repainting or redecorating to bring the walls back to their original condition. These costs can add up, especially if you have extensive rewiring or if the aesthetic finish is important.

Upgrading electrical fixtures: 

While rewiring your home, it might be practical to upgrade switches at the same time, sockets, and other fixtures to newer, safer models. This is the best time to make these improvements, but it will increase the project cost.

Uncertain fund:

 It's wise to set aside an emergency  fund of about 10-20% of the total project cost. This fund covers unexpected issues or expenses that arise during the project, such as discovering outdated components that also need replacement.

Permit and inspection fees: 

Depending on your location, you may need to pay for permits and post-project inspections to ensure the rewiring complies with local regulations and safety standards. These costs vary by area but are necessary for the legality and safety of the work performed.


In a nut-shell, the cost of rewiring a house in Ireland can vary significantly based on factors like the size and age of the home, the complexity of the project, the quality of materials used, and regional labour rates. 

‍While initial costs may seem high, the safety, functionality, and potential increase in property value make it a worthwhile investment. Remember to budget for additional expenses and look for ways to save where possible.
