If you’ve been searching for a full house rewire cost in Ireland in 2026, you’re looking at around €7,500 to €15,000 in total. Now, this cost does fluctuate quite a bit, and the real answer is that it depends on factors like your property size, the age of your current wiring, and its condition.
In Cork City and County, the cost of a full house rewire will usually fall within this range, but it’s important that a qualified electrician inspect your home and get some more specific information before giving you an accurate quote.
This article will cover the cost to rewire an entire house in Cork and give some more detailed cost breakdowns based on various factors.
What Does the Average Full House Rewire Cost in Ireland?
A full house rewire in Ireland may be simple or complex, depending on how big the house is and its layout. Generally, the number of bedrooms is a good gauge for how much a given project will cost, so we’ve provided some guide prices below for reference:
- 2-bedroom home: €7,500-€9,000
- 3-bedroom semi-detached home: €9,000-€13,000
- 4-bedroom detached home: €13,000-€15,000
Given the popularity of 3-bedroom homes in Cork, the electrician rewiring cost for such a home is reflective of what you’ll be quoted.
Keep in mind that, in addition to the number of bedrooms, a quoted price will vary depending on the property’s condition, the number of electrical sockets, if consumer unit upgrades are necessary, and if the home will be occupied during works.
What Affects the Cost of a House Rewire?
How much does a whole house rewire cost, and what affects the quoted price? Here’s what we typically factor in when estimating a full house rewire cost:
- Size of the property: small homes tend to cost less than larger homes.
- The house’s age: as older homes are common in Cork City, often with outdated wiring, this will drive up costs.
- Access to wiring: if wiring is easily accessible, costs tend to be lower. If wiring is located behind plaster walls or under rigid flooring, this can increase complexity and costs.
- If the house is occupied during works: while electricians endeavour to minimise disruption, they do need to access rooms throughout the house. If the home is vacant, they can complete works much faster than if the home remains occupied.
- Desired upgrades: if homeowners want additional sockets or upgrades to lighting or other modern features, these come at an additional cost.
Cost Differences by Property Type in Cork
The layout of your home will also play an important role in determining the cost of a full house rewire. In Cork County, there are several types of homes which we work on which often have similar characteristics. Here’s a brief breakdown:
- Old terraced homes (Cork City centre & suburbs): these homes almost always have solid masonry construction, which makes the removal of existing wiring and routing of new wiring complex. Moreover, these homes usually have very outdated wiring, so costs skew higher.
- Semi-detached homes (suburban Cork): perhaps the most common home layout dating back to around the 60s to 90s, we often find that these homes have timber flooring and cavity walls that make it fairly easy to rewire them. Costs often fall on the lower to mid end of the range.
- Detached rural homes (Cork countryside & commuter routes): naturally common in towns like Fermoy and Midleton, these homes tend to be a little more spacious, which in turn means more wiring needed to run throughout the home. Wiring may be outdated as well, but costs generally fall within the mid to upper range.
Additional Costs to Keep in Mind
Rewiring a home isn’t always just about removing old wiring and replacing it with new electrical wiring. There are several desirable or necessary modifications that may be made during a project, which will increase costs. Some examples include:
- New fuse board or consumer unit: strongly recommended as part of full house rewiring services. May cost €500 or more depending on the unit model and specification needed.
- Extra sockets or lighting upgrades: a full house rewire is an excellent opportunity to add more electrical sockets, USB wall ports, or lighting fixtures throughout the home. Adding new sockets/fixtures or upgrading existing ones might cost an additional €1,000 or more, depending on how many are desired.
- Smart home integrations: modern homes are increasingly adopting smart home technologies, which add all sorts of useful and practical features. Depending on the type of wiring and installation desired, a smart home system could cost €2,000 or more.
- Replastering & repainting: rewiring usually requires chasing cables that run behind plaster walls which will need to be replastered and repainted afterwards. Plasterwork and painting could cost around €2,000 depending on how much needs to be done.
- Energy-efficient upgrades: along with smart home features, rewiring also presents a great opportunity to upgrade to energy-efficient features such as LED light circuits, EV charging ports, or solar PV infrastructure. These can cost around €1,000-€4,000, depending on what is installed.
Is It Cheaper to Rewire During Renovations?
It may be much cheaper to have your house rewired during renovation projects. Firstly, it makes the task much easier and faster for electricians, as there are no disruptions to their work. Your electrician can provide you with an estimated timeline to completion so that you can make arrangements to sleep elsewhere.
If you must remain at home during rewiring, you might want to consider partial rewiring for one or more rooms so that you have minimal disturbance and disruption to your daily activities.
What Do Safe Electric Regulations Say?
Safe Electric is the statutory regulatory body for electrical contractors in Ireland, so their standards and regulations are the authority by which all contractors must comply with. It’s important to always ensure that you are hiring a Safe Electric Registered Electrical Contractor (REC) to ensure full compliance and peace of mind. All electrical contractors must also adhere to ET101, the National Rules for Electrical Installations, for all works carried out.
When an REC-registered electrician completes a rewiring job, they must perform electrical inspections and testing to ensure it’s safe and functional, as well as provide you with a Completion Certificate. This document confirms that the work was carried out in compliance with ET101 and that your new home wiring has been inspected and tested professionally.
See our homepage and verify our registered status at Safe Electric, and rest assured that you’re dealing with dedicated REC-registered electricians when you choose Cork Electrical.
