A full house rewire is one of the biggest electrical jobs an Irish homeowner can undertake—but delaying unsafe or outdated wiring can create far bigger problems.
In 2026, the cost of rewiring a house in Ireland can range from roughly €5,000 for a smaller property to €14,000–€20,000+ for larger, occupied or more complex homes. There is no official national electrician price list, so every property needs to be assessed individually.

Average House Rewire Costs in Ireland 2026
| Property type | Indicative 2026 rewire cost |
|---|---|
| One-bedroom apartment | €5,000–€8,000 |
| Two-bedroom house | €8,000–€11,000 |
| Three-bedroom house | €9,000–€14,000 |
| Four-bedroom or larger home | From €14,000+ |
| Partial rewire | €1,200–€4,000+ |
These are general budgeting ranges. Current Irish 2026 guides vary significantly by county and specification; one nationwide guide lists a three-bedroom rewire at about €9,000–€14,000, while other published contractor guides show different regional and property-type ranges.
Prices depend on the size and age of the property, wall and floor construction, number of electrical points, consumer-unit requirements, access, location and whether the house is occupied during the work. Always confirm whether VAT, plaster repairs, decorating, alarms and certification are included.
What Is a Full House Rewire?
A full rewire generally involves replacing outdated fixed wiring throughout the property, installing new circuits, upgrading the consumer unit where required and fitting the agreed sockets, switches and lighting points. The installation is then inspected, tested and certified.
In Ireland, homeowners should use a Registered Electrical Contractor (REC). The Commission for Regulation of Utilities states that using a REC for electrical work in the home is required, and that a Completion Certificate should be provided for completed electrical work.
Electrical safety
Check Safe Electric registration before work begins
Safe Electric is the regulatory scheme for Registered Electrical Contractors in Ireland. Before appointing an electrician for a rewire, verify their current registration and confirm the certification arrangements in writing.
What Is a Live-In Rewire?
A “live rewire” usually means a live-in or occupied rewire—the homeowner remains in the property while the work is completed. It does not mean electricians carry out the work on energised conductors. Electrical work must be carried out using the appropriate safe-isolation procedures.
During an occupied rewire, the contractor may need to phase the work room by room so essential power can be safely restored at agreed stages. Homeowners should still expect periods without electricity, along with dust, wall chasing, lifted floors and restricted access.
Why Do Electricians Prefer an Empty House?
Vacant properties generally allow the team to work more efficiently and with fewer interruptions. In an empty property:
- Furniture and belongings are not blocking access.
- Floorboards and walls can be opened more efficiently.
- The work does not need to be phased around household use to the same extent.
- Tools and materials can be organised more easily.
- Testing and final changeover work is easier to schedule.
- There is less disruption for children, pets and household members.
An occupied rewire usually requires more planning, protection and daily management. Published 2026 Irish guides do not all use the same premium, but one current nationwide guide advises budgeting around 20%–30% extra for an occupied property because of the additional phasing and time involved.
Is a Live-In Rewire Still Possible?
Yes. Many electrical contractors can phase rewiring while a homeowner remains in the property, but whether that is practical depends on the house and household. It may be particularly disruptive for homes with young children, pets, mobility needs or people working from home.
Before deciding, discuss the programme, planned power outages, access, heating, hot water, daily clean-up and overnight safety arrangements with the electrical contractor.
What Should Be Included in Your Rewire Quote?
A detailed written quotation should make the full scope clear, including:
- The agreed number of sockets, switches and lighting points
- Consumer-unit and circuit upgrades
- Smoke and heat alarm requirements
- Testing and completion certification
- Whether plastering and decorating are included
- Waste removal and floor repairs
- VAT
- Optional wiring for EV chargers, heat pumps, solar PV, data or security systems
Comparing only the final price can be misleading. Compare the complete scope of work, products, certification, exclusions and making-good requirements.
