How much does it cost to rewire a house Ireland-wide in 2026? For most homes, the answer falls between €6,000 and just over €20,000. The final figure depends on the size of the property, the condition of your existing home wiring and the complexity of the job.
This guide breaks down current prices, explains the factors that affect the cost and shows you practical ways to keep the overall price down.
How Much to Rewire a House Ireland: 2026 Price Guide
Every home is different, so no two rewires cost exactly the same. Still, the ranges below reflect what registered contractors across Ireland typically quote for a full house rewire.
| House type | Typical cost (2026) | Typical duration |
|---|---|---|
| 1-bed apartment | €5,000–€8,000 | 3–4 days |
| 2-bed terrace or apartment | €8,000–€11,000 | 4–6 days |
| 3-bed semi-detached | €11,000–€14,000 | 5–8 days |
| 4-bed detached | Starting from €14,000+ | 7–10 days |
Dublin prices generally sit at the top of these ranges, while Cork and other regional areas may come in slightly lower. The cost of rewiring has climbed since 2022 because of increases in material prices, labour costs and the number of protective devices required in a modern installation.
Before comparing quotes, confirm whether each price includes VAT and the completion certificate. Some contractors list these separately, which can change the final amount you pay.
What Affects the Cost of Rewiring a House?
You might ask yourself how much to rewire a house Ireland, but then also think about the several factors that can push the price of a rewire up or down:
- House size and layout. More rooms mean more circuits, more cable and more sockets, increasing both materials and labour.
- Outdated wiring. Rubber-insulated or aluminium wiring, which may be found in older properties, takes longer to remove safely.
- Floor construction. Cables can usually be routed easily under timber floors. Solid concrete floors may require wall chasing or surface trunking, which takes additional time.
- Living in the house. If you remain in the property, electricians usually have to work room by room and restore power at the end of each day. This can add 15% to 20% to the bill.
- Smart-home upgrades. A rewire is a suitable time to add smart switches, USB-C sockets or multi-room wiring, but each extra feature increases the cost.
- Period features. Listed buildings and properties with original plasterwork need more careful cable routing, adding to the complexity of the job.
What Does a Full House Rewire Include?
When you rewire your home properly, the electrician replaces and upgrades the electrical installation throughout the property.
A full rewire will commonly include:
- A new consumer unit to replace an old fuse board, with appropriate circuit protection
- Complete cable replacement throughout the house
- New sockets, switches and light fittings
- Hard-wired, interconnected smoke and heat alarms
- Full testing and inspection to the applicable Irish standards
- A Safe Electric completion certificate
Plastering repairs and repainting usually sit outside the electrical quote, so you should budget for those separately.
How to Keep the Overall Price Down
- Check your grant eligibility. The Housing Aid for Older People scheme may support essential rewiring for eligible older homeowners, while the Vacant Property Refurbishment Grant may fund electrical work as part of a wider refurbishment.
- Rewire while the house is empty. A vacant property is usually faster and cheaper to rewire than an occupied one.
- Bundle the work. If you are planning an attic conversion, extension or full renovation, schedule the rewire at the same time to reduce repeated opening and repair work.
- Act before it becomes urgent. An emergency rewire will usually cost more than a planned one. If your wiring is 25 years old or more, arrange an inspection rather than waiting for a fault.
Why Choose a Registered Electrician?
In Ireland, only a registered electrician can legally certify a house rewire. Safe Electric manages the register, audits registered contractors and provides the certification process required for completed electrical work.
The completion certificate protects you over the long term. Insurers may ask about the age and condition of the wiring in older homes, and uncertified electrical work could create difficulties if you need to make an insurance claim.
Frequently Asked Questions
How Often Should a House Be Rewired in Ireland?
There is no fixed replacement date for every electrical installation. However, homeowners should arrange periodic inspections, particularly when the wiring is older, the fuse board is outdated or the property has not been inspected for many years.
Can You Rewire a House in Stages?
You can rewire a house in stages, but one planned project often works out cheaper than several smaller jobs. A staged rewire can repeat setup, testing and certification costs during each phase.
Does Rewiring Add Value to a Home?
Rewiring can improve the appeal and value of an older property. Buyers and surveyors often identify outdated wiring quickly, while a modern installation supported by a Safe Electric completion certificate removes a major concern.
