House rewiring cost in Ireland
Legacy guide: external source review is pending. How we review guides
A full house rewire is one of the bigger electrical jobs a homeowner can face, but it is often essential in older Irish homes with outdated wiring, too few sockets, old fuse boards or unsafe alterations. It is also the type of job where choosing the cheapest quote without checking certification can become very expensive later.
In 2026, many Irish rewiring quotes range from about €4,000 for a small one-bed property to €22,000 or more for large homes with complex layouts. For a typical three-bed house, homeowners often see quotes around €8,000 to €12,000 depending on access, finish level and electrical specification.

What changes the rewire price
- The number of sockets, switches, lights and circuits you want.
- Whether the house is occupied, furnished or empty during the work.
- Wall construction, attic access, floors, extensions and old alterations.
- Smart controls, EV charger preparation, data cabling, alarms or outdoor power.
- Plastering, painting and making good after cables are chased into walls.
Use a registered electrician
Electrical work in an Irish home should be carried out by a Registered Electrical Contractor. For a rewire, ask before booking whether the quote includes testing, certification and a clear schedule of circuits. HomePros.ie can help you compare local electricians, but you should still check registration and insurance before work starts.
How to compare quotes
Ask every electrician to price the same socket count, lighting plan, consumer unit, smoke alarms, extractor fans and external power. A low quote may not include enough outlets, making good, certification, access work or extra circuits you will want once walls are open.
