One of the most common questions we get is: how much will a full house rewire cost? The honest answer is that it depends on the property, but we can give you a clear picture of what drives the price and what a typical rewire looks like in terms of cost.
Typical Cost Ranges
For a standard three-bedroom semi-detached house in Ireland, a full rewire typically costs between €4,000 and €7,000 including materials. A two-bed terrace will usually come in at the lower end, while a four-bed detached property with multiple bathrooms and outbuildings can run to €8,000–€12,000. These figures include a new consumer unit, all new cabling, sockets, switches, and full RECI certification.
What Affects the Price
Several factors influence the final cost of a rewire:
- Property size — More rooms means more circuits, more cable runs, and more sockets and light points. A five-bed detached home simply has more work than a two-bed apartment
- Number of circuits — Modern installations use more circuits than older systems. Each room may have separate lighting and socket circuits, plus dedicated circuits for cookers, showers, and immersion heaters
- Access difficulty — Solid floors, concrete walls, and limited attic space all add time. A timber-framed house with good attic access is faster to rewire than a solid-wall cottage
- Specification level — The number of sockets per room, type of light fittings, smart home pre-wiring, and USB socket upgrades all affect the final price
- Consumer unit specification — A basic consumer unit with MCBs costs less than a fully loaded board with individual RCBOs on every circuit. We recommend RCBOs for the best protection
What's Included in Our Quotes
When we quote a rewire, the price covers everything:
- Removal of all existing wiring
- New consumer unit with RCBOs
- All new cable runs in modern twin-and-earth
- New sockets, switches, and back-boxes
- Smoke and heat detector system (hardwired)
- Full testing of every circuit
- RECI completion certificate
Light fittings and specialist items like EV charger pre-wiring are quoted separately so you can make choices based on your budget.
What's NOT Included
A few things sit outside the electrical quote that homeowners should budget for:
- Making good — Chasing walls and lifting floorboards leaves marks. Plastering and decoration are typically handled by your builder or plasterer, not the electrician
- Light fittings — We supply and fit them if you want, but many clients prefer to source their own
- External work — Garden lighting, outbuilding supplies, or gate automation are separate from the house rewire
How to Get an Accurate Quote
The best way to get a reliable quote is a site survey. We visit the property, walk through every room, discuss your requirements, and provide a fixed-price quote within 48 hours. The survey is free and there's no obligation. For a rough estimate before the survey, try our online estimate tool — it gives you a ballpark range based on the work you need.
Is It Worth the Investment?
A full rewire brings your property up to current safety standards, eliminates the risk of electrical faults in aging wiring, and adds genuine value to your home. If you're planning a sale, a recent RECI certificate gives buyers confidence. If you're staying put, you're investing in decades of safe, reliable electrical supply. Either way, it's one of the most worthwhile upgrades you can make to an older property.
