How Much Does It Cost to Rewire a House in 2026?
How much is it to rewire a house in Ireland in 2026? Most homeowners want a clear answer before they book an electrician, but the final price depends on the size of the property, the property type, access, the number of circuits, the finish you choose and the condition of the existing wiring.
As a guide, recent Irish pricing data places a 2-bed full house rewire around €4,500–€7,000, a 3-bed semi around €6,500–€9,500, and a 4-bed detached home around €9,000–€14,000, excluding VAT. These figures usually include labour and materials, but every contractor will price the job based on the survey and the scope.
A proper quote should explain the electrical work, the consumer unit upgrade, testing, certification, and any additional costs. If a quote looks much cheaper than the rest, ask exactly what it includes before you accept it.
House Rewiring Cost Guide for 2026
| Property type | Typical cost range (Starts From) | Typical timeline | Notes |
|---|---|---|---|
| 1-bed apartment or small flat | €5,000–€8,000 | 3–5 days | Simple layouts usually reduce labour time |
| 2-bed terraced or small semi | €8,000–€11,000 | 4–7 days | Access and finish can move the price |
| 3-bed semi-detached house | €1,100–€1,400+ | 5–10 days | Common full house rewire range |
| 4-bed detached house | €14,000+ | 7–14 days | More rooms, circuits and cable runs add cost |
| Large, period or occupied home | €14,000–€25,000+ | 10–15+ days | Complex access and premium finishes increase cost |
Use these figures as a guide only. The cost of rewiring changes when the electrician opens floors, checks the consumer unit, tests the existing installation and confirms how much electrical work the house needs.
Why Does Rewiring Cost Vary So Much?
The size of the property usually has the biggest impact on price. A larger home needs more cable, more sockets, more lighting points, more protective devices and more time on site. A compact apartment typically costs less than a detached house because the electrician has fewer cable routes and circuits to install.
Access also affects labour costs. Timber floors, clear attic space and empty rooms help electricians work faster. Solid walls, concrete floors, fitted wardrobes, tiles, old plaster and poor attic access all slow the job down.
Location can also influence the quote. Labour costs often rise in busy urban areas and commuter counties. In the south east and other high-demand regions, contractor availability, travel time and material supply can also affect pricing.
Your chosen specification matters too. Standard white sockets and switches cost less than decorative finishes. Extra sockets, outdoor lighting, garden power, EV charger cabling, smart controls, CCTV, data points and electric shower circuits all add to the scope.
What Does a Full House Rewire Include?
A full house rewire does more than replace old cables. It upgrades the electrical installation so the home can handle modern appliances, lighting, heating controls and day-to-day power use safely.
A typical full house rewire may include:
- Removing or isolating old wiring
- Installing new socket circuits
- Installing new lighting circuits
- Adding kitchen appliance circuits
- Wiring bathrooms and showers where required
- Replacing switches and sockets
- Upgrading the consumer unit
- Improving earthing and bonding
- Installing smoke and heat alarm wiring where included
- Testing, inspecting and certifying the installation
In Ireland, you should always use a Registered Electrical Contractor for domestic electrical work. The Commission for Regulation of Utilities says homeowners should use a Registered Electrical Contractor, and Safe Electric-registered contractors must give homeowners a Completion Certificate for completed work.
What Does a Quote Usually Exclude?
Many homeowners focus on the headline price and miss the exclusions. A rewiring quote may not include plastering, painting, flooring repairs, kitchen refitting, alarm systems, broadband cabling, smart home equipment, EV chargers or solar PV wiring unless the contractor lists them clearly.
You should also allow for additional costs if the electrician finds unsafe previous work, damaged cables, poor earthing, asbestos risk, hidden junction boxes or water damage. A clear quote should state what it includes, what it excludes and how the contractor prices variations.
Full House Rewire vs Partial Rewire
A partial rewire updates one area or a small group of circuits. You might choose a partial rewire when you renovate a kitchen, upgrade a bathroom, replace an old lighting circuit or add a new appliance circuit.
A partial rewire typically costs less upfront. However, it may not solve the deeper problem if old wiring runs throughout the house. If the home still has rubber, fabric, lead or deteriorating PVC wiring, a partial rewire may only delay the full upgrade.
A full house rewire usually gives better long-term value when the wiring has reached the end of its life. It also makes sense during a renovation because electricians can run cables before plasterers, decorators and flooring contractors finish the rooms.
Signs Your House May Need Rewiring
Book an inspection if you notice any of these warning signs:
- Breakers trip often
- Fuses blow regularly
- Sockets or switches feel warm
- You smell burning near an outlet
- Lights flicker
- Switches buzz or crackle
- The fuse board looks old or damaged
- You rely on extension leads every day
- The house has too few sockets
- The wiring uses old rubber or fabric insulation
- No electrician has checked the wiring in many years
These signs do not always mean you need a full rewire, but they do mean you should get the installation checked. An inspection can show whether you need a full house rewire, a partial rewire, a consumer unit upgrade or smaller remedial work.
Can You Live in the House During a Rewire?
You can sometimes stay in the house during a rewire, but the job usually runs faster when the property is empty. Electricians may need to lift floorboards, chase walls, turn off power, move furniture and work through each room in sequence.
If you stay in the property, the electrician must make the area safe at the end of each day. That extra work can increase labour time and cost. When possible, arrange temporary accommodation during the most disruptive stage.
Are There Grants for Rewiring in Ireland in 2026?
Some homeowners may qualify for support, but you must usually apply and receive approval before the work starts.
The Housing Aid for Older People Grant helps older people living in poor housing conditions carry out necessary repairs or improvements. Gov.ie states that the effective maximum grant is €10,700, and the grant may cover up to 100% of approved costs depending on income and eligibility.
The Vacant Property Refurbishment Grant may also help if you bring a vacant or derelict property back into use. Gov.ie states that the grant offers up to €50,000 for a vacant property, with a derelict property top-up of up to €20,000, bringing the total to €70,000 where the property qualifies.
Check the latest grant rules before you book work, because local authorities manage applications and may ask for quotes, proof of ownership, proof of vacancy and other documents.
How to Keep Rewiring Costs Under Control
Plan the layout before work starts. Decide where you want sockets, switches, lights, outdoor power, internet points and future upgrades. Mid-job changes usually increase the price.
Choose practical fittings where premium finishes do not matter. You can use decorative switches in visible rooms and standard fittings in utility rooms, storage areas and behind appliances.
Schedule the rewire before plastering, painting, flooring or kitchen installation. Electricians can work faster when walls, floors and ceilings remain accessible.
Compare quotes carefully. Do not choose the cheapest option unless it includes testing, certification, the consumer unit, accessories and all essential safety work.
