How much is it to rewire a house in Ireland in 2026? Most homeowners want a clear answer before booking an electrician, but the final price depends on the size and type of the property, access, the number of circuits, the chosen finish and the condition of the existing wiring.
As a general guide, a one-bedroom apartment may cost between €5,000 and €8,000, a two-bedroom house may cost between €8,000 and €11,000, a three-bedroom property may cost between €11,000 and €14,000, and a four-bedroom home may start from €14,000, excluding VAT.
These figures generally include labour and materials, but every contractor will price the work according to the survey and agreed scope.
A proper quotation should explain the electrical work, consumer unit upgrade, testing, certification and any additional costs. If one quotation is significantly cheaper than the others, ask exactly what it includes before accepting it.
how much is it to rewire a house 2026: A breakdown
| Property type | Typical cost range | 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-detached house | €8,000–€11,000 | 4–7 days | Access and the chosen finish can affect the price |
| 3-bed semi-detached house | €11,000–€14,000+ | 5–10 days | Common full-house rewire range |
| 4-bed detached house | Starting from €14,000+ | 7–14 days | Additional rooms, circuits and cable runs increase the cost |
Use these figures as a general guide only. The cost may change when the electrician opens floors, examines the consumer unit, tests the existing installation and confirms how much electrical work the house requires.
Why Does Rewiring Cost Vary So Much?
The size of the property usually has the greatest effect on the price. A larger home requires more cable, sockets, lighting points, protective devices and time on site. A compact apartment typically costs less than a detached house because there are 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 can slow down the job.
Location can influence the quotation. Labour costs may be higher in busy urban areas and commuter counties. Contractor availability, travel time and the supply of materials can also affect pricing.
The chosen specification matters too. Standard white sockets and switches cost less than decorative finishes. Additional sockets, outdoor lighting, garden power, EV charger cabling, smart controls, CCTV, data points and electric shower circuits all increase 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 that the property can safely support modern appliances, lighting, heating controls and everyday power use.
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 use a Registered Electrical Contractor for domestic electrical work. Safe Electric registered contractors are required to provide the appropriate completion certification for completed electrical work.
What Does a Quote Usually Exclude?
Many homeowners focus on the headline price and overlook the exclusions. A rewiring quotation may not include plastering, painting, flooring repairs, kitchen refitting, alarm systems, broadband cabling, smart-home equipment, EV chargers or solar PV wiring unless these are clearly listed.
You should also allow for additional costs if the electrician discovers unsafe previous work, damaged cables, poor earthing, asbestos risks, hidden junction boxes or water damage.
A clear quotation should state what is included, what is excluded and how any variations will be priced.
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 renovating a kitchen, upgrading a bathroom, replacing an old lighting circuit or installing a new appliance circuit.
A partial rewire usually costs less initially. However, it may not solve the underlying problem when old wiring runs throughout the house. If the property still contains rubber, fabric, lead or deteriorating PVC wiring, a partial rewire may only delay the full upgrade.
A full house rewire generally provides better long-term value when the wiring has reached the end of its useful life. It can also make sense during a renovation because electricians can install cables before plasterers, decorators and flooring contractors complete the rooms.
Signs Your House May Need Rewiring
Arrange an electrical inspection if you notice any of the following warning signs:
- Breakers trip frequently
- Fuses blow regularly
- Sockets or switches feel warm
- You notice a burning smell near an outlet
- Lights flicker
- Switches buzz or crackle
- The fuse board appears old or damaged
- You rely on extension leads every day
- The house has too few sockets
- The wiring uses old rubber or fabric insulation
- The electrical installation has not been checked for many years
These signs do not always mean that you need a complete rewire, but they do indicate that the installation should be inspected. An electrician can determine whether you require a full rewire, partial rewire, 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 project usually progresses faster when the property is empty. Electricians may need to lift floorboards, chase walls, turn off the power, move furniture and work through each room in sequence.
If you stay in the property, the electrician must make the work area safe at the end of each day. This additional work can increase labour time and cost. Where possible, arrange temporary accommodation during the most disruptive stages.
Are There Grants for Rewiring in Ireland in 2026?
Some homeowners may qualify for support, but you must generally apply and receive approval before the work begins.
The Housing Aid for Older People Grant may help older people living in poor housing conditions carry out necessary repairs or improvements. The amount available depends on income, eligibility and the approved cost of the work.
The Vacant Property Refurbishment Grant may also help when bringing a vacant or derelict property back into use. Rewiring may be included as part of a wider approved renovation.
Check the latest grant rules before booking any work because local authorities manage applications and may request quotations, proof of ownership, proof of vacancy and other supporting documents.
How to Keep Rewiring Costs Under Control
Plan the electrical layout before work begins. Decide where you want sockets, switches, lighting, outdoor power, internet points and future upgrades. Changes made after work has started usually increase the price.
Choose practical fittings where premium finishes are unnecessary. Decorative switches can be used in visible rooms, while standard fittings can be installed 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 quotations carefully. Do not automatically choose the cheapest option unless it includes testing, certification, the consumer unit, accessories and all essential safety work.
