Thinking about rewiring your home? It’s a big job — and one you don’t want to leave in the wrong hands. The right electrical contractor can make all the difference, not just in terms of the quality of the work, but also when it comes to safety, cost, and peace of mind. So, how do you separate the pros from the pretenders? 

Let’s walk through how to choose the right electrical contractor for house rewiring — and what could go wrong if you don’t.

How Can You Choose the Right Electrical Contractor for Your House Rewiring?

Let’s get into what you should look for when choosing the right person for the job.

1. Check Their Credentials

First things first — make sure they’re licensed and insured. This proves they’re qualified and gives you protection if anything goes wrong. Requirements can vary depending on where you live, so it’s worth checking with your local authority too.

2. Look at Reviews and Ask for References

A reputable contractor will be more than happy to share customer feedback or put you in touch with previous clients. Take a few minutes to read reviews — it can save you a lot of stress later.

3. Get a Few Quotes

Don’t settle on the first name you come across. Get at least three quotes so you can compare. And be cautious of any that seem suspiciously low — they could be cutting corners with materials or labour.

4. Pay Attention to Communication

Good communication goes a long way. Choose someone who listens, answers your questions clearly, and keeps you updated from start to finish.

5. Prioritise Experience

House rewiring, especially in older properties, comes with its own set of challenges. You want someone who’s done it before and knows what they’re doing.

6. Ask About Materials

Not all materials are created equal. Ask what kind of materials they’ll be using — high-quality components are essential for long-lasting and safe electrical systems.

7. Warranty Matters

Does the contractor back up their work with a warranty? They should. It shows confidence in the quality of their service and gives you added peace of mind.

8. Permits and Compliance

The right contractor will know what permits are needed and will make sure everything’s done by the book. Don’t assume — ask.

9. Talk Safety

Make sure they prioritise safety during the project. This applies not just to your home but also to the people working on-site.

10. Agree on a Timeline

Delays are frustrating. Have a clear discussion about how long the work will take and make sure you’re both on the same page.

Why is House Rewiring Necessary?

Before we dive into choosing the right electrical contractor, it’s worth understanding why you might need to rewire your home in the first place. It’s not always obvious, but there are a few key reasons it could be the right move.

1. Safety Concerns

Let’s start with the big one — safety. Old or damaged wiring can be a serious fire risk. If your system hasn’t been updated in years (or decades), there’s a good chance it’s not up to modern safety standards. Rewiring helps protect your home and your family.

2. Outdated Systems Can’t Keep Up

Most older homes weren’t built with today’s tech-heavy lifestyle in mind. Think smart TVs, laptops, chargers, appliances, even EV chargers. If your electrical system is constantly overloaded, it’s probably time for an upgrade.

3. You’re Renovating Anyway

Planning a major renovation? That’s the perfect time to tackle the wiring too. You’re already opening up walls or updating layouts, so it makes sense to future-proof your home while you’re at it.

4. Keeping Things Up to Code

Electrical codes don’t stay the same forever. If your home’s wiring is behind the times, you could run into problems when it comes to inspections, insurance, or selling down the line. Rewiring helps keep everything compliant and above board.

What are the Risks of Choosing the Wrong Electrical Contractor?

Before we dive into how to pick the right contractor, let’s talk about what can happen if you hire the wrong one. House rewiring isn’t something you want to gamble with.

1. Safety Hazards

Poor-quality rewiring can lead to serious dangers, including electrical fires or electric shocks. It’s not just about flickering lights — it’s about keeping your home and your family safe.

2. Wasted Time and Money

If the job isn’t done right the first time, you could end up paying for repairs or, worse, a full rewire all over again. Cheap work often leads to expensive problems.

3. Legal and Compliance Issues

Electrical work must meet local building codes. If your contractor skips this part or cuts corners, you could face fines or legal issues — not to mention the hassle of doing the job again properly.

4. Lower Property Value

When it comes time to sell or refinance, shoddy electrical work can bring down your home’s value. Surveyors and buyers will spot the signs, and it could cost you.

Frequently Asked Questions

How do I know if my house needs rewiring?

Some common signs include flickering lights, frequently tripping breakers, outdated fuse boxes, and discoloured outlets. If your home is over 30 years old and hasn't had a wiring upgrade, it’s a good idea to get it inspected by a qualified electrician.

How long does a full house rewire usually take?

It depends on the size of your home and the complexity of the job, but most full rewires take anywhere from 5 to 10 working days. Your contractor should give you a timeline upfront so you can plan accordingly.

Can I stay in my home during the rewiring process?

In some cases, yes — but be prepared for noise, dust, and disruption. Many people choose to stay elsewhere temporarily, especially if multiple rooms will be without power at the same time.

Do I need planning permission for house rewiring?

Not usually. However, the work must comply with local building regulations, and your contractor should handle the necessary permits and inspections. Always double-check that they’re taking care of this for you.

How much does house rewiring typically cost?

Prices vary based on the size and layout of your home, but in Ireland, you can expect a full rewire to cost anywhere from €4,000 to €10,000 or more. Always get a few detailed quotes to compare.

What should be included in a rewiring quote?

A good quote should include the cost of labour, materials, fixtures, removal of old wiring, and any required permits. Make sure it also outlines timelines and whether a warranty is included.
