How Much to Rewire a House in 2024? (Costs & Factors)

Rewiring a house is no small feat, and it’s definitely not something you want to skimp on. I mean, we’re talking about the electrical lifeblood of your home here! But let’s be real, you’re probably wondering just how much this whole rewiring business is going to set you back. No nonsense, no complicated terminology – just the information you need to know. So, let’s dive in and get to the bottom of this!

How Much Does It Cost to Rewire a House in the UK?

If you’re living in an older home, chances are the wiring is outdated. Faulty or old wiring isn’t just an inconvenience – it’s a serious safety hazard. Over 50% of accidental house fires are caused by electrical malfunctions. So if you’re wondering, “how much does it cost to rewire a house in the UK?”, I’ve got you covered. As an electrician with over 20 years of experience, I’ve rewired countless homes. And let me tell you, the cost to rewire a house can vary quite a bit.

Factors That Affect the Cost of Rewiring

The average cost of rewiring a house in the UK ranges from £2,500 to £6,000. But several key factors can make that price tag fluctuate:

  • Size of your property
  • Age and condition of the existing wiring
  • Accessibility of the wiring
  • Extent of rewiring needed
  • Location (prices tend to be higher in London)

Average Costs for Different House Sizes

To give you a ballpark idea, here are the typical house rewiring costs based on property size:

  • 1-bedroom flat: £2,000 – £3,000
  • 2-bedroom house: £3,000 – £4,000
  • 3-bedroom house: £4,000 – £5,500
  • 4-bedroom house: £5,500 – £7,000

Keep in mind, these are averages. I’ve seen rewiring jobs cost as little as £1,500 for a small flat, and upwards of £10,000 for a large, complex rewire of a period property.

Additional Costs to Consider

On top of the base rewiring cost, there are some extra expenses to factor in:

  • Electrical inspection: £100 – £300
  • New consumer unit: £400 – £800
  • Plastering and decorating: £500 – £2,000
  • Temporary accommodation during rewire: £500+

It’s easy for these additional costs to sneak up on you. That’s why I always advise my clients to budget an extra 10-20% on top of the quoted rewiring price, just to be safe.

Factors That Affect the Cost of Rewiring a House

I’ve already touched on some of the main factors that influence house rewiring costs. But let’s dive a bit deeper into each one.

Age and Condition of Existing Wiring

The older and more deteriorated the existing wiring is, the more work it will take to replace it. If your home was built before the 1960s and still has the original wiring, a full rewire is likely necessary. Some telltale signs of outdated wiring are:

  • Fabric or rubber coated wires
  • Old-fashioned fuse boxes with ceramic fuses
  • Sockets mounted on skirting boards
  • Frequent blown fuses or tripped circuits

Size and Type of Property

It’s simple math – larger homes with more rooms will cost more to rewire than smaller ones. The type of property matters too. A 4-bedroom detached house will be pricier to rewire than a 2-bed flat, even if they have a similar square footage. Period properties and listed buildings often have more complex wiring requirements, which can bump up the cost. I once rewired a beautiful Victorian terrace that had unique challenges like lath and plaster walls. It required a lot of extra time and care.

Location and Accessibility

Rewiring costs tend to be higher in London and the South East compared to other parts of the UK. But even within a city, prices can vary depending on the specific location and accessibility of the property. If the wiring is difficult to access due to the building’s construction or layout, the job will take longer and cost more. High ceilings, concrete walls, and cramped crawl spaces can all add to the complexity (and the price).

Extent of Rewiring Required

The scope of the rewiring project is a big factor in the final cost. If your home only needs a partial rewire of a few circuits, it will be much cheaper than a full rewire of the entire property. However, it’s important not to cut corners. If your electrician recommends a full rewire for safety reasons, it’s best to bite the bullet and do it right. Skimping on essential electrical work is just not worth the risk.

Choice of Materials and Fittings

Finally, the materials and fittings you choose will impact the overall cost of your rewire. Basic white plastic sockets and switches are the most budget-friendly option. But if you want premium finishes like brushed brass or designer lighting, be prepared to pay more. I always encourage my clients to invest in good quality wiring and components. Skimping on materials might save a few quid upfront, but it can lead to reliability issues and even safety hazards down the road.

The Rewiring Process: What’s Involved?

Now that you have a better idea of the costs, let’s talk about what actually happens during a house rewire. As a qualified electrician, I’ve fine-tuned my rewiring process over the years to be as efficient and non-disruptive as possible.

Initial Electrical Inspection

The first step is an in-depth electrical inspection of your property. This is when I assess the condition of the existing wiring, identify any safety issues, and determine the scope of work required. I provide a detailed report of my findings and recommendations, along with a quote for the rewiring work. This inspection typically costs between £100 and £300, depending on the size of the property.

Upgrading the Consumer Unit

One of the first jobs in the actual rewiring process is upgrading the consumer unit (or fuse box) to meet current regulations. The old fuse box is replaced with a modern one that includes RCD protection for added safety. This is a crucial step that shouldn’t be skipped, even if you’re only doing a partial rewire. A new consumer unit will cost anywhere from £400 to £800, including installation.

Installing New Wiring and Sockets

Next comes the bulk of the rewiring work – running new cables throughout the property and fitting new plug sockets. This is where the real disruption happens, as floorboards are lifted and holes are drilled to accommodate the new wiring. I always try to run cables in the least invasive way possible, but some upheaval is unavoidable. Furniture will need to be moved and carpets or flooring may need to be temporarily removed.

Fitting New Lights and Switches

Once the new wiring is in place, it’s time to install new light fittings and switches. This is a good opportunity to upgrade to more energy-efficient LED lighting or to change the style of your fittings. I work with my clients to design a lighting scheme that meets their practical needs and aesthetic preferences. Whether you want smart home automation or vintage-style switches, there are endless options to choose from.

Plastering and Decorating

The final stage of the rewiring process is making good any damage to walls and ceilings. Chasing cables into walls and lifting floorboards inevitably leads to some cracking and holes that need to be repaired. I always aim to minimize the amount of plastering and decorating required, but it’s still a significant part of the job. Depending on the extent of the damage, this can add anywhere from £500 to £2,000 to the total rewiring cost. Some of my clients choose to do the decorating themselves to save money. But if you’re not confident in your DIY skills, it’s best to leave it to a professional plasterer and decorator.

Choosing a Qualified Electrician for Your House Rewire

Rewiring your home is a big job that requires a high level of skill and expertise. It’s not something you want to entrust to just anyone. Choosing a qualified, experienced electrician is crucial for the safety and quality of the work.

Checking Qualifications and Accreditations

When vetting potential electricians, always ask about their qualifications and accreditations. At a minimum, they should have a Level 3 NVQ diploma in electrical installations or equivalent. Look for electricians who are registered with a recognized trade body like NICEIC or ELECSA. These organizations vet their members to ensure they meet strict technical and safety standards.

Getting Multiple Quotes

I always recommend getting at least three quotes from different electricians before making a decision. But don’t just go for the cheapest option – make sure you’re comparing like for like in terms of the scope of work and quality of materials. A good electrician will provide a detailed quote that breaks down all the costs involved. Be wary of quotes that seem too good to be true – they probably are.

Ensuring Compliance with Building Regulations

All electrical work in the UK must comply with Part P of the Building Regulations. This is a legal requirement that ensures the safety and quality of electrical installations. Make sure your chosen electrician is up to date with the latest regulations and will carry out the work in compliance with these standards. If they can’t provide evidence of this, look elsewhere.

Obtaining an Electrical Installation Certificate

Once the rewiring work is complete, your electrician should provide an Electrical Installation Certificate (EIC). This is a legal document that confirms the installation has been designed, constructed, inspected and tested in accordance with BS 7671 (the UK standard for electrical installations). The EIC is your proof that the work has been carried out safely and to the required standard. Keep it in a safe place, as you may need to present it to your local building control or insurance company.

Signs That Your House Needs Rewiring

Is your home’s electrical system showing its age? Outdated or faulty wiring isn’t just a nuisance; it can be downright dangerous. Here are some telltale signs that your house may need rewiring:

Frequent Electrical Issues

If you’re constantly dealing with flickering lights, tripping circuit breakers, or blown fuses, it’s a red flag that your wiring is on its last legs. These frequent electrical issues are more than just annoying; they’re a sign of a bigger problem lurking behind your walls.

Outdated Fuse Box

Does your home still have an old-fashioned fuse box with ceramic fuses? If so, it’s a clear indication that your electrical system is outdated and due for an upgrade. Modern homes require a more robust and safer setup, like a circuit breaker box.

Old and Deteriorating Wiring

If your home has old, fabric-covered wiring or cables with crumbling insulation, it’s time to call in the professionals. This type of poor wiring is a fire hazard waiting to happen. Don’t wait until it’s too late to address this serious safety issue.

Lack of Sufficient Sockets

Are you constantly relying on extension cords and power strips to plug in all your devices? A lack of sufficient electrical sockets is a common problem in older properties that weren’t built to handle the electrical demands of modern life. Rewiring can add more outlets and bring your home up to speed.

Recent Electrical Inspection Recommendations

If a recent electrical inspection has uncovered issues with your wiring or recommended a rewire, don’t ignore that advice. These professionals know what they’re talking about, and their recommendations are based on keeping you and your family safe.

The Importance of Rewiring Your House

Rewiring your home might seem like a daunting and expensive task, but trust me, it’s an investment in your safety and peace of mind. Here’s why it’s so crucial:

Ensuring Electrical Safety

The number one reason to rewire your house is to ensure safety. Outdated or faulty wiring is a leading cause of electrical fires, which can be devastating. By upgrading your wiring, you can rest easy knowing that your home and loved ones are protected.

Meeting Current Building Regulations

Building codes and regulations are constantly evolving to improve safety standards. If your home’s wiring is old, it likely doesn’t meet current requirements. Rewiring brings your electrical system up to code and ensures that it’s legal and compliant.

Preventing Electrical Fires

Electrical fires are no joke. They can start suddenly and spread quickly, causing massive damage and putting lives at risk. Rewiring your home is one of the best ways to prevent electrical fires and keep your property and family safe.

Improving Energy Efficiency

Did you know that old, inefficient wiring can actually waste electricity and drive up your energy bills? By upgrading to modern wiring and components, you can improve your home’s energy efficiency and save money in the long run.

Enhancing Property Value

A fully rewired house with a safe, up-to-date electrical system is a major selling point for potential buyers. If you’re thinking of putting your home on the market, investing in a rewire can boost its value and make it more attractive to buyers.

How to Save Money on Your House Rewire

I get it; rewiring your home is a significant expense. But there are ways to save money without cutting corners on safety. Here are some tips:

Comparing Quotes from Multiple Electricians

Don’t just go with the first electrician you find. Get quotes from several professionals and compare their prices and services. This will help you find the best deal and ensure you’re getting a fair price.

Opting for Standard Fittings

It’s tempting to splurge on fancy, designer light fixtures and switches, but opting for standard, good-quality fittings can save you a bundle. Remember, it’s what’s behind the walls that really counts when it comes to safety.

Doing Preparatory Work Yourself

If you’re handy, you might be able to tackle some of the prep work yourself, like lifting floorboards or removing old fixtures. Just be sure to leave the actual electrical work to the licensed pros.

Rewiring in Stages

If your budget is tight, consider rewiring your home in stages, focusing on the most critical areas first. This can spread out the cost over time and make the project more manageable.

Combining Rewiring with Other Renovations

Planning a remodel or addition? It’s the perfect time to rewire. By combining projects, you can save on labor costs and minimize overall disruption.

How Long Does It Take to Rewire a House?

Now, I know what you’re thinking: “How long am I going to be living in a construction zone?” The answer depends on a few factors:

Factors Affecting the Duration of a Rewire

The size of your home, the extent of the rewiring, the accessibility of the wiring, and the number of electricians on the job can all impact how long the project takes. A small flat might only take a few days, while a large house could take several weeks.

Average Time for Different House Sizes

As a general rule of thumb, rewiring a small 1-bedroom flat typically takes around 5-7 days. A larger 4-bedroom house could take 10-14 days or more. But every project is unique, so it’s best to get a specific estimate from your electrician.

Minimizing Disruption During the Rewiring Process

I won’t sugarcoat it; rewiring is disruptive. There will be holes in walls, floors up, and dust everywhere. But there are ways to minimize the chaos. Work with your electrician to plan the project carefully, and consider temporary accommodation if necessary. Cover your belongings, and communicate openly with your electrician about any concerns.


So, there you have it – the inside scoop on how much to rewire a house. It’s not a cheap project, but it’s an investment in your home’s safety and value. By understanding the factors that affect the cost and choosing a qualified electrician, you can ensure a top-notch rewiring job without breaking the bank.

Listen, investing a bit of time and effort into researching and planning your home’s rewiring project can make a world of difference in managing those rewiring costs. And just imagine the satisfaction and peace of mind that comes with knowing your electrical system is in tip-top shape, ready to keep your home running smoothly for ages. You can’t put a price on that kind of assurance, if you ask me.
