For most UK homes, a full house rewire is a major job, so it is sensible to budget carefully before you invite electricians round. As a broad 2026 guide, many full rewires fall somewhere between £4,000 and £12,000, with small flats costing less and larger, older or occupied homes costing more.
The exact figure depends on the size of the property, how easy it is to access floors and walls, how many sockets and light points you want, and whether the home is empty or lived in during the work. Labour rates also vary by location, which is why HaMuch helps you compare real, local electrician prices rather than relying on one vague national average.
Typical house rewiring costs in the UK
The table below gives sensible planning ranges for a standard full rewire in 2026. These figures are not a substitute for a written quote, but they should help you understand whether an estimate is in the right ballpark.
| Property type | Typical full rewire cost | Typical timescale |
|---|---|---|
| 1-bedroom flat | £3,000 to £5,000 | 3 to 5 days |
| 2-bedroom house | £4,000 to £7,000 | 5 to 7 days |
| 3-bedroom house | £5,500 to £9,000 | 7 to 10 days |
| 4-bedroom house | £7,500 to £13,000 | 10 to 15 days |
| 5-bedroom house or larger | £10,000 to £18,000+ | 2 to 3 weeks or more |
A very basic rewire in an empty property may come in near the lower end. A lived-in home with lots of furniture, solid floors, extra sockets, smart controls, outbuildings or high-end finishes can cost significantly more.
Always check whether the quote includes VAT, certification, the consumer unit if it needs replacing, and any making good to walls or ceilings. A cheaper quote can become expensive later if key items are excluded.
Why location changes the cost
A house rewire is labour-heavy. Materials matter, but the number of days on site, the number of electricians needed, parking, access and local demand all affect the final price.
For example, you may see different day rates when comparing London electrician rates, Birmingham electrician rates and Manchester electrician rates. That does not mean one electrician is automatically better or worse. It simply means the local cost of doing the job can differ.
If you are budgeting for a property in the capital and want a more detailed local breakdown, HaMuch has a separate guide to rewiring costs in the capital.
What does a full house rewire usually include?
A full rewire normally means replacing old or unsafe wiring across the property, rather than just changing sockets or light fittings. The electrician will assess the existing installation, plan new circuits, install new cabling where needed, fit accessories and test the system at the end.
In plain English, a full rewire often includes:
- Removing or disconnecting outdated wiring where appropriate
- Installing new cables for lighting, sockets, cooker circuits and other fixed electrical points
- Replacing sockets, switches and light fittings where agreed
- Installing or upgrading the consumer unit if required
- Checking earthing and bonding arrangements
- Testing the finished installation and providing the correct electrical certificate
Some quotes include basic patching after walls are chased. Others leave plastering and decorating to a separate trade. This is one of the most important things to confirm before you choose a quote, as making good can add hundreds or even thousands of pounds depending on the condition of the property.
Main factors that affect your rewire quote
Property size and layout
A larger home usually needs more circuits, more cable, more sockets and more time. But layout matters too. A compact three-bedroom terrace may be simpler than a spread-out bungalow with extensions, converted loft space and a detached garage.
The number of floors also matters. Lifting floors, running cable routes and working around finished rooms all take time. Older homes can be harder to predict because floorboards, wall construction and previous DIY work may not be obvious until the job starts.
Whether the home is empty or occupied
An empty property is normally easier and faster to rewire. Electricians can lift floors, turn power off, move through rooms and work without having to protect furniture or keep parts of the home usable.
A lived-in rewire is more disruptive. It may need to be done in stages, with temporary power arrangements and extra care around belongings. That extra time can increase labour costs.
Number of sockets, switches and light points
Modern households use far more electrical items than older homes were designed for. Adding more sockets during a rewire is often sensible, because it is much easier to plan them while the walls and floors are already being worked on.
If you only need a smaller job, such as adding one or two extra outlets, see HaMuch’s guide to the cost of installing a new electrical socket. For a full rewire, extra points will usually be priced as part of the wider scope.
Access to floors, walls and ceilings
Some properties are simply easier to work in than others. Suspended timber floors, accessible loft spaces and straightforward room layouts can reduce time on site. Solid floors, tiled areas, fitted furniture and decorated walls can make the job slower and more delicate.
If a room has expensive finishes, such as fitted wardrobes, bespoke joinery or recently decorated walls, tell the electrician before they quote. They may need to adjust the method or allow for extra care.
Specification and extras
A basic rewire covers essential circuits and standard fittings. Many homeowners choose to add extras while the work is being done, such as outdoor power, extra lighting, smoke alarms, data cabling, electric vehicle charger preparation or smart home wiring.
These upgrades can be worthwhile, but they should be priced clearly. Ask the electrician to separate must-have safety work from optional improvements so you can compare quotes fairly.
Do you actually need a full rewire?
Not every electrical problem means the whole house needs rewiring. Sometimes a repair, consumer unit upgrade or partial rewire is enough. The right starting point is usually an inspection by a qualified electrician.
Common signs that a property may need rewiring include frequent tripping, old rubber or fabric-covered cables, scorch marks around sockets, buzzing switches, flickering lights, too few sockets, damaged accessories or evidence of poor DIY electrical work.
Age is also a clue, but not proof. A home that has not been rewired for several decades may need major work, especially if it has been extended or altered over time. However, a well-maintained installation can last a long time if it has been tested and upgraded properly.
For landlords, electrical safety is not optional. In England, private landlords must have electrical installations inspected and tested at least every five years, according to government guidance on electrical safety standards. If you need an inspection first, HaMuch’s guide to EICR electrical safety certificate costs explains what to expect.
Full rewire vs partial rewire
A partial rewire can make sense if only one area is unsafe or if you are renovating in stages. For example, you might rewire a kitchen extension now and leave the rest of the property until later.
However, partial rewires are not always cheaper in the long run. Electricians may need to revisit the same areas, reopen floors or walls, and reconnect new work to older circuits. If the whole installation is ageing, doing everything at once can be cleaner, safer and easier to certify.
Here is a simple way to think about it:
| Option | Best suited to | Potential drawback |
|---|---|---|
| Full rewire | Older homes, full renovations, unsafe installations | Higher upfront cost and more disruption |
| Partial rewire | One unsafe area, extensions, staged renovations | Can cost more overall if repeated later |
| Inspection first | Unclear condition, property purchase, rental checks | May reveal more work is needed |
If you are not sure which option is right, ask for an inspection and a written recommendation. A good electrician should explain the reason for the proposed work in plain English.
What to ask before accepting a rewiring quote
A rewire quote should be detailed enough for you to compare it with others. If one quote is much lower, check what is missing before assuming it is the best deal.
Ask these questions before you agree to the work:
- Does the quote include labour, materials and VAT?
- Is the consumer unit included if it needs upgrading?
- How many sockets, switches and light points are included?
- Will the electrician provide the correct electrical certificate?
- Is making good to walls and ceilings included or excluded?
- How long will the job take, and will the power be off throughout?
- What happens if hidden problems are found once floors or walls are opened?
It is also worth asking who will be on site. Larger jobs may involve more than one electrician or an electrician and an apprentice. That can be perfectly normal, but the person responsible for signing off the work should be clear.
How to keep rewiring costs under control
The best way to avoid surprise costs is to plan properly before work begins. Walk through every room and decide where you want sockets, switches, lights and appliance points. Think about future use too, not just what you need today.
For example, a spare bedroom may later become a home office. A garden may later need lighting or power. A kitchen renovation may need more dedicated circuits than the existing layout has. Planning these things during the rewire is usually cheaper and neater than adding them afterwards.
At the same time, avoid adding extras just because they are possible. A clear brief helps electricians quote accurately and helps you compare like with like.
Frequently asked questions
How much does it cost to rewire a 3-bedroom house? A typical 3-bedroom house rewire often costs around £5,500 to £9,000, depending on the property’s condition, access, location and the number of sockets and light points required.
Is rewiring a house worth it? Yes, if the existing wiring is unsafe, outdated or unsuitable for modern use. It can improve safety, make the property easier to insure or sell, and reduce the need for repeated electrical repairs.
Can I live in my house during a rewire? Sometimes, but it is disruptive. Floors may be lifted, walls may be chased and power may be off for periods. If you can stay elsewhere during the messiest stages, the job is often easier and quicker.
Do I need a certificate after a rewire? Yes. After a full rewire, you should receive the appropriate electrical installation certificate. In many cases, the work must also be notified under building regulations by a competent person scheme member or through building control.
How often should a house be rewired? There is no fixed rule for every home. Many installations can last for decades, but condition matters more than age. If the wiring is old, damaged or has not been inspected for many years, arrange an electrical inspection.
