How Much Does a House Rewire Cost in 2026? Room by Room Prices, Labour Rates and Consumer Unit Upgrades
If you are researching house rewire cost UK figures in 2026, you are probably facing a real scenario such as buying a 1970s three bed house with outdated electrics and quotes landing anywhere between £6,500 and £10,000. That range is typical today, and the variation comes down to access, specification and how much making good is required. A full rewire is one of the most significant electrical jobs in a home. It is disruptive, regulated and not cheap, but done properly it improves safety, capacity and futureproofing.
This guide breaks down realistic UK rewire costs, room by room pricing, labour rates, and the cost of upgrading a consumer unit. It also covers timelines, regulations and the common pitfalls that catch homeowners out.
Average House Rewire Cost in 2026
Rewiring costs vary widely depending on property size, layout, access and finish. A clear, stripped back renovation is always cheaper than working around occupied rooms with finished plaster and flooring.
Typical full rewire costs in 2026 are:
- 1 bed flat, £3,500 to £5,500
- 2 bed house, £4,500 to £7,000
- 3 bed house, £6,000 to £9,500
- 4 bed house, £8,000 to £13,000
- Large or high spec homes, £12,000 to £20,000 plus
These figures usually include first fix and second fix labour, standard white accessories, and a new consumer unit. They do not always include extensive making good, plastering, or premium finishes.
If access is straightforward and the property is empty, expect the lower end. If the house is occupied or has solid floors, tight voids or high end fittings, expect the upper end or beyond.
Detailed Cost Breakdown
| Cost Element | Typical Price Range | Notes |
|---|---|---|
| Labour | £2,500 to £6,000 | Based on size, team and duration |
| Materials and cabling | £1,500 to £3,500 | Includes wiring, back boxes, accessories |
| Consumer unit | £500 to £1,200 | Varies based on RCD or RCBO setup |
| Testing and certification | £150 to £400 | Electrical Installation Certificate included |
| Making good and plastering | £500 to £2,500 | Highly variable depending on damage |
What Actually Gets Replaced in a Full Rewire
A proper rewire is not just swapping a few sockets. It involves replacing or upgrading core infrastructure throughout the property.
- All electrical cabling, usually twin and earth
- Socket outlets and switches
- Lighting circuits and fittings
- Consumer unit with modern protection
- Earthing and bonding to current standards
- Smoke and heat alarm circuits where required
First Fix Explained
This stage involves all hidden work. Electricians run cables through ceilings, under floorboards and inside wall chases. Back boxes are installed and routes are planned for future access. At this point the system is not live.
Second Fix Explained
Second fix is the visible finish. Sockets, switches, light fittings and the consumer unit are installed. The system is energised, tested and certified.
Modern Safety Upgrades
Rewiring also brings the installation up to current standards. This includes correct bonding to gas and water services, installation of interlinked smoke alarms, and protection against electric shock and overload through modern circuit protection.
Room by Room Rewire Costs
Breaking costs down by room helps you understand where your budget is going and allows partial rewires where appropriate.
| Room | Typical Cost Range | Notes |
|---|---|---|
| Living room | £600 to £1,200 | Sockets, lighting, TV points |
| Kitchen | £1,500 to £3,500 | High load circuits, appliances |
| Bedroom | £500 to £1,000 per room | Sockets, lighting, optional data points |
| Bathroom | £700 to £1,500 | Zoned fittings, extractor fan, heater |
| Hall and stairs | £500 to £1,000 | Lighting circuits, smoke alarms |
| Garage or external | £500 to £2,000 | Power, lighting, potential armoured cable |
Living Room Details
A typical living room will include 6 to 10 double sockets, a lighting circuit, and often TV, satellite or data points. Many homeowners now add dimmer circuits or wall lights, which increase cost slightly.
Kitchen Requirements
Kitchens often require multiple dedicated circuits. These include cooker, oven, hob, dishwasher, washing machine and fridge. Expect at least 8 to 12 sockets plus spurs for fixed appliances. This is why kitchen rewires are significantly higher in cost.
Bedroom Setup
Bedrooms typically include 4 to 8 sockets, a lighting point and sometimes USB outlets or Ethernet cabling for home working setups.
Bathroom Safety Zones
Bathrooms must comply with strict zoning rules. Only certain fittings are allowed near water sources, and circuits must be RCD protected. Extractor fans and electric showers add to the cost.
Labour Rates for Electricians in 2026
Labour makes up a significant portion of rewire costs. Rates vary by location and experience.
- Day rate for qualified electrician, £250 to £400
- Apprentice or mate, £120 to £200 per day
- Hourly rate for smaller jobs, £45 to £80
Team Size and Impact on Cost
A two person team will complete a three bed rewire faster than a single electrician, often within 5 to 7 days instead of 8 to 10. While the daily labour cost is higher, the shorter duration can reduce overall disruption and secondary costs such as accommodation.
Occupied vs Vacant Properties
Occupied homes take longer. Electricians must protect furniture, lift and refit flooring carefully, and often work in phases. This can add 20 to 40 percent to labour time compared to an empty property.
Regional Cost Differences
London and the South East typically sit at the top end of pricing. A three bed rewire that costs £7,000 in the Midlands may reach £9,000 or more in London. Northern England and Wales often sit slightly lower, although rural access and travel time can offset savings.
Consumer Unit Upgrade Costs and Options
Most rewires include replacing the consumer unit, which is essential for meeting modern safety standards.

Typical costs for a new consumer unit in 2026:
- Standard dual RCD board, £500 to £800
- RCBO board, £700 to £1,200
- High spec or surge protected boards, £900 to £1,500
RCD vs RCBO Explained
An RCD protects multiple circuits and will shut down a group if a fault is detected. An RCBO protects individual circuits, so only the affected circuit trips. This makes fault finding easier and reduces disruption, which is why RCBO boards are increasingly common.
Most installations must comply with BS 7671 wiring regulations. You can review the framework via the IET wiring regulations and guidance from NICEIC.
Partial Rewire vs Full Rewire
Some homeowners attempt to save money by rewiring only part of the house. This can work in specific situations, but it has limits.
| Type | Pros | Cons | Typical Cost | Long Term Impact |
|---|---|---|---|---|
| Partial rewire | Lower upfront cost | Mixed wiring systems, future issues | £1,500 to £5,000 | Often requires full rewire later |
| Full rewire | Complete upgrade, safer | Higher initial cost | £4,500 to £13,000 | Long lasting solution |
When a Partial Rewire Works
If wiring is relatively modern and tested as safe through an EICR, rewiring a kitchen or extension area can be reasonable.
When It Does Not
Older properties with rubber insulation, aluminium wiring or overloaded circuits are rarely suitable. Mixing systems often leads to nuisance tripping and certification complications.

Planning a Rewire Without Major Disruption
Disruption is often the biggest concern. Floors come up, walls are chased, and power is off for periods.
Proper planning makes a significant difference. A phased, room by room schedule can help if you are living in the property during works.

Typical Rewire Timeline
- Initial survey and quote
- Design and layout planning
- First fix cabling
- Inspection if required
- Second fix installation
- Testing and certification
- Making good and decoration
UK Regulations and Certification
Electrical work in UK homes is controlled under Part P of the Building Regulations. Most rewires are notifiable works.
- Work must be carried out by a competent person
- Installation must meet BS 7671 standards
- You should receive an Electrical Installation Certificate
- Building Control notification is required unless the electrician is registered with NICEIC or NAPIT
Certification and Testing
At the end of the job you should receive an Electrical Installation Certificate confirming the work meets standards. Many electricians will also recommend an EICR after several years to reassess condition.
Building Control vs Self Certification
If your electrician is registered with schemes such as NICEIC or NAPIT, they can self certify the work. If not, you must notify Building Control before work begins, which adds cost and delay.

Additional Costs to Factor In
Plastering and Making Good
Chasing walls creates damage that must be repaired. Costs range from £500 to £2,500 depending on extent and finish required.
Decoration Costs
Repainting walls and ceilings is often necessary after a rewire. Budget £300 to £2,000 or more depending on property size.
Optional Upgrades
Extras such as downlights, USB sockets, smart switches or garden lighting can quickly add hundreds or thousands to the total.
Futureproofing Your Rewire
A rewire is the best time to plan for future electrical demand.
Recommended Circuits
Modern homes typically benefit from separate circuits for kitchen appliances, sockets upstairs and downstairs, lighting, and dedicated supplies for high load items.
Electric Vehicle Preparation
Installing a dedicated circuit or even just running cabling for a future EV charger can cost £200 to £600 during a rewire, compared to over £1,000 later.
Allowance for High Load Devices
Induction hobs, electric boilers and heat pumps all place higher demand on systems. Planning capacity now prevents costly upgrades later.
Smart and Data Infrastructure
Adding Ethernet cabling, smart lighting wiring or security systems during a rewire is far cheaper than retrofitting.

Common Mistakes to Avoid
- Under specifying socket numbers, which leads to over reliance on extension leads and clutter
- Choosing the cheapest quote without checking qualifications, which can result in unsafe work
- Not upgrading the consumer unit, leaving the system non compliant
- Poor lighting layout planning, causing dark areas or awkward switch positions
- Trying to live in the property without phasing, increasing stress and delays
- Skipping certification, which creates problems when selling or insuring the property
What Can Go Wrong During a Rewire
Even well planned projects can encounter issues.
Hidden Structural Problems
Once floors and walls are opened, issues such as rotten joists or unsafe previous alterations can appear.
Asbestos Risks
Older homes may contain asbestos in ceilings or wall coatings. Specialist removal may be required before work continues.
Solid Wall Challenges
Properties with solid brick or concrete walls are harder to chase for cables, increasing labour time and cost.
Earthing Upgrades
Older homes may lack adequate earthing. Upgrading earth rods or bonding systems can add unexpected costs.
Supply Capacity Issues
If the incoming electrical supply is insufficient, your Distribution Network Operator may need to upgrade it.
How Long Does a House Rewire Take
Timeframes depend on size and access.
- 1 to 2 bed property, 3 to 5 days
- 3 bed property, 5 to 10 days
- 4 plus beds, 1 to 3 weeks
This excludes plastering and decorating, which may extend the total project time. Larger teams can reduce duration, while occupied homes usually extend it.
Practical Checklist Before Starting a Rewire
- Get at least two to three detailed quotes
- Confirm NICEIC or equivalent registration
- Agree socket and lighting layouts in writing
- Plan furniture placement beforehand
- Decide on consumer unit type
- Confirm plastering and making good responsibilities
- Arrange temporary accommodation if needed
FAQs
How do I know if my house needs a full rewire?
Signs include frequent tripping, old fuse boards, rubber or fabric insulated cables, and a lack of sockets. Properties over 25 to 30 years old that have not been updated often require rewiring. An EICR report will confirm condition and highlight safety issues.
Is a rewire covered by insurance?
Most policies do not cover upgrades. They may cover damage caused by faults but not replacement of outdated wiring. Always check the details of your cover.
Can I live in my house during a rewire?
It is possible but disruptive. You may lose power for periods and deal with dust and noise. Many people either move out temporarily or phase the project room by room.
Do I need planning permission for a rewire?
No planning permission is required, but Building Regulations Part P must be followed. Certification is mandatory.
Does a rewire add value to a property?
It improves safety and buyer confidence. While it may not add direct value pound for pound, it helps avoid price reductions during a sale.
How much does a rewire cost per square metre?
A typical range is £60 to £120 per square metre depending on specification and access. Smaller homes often have a higher per metre cost due to fixed labour elements.
Can I rewire a house myself?
Legally you can, but it must comply with Part P and be inspected by Building Control if you are not registered with a competent person scheme. In practice, most homeowners use a qualified electrician due to safety and certification requirements.
Final Thoughts
A house rewire is a major investment, but it is one that directly affects safety, usability and long term value. Costs in 2026 reflect rising material prices and higher expectations for electrical capacity.
Take time to plan properly, choose a qualified electrician, and think ahead to future needs. A well executed rewire should last decades.
