How much will it cost to rewire an average-sized semi-detached house? It's an old house and we think it's about time that it was looked at by an electrician.
"It will depend on the number of rooms and points that you have in each room, but you are looking at between £2,500 and £4,000 (depending on points and finish)."
What's Included in the Cost of Rewiring a House?
A full house rewire will usually include labour and materials, but this can vary between contractors, so it's always best to check.
A rewire quote will usually include:
- Removal of existing wiring and fittings, followed by the installation of new cabling throughout the home
- Installation of new sockets and switches (typically standard white finish unless otherwise specified)
- New consumer unit installation (if required and agreed beforehand)
- Labour for first fix
- Testing and certification
Your rewiring costs won't include any painting or decorating costs, full plastering, coving/skirting boards or flooring replacement.

House Rewire Costs by Property Type
Below we take a look at the cost to rewire each property in more detail, including what influences rewiring costs along with several factors that may influence the end price:
Cost to Rewire a Bungalow
- Typical cost: £4,500 to 5,500.
- Why it costs this much: Although typically all on one level, a bungalow often has a larger floor area compared to the average flat, hence the higher rewiring costs.
- Costs can increase if: Access is difficult, extra circuits and fittings are required or the bungalow has an unusual layout.
Cost to Rewire a Flat or Maisonette
- Typical cost: £3,200 to £5,500.
- What makes it cheaper: Smaller properties = lower overall costs with fewer rooms, circuits, and shorter cable runs.
- How the price can increase: If ease of access is restricted, labour costs can rise.
Cost to Rewire a Terrace House
- Typical cost: £3,800 to £6,200.
- What can increase overall costs: Mid-terrace properties can be harder to access, which can lead to higher labour costs.
- Biggest cost driver: The condition and age of your current wiring. If a full replacement is required, expect costs to rise.
Cost to Rewire a Semi-Detached House
- Typical cost: £6,000 to £7,500.
- Why it's more expensive: Semi-detached properties typically have higher square footage than flats or terraced houses.
- Costs can rise even higher if: You choose to upgrade your consumer unit, or select premium fittings.
Cost to Rewire a Detached House
- Typical cost: £6,500 to £10,500.
- The high cost is due to: Significant floor area, more circuits, and longer cable runs.
How much does it cost to rewire a house that's around 80SQM? I am purchasing a cottage and I think it needs a full rewire. I would also like some new sockets added, and some light fixtures moved/added.
"On average, I would say that between £4,200 and £5,200 for a basic rewire on a 2/3 bed property. This would include 3 sockets per room. I would definitely advise on getting multiple quotes and all should be coming to look at the job."
External Wiring Costs
As well as the interior of your home, you may also want your electrician to fit new external wiring for you.
External wiring is commonly used for:
- Security systems
- CCTV
- Outdoor lighting
- Automated doors/gates (such as driveways or garden gates)
Adding external wiring will add around £250 to £500 to your total rewiring bill.
Electrician Costs
The average labour only cost for an electrician is usually between £200 and £400 per day, with higher rates in London and the South East due to the higher cost of living.
Many homeowners can expect a complete rewire to be carried out by a single electrician, although larger or complex homes and major renovation work may require additional tradesmen. If this is the case, then expect overall labour fees to increase accordingly.
Below we take a look at the estimated labour only fees for several locations across the UK (please note this excludes any rewiring materials, a modern consumer unit where required, or the cost of an electrical installation certificate):
| Location | Estimated Labour Cost | Compared to National Average |
|---|---|---|
| London | £3,200–£4,400 | +25% |
| Bristol | £3,200–£3,850 | +16% |
| Leeds | £2,750–£3,400 | +2% |
| Birmingham | £2,750–£3,300 | −0% |
| Manchester | £2,750–£3,300 | −0% |
| Edinburgh | £2,750–£3,300 | −0% |
| Glasgow | £2,750–£3,300 | −0% |
| Liverpool | £2,600–£3,300 | −2% |
| Nottingham | £2,500–£2,750 | −14% |

Is there an easy way of telling whether my house needs rewiring? I suspect the electrics are quite old.
"The simplest answer, honestly, is to ask for an EICR (Electrical Installation Condition Report).
If you look at the fuseboard where the meters are, is it an old type with rewirable fuses instead of circuit breakers? Can you see the cables? If they are white or grey, you might get away with a fuseboard change. Are switches and sockets cracked or showing burn marks? These are some indicators.
An EICR should cost £100 to £150 and will give you a true assessment of the condition."

How Long Does it Take to Rewire a House?
The average duration of a standard house rewire takes around 5 to 7 days to complete. However, this can depend on the extent of the individual rewiring project. For example, a full rewire of a three bedroom house can take around 5 days, whereas the rewiring process for a basic 1 bedroom flat is much quicker and straightforward.
Your timeframe can increase or decrease based on:
- Your property size and number of rooms
- Whether you need a partial or full rewire
- If you need a new consumer unit installed
- Any complications are found during the work
- The number of new power points and plug sockets
| Property Size | Average Duration |
|---|---|
| 1-bed flat | 2–3 days |
| 2-bed flat / maisonette | 3–4 days |
| 3-bed flat | 4–5 days |
| Bungalow | 3–5 days |
| 1-bed house | 2–3 days |
| 2-bed house | 3–4 days |
| 3-bed house | 4–5 days |
| 4-bed house | 5–7 days |
| 5-bed house | 6–8 days |

How long does a house rewire take? I have an old 3 bedroom and 2 bathroom Victorian house that needs rewiring and a new fuse box. I'd also appreciate any costs estimates.
"A house rewire for a three-bedroom Victorian house with two bathrooms could take around 7 to 10 days, depending on access and complexity. You're looking at roughly £6,500 to £8,000, especially if you're including a new consumer unit and modern fittings."
House Rewiring Material Costs
Material costs for electrical sockets, light fittings, switches, and other electrical components can vary significantly.
That's because there's a lot of customisability (e.g. colour, shape, material, finish) that gives you the freedom to get the look and feel that you want. However, more premium materials will increase the final price of a house rewire.
For a two-bed medium terrace house being fully rewired, if basic quality white plastic fittings are used, material costs will be around £800.
But for the same property, yet with premium quality components with a stylish finish (such as brushed steel), material costs increase to £1,500 or more.
This table outlines the cost ranges for typical rewire supplies:
| Supply | Typical Cost Range | Notes |
|---|---|---|
| Plug sockets | £2.50 – £15 each | Price depends on finish (e.g., white plastic vs designer styles) |
| Light switches | £2 – £8 each | Available as single, double, or triple gang switches |
| Light fittings | £3 – £30 each | Can range from ceiling roses to pendant or feature lights |
| Electrical wiring (50m) | £25 – £35 | 1.5mm wire is used for the lighting system, and 2.5mm is used for the power distribution |
| Consumer unit (fuse box) | £50 – £90 | Unit cost only |
| Clips and conduit | £5 – £25 | Depends on routing and wall/floor construction |

How can you make supply costs more effective?
When purchasing components for a house rewiring, it's usually more cost-effective to ask the electrician to purchase what you want. They'll usually get better prices from suppliers as they purchase from them frequently.

What's Involved in Rewiring a House?
It is not recommended to work on your own electrical system without being fully confident in your abilities, as even the smallest mistake can cause damage, personal injury or potentially worse. Even if you are capable of avoiding any costly mistakes, hiring a fully qualified electrician is a safer option. Not only can a professional ensure regulations are followed, but those registered with a competent person scheme can also self-certify their work.
With the help of MyJobQuote you can find local and registered electricians in your area, requesting a number of quotes in the process. Furthermore, the experience is fast, free and without any further obligations.
Below is a summary of what's usually involved in the rewiring process:
Before the Job
- Inspection of Existing Wiring — An electrician’s survey (around £150) can identify the condition of your current wiring, and if it needs replacing altogether or if a partial rewire is sufficient.
- Review of Fuse Box and Plug Sockets - They will also check if your fuse box needs updating with a modern consumer unit, and may also take a look at any plug sockets and switches.
- Power Turned Off — Once your electrician is ready to start work, they will ensure the power is safely isolated. Be mindful this will cause disruption around your home as you won't have any electricity unless it is turned back on for you to use.
During the Job
- Electrical Installations - If the survey finds faulty wiring, the electrician will remove the old wires and install new ones. This can involve chasing out cables or pulling them from their existing location before feeding the new wires through.
- Fixtures and Components - After wiring, sockets, switches, and light fittings are installed. Replacing old components like-for-like is usually relatively quick, but installing new fittings may take longer if any additional work is required.
After the Job
- Testing - Once the rewiring and component installation are complete, the electrician will test the entire system. This step ensures compliance with UK building regulations and uses specialized equipment.
- Certification - Finally, you will receive an official electrical installation certificate, which should be stored safely. Without this certification, selling your home later could require paying around £500 for a separate inspection by a test electrician.
What does it cost to rewire a two bed bungalow with attached garage and conservatory?
"Hi standard cost to Rewire a 2 bedroom bungalow is between £2000 to £ 2500 depending if plaster work has to be touched up if channels have been cut in walls or ceilings. It will need a look at 1st to give true quote"
Signs Your Home Needs a Rewire
If your electrical system is old, has faulty wiring, or is struggling to cope with your usage, you may need a rewire.
Here's what you should look out for:
- Your fuses are blowing or breakers are tripping regularly.
- You hear crackling or buzzing noises around electrical components or equipment.
- Lights are flickering or dimming.
- Visual signs such as discolouration or scorch marks around sockets and switches.
- You have an outdated fuse box/consumer unit or outdated wiring.
- Your electrics are over 25 to 30 years old.
- Following an EICR, your electrician recommends a rewire.
If you're planning an extension, renovation, or loft conversion you will need to contact your local building control authority. That's because there's more involved than just a full rewire, especially as you will be adding new power points and additional wiring, potentially across multiple floors.
The electrical wires in my fuseboard are red and black in colour. Is this old wiring? Do I need to have a rewire?
"Red and black cables predate 2004. So it could be fifteen years old or it could be fifty years old. It’s impossible to give advice beyond that. I have found fifty-year-old wiring in better condition than five-year-old wiring before.
Whether or not you need a rewire is impossible to advise simply based on your visual inspection. You should hire an electrician to carry out a full Electrical Installation Condition Report (EICR) to determine the suitability of your wiring for continued use."

Checklist: Hiring an Electrician to Rewire a House
Below are some questions to ask when looking to hire a professional electrician for your house rewiring:
- Do they have the right qualifications? — As well as hands-on apprenticeships, other qualifications include Level 3 NVQs in Electrotechnical Services, Installing Electrotechnical Systems & Equipment, or a Diploma in Electrical Installations.
- Are they registered with a government-competent person scheme? — Any professional electrician should be officially registered, and those who appear on a government competent person scheme, such as BESCA, Blue Flame Certification Certsure, or NAPIT hold additional benefits such as being able to self-certify their work.
- Are they fully insured? — Most tradesemen carry public liability insurance to cover personal injury or accidental property damage, while others may also hold third-party liability, which covers any building work issues.
- Have you seen evidence of previous work? — Check their MyJobQuote profile, online testimonials and their company website, or ask if they have a portfolio of work they can share.
- Do they have positive reviews? - Online presence will prove valuable for customer feedback, or again check their MyJobQuote profile for any reviews.
- Do they offer any form of guarantees? — Most electrical installations come with at least the basic guarantee of covering any immediate issues as a direct result of the initial work. However, tradesmen who provide at least a five-year guarantee can also assist if any problems arise and are likely to fix any problems at no further expense.
- Have you received more than one quote? With the help of MyJobQuote we can put you in touch with local electricians, whereby it is strongly recommended to request at least three quotes so you can gauge the best price for the work.
Can one rewire a property without pulling the floorboards up?
"You can rewire a property without pulling the floorboards up. It depends if you want the cables hidden ie. chased into the wall or surface with mini trunking. but lifting the floorboards here and there saves you a lot of chasing out walls. It really depends what way you want to go about it"

My House Has Been Flooded. Do I Need to Rewire It?
If your electrical system has been flooded, you will likely need at least a partial rewiring, which should be assessed by an electrical survey costing around £150. In cases of major flood damage, rewiring parts of the installation is often necessary, and it’s wise to consider flood-proofing measures like raising the consumer unit and sockets or using waterproof equipment.
