Full House Rewire Cost UK 2026: £3,000-9,000 for a 3-Bed Semi (Labour and Materials)
Quick Answer
A full rewire for a 3-bed semi in the UK costs £4,500-7,000 in 2026, including labour, consumer unit, first and second fix wiring but excluding decoration. A 2-bed flat costs £3,000-4,500 and a 4-bed detached costs £6,000-9,000. London adds 25-35% to these figures.
What drives the cost of a full house rewire?
A full house rewire is one of the largest electrical jobs a homeowner or landlord will ever commission. Unlike fitting a new socket or swapping a consumer unit, rewiring a property from scratch means replacing every length of cable, every circuit, and every connection point in the building. It is a substantial project that requires a qualified electrician, several days of intensive labour, and compliance with Part P of the Building Regulations.
The cost of a rewire in 2026 is driven by four main things: the size of the property, the number of circuits required, the difficulty of access, and where in the country the property is located. A small two-bed flat with timber-framed walls and an empty loft is relatively straightforward. A five-bed Victorian terrace with solid brick walls, concrete floors, and a family living in it during the works is an entirely different proposition, and the price reflects that.
This guide covers realistic 2026 prices for every property size, from a one-bed studio right up to a five-bed detached. We explain exactly what is included and what is not, which factors push prices up or down, and how to get accurate quotes from reputable electricians. Whether you are a homeowner trying to budget for a renovation, a landlord updating a rental property, or a self-employed electrician looking to benchmark your own pricing, you will find the numbers you need here. For context on daily and hourly rates for electricians specifically, the electrician hourly rate guide covers those figures in detail.
One important thing to understand from the outset: the prices in this guide cover labour, materials, and the consumer unit. They do not cover making good the decoration after the electricians have chased cables into walls and lifted floorboards. Redecoration is always a separate cost, and it can add a meaningful amount to the total project budget, particularly in older properties where cutting into walls reveals plaster that needs significant repair.
Full rewire cost by property size (UK 2026)
The table below shows the typical cost range for a full rewire by property type in 2026. These figures are for England and Wales outside of London and the South East. See the regional section below for location adjustments.
| Property type | Low estimate | High estimate |
|---|---|---|
| 1-bed flat / studio | £2,000 | £3,000 |
| 2-bed flat | £3,000 | £4,500 |
| 2-bed house | £3,500 | £5,500 |
| 3-bed semi (typical) | £4,500 | £7,000 |
| 4-bed detached | £6,000 | £9,000 |
| 5-bed detached | £8,000 | £12,000 |
A 3-bed semi typically takes 5-7 days for a team of two electricians. Larger properties take 8-12 days.
What is included in a full rewire?
When a qualified electrician quotes for a full rewire, the price should cover all of the following as standard. If a quote omits any of these, ask specifically whether it is included or whether it will be charged on top.
- New consumer unit (fuse board)
- First fix wiring to all sockets, switches and lighting
- Second fix (faceplates, pendants, switches)
- EICR electrical certificate on completion
- Notification to building control (Part P)
The consumer unit is a key part of the job. A modern unit must have RCD (residual current device) protection across all circuits, which is a requirement of the 18th Edition Wiring Regulations. Older fuse boards with ceramic fuses or basic MCBs do not meet this standard. A new consumer unit on its own costs roughly £400-800 fitted, but that is only appropriate when the existing wiring is in good condition.
The EICR (electrical installation condition report) issued on completion is the legal proof that the work meets the current standard. You will need this for building regulations sign-off, mortgage applications, insurance purposes, and when selling the property. Make sure the electrician is registered with a competent persons scheme such as NICEIC, NAPIT, or ELECSA, as this allows them to self-certify the work without requiring a separate building control inspection.
What is not included
There are several things that a rewire quote will typically not cover. Budget for these separately.
- Redecoration and making good after chasing and lifting
- Rewiring outbuildings (quoted separately)
- Smart home systems (add 30-50% to the base cost)
- Outdoor sockets and lighting (add £500-1,500)
Redecoration is often the surprise cost that catches homeowners off-guard. Electricians will typically chase channels into plasterwork to run cables, and in older properties this can leave walls in a rough state. Some homeowners choose to use the rewire as an opportunity to replaster rooms entirely, which keeps the project tidy but adds to the overall budget. If you are in any doubt, get a plasterer or decorator to look at the job after the first fix and before the second fix so you have a realistic figure for making good.
Key factors that affect rewire cost
The ranges in the table above are wide because rewiring costs vary significantly even within the same property type. Here are the main factors that move the price up or down.
Property size and number of circuits
The more circuits a property needs, the higher the material cost and the longer the job takes. A basic 3-bed semi might have 8-10 circuits (lighting upstairs and downstairs, ring mains per floor, cooker, immersion, shower). A larger property with a home office, outbuilding supply, or electric vehicle charger can have 14 or more circuits, each of which requires its own cable run back to the consumer unit.
Number of consumer units
Most properties have a single consumer unit. Properties with a large number of circuits, or those with outbuildings, sometimes require a split consumer unit or a secondary board. Each additional board adds to both material and labour costs, typically £300-600 extra.
Access difficulty
Solid-wall Victorian and Edwardian properties are harder and slower to rewire than timber-framed new builds. Chasing cables into solid brick or stone walls takes considerably more time than running cables through a suspended timber floor. Properties with concrete floors add to labour time significantly because cables must be run at high level rather than under the floor.
Whether the property is occupied
Rewiring an empty property is considerably faster and cheaper than rewiring one where a family is living in it. When the property is occupied, the electricians need to restore power to all essential circuits at the end of each working day, and they must work around furniture, children, and pets. Expect an occupied rewire to take 20-30% longer, which translates directly into higher labour costs.
Part P certification and EICR
All electrical installation work in dwellings in England and Wales falls under Part P of the Building Regulations. The cost of certification and building control notification is generally included in a reputable electrician's quote, but it is worth confirming. Using an unregistered electrician to save money on the job can result in expensive problems when you come to sell the property or make an insurance claim.
London and South East premium
Labour rates for electricians in London run 25-35% above the national average. In the South East broadly, expect to pay 15-20% above the figures in the table. This is not profiteering on the part of tradesmen. It reflects genuinely higher operating costs, including van insurance, parking permits, congestion charges, and the higher cost of living that feeds into wages for any employed team members.
Regional price variation across the UK
The figures in the cost table represent the national middle ground for England and Wales. Prices vary meaningfully by region, and understanding those differences will help you assess whether a quote is reasonable for your area.
| Region | Adjustment vs national average |
|---|---|
| London | +25% to +35% |
| South East (excl. London) | +15% to +20% |
| South West, East Anglia | Broadly in line |
| Midlands | Broadly in line |
| North of England | -5% to -10% |
| Wales | -5% to -10% |
| Scotland | -5% to -10% |
These adjustments are approximations. Within any region there will be variation between urban and rural areas. A rural property in Scotland or Wales might attract a travel surcharge if the site is remote, which can offset some of the lower regional rate. Similarly, some of the larger cities in the North, such as Manchester and Leeds, are seeing rates closer to the national average as demand for skilled trades has grown.
If you are an electrician looking to price your own work competitively, our hourly rate calculator can help you arrive at a rate that covers your costs and delivers a sensible margin. For properties with higher electrical demand, the electrical load calculator is worth using to verify that the proposed consumer unit specification is adequate.
How to get accurate quotes for a rewire
A rewire is not the sort of job where you want to go with the cheapest quote without asking questions. The difference between a good rewire and a poor one is not always visible, and a substandard job can create serious fire and safety risks. Here is how to get quotes that are meaningful and comparable.
Get at least three quotes
For a job of this size, always get a minimum of three written quotes. This gives you a realistic sense of the market rate for your property and your area. Quotes should be itemised, covering labour separately from materials, and should specify what consumer unit is being fitted, how many circuits are included, and whether certification is included in the price.
Check scheme registration
Any electrician carrying out a full rewire in England and Wales should be registered with NICEIC, NAPIT, ELECSA, or another approved competent persons scheme. You can verify registration directly on the scheme websites. This is not optional; it is what allows the electrician to self-certify under Part P. If they are not registered, you will need to involve building control separately, which adds cost and delay.
Ask about the team size and programme
Find out how many electricians will be on site and what the expected programme is from first fix to completion. A team of two working on a 3-bed semi should take 5-7 days. If an electrician is quoting for the same job as a sole trader, it may take longer, which has implications if you need to be out of the property during the works.
Clarify the making-good arrangement
Some electricians will fill chases with bonding compound before they leave. Others will do nothing beyond the electrical work. Establish this upfront so you can budget and plan for the redecoration phase. The worst situation is discovering after the job that the walls need significant repair and you have not budgeted for it.
Understand the payment terms
Most electricians on a job of this size will ask for a deposit to cover materials, typically 25-40% of the total. This is standard and reasonable. Be wary of anyone asking for more than 50% upfront or for the full amount before work begins. Agree on interim payments tied to clear milestones, such as first fix completion and second fix completion.
Frequently asked questions
How long does a full house rewire take?
A 3-bed semi typically takes 5-7 days for a two-electrician team. A 4-bed detached takes 8-12 days. Rewiring while the property is occupied takes longer because the team needs to restore power each evening and work around furniture. The job is faster and often cheaper if the property is empty. For a 5-bed property or one with a complex layout, some rewires run to two full weeks for a two-person team.
Do I need building control approval for a rewire?
Yes. A full rewire falls under Part P of the Building Regulations in England and Wales. Your electrician must either be registered with a competent persons scheme (NICEIC, NAPIT, ELECSA) to self-certify, or you must notify the local authority building control before work starts. An EICR certificate is issued on completion. Failure to comply can cause serious problems when selling the property, as solicitors routinely ask for electrical compliance certificates for any work carried out since 2005.
Can I live in the house during a rewire?
Yes, but it is disruptive. Electricians will need to cut channels in walls and ceilings, and power to different circuits will be isolated at different times. Expect a full rewire in an occupied property to take 20-30% longer. Many homeowners choose to stay elsewhere for the duration. If you do stay, make sure you have discussed with the electrician which circuits will be live each evening so that you can plan for cooking, heating, and security. A single ring main and lighting circuit kept live is the minimum most families need.
Does a rewire include the consumer unit?
A full rewire always includes a new consumer unit (fuse board). Modern consumer units are required to have RCD protection for all circuits under the 18th Edition of the Wiring Regulations. If only the consumer unit is being replaced and the existing wiring is in good condition, the cost is significantly lower at around £400-800 including labour, though the electrician will need to carry out an EICR on the existing wiring before signing it off.
How do I know if my house needs rewiring?
Signs that a property may need rewiring include wiring older than 25-30 years, round pin sockets, rubber or fabric-insulated cables visible in the loft, a fuse box with no RCD protection, persistent tripping, burning smells, and discolouration around sockets. An EICR (electrical installation condition report) will formally assess the installation and issue a graded report. A C1 or C2 result means the installation is unsafe or potentially dangerous and must be addressed. A C3 means improvement is recommended. If you are buying a property, commission an EICR before exchange so you can factor any required work into your offer.
Is rewiring a house covered by insurance?
Standard home insurance does not cover the cost of rewiring unless the damage is caused by an insured event like fire. Some insurers will not renew policies or will apply exclusions to properties with outdated wiring. Having a fresh rewire and a current EICR can reduce your premiums, as insurers view modern wiring with RCD protection as significantly lower risk. If you are a landlord, outdated wiring can invalidate your landlord insurance policy entirely, particularly if a fire is later attributed to the electrical installation.
