A rewire is one of the most disruptive jobs you can undertake in a home, but it is also one of the most valuable. If you are asking how much does a house rewire cost, a realistic budget for a typical three-bedroom property is often between £6,000 and £10,000 in Staffordshire and the wider Midlands. The final figure depends far more on the property, its condition and the agreed specification than on the number of bedrooms alone.
A professional quotation should make clear what is included, where allowances apply and what work may be needed after the installation. That clarity matters. A low initial price can quickly lose its appeal if it excludes making good, certification, consumer-unit upgrades or the additional circuits a modern household needs.
Typical house rewire costs
The following figures are useful planning ranges for a full rewire of an occupied or vacant house. They assume a conventional installation with a new consumer unit, replacement circuits, standard sockets and switches, testing and certification. They are not fixed prices.
| Property type | Typical full rewire budget | | — | — | | One to two-bedroom flat or small house | £4,500 to £7,500 | | Typical three-bedroom house | £6,000 to £10,000 | | Four-bedroom or larger house | £8,000 to £14,000+ |
Larger, older or high-specification properties can fall outside these ranges. A substantial detached home with several reception rooms, outbuildings, electric heating, extensive external lighting or a new smart-home system may require a significantly higher budget.
These figures should also be treated differently from the cost of a partial rewire. Replacing a consumer unit, renewing a few damaged circuits or updating a kitchen and extension may solve a specific problem without requiring every cable in the property to be replaced. An electrical inspection is the sensible starting point when the scope is uncertain.
What affects how much a house rewire costs?
The biggest cost driver is access. Rewiring means getting cables safely from the consumer unit to every point that needs power, lighting or fixed equipment. In a vacant property being renovated, floorboards can be lifted, walls can be opened and rooms can be worked through in sequence. In a fully occupied house with finished décor, fitted wardrobes, tiled bathrooms and solid floors, the same work takes longer and usually involves more remedial building work.
The age and construction of the property also make a difference. Victorian and older homes can contain awkward routes, lath-and-plaster walls, unusual alterations from previous decades and hidden defects. Modern houses may be easier to route in some areas, but plasterboard walls, insulated cavities and limited loft access can create their own challenges.
The number and type of circuits
A modern installation is designed around how the property is actually used. That may mean separate circuits for the cooker, induction hob, shower, boiler, kitchen appliances, smoke alarms, outdoor supplies, garage or workshop, and upstairs and downstairs lighting. More circuits improve separation and future flexibility, but add cable, protective devices and installation time.
It is worth discussing planned changes at the survey stage. A future electric vehicle charger, solar PV and battery storage, heat pump, electric shower or garden office may need dedicated cabling or capacity considerations. Allowing for sensible future requirements during a rewire is usually more cost-effective than reopening finished walls later.
Consumer unit and protective devices
A full rewire normally includes a new consumer unit that meets current requirements for the installation. The choice of unit, surge protection, RCBO protection and the number of ways needed will affect the price. This is not an area where cutting corners is wise: the consumer unit is central to the safety, testing and protection of the whole installation.
The installer should also assess the incoming supply, earthing and bonding arrangements. If these need improvement, the work and cost should be explained clearly. In some cases, coordination with the electricity network operator may be required, particularly where supply capacity needs attention.
Specification, fittings and finishing
Standard white accessories are economical and practical, while decorative metal fittings, USB outlets, smart controls, feature lighting and premium downlights increase the budget. The same applies to external power, security lighting, data cabling, television points and ventilation equipment.
There is no single right specification. A careful design should suit the home and the people living in it. For example, extra kitchen sockets and well-positioned lighting are often more useful than expensive decorative accessories. A good contractor will help distinguish between worthwhile improvements and additions that do not offer real value.
Making good after the electrical work
Electrical contractors commonly need to lift floorboards, chase cable routes into walls and create access points. The rewire quotation should state whether it includes first-fix making good only, such as filling chases, or whether plastering, decorating, flooring repairs and final finishes are excluded.
This is one of the most common causes of budget surprises. Many homeowners arrange a plasterer and decorator after the electrical work, particularly where a property is being refurbished. For a more accurate overall budget, include those trades from the outset.
Is a full rewire necessary?
Old wiring does not automatically mean unsafe wiring, and a property does not need a full rewire simply because it has an older-style consumer unit. The decision should be based on the condition of the installation, the results of testing and whether it can safely support the way the home is used now.
Signs that warrant professional assessment include frequent tripping, damaged accessories, burning smells, cracking insulation, exposed cables, a shortage of sockets leading to extension-lead use, or a lack of suitable circuits for high-demand equipment. A property with dated wiring may also be unsuitable for planned improvements such as an electric shower, induction cooking, EV charging or solar battery equipment without upgrades.
An Electrical Installation Condition Report, known as an EICR, identifies defects and assesses the condition of the existing installation. It can show whether targeted remedial work is sufficient or whether a full rewire is the safer, more sensible long-term option. For landlords, it also provides the inspection evidence required to meet their electrical safety responsibilities.
What should a house rewire quote include?
Comparing quotations on the total price alone can be misleading. A detailed scope lets you compare like for like and gives both you and the contractor a clear plan before work begins.
A dependable full-rewire quotation should confirm the proposed circuit design, consumer unit specification, number and location of sockets, switches and light points, smoke and heat alarms, earthing and bonding work, and the type of accessories allowed for. It should also explain whether light fittings themselves are included or whether only the wiring and connection points are being provided.
Testing, certification and notification should be included where applicable. Work must comply with BS 7671, and the completed installation should be fully inspected and tested before it is put into service. You should receive the relevant Electrical Installation Certificate and test results at completion. Where domestic notifiable work applies, the appropriate Building Regulations compliance documentation should also be arranged.
Ask about the working plan as well. Will the property need to be empty? How will dust be controlled? Which rooms will be out of use, and for how long? Can temporary power be maintained during the work? Straight answers to these questions are often as valuable as the price itself.
How to budget and prepare for a rewire
Where possible, schedule a rewire before decorating, fitting a new kitchen or laying new flooring. The work is cleaner, access is better and you are less likely to pay twice for finishes. If you are buying a property, an EICR before exchange or early in the renovation planning process can help you account for electrical costs properly.
Keep a contingency for hidden issues and finishing work. A modest allowance of around 10 to 15 per cent is sensible on older properties, especially when floors, walls and previous alterations have not yet been opened up. This is not a substitute for a clear quote, but it provides breathing room if the survey cannot reveal every condition behind the fabric of the building.
At Ashware Electrical, rewires are planned around the property, the household’s present needs and the improvements it may need to support in future. That means surveying carefully, agreeing the design before work starts, installing to current standards, then testing and commissioning the completed installation properly.
A house rewire is not a purchase to rush. Choose a qualified contractor who explains the scope in plain English, documents the work and leaves you with an installation that is safe, practical and ready for the years ahead.
