What does a full house rewire involve?
Rewiring is not simply replacing a few cables. It is a comprehensive electrical upgrade that ensures your home is safe, efficient, and compliant with modern UK wiring regulations. A full rewire will usually include:
- New consumer unit (fuse box): Modern units include residual current devices (RCDs) for improved safety.
- Sockets and switches: You’ll choose the number, locations, and finishes – from basic white plastic to premium brushed metal designs.
- Lighting: Both the number of light points and the types of fittings are considered.
- Additional features: Many rewires also include outside lights, bathroom fans, kitchen extractors, smoke alarms, burglar alarms, shaver points, central heating wiring, or even dedicated circuits for showers and pumps.
Because of the complexity, a professional electrician will carry out a full survey of your property before providing a quotation. This ensures the estimate reflects your needs, the layout of your home, and any safety issues.
Factors that affect the cost of a house rewire
The cost to rewire a house in the UK is influenced by several factors.
First, accessibility plays a huge role. Electricians need to run cables under floors, through ceilings, and up and down walls to reach sockets and switches. If your property is empty, with clear access to voids and wall space, the job is much quicker and less expensive. A lived-in property, particularly one with finished decoration and furniture, takes longer to work on and usually costs more.
Second, how the wiring is concealed will change the price. The cheapest option is to use surface-mounted trunking, but this is visually less appealing. Most homeowners prefer cables to be chased into the walls, plastered over, and redecorated afterwards. This adds cost but delivers a much cleaner finish.
Third, the number and type of fittings make a difference. For example, installing a higher number of sockets, premium finishes, or smart fittings will increase the overall cost compared to a more basic installation.
Finally, regional variation must be considered. Labour costs are higher in London and the Southeast than in the North of England, Scotland, or Wales, so the same job may be 15 to 20% more expensive depending on where you live.
Why it’s best to rewire an empty house
If you are planning a rewire, it’s worth considering the timing. Rewiring a home is far easier and cheaper when the property is empty. Electricians can move freely, chase walls, and run cables without worrying about damaging décor or moving furniture.
In a furnished home, additional time is needed to protect surfaces, clear working areas, and make good afterwards. For this reason, many homeowners choose to combine a rewire with a renovation project, tackling both jobs at once to save money and disruption.
Certification and compliance
A full house rewire must comply with Part P of the Building Regulations. Only a qualified, certified electrician can legally carry out this work. At the end of the job, you should be provided with an Electrical Installation Certificate confirming that your home’s wiring meets UK safety standards.
This certificate is essential not only for peace of mind but also for insurance purposes and when selling your property. Without it, you may struggle to prove that the electrical work was carried out safely and correctly.
Regional rewire cost variations
The average costs listed above are based on prices submitted by UK homeowners, but it’s important to remember that where you live can influence the final figure.
- London and the Southeast: Expect to pay towards the top end of the scale due to higher labour costs.
- North of England, Wales, and Scotland: Typically, costs are lower, although rural areas may see higher call-out charges.
- Cities vs. rural areas: Urban electricians may be more expensive per hour, but rural jobs often involve longer travel times.
How to save money on a house rewire
Although rewiring is a major expense, there are ways to keep costs under control. For example, planning the layout of sockets and switches in advance reduces changes during installation. Choosing standard fittings instead of premium designer options can also cut costs significantly.
Another cost-saving tip is to schedule the rewire alongside other building work, such as plastering or redecorating. This means the disruption happens once, and you may benefit from shared labour costs. Finally, always get multiple quotes from local electricians. Comparing at least three certified professionals ensures you’re paying a fair price and getting value for money.
