Electrical rewiring is a critical upgrade for many homes in London, ensuring safety, compliance, and efficiency in ageing properties. At RCD Electrical, North London’s trusted specialists, we know that rewiring is a major investment and often a source of many questions—especially around cost.
While it’s difficult to quote a fixed price without an assessment, this guide breaks down the key factors that influence the cost of a full house rewire and provides practical advice on budgeting and planning your project.
Why Is Electrical Rewiring Essential?
The electrical system in any property naturally degrades over time, especially in older buildings where outdated wiring can pose serious safety risks. In fact, electrical faults are among the leading causes of house fires across the UK.
An Electrical emergency —such as sudden power loss, sparks from sockets, or burning smells—signals urgent attention and often points to the need for comprehensive rewiring.
A full rewire brings your property in line with the latest wiring regulations (BS 7671), significantly improving safety and allowing your home to accommodate modern electrical devices and appliances.
What Affects the Cost of Rewiring a House?
1. Size and Complexity of the Property
Larger homes naturally require more materials and labour. The wiring needed for a compact flat will be far less extensive than that for a multi-bedroom detached house with several floors and additional features like garages or outbuildings.
Complex layouts and older buildings with difficult access points can also increase installation time.
2. Age and Condition of Existing Wiring
Older properties often have antiquated wiring systems—like rubber-insulated cables—that need careful removal and disposal. If your home has outdated fuse boxes or signs of damage, rewiring becomes more complex.
Additionally, if asbestos is present around electrical installations, specialist removal is required, which affects costs and timelines.
3. Quality and Type of Materials and Fixtures
Choosing between standard fittings and premium or smart technology can influence overall costs. For instance, USB-enabled sockets, dimmer switches, or smart lighting require more expensive components and skilled installation.
Using high-quality copper wiring and modern consumer units with Residual Current Devices (RCDs) ensures safety but might add to the investment compared to basic setups.
4. Labour Costs Specific to London
Electricians’ hourly rates in London tend to be higher than elsewhere in the UK due to living costs and demand. This is an important factor to keep in mind when budgeting for your rewiring.
5. Additional Work and Services
Sometimes rewiring uncovers other necessary jobs, such as:
-
Repairing plaster and redecoration after cable runs
-
Upgrading or replacing consumer units and fuse boxes
-
Obtaining necessary certifications such as Electrical Installation Certificates (EIC) or Electrical Installation Condition Reports (EICR)
-
Incorporating new circuits for modern appliances or smart home systems
Typical Timelines for Rewiring Projects
The duration of a full house rewire depends on property size and complexity. Smaller flats may be completed within a week, whereas larger homes could take several weeks. Planning and clear communication with your electrician can help minimise disruption.
Hidden Costs You Should Be Aware Of
Beyond the visible rewiring work, there may be additional expenses including:
-
Specialist removal of hazardous materials like asbestos
-
Plastering and decorating repairs after the wiring work
-
Costs related to certification and safety inspections
-
Unexpected repairs found during the installation process
Discussing these possibilities upfront with your electrician can prevent surprises later.
