Frequently Asked Questions

Can you rewire a house in stages?

Yes, rewiring a house can be done in stages or room by room, especially in larger properties or if you’re living in the home during the process. This approach minimises disruption and allows you to spread the cost over time. However, it’s important to plan each stage carefully with your electrician to ensure safety and compliance throughout the project.

Do I need a qualified electrician to rewire my house?

Yes, rewiring a house is a complex and potentially hazardous task that should only be carried out by a qualified, certified electrician. In the UK, electrical work must comply with Part P of the Building Regulations, and only registered electricians can self-certify their work. Hiring a professional ensures the rewiring is safe, legally compliant, and covered by insurance.

Do I need to rewire my house to sell it?

While it’s not a legal requirement to rewire your house before selling, outdated or unsafe wiring can lower your property’s value and deter buyers. Many mortgage lenders require an Electrical Installation Condition Report (EICR) as part of the survey process. If the report highlights serious issues, buyers may request a rewire as a condition of sale. Addressing electrical problems beforehand can make your home more attractive and prevent delays.

Does a rewire add value to your house?

Yes, a professional rewire can increase your home’s value by ensuring it meets modern safety standards and is future-proofed for technological advancements. Buyers are often willing to pay more for a property with up-to-date wiring, as it reduces the risk of electrical faults and the need for costly repairs. Additionally, a rewire can improve energy efficiency and support smart home integrations.

Does house insurance cover rewiring?

Most standard home insurance policies do not cover the cost of rewiring unless the work is required due to sudden, accidental damage (e.g. a fire or flood). However, if outdated wiring causes a fire or electrical fault, your insurance may cover the repairs, provided the wiring was deemed safe at the time of the policy. Always check with your insurer and consider upgrading your wiring proactively to avoid voiding your cover.

Does rewiring a house save energy?

Yes, rewiring can improve your home’s energy efficiency. Old or faulty wiring can cause voltage drops and energy waste, leading to higher electricity bills. Modern wiring, combined with an upgraded consumer unit, ensures your electrical system operates efficiently. Additionally, rewiring allows for the installation of energy-saving technologies, such as smart meters and LED lighting systems.

How disruptive is a house rewire?

Rewiring a house can be disruptive, but the level of disruption depends on the property’s age and layout. In most cases, electricians can minimise damage by accessing wiring through existing routes, such as floorboards or loft spaces. However, some chasing of walls may be necessary. You can usually live in the house during the rewire, but it’s advisable to plan for temporary inconveniences, such as power outages in specific areas. Your electrician will discuss the process with you beforehand to manage expectations.

How much does it cost to rewire a house?

The cost to rewire a house depends on the property’s size, age, and accessibility. For an average 3-bedroom home in Sutton or South London, prices typically range from £3,500 to £6,000. Larger properties or those with complex layouts may cost more. A fixed-price quote will be provided after a thorough assessment of your home’s electrical needs.

Do smoke alarms test themselves?

Most modern smoke alarms include a self-testing feature that checks the battery and sensor functionality automatically. However, you should still manually test them monthly by pressing the test button. Replace batteries annually (or as recommended) and replace the entire unit every 10 years.
