House Rewiring Process Overview
Understanding the full rewiring process can help you plan your schedule, protect your belongings, and avoid surprises.
Step 1: Initial Electrical Survey
An inspection is conducted by our electrician to assess the current condition of the wiring and determine the scope of the project.
Step 2: Design and Planning
This stage involves deciding:
- Where sockets, switches, and lights will go
- Whether new appliances or systems (like underfloor heating or CCTV) need wiring
- How to minimise disruption during the process
Step 3: Disconnect and Remove Old Wiring
Power is turned off, and outdated wiring is safely removed. This can be quite invasive, especially in finished homes.
Step 4: Install New Wiring and Accessories
New cables, consumer units (fuse boxes), sockets, and light fittings are installed to meet current electrical standards.
Step 5: Making Good
Once the work is completed, the electrician may patch up any holes or plasterwork left behind. However, full redecorating is usually your responsibility.
Cost Factors of House Rewiring
One of the most common questions homeowners ask is: “What is the cost of rewiring a house?” The truth is, the price can vary significantly depending on several factors.
1. Size of the Property
The larger your house, the more materials and labour will be needed. For example:
- 1-bedroom flat: £1,000 – £2,000
- 3-bedroom house: £2,500 – £3,500
- 5-bedroom house: £4,000 – £5,500+
These are general estimates; the final cost depends on your location and specific project needs.

2. Age and Condition of Existing Wiring
Older properties often have outdated or unsafe wiring, which requires more time and care to remove and replace. Properties built before the 1970s typically have wiring that no longer meets current safety standards.
3. Accessibility and Layout
If walls need to be broken into or if the wiring runs through difficult-to-reach places like lofts, basements, or under floors, expect to pay more for the added labour.
4. Fixtures and Upgrades
Adding extra sockets, energy-efficient lighting, or smart home tech will increase costs but can improve functionality and future-proof your home.
FAQs About House Rewiring
How do I know if my house needs rewiring?
Some tell-tale signs include:
- Frequent fuse blowouts
- Flickering lights
- Burning smells from sockets
- Discoloured switches
- Buzzing or crackling noises from outlets
- A consumer unit (fuse box) without modern circuit breakers
What’s the average cost of rewiring a 2-bedroom house?
In the UK, a full rewire for a 2-bedroom house generally costs between £2,000 and £3,000, depending on location, layout, and material choice.
Can I live in my house during the rewiring process?
Yes, but it’s not always comfortable. There will be dust, noise, and temporary power outages. Many people choose to move out while the work is ongoing, especially if children or pets are involved.
How long does a full house rewire take?
Most rewiring jobs take 3 to 8 working days. Complex properties or custom designs may take longer.
Final Thoughts: Is House Rewiring Worth It?
Absolutely. While the cost of rewiring can seem steep at first, it’s a long-term investment in your property’s safety and efficiency. Modern wiring supports today’s high electricity demands, reduces the risk of fire, and can even increase your home’s market value.
