If your home is over 30 years old and has never had its electrics updated, it might be time to consider a full house rewire. Faulty wiring is not just inefficient; it can be dangerous.
In 2025, more homeowners across the UK are choosing to invest in full rewires to improve safety, boost energy efficiency, and futureproof their homes for modern electrical demands. But how much does a rewire cost, and is it really worth the investment?
In this guide, we'll break down the average cost of rewiring a house in the UK in 2025, the signs your home may need one, and why it’s one of the most important upgrades for older properties.
Why Would You Need a Full House Rewire?
1. Safety First
Old or faulty wiring can be a serious fire hazard. Outdated systems weren’t designed to handle today’s energy demands, leading to overloaded circuits and increased risk of electrical faults. Rewiring ensures your home is up to modern standards and complies with current building regulations and safety codes.
2. Energy Efficiency
Modern rewires often include upgrades to more energy-efficient lighting and the option to install smart home features or EV charging points. A rewire is the first step towards a more sustainable and energy-smart home.
3. Better Functionality
Many older homes have limited plug sockets or circuits that are no longer sufficient for modern living. A rewire can be tailored to your lifestyle, adding more sockets, USB charging points, and optimised lighting throughout.
4. Home Renovation Opportunity
Planning a renovation? It's often more cost-effective to carry out a rewire while walls and floors are already being worked on. If you're upgrading your kitchen, adding an extension, or converting a loft, rewiring might be necessary anyway.
Signs Your Home May Need Rewiring
Fuse box with ceramic fuses or no RCD protection
Light switches or sockets that are hot to the touch
Frequent blown fuses or tripped breakers
Flickering lights
Old rubber or fabric-insulated cabling
Lack of grounding or outdated two-pin sockets
If you're unsure whether your home requires a full or partial rewire, it's always best to get a professional electrical inspection.
How Much Does a House Rewire Cost in 2025?
The cost of rewiring a house in the UK in 2025 depends on a few key factors:
Property size (1-bed flat vs. 4-bed house)
Location (London typically costs more than regional towns)
Access and complexity (furnished homes, listed buildings, etc.)
Upgrades included (LED lighting, smart home tech, extra sockets)
Here are rough price estimates:
1-bed flat: £3,000 - £4,500
2-bed house: £4,000 - £6,000
3-bed house: £6,000 - £8,000
4-bed house: £8,000 - £10,000+
These estimates include labour, materials, and certification. Always request a bespoke quote from a qualified electrician to get an accurate figure.

What's Generally Included in a Full Rewire?
Replacing all old cabling with modern, insulated wiring
New consumer unit (fuse box) with RCD protection
Installing new sockets, switches, and light fittings
Earthing and bonding to comply with regulations
Electrical safety certificate upon completion
Depending on your needs, you might also want:
Smart home integrations
USB plug sockets

EV charging point installation
How Long Does It Take?
Rewiring typically takes:
1-bed flat: 3-5 days
3-bed house: 5-10 days
It can be disruptive, especially if the property is occupied. Some homeowners choose to temporarily move out or coordinate the rewire alongside renovation works.
Can You Rewire a House in Stages?
Yes, partial rewires or staged work are possible, especially in larger homes or listed properties. However, full rewiring in one go is often more cost-effective and easier to certify.
