House Rewiring Cost (2026 Price Guide)
House rewiring costs in the UK typically range from £2,500 to £6,000+, depending on the size of the property, the age of the wiring, and how accessible the electrical system is. Smaller properties may only require partial rewiring, while older or larger homes often need a full rewire to meet modern safety standards.
This guide explains average house rewiring costs, what affects pricing, how rewiring compares to repair work, and when a full rewire is necessary.
Average House Rewiring Cost
| Property Type | Typical Rewiring Work | Average Cost |
|---|---|---|
| 1-bedroom flat | Partial or full rewire | £2,500–£3,500 |
| 2-bedroom house | Full rewire | £3,000–£4,500 |
| 3-bedroom house | Full rewire | £3,500–£5,500 |
| 4+ bedroom house | Full rewire | £4,500–£6,000+ |
| Partial house rewire | Selected circuits only | £1,500–£3,000 |
Rewiring costs increase when access is difficult or when additional electrical upgrades are required.

What Is Included in a House Rewire?
A full house rewire typically includes:
- Removing old or unsafe wiring
- Installing new electrical cables
- Replacing sockets and switches
- Upgrading the consumer unit (fuse box)
- Testing and certification
Walls, ceilings, and floors may need to be opened during the process, which adds to labour time and cost.
What Affects House Rewiring Costs?
Size of the Property
Larger homes require more materials and labour, increasing overall costs.
Age of the Wiring
Older wiring systems often need complete replacement rather than partial upgrades.
Accessibility
Homes with solid walls, finished floors, or limited access require more invasive work.
Number of Electrical Points
More sockets, lighting points, and appliances increase rewiring costs.
Occupied vs Empty Property
Rewiring an empty property is usually cheaper and faster than rewiring an occupied home.
House Rewiring vs Faulty Wiring Repair
In some cases, repairing faulty wiring may be sufficient. In others, rewiring is the safer long-term solution.
Rewiring Is Usually Recommended When:
- Wiring is outdated or unsafe
- Faults occur repeatedly
- Multiple circuits are affected
- The property has not been rewired in 25–30 years
For smaller or isolated issues, repair work may be possible. See our faulty wiring repair cost guide for a breakdown of repair vs replacement scenarios.
Can You Live in a House During Rewiring?
In many cases, yes — but it can be disruptive.
Expect:
- Power outages
- Lifted floorboards
- Opened walls and ceilings
- Limited access to rooms
Some homeowners choose to move out temporarily to speed up the process and reduce inconvenience.
How Long Does a House Rewire Take?
- 1-bedroom flat: 3–5 days
- 2–3 bedroom house: 5–10 days
- Large homes: 10–14+ days
Timelines vary based on access and complexity.
Does House Rewiring Add Value?
Yes. Rewiring:
- Improves safety
- Meets modern regulations
- Reduces fire risk
- Makes the property more attractive to buyers
While rewiring is a significant expense, it is often viewed as a long-term investment.
Does Home Insurance Cover House Rewiring?
Home insurance does not usually cover rewiring due to:
- Wear and tear
- Outdated electrical systems
However, damage caused by electrical faults (such as fires) may be covered under specific circumstances.
How to Reduce House Rewiring Costs
- Rewire during major renovations
- Combine rewiring with other work
- Reduce the number of electrical points
- Rewire before moving into a property
Planning ahead can significantly reduce costs.
