Types of House Rewiring Project
Partial Rewire
A partial rewire can deal with specific problem areas, but the cost and practicality depend on how much of the existing installation can safely remain.
Pros
- Cheaper than a full rewire in some cases
- Can target priority areas
- Useful for localised upgrades
Cons
- Not always the best long-term answer
- Can be harder to integrate old and new wiring cleanly
Best for: Properties where only some circuits or areas need upgrading
Full House Rewire
A full rewire is the most comprehensive option and is often the right choice for older properties with outdated wiring.
Pros
- Most complete safety and upgrade route
- Supports modern electrical demands
- Can simplify future works
Cons
- Expensive and disruptive
- Often needs making good afterward
Best for: Older homes undergoing major renovation or electrical modernisation
Rewire During Renovation
Rewiring during a wider refurb can sometimes be more efficient because floors and walls may already be open for other work.
Pros
- Can reduce duplicated disruption
- More efficient during larger projects
- Often better access to routes and surfaces
Cons
- Still a major job
- Costs can rise if scope grows during renovation
Best for: Homes already undergoing major refurb or layout changes
The total cost depends mainly on the size of the property and whether the project is a full rewire, a partial rewire, or a rewire taking place alongside renovation work.
What Affects the Cost
- Property size and layout
- Whether the job is full or partial rewire
- Occupied versus empty property conditions
- Number of sockets, lights, and circuits required
- Condition of walls, ceilings, and floors for cable runs
- Need for new consumer unit and certification
Labour Cost Breakdown
Labour is typically 30–50% of the total installation cost. The complexity of the job determines how long it takes.
What Is Usually Included
- Removal or abandonment of old wiring where appropriate
- Installation of new circuits, cabling, and accessories
- Testing and electrical certification
- Consumer unit replacement where specified
- Basic first-fix and second-fix electrical labour
Extra Costs to Expect
These aren't always required, but it's worth knowing about them before you get quotes.
Running Costs & Potential Savings

Frequently Asked Questions
How much does it cost to rewire a house in the UK?
Costs vary widely by property size and scope, but a full rewire is usually a major multi-thousand-pound project.
What affects house rewire cost most?
Property size, access, occupancy, the number of circuits and accessories, and making-good requirements are usually the biggest factors.
Is it cheaper to rewire an empty house?

How long does a rewire take?
Smaller jobs may take a few days, while full rewires of larger houses often take one to three weeks.
Does rewiring include plastering?
Not always. Many electricians exclude plastering and decoration, so it is important to check this in the quote.
