How long does a full house rewire take?

A typical 3-bedroom house takes 5-10 days to rewire, depending on size and complexity. I work efficiently to minimise disruption, and you can usually remain in the property during the work with some planning.

Do I need to move out during rewiring?

Not necessarily. Many homeowners stay during rewiring. I work room by room and can maintain power to essential areas. For major works, some homeowners prefer to stay elsewhere for convenience.

Will rewiring damage my walls?

Some chasing in walls is necessary to run new cables. I minimise this where possible by using existing routes. I make good all chases with filler, but you'll need to arrange final decoration.

How often should a house be rewired?

Electrical installations typically last 25-30 years. If your home hasn't been rewired since before 1990, has old rubber or fabric cables, outdated fuse boxes, or lacks earth connections, it likely needs rewiring.

Can I claim rewiring costs on insurance?

Standard rewiring isn't usually covered as it's considered maintenance. If rewiring is needed due to an insured event (fire or flood), it may be covered. Check your policy or speak to your insurer.

What affects rewiring costs?

Property size & complexity – larger properties need more cable, circuits and time. Period properties with solid walls cost more than modern cavity-wall ones.
Accessibility – easy access to joists and wall cavities reduces labour time. Difficult access (converted lofts, limited underfloor space) increases costs.
Number of circuits & sockets – more sockets, light fittings and dedicated circuits (cookers, showers, underfloor heating) increase material and labour costs.
Additional work – consumer unit upgrades, earth bonding, outdoor lighting, data cabling, smart home, or listed building requirements add complexity.

Signs your home needs rewiring

Warning signs to watch for

•Wiring installed before 1990 (over 30 years old)
•Old rubber or fabric-covered cables visible
•Rewireable fuse box (no trip switches)
•Frequent tripping of circuits or blown fuses
•Scorch marks around sockets or switches
•Lack of earth connections on sockets

How to save money on rewiring

Get multiple quotes – compare at least 3 from NICEIC registered electricians. Ensure quotes are like-for-like and include testing, certification, and making good.
Time it with other work – most cost-effective when done alongside renovations or extensions. Walls already open, no need to redecorate twice.
Do your own decoration – electricians make good with filler. Final decoration (painting, wallpapering) usually isn't included.
Consider partial rewires – if budget is tight, prioritise critical circuits first (consumer unit, kitchen, bathroom) and rewire other rooms later.

Why use an NICEIC approved electrician?

Rewiring is notifiable work under Part P of Building Regulations. Using an NICEIC registered electrician ensures:

Work completed to BS 7671 (18th Edition) wiring regulations
Proper certification for Building Control compliance
Work covered by insurance and backed by NICEIC guarantees
No need for separate Building Control notification (saving £300-£500)
