If you’re considering upgrading your home’s electrics, you may be asking:
“Is rewiring covered by home insurance?”
It’s an important question — especially when a full house rewire is a significant investment.
The answer isn’t always straightforward. In most cases, home insurance won’t pay for a rewire simply because your wiring is old, but there are situations where your insurance policy may cover damage caused by electrical faults.
In this guide, we’ll explain exactly what is and isn’t usually covered, how insurers view older electrical systems, and what Ayrshire homeowners should know before making a claim.
Does Home Insurance Pay for a House Rewire?
In most cases, no.
Home insurance is designed to cover unexpected damage, not wear and tear or routine maintenance.
If your wiring has simply reached the end of its lifespan, replacing it is considered the homeowner’s responsibility.
This is no different to replacing:
- An old boiler
- Worn roof tiles
- Rotten windows
- Ageing plumbing
A rewire is viewed as maintenance rather than an insured event.
When Could Home Insurance Cover Electrical Damage?
There are situations where your insurer may contribute towards repairs.
For example, if your electrical system is damaged by:
- Fire
- Flooding
- Storm damage
- Lightning strikes
- Escape of water affecting electrics
- Criminal damage
…your insurance may cover repairing the damaged electrical installation.
However, if an inspection shows the wiring was already unsafe or poorly maintained before the incident, insurers could reduce or reject the claim.
Every policy is different, so always check your own policy wording.
Can Old Wiring Affect My Home Insurance?
Yes.
Many insurers ask questions about your home’s electrics, particularly if:
- The property is older
- You’re buying a period home
- The house hasn’t been rewired for several decades
Some insurers may request an Electrical Installation Condition Report (EICR) before offering cover or renewing a policy.
If the inspection identifies dangerous defects, they may require these to be repaired before continuing cover.
Will My Insurance Increase If My House Needs Rewiring?
Potentially.
An outdated electrical installation represents a greater risk of:
- Electrical fires
- Circuit failures
- Damage to appliances
Some insurers may:
- Increase premiums
- Apply exclusions
- Request electrical improvements
- Ask for evidence of recent testing
Keeping your electrical installation up to date helps demonstrate that your home is properly maintained.
Should I Tell My Insurance Company After a Rewire?
Absolutely.
Once your rewire has been completed, you should let your insurer know.
A professional rewire provides evidence that your home now benefits from:
- Modern RCBO protection
- Surge protection
- New circuits
- Updated bonding
- Smoke and heat alarms
- Certification to current BS7671 Wiring Regulations
While it doesn’t always reduce premiums immediately, it demonstrates that the property has been professionally upgraded and maintained.
How Do I Know If My Home Needs Rewiring?
You should consider having your electrics inspected if your home has:
- An old fuse board with rewireable fuses
- No RCD or RCBO protection
- Wiring over 30 years old
- Flickering lights
- Frequently tripping circuits
- Discoloured sockets or switches
- Missing bonding to gas or water
Many homeowners only discover these issues after moving house or beginning a renovation.

Frequently Asked Questions
Is rewiring covered by buildings insurance?
Usually not. Buildings insurance generally covers sudden damage rather than replacing old electrical wiring that has reached the end of its life.
Will an insurance company require my house to be rewired?
Not normally, but they may request an Electrical Installation Condition Report (EICR) if the property is older or if there are concerns about the electrical installation.
Can I claim for faulty wiring on my insurance?
If faulty wiring causes insured damage, such as a fire, your policy may respond. However, insurers may refuse a claim if poor maintenance or ageing wiring contributed to the incident.
How often should a house be rewired?
There’s no fixed timescale, but many homes benefit from inspection after 25–30 years. Whether a rewire is needed depends on the condition of the installation rather than its age alone.
