Does Home Insurance Cover Rewiring? When Insurers Pay (and When They Don't)

A full house rewire isn't cheap. Quotes run into the thousands, and the work itself is disruptive. So it's fair to ask whether your home insurance will cover any of it before you commit. The answer depends on why the rewire is needed and what caused it, with a few exceptions worth knowing about.

Does home insurance cover rewiring?

In most cases, no. Standard home insurance won't pay for a rewire just because your wiring is old, outdated, or no longer up to current regulations. Buildings cover usually does pay when an insured event - like a house fire, lightning strike, or burst pipe - damages your existing wiring. The cause is what matters.

Insurers split electrical problems into two buckets. One holds sudden, unexpected events covered by your policy. The other holds gradual deterioration, age, and faults that have built up over years. Rewiring tends to fall in the second bucket, which is why most claims are turned down. Wiring being "dangerous" isn't enough on its own. There has to be a covered event behind the damage.

When home insurance will pay for a rewire

Buildings insurance is built around damage from insured events, also called insured perils. Most policies list which events are covered. If one of these damages your wiring beyond repair, a partial or full rewire can be claimed as part of the reinstatement work.

Common insured events that can trigger a rewire claim include:

• Fire damage to your home, including kitchen fires and chimney fires

• A lightning strike that surges through your circuits and damages cabling

• Escape of water from a burst pipe, leaking tank, or failed appliance

• Flooding from a storm or external water source

• Smoke damage that contaminates wiring and fittings

• Impact damage from a vehicle, falling tree, or structural collapse

In each of these cases, the insurer will usually appoint a qualified electrician to assess the damage and decide what needs replacing. If the damage is widespread, a full rewire may be the only safe option. In our experience, a flooded kitchen or a small loft fire can end up needing far more electrical work than the homeowner expects once the walls come down.

When home insurance won't pay for a rewire

Standard cover excludes anything that builds up over time or comes down to maintenance. Rewires for safety or to bring an old house up to modern standards almost always fall outside the policy.

Typical exclusions include:

• Wear and tear from age

• Old wiring (cloth, rubber, lead-sheathed) that's reached the end of its life

• Pre-existing faults the policyholder knew about

• DIY work carried out without certification

• Upgrades for convenience, like adding sockets or installing a smart home system

• Faulty original installation work

• Issues flagged on a previous inspection and left unresolved

If the wiring causes a fire and that fire damages the rest of the property, your buildings cover will usually pay for the fire damage. The underlying wiring problem still won't be funded as an upgrade. The dividing line sits between the consequence of an event and the cause.

Buildings cover, contents cover, and home emergency: what each one does

Three types of cover come into play with electrical work, and they aren't interchangeable.

Buildings insurance

Covers the structure of your home, including fixed wiring embedded in walls, sockets, switches, and the consumer unit. If an insured event damages any of that, buildings cover funds the repairs.

Contents insurance

Covers the things inside your home: appliances, furniture, personal items. If a power surge from a lightning strike fries your TV, contents cover may pay out. It won't pay to rewire the house.

Home emergency cover

A separate add-on or standalone product. It pays for urgent call-outs and short-term repairs to keep the house safe and liveable. If you lose power to a circuit and can't reset it at the consumer unit, home emergency cover can send an electrician out. It won't pay for a full rewire, but it can stabilise things while you arrange longer-term work.

What about accidental damage cover?

Accidental damage is usually an optional add-on rather than standard. It covers one-off, unexpected events caused by you or someone in the household. The classic example is drilling into a wall and hitting a cable. If you have accidental damage cover, that repair is normally paid for. Whether the rewiring of the wider circuit is covered depends on what the electrician finds and how the insurer interprets the policy. Read the wording carefully before assuming anything.

Does an EICR help your insurance claim?

Yes. An Electrical Installation Condition Report, or EICR, is the formal inspection record of your home's wiring. It logs faults, gives them a code (C1, C2, C3, or FI), and shows the date of the assessment.

If you make a claim after an insured event, having a recent EICR on file shows that:

• Your wiring was in a known condition before the incident

• You weren't ignoring safety issues that had been flagged

• The damage is attributable to the event, not to existing faults

Electrical Safety First recommends a fixed wiring inspection at least every ten years for owner-occupied homes, and every five years for rented properties. Keeping the report and any remedial invoices makes the claims process a lot smoother. As electricians in Wolverhampton carrying out EICRs across the West Midlands, in our experience the paperwork is often what tips a borderline claim one way or the other.

How to claim on your home insurance for a rewire

If you think an insured event has damaged your wiring, the order you do things matters. Insurers expect you to limit further damage, keep evidence, and use qualified people.

1. Make the area safe. Isolate the affected circuit at the consumer unit. Don't attempt any electrical work yourself.

2. Photograph everything. Take wide shots and close-ups of the damage, the source of the incident, and the surrounding area.

3. Contact your insurer promptly. Most policies require you to report the incident within a set window. Delays can affect cover.

4. Get a qualified electrician to inspect. Use someone NICEIC-registered or signed up to another Competent Person Scheme. A written report carries weight.

5. Keep all invoices and certificates. Receipts for emergency callouts, parts, and any temporary repairs should be filed away.

6. Don't authorise major work without insurer sign-off. Insurers may want to send their own assessor. Going ahead without approval can void the claim.

Signs your home might need a rewire (insurance or not)

Some warning signs are obvious. Others only show up during an inspection. If a few of these apply, it's worth booking an EICR even if you aren't planning to claim anything.

• A fuse box with old-style rewireable fuses rather than RCDs and MCBs

• Cloth, rubber, or lead-sheathed cables visible in the loft or under the floor

• Sockets that feel warm to the touch or are scorched around the edges

• Lights that flicker or dim when an appliance switches on

• Circuit breakers that trip often without an obvious cause

• A burning smell coming from sockets, switches, or the consumer unit

• Two-core lighting circuits with no earth (common in pre-1960s homes)

• An EICR with C1 or C2 codes that haven't been addressed

Not all of these mean a full rewire is needed. Some can be sorted circuit-by-circuit. A proper inspection will tell you what's urgent and what can wait.

What if your insurance won't cover the rewire?

This is the most common situation, and it's worth being realistic about it. A standard policy is unlikely to pay for rewiring a sound but ageing system. That doesn't mean nothing can be done.

Most rewires can be staged. We often handle the highest-risk areas first - the kitchen, the bathroom, the consumer unit - then book the rest of the property in over time. Spreading the work out spreads the cost, and it keeps the most dangerous parts of the system at modern standards while you save for the rest.

A clear, written quote from a NICEIC-registered electrician is the starting point. We provide one for every job so homeowners know exactly what they're committing to before any work begins.
