Does Home Insurance Cover Power Surge Damage in Greece? What to Check Before the Next Blackout
Fridges, TVs and routers do get damaged when power returns. Here is what electrical-damage cover usually means, which questions to ask your insurer, how to document a claim, and what Outage.gr reports show about damage.

Key Facts
- Check three things in your policy: electrical-damage (short-circuit) cover, the per-item cap, and the deductible
- Magenta's published example: short-circuit cover up to 3% of the building sum insured, minimum €2,000, €200 deductible (its page, as of 20 Oct 2026)
- Magenta contents cover is listed from €18 a year with a €2,000 per-device cap (as of 20 Oct 2026)
- 617 Outage.gr reports (5.5%) flagged damage; in September and October about 1 report in 14 did
- Photograph the damage, keep invoices and serial numbers, and note the exact time of the outage
When the power comes back, it does not always come back politely. A short voltage spike can kill a fridge compressor board, a TV or a router, and the owner finds out when something fails to start. The first question is who pays. This guide covers the insurance side: what electrical-damage cover usually means, what to ask before you rely on it, and how to document a claim. We are not insurers or brokers and this is not insurance advice. Policies differ, so the wording of yours is what counts.
What our reports show about damage
When someone reports an outage on Outage.gr, they can tick a box to say that damage occurred. Since February, 617 of 11,247 reports (5.5%) have done so. The rate is not flat:
| Month (2026) | Reports | Damage flagged | Share |
|---|---|---|---|
| May | 645 | 31 | 4.8% |
| June | 859 | 40 | 4.7% |
| July | 1,829 | 101 | 5.5% |
| August | 2,783 | 78 | 2.8% |
| September | 3,281 | 236 | 7.2% |
| October (to the 20th) | 1,659 | 119 | 7.2% |
Read this carefully. It is what reporters told us, not verified losses, and we cannot say why September and October were higher. The autumn storms that hit Crete in mid-September are one possibility, but we cannot prove that from this data. What it does show is that damage is not rare: roughly one report in fourteen in the last two months mentions it.
Three layers of protection
- Prevention. A UPS handles cuts and dips, and a surge strip handles spikes. See our UPS guide and the power-cut kit guide.
- Insurance. Pays for damage your prevention did not stop, if your policy covers it.
- A claim against the network operator. In some cases DEDDIE can be responsible. We cover that process in the DEDDIE compensation guide and the claim documentation guide.
What "electrical damage" cover usually means
The words vary by insurer: short circuit, electrical damage, damage from voltage fluctuation, lightning. They are not the same thing, so do not assume.
- Short circuit or electrical damage usually covers appliances damaged by a fault in the electrical system or a power surge. Limits and exclusions differ.
- Lightning is often listed separately.
- Wear and tear and ageing are normally excluded: a ten-year-old fridge that fails may be treated as worn out.
- Contents vs building. Building cover protects the structure and fixed installations. Appliances, TVs and computers are usually contents.
A published example
Magenta's home insurance page, when we checked on 20 October 2026, described short-circuit cover up to 3% of the building sum insured with a minimum of €2,000, and a €200 deductible. For contents, it listed cover from €18 a year, with a €2,000 cap per device. These are Magenta's own published figures and may change. Read the current terms on the insurer's site before you buy.
Questions to ask any insurer
- Does the policy cover damage from a power surge from the grid, not only from faults inside my home?
- Is there a cap per item and a total cap for electrical damage?
- What is the deductible, and does it apply per claim or per item?
- Do you pay new-for-old or depreciated value?
- Which items are excluded (for example, equipment used for business, or items above a certain age)?
- What evidence do you need after an outage?
- Is damage from lightning treated the same as damage from a surge?

If something broke: how to document a claim
- Photograph the damage and the device's model and serial number label.
- Keep the invoice or proof of purchase, and the warranty.
- Write down the time of the outage and when power returned, and note whether neighbours were affected.
- Report the outage on Outage.gr: the report has a timestamp and a location, which can support your account. Use the evidence tool to keep everything together.
- Call DEDDIE's fault line, 11500, and ask for a reference number (see who to call).
- Get a technician's report saying what failed and why, if possible, before you throw anything away.
- Notify your insurer promptly, in writing, and follow their claim steps.
What not to do
- Do not repair or discard a damaged device before you have documented it.
- Do not assume your landlord's insurance covers your belongings: it usually covers only the building.
- Do not rely on insurance to replace prevention: a UPS and a surge strip are far cheaper than a deductible.
