Solar Panels and Home Insurance in Ireland

Every rule, definition and figure on this page was read from the Act, the regulator, the surveyors' body or an insurer's own published document on 22 August 2026, and each source is listed at the end.

The Law Changed, and Most Advice Did Not

Search this question and you will be told you have a duty to disclose anything material to the risk, and that failing to do so can void your policy. That is the old common-law position of uberrima fides. In Ireland it is gone.

Section 8 of the Consumer Insurance Contracts Act 2019 replaced it outright, and it has been in force since 1 September 2021. The section states that its duties replace "the principle of utmost good faith (uberrima fides) and any duty of disclosure of a consumer (including any duty on the consumer to volunteer information) that applied prior to the commencement of this section". It then narrows what is left to a single sentence: "The pre-contractual duty of disclosure of a consumer is confined to providing responses to questions asked by the insurer, and the consumer shall not be under any duty to volunteer any information over and above that required by such questions."

Two more parts of section 8 matter to a solar owner. The insurer must ask specific questions, in writing, and "shall not use general questions". And where a question is ambiguous, "the interpretation most favourable to the consumer shall prevail". What you do owe is set out in section 8(7)(a): a duty "to answer all questions posed by the insurer honestly and with reasonable care", measured against the average consumer.

So if your renewal declaration asks whether you have made any structural alterations, or asks specifically about solar panels or battery storage, answer it and answer it accurately. If nothing on the form goes near the subject, silence is not a breach of the Act.

Buildings or Contents? Read Your Own Definition

Irish policies do not usually name solar panels in the buildings definition. They do not have to, because the definition is written around fixtures.

Aviva's HomeCare policy booklet defines buildings as "Your home and its fixtures and fittings, interior decorations, swimming pools, outdoor spas or hot tubs which are fixed or fitted to the premises, fuel, septic and service tanks, terraces, patios, decks, paths, driveways, tennis courts, walls, fences and gates for which you are legally responsible, all within the boundary of the risk address shown in your schedule." Fixed to the roof, panels sit inside that. Allianz is more direct on its own guide: "Within your home policy, solar panels are treated as fixtures and fittings within the boundary of the premises," and it says it covers them "as a standard part of the buildings (or premises) cover".

The exclusion list is where you should slow down. The same Aviva definition carries an exclusion that catches people out: "Buildings does not include: polytunnels, wind turbines." A domestic wind turbine is a micro-generator like solar PV, and under that wording it is not buildings property at all. Do not assume one renewable technology is treated like another.

Where each part of a solar installation usually sits, based on standard Irish buildings and contents definitions

Component	Usual treatment	What to check
Roof-mounted panels and mounting rails	Buildings, as fixtures and fittings	Nothing, in most wordings. Confirm in writing.
Inverter, isolators, wiring	Buildings, as fixed installations	Whether breakdown as distinct from damage is covered. It usually is not.
Home battery	Usually buildings if hard-wired and fixed	Ask explicitly. Some insurers ask where it is sited.
Ground-mounted array	Depends on the wording; it is outside the house but inside the boundary	Ask directly. Do not infer it from the roof-mounted position.
Domestic wind turbine	Excluded from buildings in at least one major Irish wording	Read your own exclusion list before assuming cover.

Whether accidental damage is covered is a separate question from whether the panels are insured property. On the Aviva wording, accidental damage is an optional extension and its exclusions include "anything which happens gradually", "electrical or mechanical breakdown", and "wear and tear, atmospheric or weather conditions". A panel that quietly loses output over four years is a warranty conversation with your installer, not a claim.

The Sum Insured Is the Real Exposure

This is the part that costs people money, and it has nothing to do with disclosure.

Irish buildings cover is written on rebuild cost, not market value. The CCPC puts it plainly: "Insure your home for the rebuild cost, not market value," and warns that "if you underinsure, your policy may not cover the full cost of repairs or rebuilding."

The standard reference here is the Society of Chartered Surveyors Ireland guide, A Guide to Calculating House Rebuilding Costs for Insurance Purposes (2025/26), published on 4 November 2025. Read its assumptions rather than its headline rates. The figures are "a MINIMUM base cost guide"; they assume a standard specification whose heating and thermal element runs to "insulation, minimum air-tight construction, humidity wall vents, and heat pump to latest BER ratings"; and the SCSI tells you the sum insured "should be increased to allow for better-than-average kitchen fittings, built-in wardrobes, finishes and any other items not normally included in an estate-type house."

Solar PV is not in that standard specification. On the SCSI's own logic it belongs in the amount you add, the same way a high-spec kitchen or a garden office does.

What happens if you do not add it is set out in the SCSI's own worked example. Where a house is insured for €270,000 and the true reinstatement cost is €360,000, the guide says that on a partial loss "which costs €60,000 to repair, the insured party may only receive €45,000 and would have to provide the balance of €15,000". That is a 75% payout on a claim with no connection to the roof at all.

The SCSI calculator covers estate-type houses built since the 1960s. It does not cover one-off rural homes, period properties, apartments, or houses with basements or more than three storeys. If yours is one of those, the SCSI directs you to a chartered quantity surveyor for a rebuild cost estimate rather than to the calculator, which is worth knowing before you take a number off it.

What Actually Happens If You Never Mentioned It

Assume the worst case: your insurer asked a specific question, you answered it carelessly, and now you are claiming. The 2019 Act removed the all-or-nothing outcome most people fear and replaced it with proportionate remedies in section 9.

Remedies for misrepresentation under section 9, Consumer Insurance Contracts Act 2019

If the misrepresentation was	What the insurer may do
Innocent, and you met the section 8 duty	The insurer "shall be required to pay the claim made and shall not be entitled to avoid the contract on the ground that there was a misrepresentation".
Negligent, and it would have refused cover entirely	Avoid the contract and refuse claims, but it "shall return the premiums paid".
Negligent, and it would have insured on different terms	Treat the contract as if those terms applied.
Negligent, and it would have charged more	"Reduce proportionately the amount to be paid on a claim".

Section 8(6) adds a hurdle for the insurer even then: it may use those remedies "only if it establishes that non-disclosure of material information was an effective cause of the insurer entering into the relevant contract of insurance and on the terms on which it did".

Then there is the "material change" clause sitting in your policy conditions. Aviva's general conditions say you "may lose all benefit and cover under this policy" if there is "a material change in your circumstances", and asks you to "tell us immediately of any changes in respect of circumstances relating to you, other members of your household or the property insured". Its own examples are about occupancy: the home becoming unoccupied, not being lived in for 60 consecutive days, a change of use such as letting.

Section 15 of the Act tells you how that clause is to be read. Any clause referring to a material change "shall be interpreted as referring to changes that take the risk outside that which was within the reasonable contemplation of the contracting parties when the contract of insurance was concluded", and an alteration of risk clause "shall be void where it purports to apply where there is a modification only of the risk insured". Section 19(4) goes further on continuing conditions: breaching one suspends the insurer's liability for the duration of the breach, and if the breach is remedied before the loss, the insurer must still pay.

Fitting a common domestic upgrade to your own roof is a hard thing to argue was outside reasonable contemplation. None of which is a reason to stay quiet, because none of it repairs an underinsured sum.

Storm, Hail and What Owners Actually Claim For

Aviva published research on this in August 2026, based on a survey of 750 Irish homeowners carried out by 3Gem Research & Insights. It found that 18% of homeowners with solar panels or home battery systems "have experienced weather-related issues with these technologies", and that weather was the most commonly reported problem among those who had an issue at all. Aviva says it has seen an increase in customer queries about solar panels as adoption has grown.

Gillian Devereux, Senior Loss Adjuster at Aviva Insurance Ireland DAC, put the insurance point this way in the same release: "Homeowners should also let their insurer or broker know if they install these systems, as many home insurance policies provide cover for accidental damage and damage caused by insured events such as storms."

Note the framing. Storm damage is an insured event. Gradual decline is not, and Aviva's own advice is about heading it off: periodic inspection by a qualified professional, watching for corrosion, water ingress or error messages, keeping the roof and mounting hardware sound, and retaining the records. Our page on solar panel cleaning and maintenance covers the routine side of that, and how long solar panels last in Ireland covers what normal degradation looks like so you can tell it apart from damage.

Installation Paperwork Is Claims Paperwork

An insurer assessing a fire or a water-ingress claim will ask who did the work. Ireland already has a clear answer to that question, and it is not optional.

ESB Networks' micro-generation rules put the obligation on the homeowner: "It is your responsibility to ensure that the Micro-Generator is installed by a registered electrical contractor to Safe Electric standards." The inverter "must comply with IS EN50549-1 with current Irish settings", and a type test certificate confirming that has to accompany the NC6 notification form. Keep all of it.

• The signed NC6 notification and the type test certificate. See our guide to the NC6 form.
• The completion certificate from the Safe Electric registered electrical contractor.
• The installer's invoice, showing what was installed and what it cost.
• Panel, inverter and battery warranties, with serial numbers.
• Any post-works BER and grant correspondence if the job was grant-aided.

If you are still choosing an installer, the registration question is worth understanding properly first: Safe Electric and SEAI registration are two different things, and only one of them is about electrical work. Our guide to vetting a solar installer covers the rest.

What to Do, in Order

1. Tell your insurer or broker in writing. Email beats a phone call, because it produces the record. State the panel capacity in kWp, whether there is a battery, and where the battery is sited.
2. Ask three specific questions. Are the panels, inverter and battery insured under buildings? Is accidental damage included or optional? Does the premium change?
3. Get the answer in writing and keep it with the policy documents.
4. Recalculate the rebuild cost. Use the SCSI guide for an estate-type house, or a chartered quantity surveyor for anything else, and add the installed cost of the system on top of the base figure.
5. Update the sum insured at renewal, not eventually. The SCSI notes that insurers recommend reassessing cover every year for current rebuilding costs and any improvements.
6. File the paperwork from the list above somewhere you could find it the week after a fire.
