Solar panels represent a significant investment, with the average UK system costing between £5,000 and £10,000. Protecting this investment through adequate insurance is essential, yet many homeowners are unclear about what cover they have, what is excluded, and how to make a claim if something goes wrong. The good news is that most home insurance policies automatically cover roof-mounted solar panels as part of buildings insurance, but there are important details to understand before you need to make a claim.

Standard home insurance typically covers solar panels against storm damage, fire, theft, and vandalism. However, accidental damage is usually an optional extra, and mechanical breakdown or wear and tear is not covered at all. Battery storage systems may require separate notification to your insurer, and failing to declare your solar installation could invalidate your entire policy. Understanding these nuances before damage occurs can make the difference between a successful claim and a rejected one.

This guide explains everything UK homeowners need to know about solar panel insurance claims: what is covered, what is excluded, how to notify your insurer, the claims process, common pitfalls that lead to rejected claims, and tips for ensuring you have adequate protection for your entire system including batteries and inverters.

How Solar Panel Insurance Works

Buildings Insurance Coverage

Roof-mounted solar panels are considered a permanent fixture of your home, which means they are automatically covered under buildings insurance rather than contents insurance. This is the same category as your roof tiles, windows, and built-in kitchen units. The key requirement is that your policy’s sum insured (rebuild value) must be high enough to include the cost of replacing your solar panels.

Insurance TypeWhat It CoversSolar Panels Included?
Buildings insuranceStructure of home and permanent fixturesYes (roof-mounted panels)
Contents insurancePossessions and removable itemsPortable/freestanding panels only
Accidental damage (add-on)Unintentional damage by householdIf purchased as extra
Home emergency coverEmergency repairsGenerally not applicable

What Standard Policies Cover

PerilCovered?Examples
Storm damageYesHigh winds, heavy rain, hail, snow damage
FireYesHouse fire, electrical fire, lightning strike
TheftYesPanels stolen from roof
VandalismYesDeliberate damage by third party
Falling treesYesTree or branch falls onto panels
SubsidenceYesGround movement damages roof and panels
Impact damageYesVehicle collision, aircraft debris
FloodUsually yesFlood water damages ground-mounted system

What Standard Policies Exclude

Exclusions are where people most often get caught out. Wear and tear, mechanical breakdown, and manufacturing defects are all warranty territory, not insurance – see our dedicated guide to solar panel warranty claims for how those routes work.

Notifying Your Insurer

Why Notification is Essential

Failing to inform your insurer about solar panel installation is one of the most common reasons claims are rejected. Most home insurance policies require you to notify them of significant changes to your property. Installing solar panels qualifies as a material change because it affects your home’s rebuild value and risk profile.

Consequence of Not NotifyingImpact
Claim rejectionInsurer can refuse to pay for solar panel damage
Policy voidanceIn serious cases, entire policy may be invalidated
UnderinsuranceRebuild value too low; proportional payout only
Premium adjustmentMay owe back-premium if discovered later

What to Tell Your Insurer

Information RequiredWhy They Need It
Total installation costAdjust rebuild value / sum insured
System capacity (kWp)Assess scale of installation
Number of panelsPart of system specification
Location (roof-mounted or ground)Different risk profiles
Battery storage includedAdditional fire risk consideration
Installer detailsMCS certification provides reassurance
MCS certificateProof of compliant installation

When to Notify

TimingRecommendation
Before installationIdeal; confirms cover in place from day one
Immediately after installationAcceptable; most insurers allow this
At policy renewalToo late if claim needed before renewal
NeverRisk of claim rejection; do not delay

Battery Storage Insurance

Special Considerations for Batteries

Battery storage systems require separate consideration from solar panels. Lithium-ion batteries carry a fire risk if incorrectly installed or faulty, and some insurers require specific notification or may charge additional premium. Failing to declare battery storage could result in claim rejection if a fire occurs. For a detailed brokers’ perspective on both the fire risk and the underinsurance problem that often accompanies battery installations, Omni Davis Insurance’s analysis of solar panels, lithium-ion batteries, fire and underinsurance is a good plain-English read.

AspectDetails
Must you notify insurer?Yes, always declare battery installation
Additional premium?Some insurers charge extra; typically £20 to £40/year
Fire risk concernsLithium-ion batteries have specific underwriting considerations
Location mattersIndoor vs outdoor installation affects risk assessment
Buildings or contents?Usually buildings if wall-mounted; may vary

Common Claim Scenarios

Storm Damage

Storm damage is the most common reason for solar panel insurance claims in the UK. High winds can dislodge panels or mounting brackets, flying debris can crack glass, and in rare cases large hail can cause damage.

Type of Storm DamageTypically Covered?Notes
Panel blown off roofYesIncludes damage to roof underneath
Cracked glass from debrisYesDocument debris and source if possible
Mounting frame damageYesUsually covered as part of system
Water ingress from stormYesIf caused by storm damage to panels/roof
Hail damageYesPanels tested to withstand normal hail
Lightning strikeYesMay damage inverter and electronics

Theft and Vandalism

Solar panel theft has increased as systems have become more valuable. Thieves may target panels themselves or the copper cabling. Vandalism claims require evidence of deliberate damage by a third party. For prevention strategies before claims become necessary, see our solar panel theft prevention guide.

ScenarioCovered?Requirements
Panels stolen from roofYesPolice report required
Copper cable theftYesPolice report; evidence of forced entry
Inverter stolenYesIf forced entry to property
Battery stolenUsually yesCheck battery is declared on policy
Panels vandalisedYesEvidence of deliberate damage
Graffiti on panelsUsually yesMay require cleaning rather than replacement

Fire Damage

Solar panel fires are relatively rare but can be serious. They may be caused by faulty installation, inverter malfunction, or DC arc faults. Fire damage to solar panels is covered, but the investigation may examine whether poor installation was a factor.

ScenarioCovered?Notes
House fire damages panelsYesPanels damaged as consequence of covered fire
Fire starts in inverterUsually yesUnless caused by lack of maintenance
Battery fireUsually yesBattery must be declared on policy
Fire from faulty installationMay be disputedInsurer may pursue installer’s insurance
DC arc fault fireUsually yesInvestigation will examine cause

Accidental Damage

Accidental damage is not covered by standard policies and requires an optional add-on. Without this cover, damage you cause yourself or damage from household activities will not be paid.

ScenarioCovered by Standard Policy?Covered with Accidental Damage Add-on?
Ball damages panelNoYes
Ladder falls onto panelsNoYes
Dropped tool during maintenanceNoYes
Window cleaner damages panelNo (your policy)Possibly; may need their liability insurance
Damage while cleaning guttersNoYes
Satellite dish installation damageNoYes (or installer’s insurance)

Why Claims Get Rejected

Common Reasons for Claim Rejection

ReasonWhy It HappensHow to Avoid
Non-disclosureSolar panels not declared to insurerNotify insurer before or immediately after installation
UnderinsuranceRebuild value too low to cover systemIncrease sum insured to include panel value
Wear and tearGradual deterioration, not sudden damageUnderstand this is warranty, not insurance matter
Mechanical breakdownInverter failure without external causeRely on manufacturer warranty instead
No accidental damage coverSelf-inflicted damage not coveredAdd accidental damage to policy
Battery not declaredBattery fire claim rejectedAlways notify insurer about battery storage
Poor maintenanceDamage resulted from neglectKeep records of any maintenance
Lack of evidenceCannot prove damage or valueDocument system; take photos after incidents

Disputes Over Replacement vs Repair

A common source of dispute is whether damaged panels should be replaced or repaired, and whether the insurer will pay for matching panels. If only one panel is damaged, the insurer may only replace that single panel, even if it does not match the others aesthetically or in specification.

IssueInsurer PositionYour Options
Single panel damagedReplace one panel onlyAccept or pay difference for matching set
Panel discontinuedReplace with equivalent specificationMay not match visually; negotiate
Repair vs replaceMay prefer cheaper repairGet independent assessment of repair viability
Roof repair neededShould include panel removal/reinstallationEnsure quote includes full scope

Insurance vs Warranty

Understanding the Difference

Many homeowners confuse insurance with warranty, leading to frustration when claims are rejected. Insurance covers sudden, accidental damage from external events. Warranty covers manufacturing defects and performance issues. There is no overlap between them.

IssueInsurance Claim?Warranty Claim?
Storm breaks panelYesNo
Panel stops working (no damage)NoYes (product warranty)
Inverter failsNo (unless external cause)Yes (manufacturer warranty)
Panel output drops over timeNoYes (performance warranty)
Mounting fails in normal weatherNoYes (workmanship warranty)
Theft of panelsYesNo
Battery capacity degradedNoYes (battery warranty)

Typical Warranty Periods

ComponentProduct WarrantyPerformance Warranty
Solar panels10 to 25 years25 years (80-90% output)
String inverter5 to 12 yearsN/A
Microinverters20 to 25 yearsN/A
Power optimisers20 to 25 yearsN/A
Battery10 to 15 years70% capacity at 10 years typical
Workmanship (installer)2 to 10 yearsN/A

Specialist Solar Insurance

When to Consider Specialist Cover

For most domestic installations, standard home insurance with proper notification is sufficient. However, specialist solar insurance may be worth considering in certain circumstances.

Warranty vs insuranceDifferent purposes; no overlap

Solar panel insurance is more straightforward than many homeowners assume. In most cases, your existing buildings insurance will cover your roof-mounted panels against the major risks of storm damage, fire, theft, and vandalism. The critical requirement is notifying your insurer about the installation and ensuring your sum insured is high enough to cover the system’s replacement cost. Battery storage requires separate notification and may incur a small additional premium, but most mainstream insurers now accept these without difficulty.

Where problems arise is usually due to misunderstanding what insurance covers. Mechanical breakdown of inverters, gradual battery degradation, and performance decline are warranty matters, not insurance claims. Accidental damage from household activities is excluded from standard policies unless you pay extra for this cover. And failing to declare your solar installation at all can result in claims being rejected on non-disclosure grounds, potentially leaving you thousands of pounds out of pocket.

The best protection is preparation: notify your insurer before installation, keep all documentation, maintain your monitoring access, and understand the difference between what insurance and warranty cover. If damage does occur, document everything thoroughly, report promptly, and ensure any repairs are carried out by qualified installers to maintain both your warranty and future insurance coverage.

Two five-minute actions protect you against most of the pitfalls in this article. First: email your insurer today to confirm your solar panels and any battery storage are declared on your policy, and ask them for the exact replacement value they’re covering. Second: check your MCS certificate, commissioning report and purchase invoice are saved somewhere you can find them in an emergency – ideally cloud storage as well as paper.

If you have a battery and your sum insured is below £5,000-£10,000 above your home’s rebuild value, you’re probably underinsured. The single most common reason solar-related claims get paid at less than full value is that the homeowner never updated the rebuild figure after installation. Fixing that costs nothing until renewal.
