Introduction
Solar panels have become one of the most common home improvements in the UK, driven by rising energy costs, environmental concerns, and government incentives that have made installation more accessible than ever. Whether fitted to a roof, mounted on the ground in a garden, or installed alongside battery storage systems, solar panels represent a significant financial investment that most homeowners assume is automatically protected by their existing home insurance. That assumption is not always correct, and getting it wrong can leave you facing a substantial uninsured loss if something goes wrong.
Why Solar Panels Change Your Insurance Position
Fitting solar panels alters the structure, value and risk profile of your property in ways that matter to insurers. A roof carrying panels has additional weight, different wind loading characteristics, and new points of potential water ingress around mounting brackets. The panels themselves represent thousands of pounds of equipment exposed to weather, theft and accidental damage. Battery storage adds an entirely new dimension of fire risk that insurers are increasingly cautious about. None of this means cover is unavailable, but it does mean your insurer needs accurate information to price and structure your policy correctly.
Why This Differs From Standard Home Insurance
Ordinary home insurance is built around a fairly predictable set of risks: fire, flood, storm, theft and accidental damage to a conventional brick-and-tile structure. Solar panels introduce variables that standard underwriting was not originally designed around, particularly ground-mounted systems that sit outside the building footprint, leased panels that belong to a third party, and battery units with chemistry-specific fire characteristics. This is why declaration matters so much more here than for something like a new carpet or a repainted kitchen; the insurer needs to actively decide whether and how to extend cover, rather than simply absorbing the change into an existing structure.
Who This Guide Is For
This guide is written for UK homeowners who have already installed solar panels, are considering installation, or have inherited a property with panels already fitted. It covers roof-mounted and ground-mounted systems, owned and leased arrangements, and the growing number of installations that include battery storage. If you are a landlord with solar panels on a rented property, some of the same principles apply but you should also read our guide to landlord property insurance for the wider context of let property cover.
Key Terms Explained
- MCS Certification
- The Microgeneration Certification Scheme is the UK quality standard for small-scale renewable energy installations, including solar PV. MCS-certified installers must meet technical and consumer protection standards, and certification is often required for eligibility for export payment schemes.
- Feed-in Tariff (FiT)
- A now-closed government scheme that paid homeowners for electricity generated by renewable installations. Many existing solar panel owners still receive FiT payments under legacy agreements even though the scheme closed to new applicants some years ago.
- Smart Export Guarantee (SEG)
- The scheme that replaced the Feed-in Tariff, requiring larger energy suppliers to pay small-scale generators for electricity exported back to the grid, at rates set by individual suppliers rather than government.
- Rent-a-Roof Scheme
- An arrangement where a third-party company installs and owns solar panels on a homeowner's roof at no upfront cost, in exchange for keeping any FiT or export income, while the homeowner benefits from reduced electricity bills.
- Wind Loading
- The calculated force that wind exerts on a structure or fixed equipment, used by installers and structural engineers to determine appropriate mounting and fixing methods for roof-mounted panels.
- Sum Insured
- The maximum amount an insurer will pay out under a policy, which for buildings insurance should reflect the full rebuild cost of the property including any permanent fixtures such as solar panels.
- Thermal Runaway
- A dangerous chain reaction within certain battery chemistries where rising internal temperature causes further heat generation, potentially leading to fire. This is a key concern for insurers assessing battery storage risk.
What Solar Panel Insurance Actually Covers
There is no single standard answer to what is and is not covered, because practice varies significantly between insurers, and even between different policies from the same insurer. Broadly, once declared and accepted, most buildings policies will extend standard buildings perils cover to roof-mounted panels, meaning damage from fire, storm, lightning, escape of water and similar events is usually covered on the same basis as the rest of the building. Ground-mounted systems, battery storage and export income sit in much more variable territory.
| Cover Type | Roof-Mounted Panels | Ground-Mounted Panels | Battery Storage |
|---|---|---|---|
| Storm and wind damage | Usually included once declared | Often needs separate declaration | Varies by insurer |
| Fire damage | Usually included | Usually included if declared | May carry conditions |
| Theft | Often included | Frequently excluded or conditional | Often conditional on location |
| Accidental damage | Optional extra typically | Optional extra typically | Optional extra typically |
| Loss of export income | Rarely included as standard | Rarely included as standard | Rarely included as standard |
Advantages of Declaring Properly
- Claims are paid in full rather than reduced for non-disclosure
- Insurer can advise on suitable security and installation conditions
- Sum insured reflects the true rebuild value of your property
- Reduces risk of policy being voided over an undisclosed alteration
Trade-Offs to Be Aware Of
- Premium may increase, sometimes noticeably for battery storage
- Some insurers apply excess increases for panel-related claims
- Ground-mounted or unusual installations may need a specialist insurer
- Export income loss usually needs a separate optional extra
Roof-Mounted Panels in Detail
Because roof-mounted panels become physically fixed to the building, most insurers treat them as part of the structure for buildings insurance purposes once you have told them about the installation. This means they are generally covered against the same insured perils as the rest of your roof, though insurers may ask about the installation date, installer certification, and fixing method before confirming full cover.
Ground-Mounted Panels in Detail
Ground-mounted arrays are physically separate from the main building and many insurers treat them more like a garden structure, shed or outbuilding than part of the house itself. This often means a lower automatic level of cover, if any, and a need to specifically add the array with its own sum insured. Security measures such as fencing or anchoring may be a condition of cover given the higher theft exposure of a standalone installation.
Contents vs Buildings Classification
A recurring point of confusion is whether solar equipment falls under buildings or contents insurance. As a general rule, permanently fixed panels sit under buildings cover, while portable battery units or generators not fixed to the structure may fall under contents. Where the classification is unclear, ask your insurer directly and get the answer confirmed in writing, since applying to the wrong section of a claim can cause delays.
Specialist Situations
Leased or Rent-a-Roof Panels
If your panels were installed under a rent-a-roof or leasing arrangement, the panels themselves usually remain the property of the leasing company, which typically holds its own insurance covering the equipment. However, your own buildings insurer still needs to know the panels are fitted, because any damage they cause to your roof structure during an insured event remains your responsibility to address, and your lease agreement will usually require you to maintain adequate buildings insurance throughout its term.
Inherited Installations
If you buy a property with solar panels already fitted, do not assume the previous owner's insurance arrangements carry over. Request the original installation certificate, MCS documentation and any warranty paperwork as part of the conveyancing process, and declare the panels to your own insurer from the outset of your policy rather than after the fact.
Listed Buildings and Conservation Areas
Solar panels on listed buildings or in conservation areas usually require planning permission or listed building consent before installation, and fitting them without proper consent can create both legal exposure and insurance complications. If your property is listed, read our guide to listed building insurance for the wider context of specialist cover, and always confirm consent status with your local authority before any work begins.
New Build Properties
Increasingly, solar panels are fitted as standard on new-build homes rather than added later. If you have bought a new build with integrated solar, check how the panels are treated within your NHBC or equivalent structural warranty, and read our guide to new build home insurance for how this interacts with your first years of ownership.
Battery Storage Alongside Panels
Battery storage systems that store excess solar generation for later use are increasingly common, but they introduce fire risk considerations that insurers take seriously. Lithium-based batteries in particular can be subject to thermal runaway if damaged, poorly installed or of substandard quality. Insurers may ask about the battery's location within the property, its certification, and whether it is installed in a garage, utility room or habitable space, with some applying conditions or exclusions for batteries kept inside living areas.
Solar Carports and Outbuilding Installations
Panels fitted to a carport, garage roof or other outbuilding rather than the main house need to be checked against your policy's definition of the insured buildings, since some policies only automatically extend to the main dwelling and treat detached structures separately, sometimes with a lower sum insured limit.
Underinsurance Risk After Installation
Adding a significant piece of equipment like a solar array increases your property's rebuild value, and failing to increase your sum insured accordingly can leave you underinsured, which may result in a proportionally reduced payout even on an otherwise valid claim. Read our guide to underinsurance in home insurance for a fuller explanation of how this works and how to avoid it.
Properties in High Flood Risk Areas
Ground-mounted arrays positioned in gardens with flood exposure need particular attention, since flood water can damage inverters, wiring and mounting structures even if the panels themselves survive. If your property carries flood risk, read our guide to flood insurance for how this interacts with wider buildings cover.
Multiple Installations Over Time
Some homeowners add further panels, upgrade inverters, or add battery storage some years after the original installation. Each material change should be reported to your insurer separately rather than assuming an earlier declaration covers later additions, since insurers price and record risk based on what they were told at the time.
Off-Grid and Hybrid Systems
Fully or partially off-grid systems that are not connected to the national grid, sometimes used in rural or remote properties, may fall outside standard solar insurance provisions entirely and often need a specialist rural or smallholding insurer familiar with self-generation setups.
What Affects the Cost
The premium impact of solar panels is usually modest compared with the overall cost of your buildings insurance, but several factors influence how much of an increase you might see.
- Whether panels are roof-mounted or ground-mounted
- The size and value of the installation
- Presence and type of battery storage
- Installer certification and documentation available
- Security measures for ground-mounted arrays
- Your property's claims history
- Whether accidental damage cover is added as an optional extra
Claims History and No-Claims Standing
A property with a clean claims history is generally rated more favourably regardless of the specific perils involved, and insurers may take a more flexible view of solar-related risk factors where the wider policy history is strong. Conversely, a recent claim of any kind can make an insurer more cautious about additional risk elements like ground-mounted arrays or battery storage.
Excess Levels for Solar-Related Claims
Some insurers apply a specific excess for claims relating to solar equipment, separate from the standard buildings excess, particularly for accidental damage. It is worth asking specifically about this when arranging or renewing cover, since it affects what you would actually receive after a successful claim.
Bundling With Wider Home Insurance
Declaring solar panels as part of a single combined buildings and contents policy is usually more cost-effective than trying to arrange separate standalone cover for the equipment, and simplifies the claims process since there is only one insurer to deal with regardless of what caused the damage.
Choosing the Right Cover
- Gather your installation certificate, MCS documentation and any warranty paperwork.
- Contact your insurer to declare the panels, whether newly installed or previously undeclared.
- Ask specifically how roof-mounted, ground-mounted and battery elements are each treated.
- Confirm your buildings sum insured has been adjusted to reflect the added value.
- Review whether accidental damage and export income cover are worth adding as extras.
Checking the Insurer's Claims-Handling Reputation
Price should not be the only factor. Look at independent reviews and complaints data to understand how an insurer actually handles solar-related claims in practice, since a slightly cheaper policy is poor value if claims are routinely delayed or disputed.
Considering a Specialist Renewable Energy Insurer
For larger installations, unusual ground-mounted arrays, or properties combining solar with other renewable technology such as ground source heat pumps, a specialist renewable energy insurer may offer more appropriate and comprehensive cover than a standard high-street home insurer.
Your Legal Duties and Protections
As a residential policyholder, your relationship with your insurer is governed by the Consumer Insurance (Disclosure and Representations) Act 2012, which requires you to take reasonable care to answer questions honestly and accurately when applying for or renewing a policy. Installing solar panels is a material change that most insurers will ask about directly, whether at the point of installation or at your next renewal, and you should proactively disclose it rather than waiting to be asked if there is any doubt.
What Happens if You Do Not Disclose
If undeclared solar panels are damaged, stolen, or cause damage to your property, your insurer may reduce a claim payout to reflect what they would have charged had they known, apply different terms retrospectively, or in cases of deliberate or reckless non-disclosure, treat the policy as void from the outset. This is one of the most common and entirely avoidable reasons that solar-related claims are reduced or rejected.
Your Right to a Cooling-Off Period
When you take out a new home insurance policy or add solar cover as a mid-term adjustment, you typically have a 14-day cooling-off period during which you can cancel without penalty if the cover does not suit your needs, though any period of cover already provided may be charged for on a pro-rata basis.
Data Protection and Your Information
Insurers process personal and property data in line with UK data protection law, and you are entitled to know how your information is used, stored and shared, including with any third parties involved in assessing solar-related risk such as structural engineers or specialist surveyors.
Ongoing Duty to Update Your Insurer
Your disclosure duty does not end once your policy is in place. If you add further panels, upgrade your battery, or make other changes to the installation, you should update your insurer promptly rather than waiting for renewal, since a mid-term change in risk is still something they are entitled to know about.
Real-World Examples
Case Study: Storm Damage to Declared Panels
A homeowner in Yorkshire had declared their roof-mounted panels when installed two years earlier. Following a severe winter storm, several panels were torn loose and the roof beneath was damaged. Because the panels had been properly declared and installed by an MCS-certified fitter, the claim was accepted in full, covering both the panels and the resulting roof repair.
Case Study: Undeclared Ground-Mounted Array
A homeowner in Norfolk installed a ground-mounted array in their garden but did not inform their insurer, assuming it fell under general garden cover. When the array was targeted by thieves, the insurer discovered during investigation that the installation had never been declared and significantly reduced the settlement, reflecting the terms that would have applied had proper disclosure been made.
Case Study: Battery Storage Fire Incident
A homeowner with a battery storage unit installed in an integral garage experienced a fire believed to have originated in the battery system. Because the installation had been declared, was professionally certified, and the battery was sited in line with the insurer's stated conditions, the claim was accepted, though the insurer's investigation into cause took several additional weeks.
Case Study: Rent-a-Roof Dispute After a Storm
A homeowner with panels installed under a rent-a-roof scheme suffered roof damage in a storm that also affected the leased panels. Confusion arose over whether the homeowner's buildings insurer or the leasing company's equipment insurer was responsible for which element of the damage, which was eventually resolved by both insurers agreeing to handle their respective elements once the lease agreement was reviewed.
Making a Claim
- Report the damage to your insurer as soon as reasonably possible.
- Take clear photographs of the damage before any repair work begins.
- Avoid using the system if there is visible damage, given possible fire or electrical risk.
- Obtain a report or repair quote from a qualified, ideally MCS-certified, solar installer.
- Keep all correspondence, receipts and reports until the claim is fully resolved.
Working With Loss Adjusters
For larger or more complex claims, your insurer may appoint a loss adjuster to assess the damage independently. It is reasonable to also obtain your own independent report from a solar specialist, particularly if you disagree with the adjuster's assessment of cause or extent of damage.
Claims Involving Both Buildings and Equipment
Where a single incident, such as a storm, damages both the roof structure and the panels themselves, make clear in your claim that both elements are affected, since these may be assessed under slightly different parts of your policy and it helps to have both addressed within the same claim reference.
Common Mistakes to Avoid
- Assuming solar panels are automatically covered without checking
- Not declaring panels installed before you took out your current policy
- Forgetting to update your insurer after adding battery storage later
- Not increasing your buildings sum insured after installation
- Assuming leased panels mean you have no insurance responsibilities
- Not keeping installation and MCS certification documents safe
- Continuing to use a system after visible storm or impact damage
- Not checking whether ground-mounted arrays need separate declaration
- Assuming export income loss is automatically covered
- Failing to check planning consent requirements for listed properties
- Not confirming battery storage location conditions with your insurer
- Overlooking the need to reconfirm cover when moving to a new insurer
Myths vs Facts
- Myth: Solar panels always increase your home insurance significantly. In most cases the increase is modest and far smaller than the risk of being uninsured.
- Myth: Ground-mounted and roof-mounted panels are treated the same. They are frequently treated quite differently, with ground-mounted arrays more often needing separate declaration.
- Myth: Once declared, you never need to update your insurer again. Further additions or upgrades should be reported as they happen.
- Myth: Leased panels mean you have no insurance responsibility at all. You still need to inform your own insurer and maintain adequate buildings cover under most lease agreements.
- Myth: Installer insurance replaces the need for home insurance declaration. These are separate protections covering different risks and time periods.
- Myth: All battery storage systems are treated identically by insurers. Chemistry, location and certification all affect how an insurer assesses the risk.
- Myth: Feed-in Tariff income is automatically protected if panels are damaged. Most standard policies do not cover loss of export income without an added extra.
Frequently Asked Questions
Does home insurance automatically cover solar panels?
Not automatically in every case. Roof-mounted solar panels are usually treated as part of the building once fitted, so most buildings insurance policies extend to cover them, but this is not guaranteed and some insurers exclude them unless declared. Ground-mounted arrays are frequently excluded altogether unless specifically added. You should always confirm the position with your insurer rather than assume cover exists.
Do I need to tell my insurer I have solar panels?
Yes. Under the Consumer Insurance (Disclosure and Representations) Act 2012 you must take reasonable care to answer your insurer's questions honestly and accurately, and installing solar panels is a material change to your property that most insurers expect to be told about. Failing to disclose can lead to a claim being reduced or refused.
Are solar panels covered against theft?
Many standard buildings policies include theft cover for fixed panels once declared, but ground-mounted panels and detachable battery units are more vulnerable and some insurers apply specific theft conditions, security requirements or exclusions to these. Check your policy wording carefully rather than assuming blanket theft cover applies.
Does insurance cover storm damage to solar panels?
Most buildings policies that include declared solar panels will cover storm and wind damage, though insurers may apply conditions relating to installation standards, wind loading calculations and how the panels were fixed. Damage caused by poor original installation rather than the storm itself may be treated differently.
Does installing solar panels affect my premium?
Usually yes, though the effect is often modest. Insurers may adjust the rebuild sum insured and premium to reflect the added value and risk profile of the panels, and battery storage systems can have a more noticeable effect due to fire risk considerations. The increase is typically far smaller than the cost of leaving panels undeclared and uninsured.
Are solar panel installers required to have insurance?
Reputable installers should hold public liability insurance and, where relevant, professional indemnity cover, and MCS-certified installers are required to meet certain standards including guarantee-backed workmanship cover. This protects you if the installation itself causes damage, but it is separate from your own home insurance and does not replace the need to declare the panels to your insurer.
Does insurance cover loss of feed-in tariff or export income?
Standard buildings insurance does not typically cover loss of Feed-in Tariff, Smart Export Guarantee payments or other export income if panels are damaged and cannot generate electricity. Some specialist or enhanced solar policies offer this as an optional extra, so check whether business interruption or loss-of-income style cover is available if this income matters to you.
What happens if I do not declare my solar panels?
If you do not declare solar panels and they are later damaged, stolen or cause damage to your property, your insurer may reduce the claim payout, apply the terms it would have offered had it known, or in cases of deliberate or reckless non-disclosure, void the policy entirely. Undeclared alterations are one of the most common reasons claims are reduced.
Are ground-mounted solar panels treated differently to roof-mounted panels?
Yes. Ground-mounted arrays sit outside the main building footprint and many standard home insurance policies do not automatically extend cover to them, treating them more like garden structures or outbuildings. They often need to be specifically added, sometimes with separate sums insured and security conditions.
Does battery storage need separate insurance?
Battery storage units usually need to be declared alongside the panels rather than insured entirely separately, but insurers increasingly ask specific questions about battery make, model, installation location and fire safety certification given the fire risk associated with some battery chemistries. Some insurers apply conditions or exclusions for batteries stored inside habitable rooms.
Will my mortgage lender need to know about solar panels?
Most lenders expect to be informed of significant alterations to a mortgaged property, and some require consent before installation, particularly for roof-mounted systems or where panels are leased rather than owned outright. Failing to inform your lender can create complications when you come to sell or remortgage.
Are leased or rent-a-roof solar panels covered by my home insurance?
Leased panels remain the property of the leasing company, which usually holds its own insurance for the equipment, but your buildings insurer still needs to know they are fitted because any damage they cause to your roof or the panels themselves during a storm, fire or other insured event still affects your policy and your obligations under the lease.
How do I make a claim for damaged solar panels?
Report the damage to your insurer as soon as possible, take photographs before any repair work, obtain a report or quote from a qualified solar installer, and avoid using the system if there is visible damage until it has been checked, since damaged panels and wiring can present a fire or electrical risk.
Can an insurer refuse to cover a property with solar panels?
It is uncommon for an insurer to refuse cover outright purely because of solar panels, but some may decline certain non-standard installations, older systems without proper certification, or ground-mounted arrays of unusual scale, and may direct these cases to a specialist insurer instead.
Does installing solar panels invalidate a listed building's insurance?
Not automatically, but listed buildings usually require planning permission or listed building consent before panels are fitted, and installing them without the correct consent can create both legal and insurance complications. Specialist listed building insurers should always be told about solar installations in advance.
What if my neighbour's solar panels damage my property?
If a neighbour's solar panel detaches in a storm and damages your property, this would usually be pursued through your own buildings insurer in the first instance, who may then seek to recover costs from the neighbour's insurer if negligence in installation or maintenance can be shown.
How do I complain if my solar panel claim is rejected?
Raise a formal complaint with your insurer first, requesting their final response in writing. If you remain unsatisfied after eight weeks, or receive a final response you disagree with, you can refer the complaint to the Financial Ombudsman Service free of charge.
Complaints and Disputes
If you believe a solar-related claim has been handled unfairly, start by raising a formal complaint directly with your insurer and requesting their final response in writing. Most insurers aim to resolve complaints within eight weeks.
Escalating to the Financial Ombudsman Service
If you remain unsatisfied after receiving a final response, or if eight weeks pass without resolution, you can refer your complaint to the Financial Ombudsman Service free of charge. The Ombudsman can review the insurer's decision and, where appropriate, direct a fairer outcome.
Disputes Over Installation Standard
Where a dispute centres on whether the original installation met an adequate standard, evidence from an independent MCS-certified installer or structural engineer can be persuasive in supporting your position, particularly where the insurer's own assessment conflicts with the original installer's documentation.

Conclusion
Solar panels are a valuable and increasingly common addition to UK homes, but they are not something you can safely assume your existing insurance already handles correctly. The difference between roof-mounted and ground-mounted systems, the added complexity of battery storage, and the distinct treatment of leased installations all mean that proper declaration is essential rather than optional.
Taking a few straightforward steps, declaring your installation, keeping certification documents safe, confirming your sum insured reflects the added value, and checking exactly what your policy covers, will put you in a far stronger position if you ever need to make a claim. When in doubt, ask your insurer directly and get the answer in writing.
