If you’ve installed solar panels, or plan to, your building insurance may already cover them as part of the property. However, policy definitions, exclusions and notification requirements vary. Check with your insurer before work begins, confirm how the panels and any battery will be insured, and keep written confirmation.
Most UK buildings insurance treats solar panels as a permanent fixture of the property, much like a roof or a boiler. That means they’re generally included in a standard buildings policy rather than requiring a separate insurance product.
Standard cover typically extends to:
Accidental damage is often optional, while wear and tear and equipment faults are generally excluded. Ground-mounted or freestanding arrays may be treated differently from roof-mounted panels; ask your insurer whether they are covered and whether any special limits apply.
This is a useful starting point, but it isn’t a substitute for checking your own policy wording. Insurance products vary between providers, and some insurers are more explicit than others about how they treat renewable energy equipment. Reading the small print, or simply asking your insurer directly, is the only way to know exactly where you stand, rather than relying on assumptions about what “should” be covered.
Tell your insurer about a planned permanent solar installation and ask whether your policy requires notification before work starts or once it is complete. No universal legal rule requires you to disclose every mid-policy home improvement immediately; the obligation depends on the policy terms and the insurer’s questions.
Failure to provide information required by your policy can affect cover, but it does not automatically invalidate the entire policy. For consumer policies, the Consumer Insurance (Disclosure and Representations) Act 2012 governs qualifying misrepresentations made when taking out, renewing or varying cover. The insurer’s remedy depends on the circumstances and what it would have done with accurate information.
Ask whether the installation changes your buildings sum insured or any policy limits. Some policies use a blanket buildings sum insured, so don’t assume an automatic increase in the rebuild figure. Keep the replacement cost of the panels and battery available for the discussion.
Your installer will normally provide technical documents, but you should check your own insurance requirements directly. Contacting the insurer before installation is a sensible precaution and helps avoid surprises about exclusions, installation works or notification deadlines.
Depending on the policy, insured events may include:
What’s typically excluded:
Insurance generally covers insured events such as storm or fire damage. In contrast, manufacturer warranties and installer workmanship guarantees cover eligible equipment or installation faults. A warranty may not cover every performance problem, so check its conditions.
If generation drops unexpectedly, first check monitoring data and speak to the installer or manufacturer. If the reduction follows a storm, fire or another insured event, notify the insurer too. The cause of the problem determines which protection may apply.
If you add a battery, tell the insurer its location, type, capacity and approximate replacement cost. Whether it falls under buildings, contents or a separate equipment provision depends on the policy wording and how it is installed.
Don’t assume an indoor battery is automatically contents or an external battery is automatically buildings. Ask the insurer to confirm its classification, cover limits and any installation or fire-safety conditions in writing.
A garage-mounted or external-wall battery can raise specific questions about siting and cover. Confirm those requirements before installation rather than relying on generalisations about how insurers classify batteries.
Before installation, ask your insurer whether you need to notify them or obtain approval, and whether the planned works affect cover.
Provide the requested details, such as panel capacity, installation location, battery details, installer information, and estimated replacement cost. Supply an MCS certificate if issued and requested by the insurer.
Provide full system details: number of panels, kW capacity, installer name, MCS certificate number and total system value.
Ask for written confirmation that your cover has been updated, and note any change to your premium.
Keep your MCS certificate and installation paperwork on file in case you ever need to make a claim.
There is no reliable universal premium increase for adding solar panels. Some insurers may leave the price unchanged; others may adjust the premium, limits or terms after assessing the installation and insured value.
If your insurer imposes an exclusion or premium increase you consider unreasonable, compare alternative policies and obtain written confirmation of how solar equipment is treated.
At renewal, check that the recorded property details are accurate and that the policy still covers the system. This is particularly important if you’ve added battery storage or changed the installation.
Also review your policy at renewal rather than letting it auto-renew unchecked, especially in the first year or two after installation. Comparison sites don’t always capture the nuances of solar and battery cover accurately, so a quick call to a broker or insurer who explicitly asks about renewable energy equipment can be more reliable than a generic online quote.
If you omit information the insurer requires, it could affect your claim or your cover. However, an undisclosed installation does not automatically entitle the insurer to refuse an unrelated claim. The insurer must have a contractual or legal basis for its response, and consumer misrepresentation remedies are proportionate to the circumstances.
For information given when taking out, renewing or varying a consumer policy, the key law is the Consumer Insurance (Disclosure and Representations) Act 2012, not the commercial duty of ‘fair presentation’. If a dispute arises, the Financial Ombudsman Service can consider whether the insurer acted fairly and lawfully.
Ask your installer for a full specification, electrical and commissioning paperwork, relevant solar panel warranties and any MCS certificate issued for the installation. The Solar Co should confirm the precise documents it supplies before publication.
An MCS-certified installer can help demonstrate that an installation meets relevant standards, and MCS documentation may help with export arrangements. However, it is not accurate to claim that many insurers universally require MCS certification without evidence from those insurers.
Usually not for a standard roof-mounted domestic system, but you must check the individual policy. Confirm whether the panels are treated as buildings, what insured events apply and whether you need to notify the insurer.
Theft may be covered under buildings insurance, subject to the policy’s terms and exclusions. Don’t assume that failing to notify the insurer automatically defeats the claim; the answer depends on the policy and the facts.
Contact your insurer promptly, give the installation details and ask for written confirmation of cover. Failure to disclose something required by the policy can have consequences. Still, it does not automatically void every claim or the entire policy.
A manufacturing defect or gradual underperformance is generally a warranty or installer matter rather than an insured event. If the fault follows storm, fire or other insured damage, the policy may respond. Check both your warranty and insurance terms.
It can. Tell your insurer about the battery, where it is installed and its replacement value. Ask how the policy classifies it and whether any conditions, limits or exclusions apply.
Many buildings policies cover fixed, roof-mounted solar panels against insured events such as storms, fire, and theft, but coverage varies by policy. Confirm your insurer’s position before installation, including notification requirements and how they treat any battery.
If you’re planning solar, ask The Solar Co what installation and warranty documents it supplies, and share the relevant details with your insurer. The insurer—not the installer—can confirm what your policy covers.
