Installing solar panels is a significant investment, often representing £8,000 to £15,000 out of pocket or financed over several years. Protecting that investment with appropriate insurance is essential, yet many homeowners discover after installation that their standard home insurance policy doesn’t automatically cover their new solar system as well as they assumed.

This guide explains exactly what insurance coverage your solar panels need, how to check your existing policy, what to look for when adding solar coverage, and the specific risks that a good solar panel insurance policy should protect against.

Key Takeaways

  • Most standard UK home insurance policies cover solar panels as part of the building, but always verify with your insurer
  • You must declare solar panels to your home insurer as a material change in circumstances
  • Failure to declare solar panels may invalidate your home insurance policy entirely
  • Specialist solar insurance policies typically cost £70-120 per year and offer broader coverage than standard home insurance
  • Performance insurance (protecting against generation shortfall) is separate from physical damage coverage
  • Most installer warranties cover defects but NOT storm damage, theft, or accidental damage
  • Listed buildings or unusual roof types may require specialist insurance

Does Standard Home Insurance Cover Solar Panels?

The Short Answer

Usually yes, for physical damage to the panels themselves, but with important caveats. Solar panels mounted on your roof are typically considered part of the building structure and fall under your buildings insurance (not contents insurance). However, the devil is in the details, and many standard policies have exclusions or sub-limits that apply to solar panel claims.

What You Must Do First: Declare Your Panels

This is the single most important step. You must inform your home insurer that you have installed solar panels. In insurance terms, this is a material change in circumstances that affects your policy. Most insurers ask about this at renewal, but you should notify them immediately after installation, not wait until renewal.

Failure to declare solar panels means that:

  • Your insurer can refuse to pay out on any claim (not just solar-related claims) on grounds of non-disclosure
  • Your policy may be voided entirely
  • In the event of a major claim (fire, flood, storm), your insurer has grounds to argue the risk they were covering was materially different from what was declared

This isn’t a theoretical risk. There have been cases in the UK where home insurers have declined claims following undisclosed solar panel installations.

Checking Your Policy

When reviewing your home insurance policy for solar panel coverage, check for:

  • Whether “permanently attached structures” or “fixtures and fittings” are included in the buildings coverage (solar panels should qualify)
  • Any sub-limits on high-value attachments or electrical equipment
  • Whether storm damage is covered (most standard policies cover storm damage to buildings)
  • Whether theft of panels is covered (some policies exclude theft from roofs)
  • Whether electrical faults in the inverter or wiring are covered
  • Whether accidental damage to the inverter or monitoring system is covered

What Risks Do Solar Panels Face?

Storm and Weather Damage

Storm damage is the most common cause of solar panel damage claims in the UK. High winds can lift or shift panels, damage the mounting rail system, or in severe cases cause panels to fall from the roof. Most standard home insurance policies cover storm damage to buildings, and solar panels would typically fall within this coverage.

However, some policies define storm as winds above a specific threshold (often 55mph), and damage from moderate winds or sustained wet conditions may not qualify. Check your policy’s definition of storm and whether there are exclusions for gradual deterioration or weather conditions below the storm threshold.

Theft

Solar panel theft does occur, though it is relatively uncommon for rooftop installations due to the difficulty of removing panels without specialist equipment. Ground-mounted systems and panels on accessible flat roofs carry higher theft risk. Standard home insurance may or may not cover this, depending on the policy and the circumstances of the theft.

Accidental Damage

Accidental damage to solar panels (e.g. a roofer dropping tools on a panel during other works, or debris impact) may be covered if you have accidental damage endorsement on your policy. Many standard policies don’t include accidental damage as standard, and add it as an optional extra. If you haven’t paid for accidental damage cover, you likely don’t have it.

Electrical Faults and Inverter Failure

Inverter failure is the most common technical issue with solar systems, typically occurring after 10-15 years of operation. Warranty coverage from the manufacturer (usually 5-10 years on inverters) handles failures within the warranty period. After warranty expiry, the cost of inverter replacement (£500-£2,000 depending on type and size) comes from your pocket unless you have coverage that specifically includes electrical equipment breakdown.

Standard home insurance doesn’t typically cover electrical breakdown of equipment. Specialist solar insurance or a home emergency cover policy that includes electrical systems can fill this gap.

Fire Caused by Electrical Fault

Fires originating from solar panel electrical faults (typically at the DC junction box, inverter, or cable connections) are covered by standard home insurance as fire damage. This is perhaps the most serious risk, and standard coverage is generally adequate here.

Specialist Solar Panel Insurance

What Specialist Policies Cover

Specialist solar panel insurance policies (offered by providers including Ageas, Footprint Insurance, and several others) typically include:

  • Physical damage to panels, inverter, mounting system, and cabling
  • Storm and weather damage without a minimum wind speed threshold
  • Theft of panels and equipment
  • Accidental damage
  • Electrical breakdown coverage for inverters
  • Loss of earnings from generation shortfall caused by an insured event
  • Public liability (if a falling panel damages a neighbour’s property or injures a person)

Cost of Specialist Solar Insurance

Specialist solar panel insurance typically costs £70-120 per year for a standard residential system (4-6kWp). This is modest compared to the £8,000-£15,000 asset value being protected. For larger systems or properties in high-risk locations (coastal exposure, elevated sites), premiums may be higher.

Is Specialist Solar Insurance Worth It?

For most homeowners, adding a solar endorsement to their existing home insurance policy (rather than taking out a separate specialist policy) is the most cost-effective approach. This typically costs £25-50 per year added to the home insurance premium and provides coverage for the main physical risks.

A standalone specialist policy is worth considering if:

  • Your home insurer won’t cover solar panels or charges an excessive premium
  • Your system is large (8kWp+) and represents a significant replacement cost
  • You want generation loss coverage (protection against lost earnings when the system isn’t producing due to an insured event)
  • You have a ground-mounted system with higher theft risk

Performance Insurance

What It Is

Performance insurance (sometimes called generation warranty insurance) protects against underperformance of your solar system relative to the predicted generation level in your installation contract. If your system generates substantially less than predicted (typically more than 10-15% below the estimate), performance insurance pays compensation for the lost generation value.

Is It Worth Buying?

Performance insurance is niche and typically only offered by a handful of specialists. In most cases, underperformance is caused by issues that fall under the installer’s MCS warranty obligations (defective equipment) or are due to weather variation (not insurable). For most homeowners, performance insurance is not a priority purchase. Focus first on physical damage coverage.

Case Study: A Storm Damage Claim

Background

A homeowner in the South West had a 4kWp solar system installed in 2021. During Storm Isha in January 2024, sustained winds of 70mph partially lifted three panels from their mounting rails. Two panels cracked on impact with the roof surface; the third was displaced but undamaged.

Project Overview

The homeowner called their home insurer the following day and discovered they had not formally declared the solar panels at the time of installation. The insurer initially raised the non-disclosure as an issue.

Implementation

After reviewing the policy documents, the insurer agreed that the panels constituted a permanent fixture of the building and fell within the buildings insurance coverage even without a specific declaration, as the policy did not explicitly exclude solar panels. However, the insurer requested a surveyor’s report before settling the claim. This added three weeks to the settlement process.

Results

The claim was settled for £2,400 (two replacement panels, reinstallation labour, and inspection of mounting rails). The homeowner updated their policy to formally declare the solar installation at the next renewal and paid an additional £35 per year in premium. The experience highlighted the importance of proactive declaration rather than relying on the insurer to identify coverage in an emergency.

Expert Insights From Our Solar Panel Installers

“Every installation we complete, we remind customers to contact their home insurer within 30 days. It’s part of our handover checklist. Most insurers these days are familiar with solar panels and will simply note the installation on the policy with a small premium adjustment. The problems arise when customers either forget to declare or assume the panels are covered without checking. After a major storm when they’re on the phone to the insurer, is not the time to discover there’s a declaration issue. Five minutes after installation, call your insurer. That’s all it takes to make sure you’re properly covered.”

Frequently Asked Questions

Do solar panels affect my home insurance premium?

Usually yes, but the increase is modest. Most UK home insurers charge an additional £20-50 per year to extend buildings insurance coverage to include solar panels. This reflects the higher rebuild/replacement cost of the property and the marginal additional risk. Some insurers don’t charge a premium increase at all for standard residential solar installations.

What happens if I don’t declare my solar panels to my insurer?

Failing to declare solar panels is a material non-disclosure and could invalidate your home insurance policy. In the event of a claim (even one unrelated to solar panels), your insurer could refuse to pay out on grounds that the risk they were covering was different from what was disclosed. Always inform your insurer when you install solar panels, or at the very latest at your next renewal.

Does home insurance cover solar panel theft?

This varies by policy. Some standard home insurance policies cover theft of permanently attached structures (which solar panels would qualify as), while others specifically exclude theft from roofs or don’t address it. Check your policy wording specifically. If theft of panels is a concern (particularly for ground-mounted systems or accessible flat roofs), specialist solar insurance or an explicit endorsement from your home insurer is advisable.

Is inverter failure covered by home insurance?

Standard home insurance does not typically cover electrical equipment breakdown, which is how inverter failure would be classified. Manufacturer warranties cover inverter failure within the warranty period (typically 5-12 years depending on brand). After warranty expiry, you need either home emergency cover that includes electrical systems, or a specialist solar policy that includes electrical breakdown coverage, to protect against inverter replacement costs.

What is generation loss insurance for solar panels?

Generation loss insurance (also called performance insurance) pays compensation if your solar system generates substantially less electricity than predicted due to an insured event (damage, equipment failure covered by the policy). It’s separate from physical damage coverage and relatively niche. Most residential solar owners don’t need this as standard MCS warranties and physical damage coverage address the most likely causes of underperformance.

Do I need separate insurance for a solar battery?

Your battery storage system should also be declared to your home insurer alongside the solar panels. In most cases, the battery is covered as part of the buildings insurance (for a fixed, wall-mounted battery) in the same way as the panels. Confirm this with your insurer explicitly, as battery storage is relatively new and not all policy wording specifically addresses it. The replacement cost of a 10kWh battery (£4,000-£7,000) makes this worth verifying.

Are solar panels on a listed building insured differently?

Listed buildings generally require specialist listed building insurance rather than standard home insurance, due to the higher reconstruction costs and use of specialist materials. Any solar installation on a listed building (which requires listed building consent and typically involves sympathetic design choices) should be covered under the specialist policy. Confirm the specific terms with your listed building insurer before installation.

Will solar panels affect the value of my home for insurance purposes?

Solar panels increase the rebuild value of your home (the amount it would cost to reconstruct the property from scratch), which is the basis for buildings insurance. You should inform your insurer of the solar installation value so they can adjust your buildings sum insured accordingly. Underinsurance (where sum insured is less than actual rebuild cost) can result in reduced claim payments under a proportional basis clause in your policy.

Summing Up

Solar panel insurance in the UK is largely straightforward if you take the right steps from the start. Declare your panels to your home insurer immediately after installation. Verify that your policy covers storm damage, theft, and accidental damage to the panels. Consider whether specialist solar insurance is worthwhile for your situation (particularly for larger systems or ground-mounted arrays).

The most common mistake is assuming coverage without checking. Five minutes on the phone to your insurer after installation costs nothing and ensures you’re fully protected. An uninsured panel replacement following storm damage can cost £200-£400 per panel, plus labour, that could have been covered for a few pounds per month in additional premium.

With proper insurance in place, your solar investment is well-protected. You’re free to focus on what matters: the decades of reduced electricity bills, Smart Export Guarantee income, and lower carbon footprint that a well-maintained system delivers. Getting your insurance right from day one means you’re protected and able to focus on enjoying the savings and environmental benefits your solar system generates.
