Home buildings insurance
In most cases, rooftop solar panels are covered as part of your home's buildings insurance — they are considered a fixture permanently attached to the structure. However, this is not universal. Some insurers exclude panels or require you to declare them; others impose a sum-insured limit per square metre that may not reflect the replacement cost of your system.
When you have solar panels installed, you should notify your insurer. Failure to disclose a material change to your property can in some cases affect claims. Most insurers do not increase premiums significantly for solar — the panels are generally considered to reduce fire risk compared to the alternatives — but you should confirm cover is in place.
Check the reinstatement value in your buildings policy. Your sum insured should cover the full replacement cost of your panels and inverter at current prices, which may be lower than the original installation cost (panel prices have fallen significantly) or higher (if you need scaffolding and specialist installers).
Contents insurance
Contents insurance is not normally relevant for permanently installed solar panels (these are a fixture and fall under buildings). However, if you have a battery storage unit inside the property (in a garage, utility room, or loft), check whether your insurer classifies it as contents or fixture — treatment varies.
Portable solar panels (camping/emergency use) are typically contents items if stored in the home, and may or may not be covered under a standard policy.
Public liability
This is an area sometimes overlooked. If a solar panel or mounting bracket falls from your roof and causes injury or damage to a third party, public liability cover under your buildings or home policy would typically respond. Most comprehensive home insurance policies include public liability as standard.
Confirm the public liability limit in your policy — £2 million is a common standard limit; some policies offer £5 million or £10 million. Given that a falling panel can cause serious injury, a higher limit is preferable if available at low cost.
Specialist solar insurance
Specialist solar panel insurance is available from a handful of UK providers. These policies are designed specifically for solar installations and may offer advantages over a standard home insurance policy, including: guaranteed replacement value (rather than sum insured), loss of generation income cover (for Feed-in Tariff or SEG recipients), and broader cover for mechanical or electrical breakdown beyond the manufacturer warranty.
For most residential homeowners with a standard installation, checking your existing home insurer is sufficient and adding specialist cover is not necessary. For larger installations, those with battery storage, or those relying on SEG income, a specialist policy may be worth comparing.
What insurance does not replace
Insurance covers unforeseen damage events — not gradual degradation, not soiling, and not normal wear. A panel that has degraded below its warranted output after 15 years is a warranty claim against the manufacturer (if in warranty) not an insurance claim. A panel cracked by hail is an insurance claim.
Manufacturer warranties and installer workmanship guarantees are the first line of protection for most issues a panel owner encounters. Insurance is the backstop for sudden, accidental, or external damage events.
