Act of God in Insurance: Challenging a Weather Claim Refusal

You clear up after heavy wind or rain, then find a roof leak, broken tiles, water staining, or damage that wasn't there before. The problem comes when your insurer says the damage was not caused by the weather at all, but by wear and tear, gradual deterioration, or poor maintenance.

That is where the phrase "act of God" causes confusion. In modern UK home insurance, the question is rarely whether something was an act of God. The real question is whether your policy covers the listed peril you are claiming for, such as storm, flood, lightning, or subsidence, and whether the evidence supports that cause.

What Is Legally Defined as an Act of God?

An act of God is usually understood as an extreme natural event outside human control, such as severe weather, lightning, flood, or another unavoidable natural occurrence. It is a broad legal phrase, but it is not how most UK consumer insurance policies usually decide weather claims.

In an act of God insurance dispute, the policy wording matters more than the label. Modern policies tend to list the specific risks they cover. These are often called listed perils. For weather claims, listed perils commonly include things like storm, flood, lightning, and subsidence, depending on the policy.

The term itself can make the phrase sound more important than it usually is. In a real claim dispute, the useful question is not usually, "Was this an act of God?," but rather "Which listed peril am I claiming under, and what does the policy wording say has to be shown?"

An act of God typically points to a natural event outside human control, while damage caused by human negligence, poor maintenance, or gradual deterioration is usually assessed under exclusions and conditions in the policy wording.

You should therefore look in:

  • The section you are claiming under: This is where the policy sets out the cover for buildings, contents, accidental damage, storm, flood, or another insured event.
  • The general exclusions: This is usually where exclusions for wear and tear, gradual deterioration, faulty workmanship, and maintenance issues sit.
  • The policy schedule: This shows the cover, sums insured, excesses, and any specific limits that apply to your policy.

Note: "Act of God" is also different from "force majeure". Force majeure is a contract clause that may cover natural events, but can also include human-made events such as war, strikes, or government action. For a home insurance claim, force majeure is usually not the central issue, but the listed peril and the exclusions.

What Standard UK Policies Typically Cover

Insurance may pay for damage caused by an event someone might casually call an act of God, but only if the policy responds to the specific peril. A storm claim, a flood claim, a lightning claim, and a subsidence claim are all different types of claims, and each depends on the policy wording and the facts.

For weather damage, most disputes start with three questions:

  1. Covered event: Does the section you are claiming under cover the type of weather event, such as storm, flood, or lightning?
  2. Policy definition: Does the event meet the policy's definition of that peril?
  3. Cause of damage: Did that event cause the damage, or is the insurer saying the damage came from wear and tear or poor maintenance?

How FOS Defines Storm Damage

Storm damage is where the dispute often sharpens. The Financial Ombudsman Service explains storm complaints by asking whether there were storm conditions, whether the damage is consistent with a storm, and whether the storm was the main cause of the damage. Their approach to storm damage complaints is practical and not specifically based on the phrase "act of God".

Wind speed is one part of that. The Financial Ombudsman Service generally treats wind speeds of at least 55 mph as storm force. The Met Office Beaufort scale describes Beaufort force 10 as a storm, with wind speeds of 55 to 63 mph. Higher categories include violent storm and hurricane force winds.

Other Factors to Consider

That does not mean wind speed is the only evidence you need. Heavy rain, snow, hail, local exposure, and the condition of the property can all matter. But if your insurer says there was no storm, postcode-level historical weather data can be useful because it gives an objective starting point.

A weather event can also cause damage that is not obvious immediately. For example, roof damage may let water in later, or a leak may only show once rain tracks through a ceiling. The relevant issue is still causation. You need evidence linking the later visible damage back to the covered weather event, rather than to long-term deterioration.

Why Insurers Refer to Storm Damage as Wear and Tear

A refusal letter that calls out wear and tear for what looked like storm damage is common in home insurance. A roof leak the insurer attributes to poor maintenance rather than to a storm is one of the standard ways this dispute arises.

The reason is simple. Home insurance usually covers sudden damage caused by an insured event. It usually does not cover gradual deterioration, ordinary ageing, or maintenance problems that build up over time. The wear and tear exclusion is often found in the general exclusions, while any maintenance obligations may appear in the general conditions or the relevant buildings section of the policy wording.

Where a claim cannot be traced clearly to one sudden event, insurers often argue gradual deterioration. However, what truly matters is whether the damage was caused by a covered event, such as a storm, or by a problem that was already developing. If the insurer relies on a wear and tear exclusion, they need a proper basis for saying the damage came from gradual deterioration rather than the weather event being claimed for.

How to Respond to Your Insurer

The practical response is usually evidence. Met Office data may help show storm conditions existed at your postcode, but weather data alone may not prove what caused the damage. An independent surveyor's or engineer's report can be more useful because it addresses the physical cause of the damage.

For example, a report can deal with questions such as:

  • Cause of damage: Whether the pattern of damage is consistent with storm damage, rather than long-term deterioration.
  • Condition of materials: Whether the roof, wall, guttering, or other damaged part showed signs of gradual ageing before the event.
  • Timing: Whether the visible damage is consistent with a sudden weather event, including damage that appeared shortly afterwards.
  • Maintenance argument: Whether the insurer's poor maintenance point is supported by the condition of the property.

Accounting for Reasonable Care

There is also a reasonable care point, but it should not be overstated. Nearly every policy expects reasonable care of the property.

To refuse a claim on that ground, your insurer must show that you realised there was a risk your claim might happen, and that you either took no steps at all to prevent it or only took steps you knew would be inadequate.

That is a higher line than simply saying the roof was old, a gutter was blocked, or maintenance could have been better. Age and condition may be relevant, but they do not automatically answer the question of what caused the insured damage.

Gathering the Evidence Needed to Support Your Claim

A weather claim is not proved by calling the event an act of God. The burden of proof starts with showing that the claim happened and what it was worth. Whatever the policy documents specify, any reasonable form of proof can help, and a bank or credit card statement can stand in for a lost receipt.

For a storm damage refusal, you are usually trying to prove two different things. First, that storm conditions existed at the relevant place and time. Second, that those conditions caused the damage claimed for.

A useful evidence pack will usually include:

  1. The refusal letter: Identify the exact reason your insurer has given. If they mention "wear and tear", "gradual deterioration", "poor maintenance", or "no storm conditions", those are the points your response needs to address.

  2. The policy wording: Read the section you are claiming under, then compare it with the general exclusions and general conditions. The relevant wording is usually found in those places.

  3. The policy schedule: Check the cover selected, the excess, and any limits that apply to buildings, contents, accidental damage, or other relevant parts of the claim.

  4. Historical weather data: Obtain meteorological data for your postcode or closest available weather station for the date of the event. Met Office data can help show wind speed, rainfall, snow, hail, or other local conditions.

  5. Photographs and videos: Keep date-stamped images of the damage, the wider property, the surrounding area, and any temporary repairs.

  6. Repair and maintenance records: In case you have these, gather all applicable invoices, inspection records, and correspondence that show the condition of the damaged part before the event.

  7. Independent report: Consider a surveyor's report or engineer's report if the insurer says the damage came from wear and tear or gradual deterioration.

Keep in mind that while the weather data is important, it may not answer the whole dispute. If the insurer accepts there was bad weather but says the roof was already deteriorating, the stronger evidence may be a report from someone suitably qualified to comment on causation.

That report should instead focus on the physical cause of the damage, explaining why the damage pattern is consistent with storm damage, why gradual deterioration is or is not a better explanation, and whether any maintenance issue actually caused the loss being claimed for.

If a loss adjuster appointed by the insurer has inspected the property, remember their role. A loss adjuster acts for the insurer, even if they are polite and professional. A loss assessor is different, because they are engaged by the policyholder.

If the insurer maintains the refusal, FCA claims handling rules may also matter because insurers are expected to handle claims promptly and fairly, and not unreasonably reject a claim.

Finally, you should stick to what you know, avoid guessing, and avoid volunteering speculation about old maintenance issues unless it is directly relevant and accurate. If you start guessing about a loose tile, old guttering, or a past minor leak, that speculation can be repeated back in the refusal letter as support for a wear and tear argument.

How SmarterClaims Can Help

SmarterClaims can help where a weather claim has been refused because the insurer says the damage was wear and tear, gradual deterioration, or poor maintenance rather than storm damage.

It can review your refusal letter and policy documents, including the section you are claiming under, the general exclusions, the general conditions, and the policy schedule. It can then help identify the arguments your insurer is relying on and structure a challenge using the weather evidence and any independent report you have gathered.

For this kind of dispute, SmarterClaims can help draft a rebuttal letter that you then review, sign, and send yourself. That letter can explain why the listed peril may apply, address the wear and tear argument, refer to the relevant Financial Ombudsman Service approach to storm complaints, and set out the evidence in a way a complaints team can work through.

Final Thoughts

"Act of God" is usually the wrong battleground in a UK weather claim. Modern policies normally work through listed perils such as storm, flood, lightning, and subsidence, then apply definitions, conditions, and exclusions.

If your insurer says the damage was wear and tear rather than storm damage, the strongest response is usually evidence. Local weather data can help show the conditions, and an independent surveyor's or engineer's report can help address causation.

At the end of the day, the dispute may still depend on the policy wording and the facts, but a clear evidence pack gives your insurer a better basis on which to reconsider their position.

Frequently Asked Questions

Do insurance companies refer to storm damage as an "act of God"?

UK insurance policies rarely use the phrase "act of God" as the main test for a claim. They usually list specific perils, such as storm, flood, lightning, and subsidence, then define what is covered in the policy wording.

If your claim has been refused, look at the section you are claiming under, the general exclusions, the general conditions, and the policy schedule. Those documents usually matter more than the broad phrase itself.

What is the difference between force majeure and an act of God?

An act of God usually means a natural event outside human control, such as extreme weather, flood, or lightning. In contrast, force majeure is a clause that may include natural events, but can also cover human-made events such as war, strikes, or government action. In a UK home insurance claim, the key issue is usually the listed peril and the policy wording.
