Why Your Second Home Insurance Probably Has a Clause You've Never Read

There is a clause sitting in most second home insurance policies that owners rarely read until the moment they need it. By then, it is too late. It is called the unoccupancy clause. And for Cornwall second-home owners, it is one of the most significant financial risks hiding in plain sight.

What the Unoccupancy Clause Actually Says

Most standard home insurance policies define a property as "unoccupied" if no one has lived in it for more than 30 consecutive days. Some policies extend this to 60 days, but 30 days is the most common trigger across the UK market, confirmed by specialist insurers including Homeprotect, Everywhen, and loss assessors Claimrite.

Once that threshold is crossed, cover changes. Sometimes dramatically. Typical consequences, as set out in Homeprotect's unoccupied property policy terms, include:

• Escape of water (burst pipes, leaks) excluded or heavily restricted
• Theft and malicious damage removed from cover entirely
• Storm damage subject to additional conditions
• All claims potentially void until the property has been formally inspected within the required window

Some policies restore partial cover if a qualifying inspection took place within a specified period, usually every 30 days. Others simply suspend whole sections of the policy without exception.

The key point: this does not just apply to properties left empty all year. A Cornwall second home visited regularly, perhaps six or eight times annually, will routinely sit unoccupied for six, eight or ten weeks at a stretch. That is enough to trigger the clause, every single time.

Why Cornwall Makes This Risk Higher Than Average

Cornwall's coastal climate is not gentle to unoccupied properties. Storm systems arrive from the Atlantic with little warning. Properties in exposed positions face salt-laden winds, driving rain, and in winter, hard frosts that can split pipework overnight.

The claim that goes unnoticed for six weeks is not unusual. A slow leak beginning above a bedroom ceiling in February and discovered by accident in April can run to tens of thousands of pounds in remediation. In a significant number of those cases, the insurer declines to pay in full because no inspection had been recorded during the intervening period.

Coastal properties face particular issues with:

Condensation and damp. A property that sits cold and unventilated through a Cornish winter accumulates moisture. Mould can establish quickly in stone walls allowed to cool below the dew point consistently. This is rarely covered under insurance and is typically categorised as gradual deterioration, which falls to the owner to remedy at their own cost.

Storm damage to roofs, gutters and outbuildings. Slipped slates, blocked or detached gutters, and damaged fascia boards are common after a significant south-westerly. Left undetected, water ingress from a loose slate can travel unseen for weeks.

Frozen pipework. Properties left without minimum heating through a cold snap are vulnerable. As MoneySuperMarket notes, many second home policies include clauses requiring either a minimum temperature to be maintained or the water system to be fully drained during winter periods. If those requirements are not met at the time of a claim, cover may be invalidated entirely.

What Specialist Second Home Insurance Requires

Proper second home insurance is designed to account for the reality of intermittent occupation. But it carries its own conditions, and owners need to understand what they are signing up to.

Regular inspections are commonly mandated. Homeprotect's unoccupied property policy is explicit: the property must be entered and internally inspected at least once every 30 days, with dated photographs or utility records as evidence, and that evidence must be produced at the point of any claim. This is not a recommendation. It is a condition of cover.

Security requirements are specific. Approved locks, alarm systems, and in some cases monitored systems are frequently specified in policy schedules. As Everywhen confirms, if the security measures listed in your policy schedule are not in place and actively in use, a theft claim may be rejected regardless of the circumstances.

Maintenance obligations are real. Insurers are increasingly applying data-driven underwriting. A property showing signs of deferred maintenance, such as blocked gutters, cracked pointing or damp patches, may face reduced settlement or outright rejection on the grounds that damage resulted from neglect rather than an insured event.

Holiday letting introduces further complexity. If guests occasionally use the property, even informally, this must usually be declared. MoneySuperMarket is clear that most second home policies do not automatically cover third-party liability arising from guest stays. A separate endorsement is typically required.

The Inspection Requirement Is Not Optional

This point is worth stating clearly because it is the one most often misunderstood.

When a specialist policy states that the property must be inspected every 30 days, it means physically entered, walked through and evidenced with dated photographs or a written log. Homeprotect's policy documentation states this in terms: to keep your cover valid, your property must be entered and internally inspected at least once every 30 days. A drive-past does not qualify. A check that the windows are intact from the road does not qualify.

For an owner based in London, Bristol or the Home Counties, travelling to Cornwall every 30 days specifically to carry out an inspection is not realistic. Which creates an obvious problem: the insurance policy requires something the owner cannot reliably provide.

This is precisely where professional property management earns its value, not as a luxury, but as the practical mechanism by which the conditions of insurance are actually met.

What This Means in Practice

A documented inspection programme, carried out by a trusted local professional, does several things simultaneously.

It keeps your insurance valid. Meeting the inspection condition is the difference between a claim being paid and a claim being rejected. Second home premiums already run higher than standard policies, averaging around £233 annually compared to £194 for a main residence according to Compare the Market. A voided claim on top of that premium is a cost entirely avoidable with the right oversight in place.

It identifies issues before they become claims. Most major property damage events are preceded by warning signs that go unnoticed in an unoccupied property. A small damp stain, a slightly loose roof tile, a gutter beginning to pull away from a fascia: these are visible on inspection and fixable for a few hundred pounds. Left for two months, they become structural problems.

It creates an audit trail. In the event of a claim, a professional inspection log with photographs, dates and written observations is materially different from an owner's verbal assurance that the property was fine the last time they visited. Insurers know the difference, and claims handlers respond to evidence.

It provides proof of property condition prior to any incident. If a claim is contested on the grounds that damage resulted from gradual deterioration rather than an insured event, a documented inspection history showing the property was in good condition is the single most effective counter-argument available.

A Note on the Market in 2026

The broader insurance market is tightening its approach to second homes, particularly in coastal areas. According to the Association of British Insurers, cited by MoneySuperMarket, weather-related home insurance claims in the first quarter of 2025 alone totalled £226 million, some £80 million above the previous quarter. Insurers are responding by applying closer scrutiny to the management practices of second home owners.

Properties that can demonstrate professional oversight, including regular inspections, documented maintenance and vetted contractor access, are presenting a lower risk profile and attracting better terms as a result.

According to Compare the Market, citing the 2025 Local Authority Council Taxbase, there are approximately 268,000 properties recorded as second homes in England. Cornwall has one of the highest concentrations in the country. Owners who cannot evidence proper oversight are beginning to find specialist cover harder to obtain at competitive premiums.

Questions Worth Asking About Your Current Policy

If you own a second home in Cornwall and have not recently reviewed your insurance documents in detail, the following questions are worth addressing:

1. What is the unoccupancy threshold in your current policy, and have you exceeded it at any point in the past 12 months?
2. Does your policy require periodic inspections as a condition of cover, and if so, can you evidence that these have taken place?
3. Are the security measures listed in your policy schedule actually in place and in working order?
4. If you have ever had guests stay, whether family, friends or paying guests, is this declared and covered?
5. Is your insurer aware that the property is a second home and not your primary residence?

If any of these questions give you pause, it is worth reading the full policy document rather than the summary and, if necessary, speaking to a specialist broker rather than a comparison site.
