Most landlords assume their insurance is a settled part of the compliance picture — a policy is in place, the premium gets paid, job done. Insurance is different from every other topic in this newsletter because the failure mode isn't a fine or a court notice. It's discovering, at the exact moment you need to claim, that the policy you've been paying for doesn't actually cover the situation you're in.

This edition covers the void period trap, why HMOs routinely fall outside standard cover, the difference between rent guarantee and loss of rent — two products landlords regularly confuse — and the practical checklist for making sure your policy actually matches what you're letting.

This is worth stating plainly because it still catches people out. Standard home insurance is generally designed for owner-occupied properties and will not cover rented properties you don't live in. Using a standard home policy for a let property invalidates cover from day one.

Some home policies might offer limited cover for a property occasionally rented out, but this is rare and usually insufficient. If you've ever let a property that started as your own home — moved out, kept the mortgage, decided to rent it rather than sell — and never actually switched the insurance, you may be sitting on a policy that would refuse any claim outright, regardless of what happened.

Landlord insurance is a distinct product — buildings cover, landlord contents, and property owners' liability, purpose-built around the risks of a tenanted property.

This is the exclusion that catches even experienced landlords, because it's rarely front of mind until a property actually sits empty.

Standard landlord insurance will not cover properties that are left empty for more than a few weeks. Most policies void or significantly restrict cover if the property is unoccupied for more than 30-60 consecutive days.

The practical trigger points where this bites:

The fix: notify your insurer of void periods above the threshold — many offer unoccupied property extensions. This isn't automatic. If you know a property is going to sit empty longer than your policy's standard threshold, the obligation is on you to contact the insurer and arrange extended cover before the standard period runs out, not after something goes wrong.

Some insurers require that during a void period the property is properly secured — all locks in working order, windows secured. A break-in through an unsecured window during a void period may result in a reduced or declined claim, on top of the void period issue itself.

Standard landlord insurance often does not cover HMOs. A standard policy is typically designed for one household under one tenancy, which does not reflect the occupancy structure, shared facilities, fire safety requirements or licensing obligations of an HMO.

This connects directly to Edition 17's HMO licensing coverage. A landlord who has correctly identified their HMO licensing obligation, obtained the licence, and complied with room size and fire safety requirements can still find themselves with a declined claim if the underlying insurance policy was never actually switched to an HMO-specific product.

Assuming a standard buy-to-let policy stretches to cover an HMO is one of the most common causes of disputed HMO claims. The building may be the same, but the use is not — insurers underwrite HMOs differently because the risk profile genuinely is different: more occupants, shared kitchens and bathrooms, higher turnover, and greater fire risk from multiple independent households under one roof.

The specific trap: if you've converted a standard buy-to-let into an HMO — added a tenant, moved from a single family to three or more unrelated sharers — and didn't update your insurance to reflect the change, your policy may now be covering a use it was never underwritten for. Some buildings insurers exclude HMO use from standard landlord policies entirely; ensure your policy explicitly covers HMO use if the property is licensed as an HMO.

Student HMOs carry an additional wrinkle. Many providers see the word "student" and immediately hike premiums, and standard BTL policies often contain strict exclusions regarding malicious damage by tenants or unoccupied periods — exactly the profile of a student let empty over summer and Christmas, which is precisely when a standard policy's void period exclusion is most likely to be triggered.

This distinction genuinely matters and is one of the most commonly misunderstood parts of landlord insurance.

Loss of rent cover responds when an insured event — a fire, a flood — makes the property uninhabitable and you lose rental income as a result. This is tied to physical damage to the property.

Rent guarantee insurance responds when a tenant simply stops paying rent, regardless of whether any physical damage has occurred. This is the product relevant to the arrears situations covered in Edition 28.

They serve entirely different purposes and should not be confused. A landlord who has loss of rent cover and assumes they're protected against a tenant who stops paying — with no fire, no flood, nothing physically wrong with the property — will find that cover doesn't respond at all.

Rent guarantee insurance typically comes with eligibility conditions: referencing requirements, tenancy agreement standards, and in some cases a minimum tenancy term. It is not a simple add-on that pays out automatically whenever rent stops. If you didn't reference the tenant to the standard your policy requires, a rent guarantee claim can be declined even though the core problem — unpaid rent — is exactly what the product exists for.

Some rent guarantee policies also cover legal expenses to evict the tenant, including Section 8 court costs, and sometimes eviction service costs, up to a monthly cap over a set period — commonly around 8 months.

Property owners' liability insurance protects you if a tenant, visitor, or member of the public is injured because of your property. Most policies provide between £1 million and £5 million of cover; £2 million minimum is standard for most residential lets, with HMO landlords and portfolio landlords generally advised to consider higher limits.

This is worth reviewing specifically in light of Edition 20's Fitness for Human Habitation coverage. A tenant whose health has been affected by a poorly maintained property — the manslaughter-adjacent territory covered in Edition 26's gas safety edition, or the unlimited personal injury damages available under the Homes Act — is exactly the scenario liability cover exists for. A landlord with liability cover set at the minimum from years ago, never revisited as the compliance and enforcement landscape has changed, may be underinsured relative to the genuine financial exposure that now exists.

Every edition this year has emphasised a documented, dated process — deposit protection, gas safety, EICR, Right to Rent follow-ups. Insurance deserves the same treatment, but rarely gets it, because a policy renewing automatically each year doesn't naturally prompt a fresh look the way an expiring certificate does.

Worth reviewing annually, not just accepting the renewal:

✅ Never use standard home insurance for a let property — it's void from day one, regardless of how the property came to be rented out.

✅ Know your policy's void period threshold — typically 30-60 days before cover is restricted or voided. Notify your insurer before that threshold is reached if a longer void is likely.

✅ Check your policy explicitly covers HMO use if the property is licensed as an HMO — a standard buy-to-let policy is one of the most common causes of disputed claims when the property is actually an HMO.

✅ Know the difference between rent guarantee and loss of rent — they respond to different situations and are not interchangeable.

✅ Check the referencing requirements behind any rent guarantee policy — a claim can be declined if the tenant wasn't referenced to the policy's standard.

✅ Review liability cover levels annually — £2 million minimum is standard; HMO and portfolio landlords should consider higher limits given the exposure covered in earlier editions.

✅ Secure any empty property properly during a void — locks and windows in working order; an unsecured break-in during a void can reduce or void a claim independent of the void period issue itself.

✅ Re-declare property use whenever it changes — single to HMO, standard to student, owner-managed to agent-managed.

Insurance is the one area of landlord compliance where nothing forces a review — no certificate expires, no council sends a notice, no fine arrives for an outdated policy. It simply sits there, renewing quietly, until the moment a claim is needed and the gap becomes visible.

The landlords who avoid the worst version of this are those who treat their policy the same way they treat every certificate covered in this newsletter — checked annually, matched deliberately to how the property is actually being let, and updated the moment anything about that use changes.
