A landlord we know well let a room sit empty for six weeks while waiting on a licence renewal. No harm done, or so it seemed, until a pipe burst in the flat above and flooded two rooms below. The insurer asked one question first: how long had the property been unoccupied? The answer fell outside the policy’s terms, and the claim was refused.
This is the reality of running a House in Multiple Occupation in 2026. Licensing rules have tightened, council enforcement has stepped up, and the Renters’ Rights Act has changed how tenancies end. Standard landlord insurance was never built for this kind of risk, and the gap between what landlords assume they are covered for and what the policy wording actually says is where most claims fall apart.
This guide sets out what HMO insurance needs to cover in 2026, how licensing and insurance now overlap, and where landlords most often get caught out.
What Counts as an HMO and Why It Changes Your Insurance
A House in Multiple Occupation is a property let to three or more unrelated tenants who share facilities such as a kitchen or bathroom. That single fact changes the entire risk profile of the building.
More people moving through shared spaces means more wear on communal areas, more opportunity for accidental damage, and a higher chance of a liability claim if a tenant, visitor or contractor is injured. Insurers price all of this differently to a single-family let.
A standard landlord policy is built around one household in one tenancy. Once a property becomes an HMO, that policy may exclude the extra risk entirely, even if the landlord never told the insurer the property had changed use. This is why a dedicated HMO insurance policy matters from day one, not as an afterthought once something goes wrong.
The 2026 Licensing Picture Landlords Cannot Ignore
Licensing and insurance are now closely linked. An unlicensed HMO is a compliance failure and, increasingly, a reason for an insurer to question a claim.
Mandatory, additional and selective licensing
England runs three separate licensing regimes, and a single property can fall under more than one at the same time.
Mandatory licensing applies nationally to any HMO with five or more occupants forming two or more households. Since October 2018, the number of storeys in the building no longer matters, which pulled many smaller converted properties into scope for the first time.
Additional licensing lets councils extend licensing requirements down to smaller HMOs, typically those with three or four occupants. Selective licensing is different again. It can apply to any rented property in a designated area, HMO or not, and councils use it where they have identified wider issues such as poor property conditions or high deprivation.
Additional licensing schemes now cover a large share of council areas in England, and the trend has been toward more councils adopting them rather than fewer. Landlords with properties in more than one council area may find themselves managing three different sets of rules across a small portfolio.
Section 257 conversions
Converted blocks of flats, known as Section 257 HMOs, have increasingly been brought into scope for licensing where they meet the relevant criteria. If you own a period property split into flats, it is worth checking your exact status rather than assuming the conversion sits outside licensing altogether.
Operating a licensable HMO without the correct licence is a criminal offence. Penalties include an unlimited fine in the magistrates’ court, a civil penalty that has climbed into the tens of thousands of pounds, and a Rent Repayment Order that lets tenants reclaim rent paid during the unlicensed period. None of this is covered by your buildings or liability insurance. A licensing breach and an insurance claim are two entirely separate problems, and having one does not protect you from the other.
Where Standard Landlord Insurance Falls Short
The most common mistake we see is a landlord converting a property to an HMO, or buying one that already is, and carrying on with a standard buy-to-let policy because the paperwork looks similar enough.
It rarely is. A standard policy typically will not reflect:
- The higher liability exposure of shared living spaces
- Furniture and fittings in communal areas such as kitchens and hallways
- The realistic rebuild cost of a property that has been reconfigured internally
- The specific vacancy rules that apply when a room, rather than the whole property, sits empty between tenants
If the insurer was never told the property is an HMO, they can refuse a claim outright on that basis alone, regardless of what caused the damage.
What HMO Insurance Should Actually Include
Buildings, contents and liability
A proper HMO policy covers the structure itself against fire, flood, storm and escape of water, alongside contents you provide in shared areas such as sofas, appliances and carpets. Landlords insurance needs to make sure your buildings, liability, rent, and legal position are properly protected, and liability cover sits at the centre of that for HMOs specifically. With multiple tenants and visitors moving through communal spaces, the chance of someone being injured and making a claim is higher than in a single-let property, so adequate landlord liability cover is not optional.
Loss of rent and void period cover
If an insured event makes the property unfit to live in, loss of rent cover keeps income flowing while repairs happen. This matters more in an HMO than a single-let, because you could be replacing income from several tenancies at once rather than one.
Void periods deserve particular attention. Most HMO policies apply stricter conditions once a property, or a room within it, has been empty for a set period, commonly somewhere between 30 and 60 days. That can affect cover for escape of water, theft and malicious damage specifically. If you know a room or the whole property will be empty for longer than your policy allows, tell your broker before the clock runs out, not after a claim has already been refused. Unoccupied property cover can often be arranged as an extension rather than a separate headache.
How the Renters’ Rights Act Changes the Risk Picture
The Renters’ Rights Act came into force on 1 May 2026, and its first phase abolished Section 21 no-fault evictions. Every assured shorthold tenancy in the private rented sector automatically became a periodic assured tenancy on that date, and landlords must now use Section 8 grounds, with supporting evidence, to end a tenancy.
For HMO landlords, this has practical knock-on effects. Turnover in shared houses is naturally higher than in single-family lets, and ending a problem tenancy now takes longer and requires proper documentation of the ground being relied on. That makes it more important than ever to keep tenancy records straight and to review rent guarantee and legal expenses cover at renewal, since the old fallback of a straightforward Section 21 notice no longer exists. Our guide to the Section 21 abolition covers the eviction process in full if you need the detail.
Mistakes That Still Catch Out HMO Landlords
Even experienced landlords repeat the same few errors:
- Not declaring HMO use to the insurer after a conversion or purchase, which can invalidate cover entirely
- Assuming all tenant damage is covered. Wear and tear, gradual deterioration and poor maintenance generally are not insured events
- Letting a void period run past the policy’s notification threshold without telling the broker
- Underinsuring the rebuild value, particularly where construction costs have risen since the policy was first arranged
- Treating licensing and insurance as the same task, when a valid licence does nothing to protect you if the insurance itself is wrong for the property
Reviewing your policy each renewal against these five points takes half an hour and can be the difference between a claim paying out and a claim rejected at the worst possible moment.
Getting the Cover Right for the Property You Actually Run
HMO insurance in 2026 needs to reflect three things at once: the physical building, the way tenants actually use it, and the regulatory environment it now sits inside. Licensing enforcement is tighter, penalties are higher, and the end of Section 21 has changed how tenancies conclude. None of that is solved by a generic landlord policy bought once and left untouched for years.
The safest approach is to treat your insurance and your compliance position as two parts of the same conversation, reviewed together at every renewal, and to work with a broker who understands what a genuinely mixed-use, multi-tenant property needs.

Frequently Asked Questions
Do I need a licence for a house with three tenants?
Possibly. Mandatory licensing applies to five or more occupants from two or more households, but many councils run additional licensing that lowers this to three or four occupants. Check with your local council directly, since rules vary by area.
Will my existing landlord policy cover an HMO conversion?
Almost certainly not without being updated. You need to tell your insurer as soon as a property becomes an HMO, or the policy may not respond to a claim at all.
Does a licensing breach affect my insurance?
They are separate issues. An insurer can still pay a valid claim on an unlicensed HMO, but you remain exposed to fines, Rent Repayment Orders and prosecution for the licensing breach itself, regardless of what your insurance covers.
How long can an HMO room sit empty before it affects my cover?
This varies by insurer, but 30 to 60 days unoccupied is a common trigger point for stricter conditions. Always check your specific policy wording and tell your broker in advance if you expect a longer void.
Has the Renters’ Rights Act changed what HMO insurance covers?
Not directly, but it has changed the risk landscape around tenancies ending, which makes rent guarantee and legal expenses cover more relevant at renewal than it was before May 2026.
