Renting to family changes 2 things and removes neither: the letting must still be disclosed to your insurer, because a relative in occupation is still a tenancy risk, and some landlord policies restrict or price family lets differently, especially at low or zero rent. An undeclared family arrangement is one of the fastest ways to void cover.
TL;DR · LAST REVIEWED 21 July 2026
- A family member living in your property is still an occupier your insurer must know about.
- Some landlord policies exclude or restrict lets to family, particularly at below-market or zero rent.
- Mortgage rules bite too: standard buy-to-let mortgages often prohibit letting to close family.
- Regulated family lets may need a specialist regulated buy-to-let or consumer BTL product.
- A written tenancy agreement protects both sides and supports any insurance claim.
KEY FACTS
- Insurers treat undisclosed occupation as non-disclosure, whoever the occupier is related to.
- Letting to close family on a standard BTL mortgage can breach the mortgage conditions; family lets often require a regulated product.
- Zero-rent arrangements can fall outside landlord wordings built around commercial tenancies.
- Liability risk does not shrink because the tenant is a relative: injury claims can still be brought.
- Legal duties still apply in full: gas checks every 12 months, deposit protection if a deposit is taken, safety alarms.
Does renting to family count as a normal tenancy for insurance?
For disclosure purposes, yes: the insurer must know the property is occupied by someone other than you, whatever the relationship. For product purposes, not always: some landlord policies restrict family lets or treat below-market-rent arrangements differently, so the specific wording decides.
The instinct that family is different is half right and dangerously incomplete. It is right that insurers distinguish arrangements: a daughter paying market rent on an assured shorthold tenancy, a parent living rent-free in a second property, and an informal room-by-room arrangement are genuinely different risks, and wordings respond to them differently. It is incomplete because none of those differences reduces the duty to disclose. Occupation is a material fact; the surname of the occupier is not a disclosure exemption. Where landlords go wrong is running either an owner-occupier policy on a property a relative lives in, reasoning that it is still family, or a standard landlord policy without declaring that the tenant is a close relative on unusual terms. Both create claims that fail at investigation. The correct sequence is unglamorous: describe the real arrangement to the insurer, relationship, rent level and tenancy documentation included, and let them write or decline the risk. Specialist and flexible insurers cover family lets routinely; what none of them covers is an arrangement they were never told about.
Why do zero-rent and below-market family lets cause problems?
Because landlord products assume a commercial tenancy: rent, an agreement, and an arms-length relationship. Rent-free or peppercorn family arrangements sit outside that frame, so some insurers restrict them, price them differently, or route them to different products, and loss-of-rent cover becomes meaningless without rent.
The friction is structural rather than suspicious. A landlord policy is built around a commercial letting: loss of rent cover pays the rent an insured event interrupts, tenant damage cover assumes a tenancy agreement allocating responsibility, and underwriting assumes a tenant with the incentives of someone paying market rent. Strip the rent out and several components stop making sense: there is no rent to lose, the agreement is often informal or absent, and the occupier's status drifts toward that of a permitted occupier or licensee rather than a tenant, which changes the legal machinery if anything goes wrong. Insurers respond along a spectrum: some cover family arrangements on declaration without fuss, some restrict malicious damage or theft-by-tenant cover for family occupiers, and some decline the risk to specialist markets. Mortgage law adds its own layer, since letting to close family typically takes a loan out of standard buy-to-let territory into regulated territory, and running a family let on an unregulated BTL mortgage can breach its conditions. The cure for all of it is the same disclosure conversation, had before the relative moves in rather than after the kitchen floods.
What cover does a family let actually need?
The same core as any let: buildings cover for the standard perils, property owners' liability, and landlord contents where furnished. Loss of rent matters only where rent is real. What changes is the product route: declared family lets, and regulated family BTLs, sometimes need specialist policies.
Once the arrangement is disclosed, the shopping list looks familiar because the physical risks are unchanged. Fire, flood, storm and escape of water do not check the tenancy agreement before happening, so buildings cover at full rebuild value remains the foundation. Liability remains too, and deserves emphasis precisely because families skip it mentally: a relative injured by a faulty boiler or a loose stair carpet can still bring a claim, insurers and lawyers will still be involved, and the family relationship makes the scenario more painful, not less likely. Furnished family lets keep landlord contents cover relevant for the landlord's own carpets, curtains and appliances. The genuinely optional pieces track the economics: loss of rent earns its premium only where market or near-market rent flows, and rent guarantee products generally require a commercial tenancy with referencing, which informal family lets fail. The practical difference is distribution: family lets, particularly regulated ones, are better served by insurers and brokers who write them knowingly than by the cheapest comparison-site policy whose wording was never meant to include them.
How do you set up a family let so cover actually works?
Paper it like a real tenancy: a written agreement, declared rent, deposit protected if taken, gas checks every 12 months, and the insurer told the full arrangement. Formality feels unnatural in families and is exactly what makes the insurance, the mortgage and the relationship survivable.
The failure mode in family lets is informality compounding: no agreement because it felt distrustful, no disclosure because it felt unnecessary, no safety paperwork because it is only family, and then an event that turns every skipped formality into a coverage gap or a legal breach at once. The protective setup is short. A written tenancy agreement, even at concessionary rent, fixes everyone's status and supports any future claim. Rent, if paid, goes through traceable payments; if a deposit is taken it goes into a protection scheme within the statutory deadline like any other. The statutory safety duties run in full, gas safety checks every 12 months, electrical reports, smoke and carbon monoxide alarms, because the regulations do not contain a family exemption and neither do injury claims. The mortgage lender is told where the arrangement requires it, with regulated family BTL products used where close family occupy. And the insurer receives the whole picture in writing. None of this costs a relationship; all of it is what allows a family favour to survive contact with a burst pipe.
Setting up a compliant family let
- Tell your insurer the occupier is a relative, the rent level, and the tenancy terms, in writing.
- Check your mortgage: close-family lets often require a regulated product, not standard BTL.
- Use a written tenancy agreement even at low or zero rent.
- Protect any deposit in a statutory scheme within the deadline.
- Keep gas checks every 12 months, electrical reports and alarms current.
- Revisit loss-of-rent and rent guarantee options honestly: they only work where real rent flows.

Frequently asked questions
Do I need landlord insurance if my daughter rents my house?
Yes, the letting must be disclosed and insured like any other, with the family relationship and rent level declared. Some insurers restrict family lets, so a specialist policy may be the right route.
Can I let a relative live rent-free under my home insurance?
No. A property occupied by someone other than you on an owner-occupier policy is a non-disclosure risk. Declare the arrangement and use a product written for it.
Does letting to family affect my buy-to-let mortgage?
Often. Standard BTL mortgages commonly prohibit letting to close family; regulated or consumer BTL products exist for exactly this case. Check your conditions before the relative moves in.
Is loss of rent cover worth it on a family let?
Only if genuine rent is paid. Rent-free arrangements have no rent to lose, and rent guarantee products generally require a commercial tenancy with referencing.
Do gas safety rules apply when renting to family?
Yes, in full. Gas appliances must be checked every 12 months by a Gas Safe registered engineer, and the other letting duties apply regardless of the relationship.
