Understanding the Need for a Tenancy Agreement

Many landlords may feel tempted to forgo formal paperwork when renting to someone they know personally. However, the law treats these arrangements like any other tenancy. A tenancy is often created automatically once rent is paid, even without a written contract.

This means that family or friends renting your property gain legal rights and protections. For example, if you wish to regain possession but the tenant disagrees, you must follow the formal eviction process, especially as Section 21 notices will be abolished after April 2026. Additionally, landlords cannot enter the property without permission and remain responsible for repairs.

To avoid misunderstandings and protect all parties, it is advisable to have a clear, written tenancy agreement outlining the terms from the outset.

Referencing and Rent Insurance Considerations

While it may seem unnecessary to conduct tenant referencing checks for family or friends, skipping this step can limit your options. Most rent guarantee insurance policies require tenants to pass a formal referencing process or have a guarantor who does.

Rent guarantee insurance can provide valuable protection if a tenant experiences financial difficulties, covering rent payments and reducing potential strain on personal relationships. Therefore, landlords should consider referencing even when letting to people they know well.

Checking Mortgage Terms Before Letting

Landlords must review their mortgage agreements before renting to family or friends. Some lenders restrict who the property can be let to, and these restrictions often apply to standard residential mortgages as well as some buy-to-let products.

Insurance policies arranged through lenders may also include conditions about who can occupy the property. Reviewing these terms helps prevent complications with mortgage providers or insurers later on.

Tax Implications of Non-Commercial Lets

Renting to relatives or friends is often classified as a “non-commercial” or “uncommercial” let by HMRC, which has specific tax implications. Landlords must declare rental income on their Self-Assessment tax returns and pay income tax as usual.

Charging below market rent affects the expenses landlords can claim. HMRC requires expenses to be incurred “wholly and exclusively” for business purposes, so deductions are generally limited to the rent received. While taxable profit can be reduced to zero, losses cannot usually offset other income or be carried forward.

Additionally, landlords should be aware that any capital gain on selling the property may be subject to Capital Gains Tax.

Maintaining Repairs, Rules and Regulations

Legal responsibilities for property maintenance and safety apply equally when letting to family or friends. Although active inspections are rare, landlords can face significant fines if they fail to comply with regulations.

Landlords should follow best practices, including conducting electrical and gas safety tests, to ensure the property remains safe and compliant. A comprehensive checklist of legal duties can help landlords avoid overlooking important responsibilities.

Insights from Experienced Landlords

Landlords in the OpenRent Community forum have shared valuable advice based on their experiences renting to family and friends.

Nick emphasises the importance of professionalism: “If anything you’ll need to be a better landlord when renting to relatives and friends – by that I mean you need to be on top of all the paperwork and legal requirements and maintain the property – these are tenants not just mates!” He warns about the potential damage to family relationships if tenancy issues arise.

David recounts a difficult experience renting to a friend’s ex-partner, highlighting the risks of unpaid rent and property damage. His lesson: “Be business like, do be swayed by emotional links but only AFTER due diligence.”

These testimonies underline the importance of clear agreements, proper tenancy setup, and maintaining safety standards to protect both landlords and tenants.

Conclusion: Best Practices for Letting to Family and Friends

Renting to people you know requires the same diligence as any tenancy. Setting up a formal tenancy agreement, ensuring compliance with mortgage and tax rules, and maintaining the property safely are essential steps.

Following these guidelines helps prevent disputes, protects relationships, and ensures a smooth tenancy experience. Landlords may find professional tenancy setup services useful to manage these requirements effectively.
