Introduction to HMO [2026]

Introduction to HMO: the position in 2026

Introduction to HMO is a detailed overview of houses in multiple occupation (HMOs) as regulated by UK law and updated with recent changes from the Renters' Rights Act 2025. An HMO refers to properties occupied by three or more unrelated individuals who share facilities like kitchens, bathrooms, and living spaces. This definition ensures that communal living environments meet specific safety and comfort standards for tenants.

In 2026, the importance of understanding HMO regulations is heightened due to increased focus on tenant welfare and landlord responsibilities. The introduction of new laws has shifted the balance significantly towards protecting tenants while ensuring landlords comply with stringent requirements. Understanding these changes can help both parties deal with their rights and obligations effectively, avoiding potential disputes and legal issues.

What the law says

The regulation of houses in multiple occupation (HMOs) is primarily governed by several key pieces of legislation: the Housing Act 1988, Housing Act 2004, Landlord and Tenant Act 1985, Deregulation Act 2015, and the Tenant Fees Act 2019. The Housing Act 1988 (s.8) sets out general responsibilities for landlords regarding property maintenance and repairs. Section 21 of this Act allows a landlord to end a tenancy under certain conditions without needing grounds.

The Housing Act 2004 (sections 213-215) provides the legal definition of an HMO, specifying that it includes any building or part thereof that's occupied by three or more persons who form two or more households and share basic amenities such as bathrooms and kitchens. This act also mandates licensing requirements for certain types of HMOs to ensure they meet health and safety standards.

The Landlord and Tenant Act 1985 (section 11) outlines the duties of a landlord regarding repairs and maintenance, which are important in HMO settings where communal areas require regular upkeep. The Deregulation Act 2015 introduced Section 33, further clarifying how rent can be increased within tenancy agreements.

The Tenant Fees Act 2019 prohibits landlords from charging tenants fees beyond a specified list of permitted payments, ensuring that financial burdens on tenants are kept reasonable and transparent.

These statutes collectively ensure that HMOs provide safe living conditions while protecting the interests of both tenants and landlords through clear legal frameworks and regulations.

How the Renters' Rights Act 2025 changes this

The Renters' Rights Act 2025 (RRA 2025) has significantly reshaped the situation for houses in multiple occupation (HMOs). At Introduction to HMO, one of its key provisions is the abolition of Section 21 notices, which previously allowed landlords to terminate a tenancy without cause. This change aims to provide greater stability and security for tenants.

The Act also mandates that all new tenancies are periodic from day one, eliminating fixed-term agreements and providing continuous protection against unfair rent increases or eviction tactics. Annual rent caps via Section 13 ensure that any increase in rent is reasonable and justified by market conditions rather than arbitrary landlord decisions.

the RRA 2025 has extended the Decent Homes Standard to include private rented sector (PRS) properties, including HMOs. This standard sets out clear criteria for important repairs and improvements to be made within a set timeframe, ensuring that living spaces meet minimum quality standards.

Awaab's Law, which was originally part of the Social Housing Regulation Act 2023, has been extended to cover private landlords as well. This provision requires all PRS providers, including those managing HMOs, to register their properties and themselves with a new PRS Database. Landlords must also be registered with a PRS Ombudsman for dispute resolution and oversight.

These changes collectively strengthen tenant rights while placing additional compliance obligations on landlords, ensuring that living conditions in HMOs are safer, more affordable, and better regulated.

What this means for tenants

For tenants living in houses of multiple occupation (HMOs), the Renters' Rights Act 2025 significantly enhances their legal protections and rights. Tenants may be entitled to longer-term stability through periodic tenancies from day one, eliminating the need for fixed terms that could leave them vulnerable to sudden rent hikes or unfair eviction notices.

With annual rent caps via Section 13, tenants are expected to have greater control over financial burdens associated with their accommodation. This means any increase in rent must be reasonable and justified, preventing landlords from exploiting tenancy agreements for profit.

The extended Decent Homes Standard ensures that HMOs meet minimum quality standards regarding repairs and improvements, which may be a significant relief for those previously living in substandard conditions. At Introduction to HMO, awaab's Law registration requirements also mean tenants can seek recourse through the PRS Ombudsman if their landlord fails to comply with regulations or provides inadequate service.

Tenants are advised to familiarise themselves thoroughly with these new rights and obligations, maintaining detailed records of any correspondence with landlords regarding repairs, rent payments, and living conditions. This documentation may be important in defending tenant interests against potential disputes or violations of the law.

What this means for landlords

For landlords managing houses of multiple occupation (HMOs), the Renters' Rights Act 2025 introduces substantial changes that require careful adherence to ensure compliance and avoid legal repercussions. Landlords must now register their properties with a new PRS Database and themselves with the PRS Ombudsman, providing transparency and accountability for property management practices.

The abolition of Section 21 notices means landlords can't terminate tenancies without grounds, necessitating clear justifications for eviction when necessary. This shifts the balance towards tenant protection by requiring more documentation to prove legitimate reasons for ending a tenancy agreement.

Annual rent caps via Section 13 impose limitations on how much rent can be increased each year, ensuring that any price changes are reasonable and justified rather than arbitrary profit-driven adjustments. Landlords must provide detailed explanations of rent increases based on market conditions and property improvements.

The extended Decent Homes Standard mandates regular maintenance and repairs to meet minimum quality standards, which landlords may find challenging if properties have been neglected over time. This requires proactive investment in property upkeep to avoid penalties or tenant complaints.

Overall, these changes significantly alter the dynamics between landlords and tenants in HMO settings, emphasising the importance of transparent communication, adherence to legal requirements, and regular maintenance to build harmonious living environments for all parties involved.

Common scenarios

At Introduction to HMO, Tenant with a Rent Increase Concern: A tenant suspects their landlord is attempting an unreasonable rent increase on their periodic tenancy, citing market conditions as justification without proper documentation. The tenant should review the latest Renters' Rights Act 2025 provisions and seek advice from Shelter or a solicitor to determine if the proposed rent hike complies with annual caps set by Section 13.

Landlord Facing Non-Compliance Claims: A landlord managing an HMO receives complaints from multiple tenants about inadequate living conditions, such as mouldy walls and broken kitchen appliances. The landlord must assess whether these issues fall under the Decent Homes Standard requirements and promptly address them to avoid regulatory penalties or disputes with the PRS Ombudsman.

Tenant Seeking Eviction Redress: A tenant receives an eviction notice from their landlord based on alleged non-payment of rent but believes they have valid grounds for dispute, such as recent repairs being required by law under the extended Decent Homes Standard. The tenant may seek legal counsel to challenge the legitimacy of the eviction process and explore options through the PRS Ombudsman or Housing Ombudsman.

These scenarios highlight the complexities and challenges faced by both tenants and landlords in dealing with the new HMO regulations, highlighting the need for clear communication, adherence to statutory requirements, and proactive dispute resolution mechanisms.

Evidence tenants should keep

Tenants living in houses of multiple occupation (HMOs) should maintain full records to protect their interests and rights. Key pieces of evidence include:

Correspondence with Landlord: Keep all emails, letters, and messages regarding repairs, rent payments, and other tenancy-related issues.
Rent Receipts: Save every payment record for rent and service charges.
Repair Requests: Document all requests made to the landlord for maintenance or improvements, including dates and responses received.
Photos of Living Conditions: Take pictures of any issues like mould, poor lighting, or broken appliances to demonstrate living conditions over time.

Tenants should also retain copies of their tenancy agreement, relevant legal documents such as Section 21 notices (no longer used under RRA 2025), and information about the PRS Database registration status. At Introduction to HMO, detailed records can be important when disputing landlord actions or seeking resolution through formal channels like the Housing Ombudsman or courts.

What to do if things go wrong

If issues arise within an HMO setting, tenants should follow a structured escalation path to address problems effectively:

Complaint Letter: Draft and send a formal complaint letter to the landlord detailing specific concerns and requesting remedial action.
Council Environmental Health: If immediate health or safety hazards exist, contact the local council's environmental health department for inspection and enforcement.
Deposit Scheme Dispute: In cases involving disputes over deposits, tenants may submit their claims through approved deposit protection schemes.
Housing Ombudsman: For broader issues not resolved by direct communication, escalate to the Housing Ombudsman for impartial review.
PRS Ombudsman: If problems relate specifically to PRS registration or compliance with Awaab's Law, seek resolution through the dedicated PRS Ombudsman service.
First-Tier Tribunal (Property Chamber): For more serious breaches of tenancy agreements or safety regulations, consider filing a claim with this tribunal for formal adjudication.
County Court: As a last resort, pursue legal action in the county court if all other avenues fail to resolve disputes satisfactorily.

Each step provides increasing levels of oversight and intervention, ensuring that tenants have multiple opportunities to address grievances systematically and receive fair treatment under the law.

Common mistakes to avoid

Both tenants and landlords often fall into common traps when dealing with HMO regulations:

Ignoring PRS Database Registration: Landlords may overlook registering their properties and themselves with the PRS Database, potentially leading to legal penalties. At Introduction to HMO, - Failing to Adhere to Rent Caps: Landlords might attempt rent increases above annual caps set by Section 13 of the RRA 2025, risking tenant disputes and regulatory consequences.
Lack of Documentation for Complaints: Tenants could fail to keep detailed records of repair requests or living conditions, weakening their position in formal dispute resolution processes.
Improper Use of Eviction Notices: Landlords might misuse or over-rely on eviction notices before the Renters' Rights Act 2025 changes took effect, leading to legal complications.
Neglecting Decent Homes Standard Requirements: Both parties may neglect important repairs and maintenance stipulated by the extended Decent Homes Standard, impacting living conditions and tenant satisfaction.

Avoiding these mistakes is important for maintaining compliance with HMO regulations and ensuring harmonious tenancy relationships based on mutual respect and adherence to legal requirements.
