Understanding the Decent Homes Standard (private rented sector)
The Decent Homes Standard is a technical benchmark used to assess whether a property provides a safe and healthy environment. While the standard has existed for social housing for over two decades, its application to the private rented sector was formalised under the Renters' Rights Act 2025. The core objective is to ensure that all private rented homes are free from serious hazards and provide a reasonable degree of comfort and modern facilities.
The implementation timeline indicates that the standard will become an active, enforceable mandate for all private landlords by 2035. However, many components of the standard, particularly those related to the Housing Health and Safety Rating System (HHSRS), are already operational under existing legislation like the Housing Act 2004. The modernised decent homes standard integrates these existing safety requirements with newer obligations concerning damp and mould and minimum energy efficiency standards.
Legal framework and the Renters' Rights Act 2025
The primary legal driver for the new decent homes standard is the Renters' Rights Act 2025, which received Royal Assent on 27 October 2025. This Act modifies the Housing Act 2004 and the Landlord and Tenant Act 1985 to create a statutory link between property condition and the legality of a tenancy. Under these rules, private landlords cannot legally let a property that fails to meet the decent homes standard.
The Labour government and the preceding Conservative government both identified the need to bridge the quality gap between the social rented sector and the private rented sector. Statistical data from the English Housing Survey suggests that approximately 22% of private rented homes are currently classified as non-decent. The legislative intent is to reduce this figure by empowering local authority housing teams to intervene where properties fall below the minimum standard.
Criteria for the decent homes standard
To be classified as decent under the updated regulations, a property must satisfy four specific criteria. Failure to meet any one of these criteria results in the property being classified as non-decent.
Criterion A: Freedom from Category 1 hazards
A property must be free from Category 1 hazards as defined by the HHSRS. The HHSRS assesses 29 functional hazards, ranging from falls on stairs to the presence of serious hazards like carbon monoxide or structural instability. If a hazard is identified as Category 1, it represents a significant risk to the health or safety of the occupants, and local authorities have a duty to take enforcement action.
Criterion B: Reasonable state of repair
A property must be in a reasonable state of repair. This assessment focuses on both key building components and other building components. A property fails this criterion if:
- One or more key building components are not in a reasonable state.
- Two or more other building components are not in a reasonable state.
Key building components are those which, if they fail, could cause the property to become structurally unsound or let in the elements. These include the roof structure, external walls, central heating boilers and the electrical system.
Criterion C: Modern facilities and services
A home must provide reasonably modern facilities. This criterion is failed if the property lacks three or more of the following:
- A kitchen which is 20 years old or less and has adequate space and layout.
- A kitchen with adequate external noise insulation.
- An appropriately located bathroom and WC.
- A modern bathroom (15 years old or less).
- Adequate insulation against external noise.
- Adequate space and layout in common areas.
Criterion D: Thermal comfort
The property must provide a reasonable degree of thermal comfort. This requires the presence of both effective insulation and a functional, efficient primary heating system. In the context of the private rented sector, this often aligns with the requirements of the minimum energy efficiency standards.
Reasonable state of repair and building components
A property is considered to be in a reasonable state of repair unless it fails on the age and condition of specific building components. Landlords must monitor the lifespan of these elements to ensure the property meets the required threshold.
Key building components include:
- External walls (including damp proof courses and render).
- Roof structure and coverings.
- Chimney stacks and unsafe chimney heads.
- Windows and external doors.
- Central heating gas boilers and primary heating systems.
- Electrical systems.
If a key component is old and in poor condition, it triggers a failure. For example, a roof structure that shows extensive or serious cracking or a wall with a failed damp proof course would likely lead to a compliance failure.
Other building components include:
- Internal walls and ceilings.
- Floors.
- Sinks, baths, and kitchen units.
- Balanced gas flues.
- Cracked flat roof coverings.
- Loose or defective brackets on guttering.
A property will fail on other components if two or more are found to be in a poor state. For instance, broken or slipped slates on a minor extension combined with damaged power socket boxes would necessitate remedial work to maintain compliance with the new standard.
Minimum energy efficiency standards in the private rented sector
The intersection of the decent homes standard and energy efficiency is a focal point for modernised compliance. Private rented homes must currently meet a minimum Energy Performance Certificate (EPC) rating of E. However, government proposals suggest that the private rented sector must comply with a minimum C rating by 1 October 2030.
The thermal comfort criterion specifically mandates that landlords provide a primary heating system capable of heating the whole home. This system must be programmable and cost-effective for the occupant to run. Energy efficient homes are less likely to suffer from issues related to damp and mould, as consistent heating and insulation help manage moisture levels.
Landlords must ensure that:
- Cavity wall insulation or loft insulation is installed where appropriate.
- Heating systems are regularly serviced to maintain energy efficiency.
- Energy performance certificates are valid and updated after major works.
Failure to meet minimum energy efficiency standards can result in significant civil penalties, often separate from decent homes standard enforcement but frequently triggered by the same local council inspections.
Addressing damp and mould hazard under Awaab's law
The presence of damp and mould is a specific failure point under the modernised decent homes standard. Following the introduction of Awaab's law, which originally targeted social housing, the same protections are being extended to the private rented sector.
A home fails the standard if a damp and mould hazard is assessed at bands A to H under the HHSRS. Landlords must address the root causes of moisture ingress, including:
- Repairing leaking pipes or blockages that restrict water drainage.
- Fixing rising damp caused by compromised damp proof courses.
- Resolving penetrating damp through roof structure defects or cracked render.
- Improving inadequate ventilation or poor insulation to reduce condensation.
Local authorities identify these risks using detailed guidance. If a tenant reports damp and mould, the landlord must investigate and remediate the issue within specified timeframes. Failure to act can lead to local authority housing teams issuing improvement notices or carrying out emergency remedial action at the expense of the landlord.
Modern facilities and core services in rented homes
The requirement for modern facilities ensures that private rented homes provide a standard of living comparable to the social rented sector. This does not mean properties must be brand new, but they must meet a reasonable degree of functionality.
An appropriately located bathroom is one that is not accessed through a bedroom (unless it is an en-suite) and is located in a private area of the home. The reasonably modern bathroom criterion requires the suite to be less than 15 years old; however, a property only fails if it lacks three or more modern elements simultaneously.
Core facilities also include:
- A cold water drinking supply.
- Adequate space for food preparation in the kitchen.
- Provision for a cooker and fridge.
- Adequate insulation and privacy for the WC.
In supported or temporary accommodation, these standards remain equally applicable, ensuring that the most vulnerable in the sector are protected by the same minimum standard as the wider private rented market.
Local authority enforcement and civil penalties
Local authorities are the primary enforcement bodies for the decent homes standard private rented sector. Local councils have been granted enhanced powers to inspect properties and issue orders.
If a property is found to be non-decent, the local authority may take the following actions:
- Improvement Notices, requiring the landlord to carry out specific repairs within a set timeframe.
- Hazard Awareness Notices, advising the landlord of a minor risk that does not yet require mandatory action.
- Emergency Remedial Action, where a Category 1 hazard poses an imminent risk, the council may fix the issue and bill the landlord.
Civil penalties where local authorities can issue on-the-spot fines of up to £7,000 for certain breaches, with maximum civil penalties for serious or repeated non-compliance reaching £40,000.
The maximum penalty for non-compliant landlords has increased, and courts can now reclaim up to two years' worth of rent through Rent Repayment Orders if a landlord fails to comply with an improvement notice.
Risks of non-compliance for private landlords
The consequences of failing to meet the new decent homes standard extend beyond simple fines. The legal and financial risks can impact the viability of a rental portfolio.
- Rent Repayment Orders can be applied for by tenants or local authorities if the landlord fails to comply with an enforcement notice.
- Possession Restrictions may occur as non-compliance can be used as a defence by tenants in possession proceedings.
- Banning Orders may be issued for the most serious violations, preventing the individual from letting property or engaging in property management.
- Property Devaluation is a risk as homes that do not meet the standard are more difficult to mortgage or sell.
Landlords must also consider the risk of significant hazards, such as leaking oil tanks or electrical systems that cannot withstand reasonable force, which could lead to criminal prosecution under the Housing Act 2004.
Compliance timeline for the private rented sector
The transition to the new decent homes standard is phased to allow private landlords time to modernise their portfolios.
- October 2025: Renters' Rights Act 2025 received Royal Assent, establishing the legal basis for the standard in the private rented sector.
- 2030: Deadline for meeting updated minimum energy efficiency standards, likely EPC C.
- 2035: Full implementation of the decent homes standard across all private rented homes in England.
Despite the 2035 deadline for the full standard, safety-related elements such as HHSRS Category 1 hazards are already enforceable.
