The Housing Health and Safety Rating System (HHSRS) was introduced by the Housing Act 2004 and has remained unchanged since its introduction in April 2006. The relevant provisions are contained in Part 1 of the Housing Act 2004. Specifically, sections 1–4, which establish the HHSRS as the statutory method for assessing housing conditions and hazards, commenced in April 2006, replacing the previous ‘fitness standard’ under the Housing Act 1985.
There are currently 29 prescribed hazards in the HHSRS, ranging from Damp and Mould Growth (Hazard 1) to Structural Collapse and Falling Elements (Hazard 29). These hazards cover a wide spectrum of risks, including physiological, psychological, infection-related and accident-related hazards. Each hazard is assessed for likelihood and severity of harm to occupants, forming the basis for enforcement under the Housing Act 2004. The debate as to whether the HHSRS is the best and most appropriate standard for addressing poor housing conditions has evolved over many years.
As early as 2013, a report into the private rented sector by the Communities and Local Government Committee raised issues around the ‘particularly complex area of regulation’ that the HHSRS is perceived to be. In 2017, the Chartered Institute of Environmental Health carried out a survey of environmental health professionals (EHPs). Results indicated that although the vast majority of respondents supported updating the HHSRS, over half reported seeing hazards on inspection that were not adequately addressed by the HHSRS. In 2018, the House of Commons Housing, Communities, and Local Government Select Committee undertook a new inquiry into the private rented sector. In relation to the HHSRS, the inquiry acknowledged that the system was supported by the majority of EHPs, but the evidence indicated it to be an unnecessarily complicated one, which fails to give tenants, landlords and agents a clear understanding of the minimum standards that are expected in privately rented properties.
Since then, more recent reports have continued to highlight the challenges faced by the sector. A report commissioned by the Department for Levelling Up, Housing and Communities in September 2021, to explore local housing authority (LHA) enforcement in the private rented sector (PRS), questioned whether the HHSRS was the most effective way of assessing and tackling poor housing conditions, describing the HHSRS as ‘cumbersome’, ‘clunky’ and lacking specificity. The consensus view was that a ‘minimum standards’ approach could prove more effective and easier, both for landlords and LHAs to understand, apply and enforce.
Timeline: From scoping to reform
Scoping review and completion (2018–19)
In October 2018, the government announced that the HHSRS would be reviewed and commissioned RHE Global to undertake a scoping review. The HHSRS Scoping Review (RHE, 2019) concluded that, while there was considerable support for the strong links between health and housing that the HHSRS provides, all stakeholders would welcome simplification of the assessment process. Officers from LHAs found the system difficult to apply, and full assessments were time-consuming. Housing providers and tenants found it difficult to interpret assessment outcomes and felt that there was a discrepancy between the assessment process and other housing-based regulatory regimes governing housing safety.
The review’s findings presented three options to the government for change (Scoping Review, 2019):
Minimum updates: Review and update the current HHSRS Operating Guidance, develop a comprehensive set of worked examples, and review assessor training and competency frameworks.
Broader system enhancements: Includes Option 1 plus: Simplify hazard banding, extend and develop standards for incorporation into assessments, amalgamate or remove some hazard profiles, explore digital technology to support assessments, and review guidance for landlords and tenants alongside enforcement guidance.
Comprehensive review: Builds on Options 1 and 2 and adds: Consider adding new hazards identified during scoping, assess combined hazard effects, and undertake a full review of the statistical evidence underpinning HHSRS, including potential use of regional data.
Following RHE’s HHSRS Scoping Review, noted above, the government announced on 11 July 2019 that it would proceed with Option 2, a comprehensive review and reform of the system, stating its intention to:
Make the system easier to understand for landlords and tenants
Correct disconnects between HHSRS and other legislative standards
Facilitate effective enforcement of housing standards by local authorities.
Formal HHSRS review undertaken (2020–22)
In late 2020, the government commissioned RHE to undertake the formal review of the HHSRS, delivering the project through nine ‘outputs’ and an overarching workstream in respect of the fire hazard. These outputs were:
Reviewed and updated HHSRS Operating Guidance
Updated comprehensive set of worked examples
Review of HHSRS training requirements and competency frameworks
Simpler means of banding the results of HHSRS assessments
New minimum standards for incorporation into the HHSRS assessment process
Assessment of the amalgamation or removal of existing hazard profiles
Identification of what a HHSRS digital assessment tool would achieve
Reviewed and updated guidance for landlords and property-related professionals, and the introduction of separate guidance for tenants
Reviewed and updated HHSRS Enforcement Guidance
Review of the ‘Fire Safety Hazard’ and development of supplementary fire safety guidance.
RHE’s project delivery team consisted of highly experienced and specialist Chartered EHPs, academics and housing and industry experts, including three partner universities, namely Cardiff Metropolitan University, the University of Bristol and Middlesex University. The review involved sector-wide stakeholder consultation, housing- and health-related research and literature reviews, as well as pilot-testing of proposed HHSRS inspection and assessment changes.
Stakeholder engagement was critical to the success of the review and, as a result, to shaping the future direction of the HHSRS. Extensive consultation was undertaken, and more than a thousand stakeholders with specialist expertise and relevant interest in the HHSRS and associated housing conditions contributed, representing all regions within England. Key priorities identified through the engagement exercises included support for:
Clearer guidance and a more intuitive scoring system
A baseline approach, or ‘minimum standards,’ to complement hazard scoring
Digital innovation and tools to streamline inspections and improve data consistency
Better integration and alignment with other housing and building safety regulations.
Government objectives mirrored these priorities, making the system easier to understand, improving enforcement efficiency and ensuring consistency across housing standards.
Main review completed and government response issued (2023)
By early 2023, the review was delivered, covering the ten required outputs and workstreams. The results included revised technical and stakeholder guidance, amalgamations of certain hazards, a new traffic-light approach to banding, new baseline indicators, updates to enforcement guidance and new supplemental fire safety guidance. In September 2023, the government (DLUHC) published the Summary Report, committing to the development of updated statutory guidance, simplified scoring, baseline indicators and digital tools. The government initiated formal implementation steps, including commitments to drafting new regulations and a phased rollout. The review has produced several significant changes:
Updated operating guidance: The updated HHSRS Operating Guidance is structured into three parts: an introductory guide, a technical guide for assessors and a fire safety supplement.
Hazard amalgamation: The original 29 hazards have been reduced to 21 through the amalgamation of selected hazards. This required that the following test criteria be satisfied: 1) the causal mechanisms and spread of harm outcomes be similar, 2) the hazards must have originally been in the same hazard category, and 3) combining the hazards passed an overall test of simplifying the HHSRS assessment.
Traffic-light banding system: This would introduce a simpler, colour-coded approach to hazard scoring, making results easier to interpret whilst retaining the same hazard rating scoring calculation formula.
Baseline indicators: Baseline indicators provide a prescriptive list of proportionate building measures designed to address common health-related housing deficiencies found across the housing stock.
Updated enforcement guidance: This has been amended to reflect legislative reforms and regulatory best practices. It provides guidance to local authorities on the use of all available enforcement powers under Part 1 of the Housing Act 2004 and incorporates recent changes such as civil penalty regimes, retaliatory eviction protections and multi-agency approaches, as well as emphasising consistency in enforcement strategies and practical examples to support decision-making.
Updated landlord’s and new tenant’s guidance: A review and update of the guidance for landlords and property-related professionals and the introduction of separate guidance for tenants to allow tenants to engage effectively with the process and feel empowered to intervene or object where necessary.
Digital tools and training: Recommendations for the development of digital assessment tools (including mobile and integrated platforms) and updated training frameworks have been presented to the government as part of the HHSRS review outcomes to improve efficiency, consistency and sector-based competency and training requirements.
New suite of case studies: A modernised set of worked examples designed to illustrate the practical application of the updated hazard banding system and baseline indicators, supporting assessors and enforcement officers in applying the HHSRS2 framework effectively.
Moving towards implementation (2024–26 onwards)
More recently, the government has signalled its intention to adopt the recommendations from the HHSRS review, and new associated HHSRS regulations are anticipated, pending parliamentary scrutiny and process. HHSRS2 represents a landmark moment in housing regulation. By addressing complexity and improving clarity, the reforms will help ensure safer homes and more effective enforcement.
Ultimately, these reforms aim to create a system that is fairer, more transparent and better equipped to tackle poor housing conditions in a growing and diverse rental market. For local authorities, HHSRS2 provides tools and frameworks to streamline enforcement and improve consistency. For tenants, the changes offer greater transparency and empowerment, making it easier to understand rights and responsibilities. For landlords, the reforms promise clearer guidance on standards, reducing uncertainty and ultimately improving compliance and housing conditions across the sector. While exact dates remain subject to ministerial decisions, the anticipated timeline includes publication of revised statutory guidance and supporting materials over the coming year.
