What is an HHSRS Assessment? A 2026 Guide for Property Professionals
The Housing Health and Safety Rating System was significantly reformed in June 2026. Here's how it works now, what the changes mean, and how to stay on the right side of enforcement.
The Housing Health and Safety Rating System (HHSRS) is the statutory framework local authorities in England use to assess the risk to health and safety from the condition of residential properties. It underpins inspections, improvement notices, prohibition orders and civil penalties, and it applies across the private rented sector.
If your knowledge of the HHSRS dates from before summer 2026, it is now out of date. The system was substantially reformed by the Housing Health and Safety Rating System (England) (Amendment) Regulations 2026, which apply to inspections beginning on or after 22 June 2026. This guide explains how the HHSRS works under the reformed system, what has changed, and what property professionals and local authorities need to understand about the enforcement that can follow.
What the HHSRS is and what it is not
The HHSRS is a risk-based assessment tool, not a fixed checklist of standards. Rather than setting out prescriptive requirements a property must meet, it asks an assessor to judge the risk that a hazard poses to the health and safety of occupants, considering both how likely harm is over the next twelve months and how serious that harm could be.
It was introduced under the Housing Act 2004 and is closely linked to the Homes (Fitness for Human Habitation) Act 2018, because HHSRS hazards feed into whether a property is considered fit to live in. Every property contains some level of hazard; the aim is not to eliminate all risk but to identify and reduce the significant risks as far as reasonably possible.
The 2026 reforms: what changed on 22 June 2026
The reforms were designed to make a complex, twenty-year-old system easier to understand and apply. The underlying standard has not been raised; a home still has to be safe, but the way hazards are described, scored and categorised has changed significantly. The key changes are:
Fewer hazards: 21 instead of 29. The prescribed hazard list was reduced from 29 to 21 by consolidating overlapping categories. For example, explosions and structural collapse are now absorbed within an expanded fire hazard definition. The risks themselves are still assessed; they are simply captured within broader categories.
New scoring bands. The old A–J letter bands have been replaced with three plainer descriptive bands based on numeric score: High (score of 1,000 or above), Medium (100 to under 1,000), and Low (under 100). Anyone still using A–J language in documentation, repair logs or correspondence should update it.
New baseline indicators. The reforms introduced baseline indicators, a prescriptive but non-exhaustive list of proportionate building measures for achieving safety against each hazard. They are not mandatory minimum standards and do not replace the assessor's judgement, but anything falling below the relevant baseline indicator should be treated as a deficiency. Usefully, they can also be used as a checklist to help a non-expert self-audit a property before a council inspection.
A new civil penalty. A new civil penalty of up to £7,000 was introduced in connection with a Category 1 (High) hazard found on inspection. This sits alongside the existing civil penalty of up to £40,000 for relevant housing offences.
Crucially, one thing has not changed: the division between Category 1 and Category 2 hazards, and what each means for enforcement.
Category 1 and Category 2 hazards
This distinction remains the heart of the system and drives what a local authority can, and must do:
A Category 1 hazard is the most serious. Where a council identifies one, it has a legal duty to take enforcement action. Common examples include serious damp and mould, excess cold, and fire or electrical risks.
A Category 2 hazard is less serious. Here the council has a discretionary power to act if it judges it appropriate but is not obliged to.
In short: Category 1 creates a duty; Category 2 creates a power. Which category a hazard falls into is determined by the score the assessing officer assigns.
What an HHSRS inspection involves
An inspection is almost always prompted by a trigger, most commonly a tenant complaint about conditions, though councils can also inspect proactively or as part of a licensing scheme. An environmental health officer or other authorised officer visits the property and assesses it against the prescribed hazards, judging for each one the likelihood and potential severity of harm and producing a score. Much of the scoring is completed afterwards using the photographs and notes taken on site. The score sets the band, the band sets the category, and the category determines what happens next.
The enforcement that can follow
Depending on what is found and the seriousness of the hazards, a local authority's response can range from informal to formal:
Informal action: advice or a request to carry out works, often where the issue is minor.
A hazard awareness notice: formally drawing attention to a hazard without requiring works.
An improvement notice: a formal notice requiring specified remedial works within a defined period. Failure to comply without reasonable excuse is a criminal offence.
A prohibition order: preventing the use of all or part of a property until hazards are addressed.
Emergency action: for hazards posing an immediate risk, a council may take emergency remedial action or make an emergency prohibition order.
For relevant breaches and offences, current guidance uses careful "up to" wording: a breach may attract a civil penalty of up to £7,000, while an offence, such as failing to comply with an improvement notice, may attract a civil penalty of up to £40,000, or prosecution and an unlimited fine. There is a right of appeal against many notices and orders to the First-tier Tribunal, and appeal windows are short, often 28 days, so early advice matters.
Why this matters for property professionals and local authorities
For landlords, letting agents and managing agents, the practical lesson is that current safety certificates alone are not a defence; a property can hold valid certificates and still contain serious HHSRS hazards. The best protection is genuine, well-documented property condition: evidence of regular checks, prompt responses to reported issues, and a clear record of repairs and communications. Where an inspection or notice is disputed, an independent expert assessment can be decisive, particularly on appeal where the council's scoring is challenged.
For local authorities, the reformed system changes how hazards are described and scored, and consistency of assessment matters more than ever. Independent HHSRS expertise can support officers dealing with complex or contested cases, provide a second opinion on scoring, or assist where capacity is stretched.
How Surrey Property Licensing can help
We provide independent HHSRS assessments and advice for property professionals and local authorities alike. Our background in environmental health and housing law means we understand the reformed system from both sides, how hazards are properly assessed and scored, and how enforcement decisions are reached.
We can carry out a private HHSRS assessment of a property, identify hazards before a local authority does, advise on the works needed to reduce risk, and provide independent expert input where an assessment or notice is contested. For local authorities, we can offer additional capacity and specialist support on complex cases.
