At MAXAM, we’re passionate about creating safer, healthier living environments. One of the most important tools we use to guide our work is the Housing Health and Safety Rating System (HHSRS), developed by the UK Government to identify and reduce risks to health and safety in residential properties.

The HHSRS sets out 29 key hazards that landlords, housing providers, and property managers should be aware of when assessing housing conditions. These hazards cover physical, biological, and chemical risks that can impact the safety and wellbeing of occupants.

The 29 Hazards

1. Damp and Mould Growth

2. Excess Cold

3. Excess Heat

4. Asbestos and Manufactured Mineral Fibres (MMF)

5. Biocides

6. Carbon Monoxide and Fuel Combustion Products

7. Lead

8. Radiation

9. Uncombusted Fuel Gas

10. Volatile Organic Compounds (VOCs)

11. Crowding and Space

12. Entry by Intruders

13. Lighting

14. Noise

15. Domestic Hygiene, Pests and Refuse

16. Food Safety

17. Personal Hygiene, Sanitation and Drainage

18. Water Supply for Domestic Purposes

19. Falls Associated with Baths

20. Falling on Level Surfaces

21. Falling on Stairs, Steps and Ramps

22. Falling Between Levels

23. Electrical Hazards

24. Fire

25. Flames, Hot Surfaces, etc.

26. Collision and Entrapment

27. Explosions

28. Position and Operability of Amenities

29. Structural Collapse and Falling Elements

Spotlight on Hazard 1: Damp & Mould Growth

Why it matters:
Damp and mould are among the most common hazards found in UK homes. Moisture from condensation, leaks, or poor ventilation creates the perfect breeding ground for mould spores.

The risks:

• Respiratory problems such as asthma and chronic bronchitis

• Allergic reactions and skin irritations

• Weakened immune response in vulnerable groups such as children, the elderly, and those with existing health conditions

The challenge:
While many people turn to off-the-shelf sprays or bleach solutions, these often mask the problem rather than resolving it at the root. They may remove visible staining but fail to kill the mould spores, meaning the problem quickly returns.

Spotlight on Hazard 5: Biocides

Why it matters:
Biocides are chemical substances designed to kill harmful organisms such as bacteria, fungi, and insects. While effective, many traditional biocides contain harsh chemicals that can pose serious health risks if misused or overused.

The risks:

• Skin and eye irritation

• Allergic reactions

• Harmful vapours and residues that affect indoor air quality

• Environmental contamination if not handled correctly

This creates a paradox: in trying to remove mould (hazard 1), many households introduce another hazard (hazard 5) into their living environment.

Introducing PURA+: A Safer, Smarter Mould Solution

Recognising the risks posed by both mould and conventional biocides, we developed PURA+ in 2019 - a unique, two-stage mould treatment system designed to protect both people and properties.

• Stage 1: Powerful Mould Eradication
  PURA+ penetrates deeply to kill mould spores at their root, tackling the problem where it starts, not just on the surface.

• Stage 2: Lasting Protection
  After treatment, a protective barrier is applied to actively prevent mould from returning. Unlike harsh chemical biocides, PURA+ is formulated to be effective yet safer for residents and the environment.

With PURA+, property managers and homeowners can comply with HHSRS requirements, protect tenant health, and avoid introducing unnecessary chemical risks.

Building Safer, Healthier Homes Together

At MAXAM, we understand that healthy housing is about more than just four walls. It’s about creating spaces where people can thrive. By staying informed about the 29 hazards identified in the HHSRS and using safe, effective solutions like PURA+, landlords and housing providers can play a vital role in improving living conditions and protecting communities.
