Housing Health and Safety Rating System. HA 2004.

• This requires landlords or letting agents to conduct a risk assessment on all properties in accordance with a 29 point checklist and
• to take steps to minimise such risks.

1. PHYSIOLOGICAL REQUIREMENTS:
   Hydrothermal Conditions:
   1. Damp and mould growth
   2. Excess cold
   3. Excess heat
2. Pollutants (non-microbial):
   4. Asbestos (and MMF)
   5. Biocides
   6. Carbon Monoxide and fuel combustion products
   7. Lead
   8. Radiation
   9. Un-combusted fuel gas
   10. Volatile Organic Compounds
3. Housing Health and Safety Rating System (HHSRS):
   Space, Security, Light and Noise:
   11. Crowding and space
   12. Entry by intruders
   13. Lighting
   14. Noise 
4. PROTECTION AGAINST INFECTION:
   Hygiene, Sanitation and Water Supply: 
   15. Domestic hygiene, Pests and Refuse
   16. Food safety
   17. Personal hygiene, Sanitation and Drainage - e.g. includes risk from Legionella - e.g. where water rests in pipes undisturbed for a time at certain warm temperatures, bacteria accumulate, so when arriving at a property after a possible period of non-occupancy flush toilets since inhaled vaporised droplets can be harmful - particularly to vulnerable people with lowered immune systems, e.g. during or following illness..
   18. Water supply for Domestic Purposes - following a vacation or upon first arrival run taps for a short time before drinking to ensure fresh and free of Legionnaires' disease. 
5. PROTECTION AGAINST ACCIDENTS:
   Falls: 
   19. Falls associated with baths, etc.
   20. Falls on the level
   21. Falls associated with stairs and steps (ensure adequate handrails)
   22. Falls between level 
       Electric Shocks, Fires, Burns and Scalds: 
   23. Electrical hazards (fit trip switches)
   24. Fire(provide smoke and heat detectors, fire blanket, etc.) fire certificates evince due diligence.
   25. Hot surfaces and materials 
       Collisions, Cuts and Strains: 
   26. Collision and entrapment
   27. Explosions
   28. Ergonomics (human factors affecting the ability to function, e.g. opening a fire door with no physical strength to push the door open if elderly). Leydon Lettings has just agreed to alter a period property which is not dangerous per se but presents a risk to the tenant who suffers from dizzy spells.
   29. Structural collapse and failing element
