The Housing Health and Safety Rating System is England and Wales' risk-based method for assessing all 29 categories of housing hazard — from damp and excess cold to fire, falls and electrical safety. Assessors score the likelihood and severity of harm to produce Category 1 (serious) or Category 2 hazard ratings.
Category 1 hazards trigger local authority enforcement duties and a Decent Homes failure. For providers, a current HHSRS position on every property is the foundation of compliance — it tells you what's wrong, how urgent it is, and what the law expects you to do about it.
HHSRS is the statutory assessment method in England under Part 1 of the Housing Act 2004. Local authorities must take enforcement action on Category 1 hazards, and the Decent Homes Standard requires social homes to be free of them.
Regulatory frameworks differ across the UK — see the city pages below for Scotland, Wales and Northern Ireland specifics.
A hazard scoring in bands A–C under HHSRS — serious enough that the local authority has a duty to act. Category 1 hazards also fail the Decent Homes Standard.
There's no fixed statutory interval — but regulators expect providers to know the current condition of their stock. Kaarr's recommended rhythm is a full annual assessment with quarterly checks.
No — it covers England and Wales. Scotland uses the Repairing and Tolerable Standards and Northern Ireland uses the Fitness Standard. Kaarr handles all four frameworks.
Kaarr's recommended cadence: a full 29-hazard baseline assessment before onboarding any property, quarterly walkthrough checks, and a full annual reassessment. All other statutory reports are collected and verified before onboarding completes.
