The rules here are for England.
What the duty requires
How fitness is judged
The prescribed hazards are those of the Housing Health and Safety Rating System (HHSRS), which councils also use to enforce housing standards.
Inspect and put problems right
-
Check the home before each let
Walk through it against the baseline indicators in the HHSRS operating guidance, which range from drainage and fire safety to noise and pest management. Anything that falls short of an indicator is a deficiency to assess, and ideally to fix before the tenant moves in.
-
Inspect during the tenancy
Give at least 24 hours'' written notice, visit at a reasonable time, and keep a dated record of what you find.
-
Act on reports promptly
The 1985 Act sets no fixed deadline for repairs, but unfitness that you know about and leave unrepaired lengthens the period for which you are in breach. Keep a record of what was reported, when you acted and what you did.
-
Keep the home free of Category 1 hazards
Category 1 is the most serious grade (the High band), and your council must take enforcement action when it finds one. Learn what the hazards look like so you can deal with them before an assessor does.
What happens if the home is unfit
Where a council considers that a Category 1 hazard exists, it must take enforcement action, which includes serving an improvement notice. For a Category 2 hazard it may act. Failing to comply with an improvement notice is an offence punishable by an unlimited fine. The council can instead impose a financial penalty.
From 22 June 2026, a council that first takes enforcement action over a Category 1 hazard you could reasonably have removed can also impose a financial penalty of up to £7,000.
