Pests In A Rented Home: Who Is Responsible?
General information rather than legal advice, and the short answer is that it usually turns on how they got in.
The general rule
Structure Versus Housekeeping
Broadly, and with plenty of exceptions: defects in the building that let pests in are the landlord's, and waste and cleanliness inside the property are the tenant's.
A gap at the roofline, a broken airbrick, a defective drain, a rotten door threshold - structure, and the landlord's. Bin bags left in the hall, food waste not put out, a kitchen that has not been cleaned - housekeeping, and the tenant's.
Most real disputes are somewhere in between, which is why the documentation matters more than the argument.
The law it rests on
What Actually Applies In England
Several things at once, and they do different jobs.
Landlord and Tenant Act 1985, section 11 puts the repairing obligation for the structure and exterior on the landlord in most residential tenancies. A pest problem caused by disrepair follows the repair.
The Homes (Fitness for Human Habitation) Act 2018 requires a rented home to be fit to live in for the whole tenancy, and a serious infestation can make it unfit. It gives the tenant a direct route to court rather than depending on the council.
The Housing Act 2004 and the HHSRS let the local authority assess hazards, and "domestic hygiene, pests and refuse" is one of them. A council can require a landlord to act.
The Prevention of Damage by Pests Act 1949 is the one people quote wrongly. It places a duty on the local authority to keep its district free of rats and mice so far as practicable, and it lets them require an owner or occupier to act. It is not a direct tenant-versus-landlord remedy.
Verified against Shelter's published guidance rather than written from memory.
In practice
What To Do, In Order
Report it in writing, immediately. Not a phone call - an email or a message, so there is a date. This is the single most useful thing a tenant can do, and it costs nothing.
Take photographs. Of the damage, the droppings, the gap, the bites, whatever there is, with something for scale.
Give the landlord a reasonable chance to act. What is reasonable depends on severity: rats in the kitchen is not the same as ants in the garden.
If nothing happens, go to the council. Environmental health can inspect under the HHSRS and require action.
For landlords the mirror image applies: act on a written report quickly, get a survey that says what the cause was, and keep the report. A finding that says "entry via defective airbrick" or "attributable to waste storage" settles a deposit dispute far better than either side's recollection.
HMOs and student lets
Where It Gets More Complicated
In a house in multiple occupation the landlord's duties are wider - communal areas, waste storage and the fabric are all theirs - and licensing conditions often say so explicitly. In Canterbury in particular, where a large share of the stock is student HMOs, the bins and the communal kitchen are where most of it starts.
The changeover is the moment that solves it. An empty house can be surveyed, treated and proofed properly in a fortnight, and it costs the same as doing it badly in November with six people living there.
In a block of flats the communal parts belong to the freeholder and neither landlord nor tenant can authorise work there, which is a separate article.
Common Questions
My landlord says it is my fault. What do I do?
Get a survey that states the cause. A written finding that says entry was via a structural defect is worth more than either side’s opinion.
Can the council make my landlord act?
They can inspect under the HHSRS and require action where there is a hazard. Report it to the landlord in writing first.
I am a landlord. How do I protect myself?
Act on written reports quickly and keep the survey. A dated finding about the cause settles most deposit disputes before they start.
