This page sets out the legal position as it actually reads, with the sources linked, because the chain is short and most people in this industry state it wrongly. It is written for housing officers, repairs managers and compliance teams rather than for lawyers, and it is not legal advice.
The practical consequence is simple. A pest problem in social housing is not only a service request. It is capable of engaging a statutory covenant, and the question a provider gets asked afterwards is rarely whether it treated. It is what it knew, when, and what it did about the cause.
The chain, in four steps
Each step links the provision it rests on. Read them rather than taking this on trust.
Step 1
Exposure to pests is a prescribed hazard
Schedule 1 of the Housing Health and Safety Rating System (England) Regulations 2005 lists 29 hazards. Number 15 is “Domestic hygiene, pests and refuse”, and 15(2) is “Exposure to pests”. It sits in the same schedule as damp and mould, excess cold and structural collapse.
HHSRS Regulations 2005, Schedule 1Step 2
Prescribed hazards feed the fitness test
Section 10 of the Landlord and Tenant Act 1985 lists the matters relevant to whether a dwelling is fit for human habitation, and s.10(2) defines a prescribed hazard by reference to regulations under s.2 of the Housing Act 2004 - the HHSRS list above.
Landlord and Tenant Act 1985, s.10Step 3
Fitness is an implied covenant, and it is continuing
Section 9A, inserted by the Homes (Fitness for Human Habitation) Act 2018 and in force from 20 March 2019, implies a covenant that the dwelling is fit for human habitation at the start of the term and WILL REMAIN FIT during it. The continuing limb is the one that matters: fitness is not a condition tested once at letting.
Landlord and Tenant Act 1985, s.9AStep 4
And for social housing, the clock is set by regulation
Section 10A, inserted on 20 September 2023 by s.42 of the Social Housing (Regulation) Act 2023, implies a further covenant that the lessor will comply with prescribed requirements, and obliges the Secretary of State to make regulations requiring action on prescribed hazards within specified periods. It is enforceable through breach of that implied covenant, and a statutory defence is available. The periods themselves sit in regulations that commence in phases, so check the current ones rather than relying on any figure quoted second hand, including ours.
Landlord and Tenant Act 1985, s.10A
What follows from that, in practice
“We attended” is not the same as “we remedied”
The covenant is about the condition of the dwelling, not about the number of visits made to it. A file showing six treatments in a year and no proofing survey describes a provider that responded and a hazard that persisted, which is the worst combination to be holding when a case is examined.
The report date is the date that matters, not the contractor's
Time runs from when the landlord knew or should have known, which includes a report made to a caretaker, a repairs line or a contact centre. If those routes do not all reach the pest contractor, the provider's own records will understate what it knew and when. That gap is invisible until somebody reconstructs the timeline.
Communal causes are still the landlord's problem
Where the source is a chute, a duct, a riser or the grounds, treating inside individual flats leaves the hazard in place. Under a continuing fitness covenant the relevant question is whether the dwelling remains fit, and a resolved flat above an unresolved communal source is a temporary answer.
A defect on somebody else's title still has to be evidenced
When the reservoir is a shared sewer, the repair may belong to a water company rather than the landlord. That does not make the problem go away, it changes who the provider has to persuade - and a dated drainage survey is what moves that conversation. Without one, the same weeks get spent re-treating.
The evidence that actually defends a case
- A dated record of every report, including the ones that arrived through repairs or a caretaker rather than through the pest contractor
- What was found on each visit, not only what was applied
- The proofing survey, and what it identified as the structural cause
- Attempted access recorded and returned to the landlord, so no-access is visible rather than absorbed into a visit count
- Drainage surveys where a case has recurred at the same address
- What remains outstanding, and on whose title it sits
Common questions
Are pests really covered by fitness for human habitation?
Exposure to pests is prescribed hazard 15(2) under the HHSRS Regulations 2005, and s.10(2) of the Landlord and Tenant Act 1985 defines prescribed hazards by reference to those regulations. Prescribed hazards are one of the matters relevant to fitness under s.10(1). Whether a particular infestation makes a particular dwelling unfit is a question of fact and degree for a court, not something a pest contractor can determine, and nothing here is legal advice.
Does Awaab's Law apply to pests, or only to damp and mould?
Section 10A refers to prescribed hazards rather than to damp and mould specifically, and exposure to pests is a prescribed hazard. The requirements and the periods for acting on them are set by regulations which commence in phases, so which hazards are in scope on a given date is a matter for the regulations in force at that date. Check those directly rather than relying on a summary.
A resident reported it to their housing officer, not to you. Does that count?
For the landlord, knowledge is knowledge however it arrived. That is why the practical risk sits in the reporting chain rather than in the treatment: if a report to a caretaker or a contact centre never reaches the pest contractor, the provider is still on notice while its records suggest otherwise.
What would you actually do differently on a portfolio?
Survey at block level rather than treating the flat that complained, identify and schedule the structural work rather than repeating treatment, record attempted access and return no-access to the landlord, and issue a written report the same day showing what was found, what was done, what is outstanding and whose title it sits on.
Not legal advice. This page describes legislation as published and links every provision it relies on. Whether a particular infestation renders a particular dwelling unfit, and which requirements are in force on a given date, are questions for the regulations in force and for a qualified adviser rather than for a pest contractor.
Portfolio survey, free and without obligation
