Pest infestations in rental properties aren't just a nuisance. Left unaddressed, they can pose serious health risks and damage the property, leading to costly repairs - and in the worst cases, a legal dispute.
When pests such as rats or mice appear in a rental, the most common question is simple: who is responsible for dealing with them - the landlord or the tenant?
The answer isn't always black and white, as it depends on several key factors. This guide sets out the UK pest control laws for rental homes - including the major 2026 changes under the Renters' Rights Act - explains who's legally responsible and why, and shows how landlords and tenants can resolve pest problems quickly and fairly.
📋 Quick summary: who's responsible for pests in a rental?
- Landlords are usually responsible for infestations that pre-date the tenancy or stem from the building's condition (disrepair, holes, faulty drains), and for communal areas.
- Tenants may be responsible where their own actions caused the problem - poor hygiene, waste, damage, or failing to report it promptly.
- Act fast and in writing - a clear, dated paper trail protects both sides.
- If a landlord won't act, tenants can go to the council's environmental health team, which can compel treatment.
- Since 1 May 2026, Section 21 'no-fault' evictions are abolished - so a landlord can't evict a tenant simply for reporting a pest problem.
Why It's Important to Act Fast
Whether you're a tenant who has found evidence of pests, or a landlord who suspects an infestation or is responding to a complaint, speed is critical.
Pests such as mice and rats are known to:
- Spread infections that can affect human health (for example leptospirosis and salmonella).
- Contaminate food, causing illness or waste.
- Damage property - from chewed electrical wires and insulation to structural damage - leading to costly repairs.
- Create long-term issues that can escalate into legal action or enforcement.
- Cause problems throughout the year, giving tenants little respite.
Delaying action doesn't just worsen the infestation - it strains the tenant-landlord relationship and, if unresolved, can lead to costly repairs and legal action. In our experience, the disputes that escalate are almost always the ones where somebody reacted too late, didn't put it in writing, or never dealt with the entry points letting the pests in - so acting early, on paper, and proofing properly heads off most of them.
The Legal Framework: UK Laws That Govern Pest Control in Rental Homes
Several laws work together to keep rental properties safe, sanitary and pest-free - while still placing some responsibility on the tenant. Here's a quick summary of the ones that matter (these apply to England; Scotland and Wales have their own reformed regimes, though the core principles are broadly similar).
Landlord and Tenant Act 1985
This Act makes the landlord responsible for maintaining the structure and exterior of the property - including drains, gutters and external pipes, which are all common entry points for rodents.
Under Section 11 (repairing obligations), a landlord must:
- Maintain the structure and exterior (including drains and pipes)
- Maintain sanitation facilities
- Keep systems like heating and water in working order
If a failure to maintain the structure or exterior lets pests in, the landlord is usually responsible for resolving both the defect and the infestation.
Homes (Fitness for Human Habitation) Act 2018
This Act requires rental homes to be free from serious hazards, including vermin, and applies to nearly all tenancies under seven years. If a pest issue makes the home unfit and isn't resolved, tenants can take the landlord to court or involve the local authority, potentially resulting in compensation.
Renters' Rights Act 2025
The biggest reform to renting in a generation, the Renters' Rights Act 2025 came into force in its first phase on 1 May 2026, and it matters here for two reasons.
First, it abolished Section 21 'no-fault' evictions in England: a landlord can no longer evict a tenant without a valid legal reason and must now use a Section 8 ground for possession. All assured shorthold tenancies have also become periodic (rolling) assured tenancies with no fixed end date. In practice, this means a landlord can no longer evict a tenant simply for complaining about pests (more on that below).
Second, the Act extends the Decent Homes Standard and a version of Awaab's Law - which sets legal timescales for dealing with serious health hazards - to the private rented sector, phased in through 2026. This reinforces a landlord's duty to keep a property free from health hazards, pests included. You can read the government's overview in its guide to the Renters' Rights Act.
Environmental Protection Act 1990
A severe pest infestation can be classified as a statutory nuisance. Where it is, councils can:
- Inspect the property
- Require treatment or repairs
- Fine or prosecute a landlord who fails to meet their obligations
Prevention of Damage by Pests Act 1949
This Act gives local councils the power to intervene in rodent problems. If a landlord fails to act, the council can carry out the necessary work and recover the cost from the landlord through enforcement.
Housing Act 2004 (HHSRS)
The Housing Act 2004 introduced the Housing Health and Safety Rating System (HHSRS), under which councils assess hazards in a property. Pest infestations fall within the 'protection against infection' group of hazards, and where they amount to a serious (Category 1) hazard, the council can require the landlord to put things right.
Case Law: Read v Notting Hill Housing Trust
Precedent matters too. In one widely-cited case, a tenant lived with a rat infestation for over a year despite repeated complaints to their housing trust landlord. The court awarded £14,825 in damages - a clear signal that landlords who delay action risk significant financial and legal consequences.
Who Is Responsible for Pest Control in a Rental Property?
The law generally protects tenants, but that doesn't mean a tenant can never be held responsible. It comes down to the cause.
| Situation | Usually responsible |
|---|---|
| Infestation present before the tenancy began | Landlord |
| Pests entering through disrepair (holes, broken vents, faulty drains) | Landlord |
| Communal areas of flats or HMOs | Landlord |
| Tenancy agreement is silent on pests | Landlord (by default) |
| Infestation caused by poor hygiene or waste | Tenant |
| Entry points created by tenant damage or misuse | Tenant |
| Tenant failed to report promptly, worsening the problem | Tenant (in part) |
What Your Tenancy Agreement Says
Some tenancy agreements set out who handles pest control. If yours is vague or silent, the default legal obligations apply - which generally means the landlord is responsible unless the tenant caused the issue.
Our advice: always review your contract and raise concerns early, in writing, to keep a clear paper trail. Take photos and keep evidence of any damage, and look out for signs of pests at the very start of a tenancy - a good inventory clerk should record this.
Working Together: Tenants and Landlords
Pest problems are stressful, especially when they affect health or family life. Both sides benefit from a prompt, collaborative approach.
For tenants: report issues early, even if you're unsure; be clear and respectful in writing; and keep things clean to avoid future problems.
For landlords: respond quickly and professionally; deal with both the pest and the underlying cause; and consider preventive measures to stop it recurring.
If Your Landlord Doesn't Sort the Problem Out
If your landlord fails to act after you've reported a pest issue, you can:
- Contact your local council's environmental health department and ask for an inspection.
- Where the pests are a health hazard, the council can serve a legal notice requiring the landlord to carry out repairs or treatment.
Importantly, do not stop paying your rent unless your landlord agrees to it in writing - withholding rent without agreement can put your tenancy at risk. If you've paid for pest control yourself, negotiate a rent reduction with your landlord rather than deducting the cost unilaterally. You may also be entitled to claim compensation for significant disruption or damage to your belongings.
Can a Tenant Be Evicted for Reporting a Pest Problem?
This used to be a genuine risk. Before May 2026, some landlords responded to repair or pest complaints with a Section 21 'no-fault' eviction - so-called revenge evictions.
That route is now closed. Since Section 21 was abolished on 1 May 2026 under the Renters' Rights Act, a landlord can't evict you without a valid legal ground under Section 8 - and 'the tenant complained' isn't one. In practice, this gives tenants much stronger protection to report pest problems without fear of losing their home. (Older protections under the Deregulation Act 2015 were tied to Section 21 and have largely been overtaken by its abolition.)
It's still wise to keep written records of every complaint and response. If you're worried about your position, speak to your council or a housing adviser such as Shelter or Citizens Advice.
Pests from a Neighbour's Property
Landlords usually aren't responsible for pests originating in a neighbouring property. If you're affected by a neighbour's infestation:
- Speak to the neighbour directly and ask them to address it.
- If they won't act, report it to the council's environmental health team, which can investigate where there's a health risk or nuisance.
What About Commercial and Business Premises?
The picture is different for commercial lets. Businesses - especially those handling food - have their own duties under food safety and hygiene law to keep premises pest-free, and responsibility for treatment and proofing is usually shared between the commercial landlord and tenant according to the lease. If you run a business or manage premises, check your lease terms and your obligations under food hygiene regulations, as a pest problem here can carry compliance and reputational consequences as well as cost.
When Should You Use DIY vs Professional Pest Control?
Not every problem needs a professional. Many landlords and tenants resolve issues quickly and affordably with DIY control, especially when they act early. The most effective approach is a managed one: identify the pest, remove what's attracting it and seal entry points, use targeted traps and monitors first, and only reach for chemical treatments where needed.
At PestBuddy.co.uk, we provide:
- Ready-to-use insect and rodent control kits
- Safe, effective bait stations, sprays and traps for a wide range of pests
- Discreet, effective solutions trusted by UK households and landlords
For larger, multi-room or recurring infestations - or where there are vulnerable occupants such as young children, elderly, pregnant or immunocompromised people - a professional pest controller may still be the right call. As a rule of thumb, DIY is ideal for a minor or early problem; escalate when it has spread, keeps returning after a full treatment cycle, or needs resolving quickly and safely.
FAQs: Pest Control in Rented Homes
Is a landlord legally required to deal with mice or rats?
Usually yes, where the infestation stems from the property's condition or was present before the tenancy. Under the Homes (Fitness for Human Habitation) Act 2018 a rental must be free from serious hazards, vermin included, and tenants can take a landlord to court or involve the council if it isn't.
Who pays for pest control - the landlord or the tenant?
It depends on the cause. Landlords generally pay where the problem is linked to the building's condition or pre-dates the tenancy; tenants may pay where their own actions (poor hygiene, waste, damage) caused it. If the tenancy agreement is silent, the responsibility defaults to the landlord.
Can my landlord evict me for reporting pests?
No. Since Section 21 'no-fault' evictions were abolished on 1 May 2026 under the Renters' Rights Act, a landlord needs a valid legal ground to evict you, and complaining about pests isn't one. Keep written records of your complaints regardless.
Can I withhold rent until the pests are dealt with?
No - withholding rent without your landlord's written agreement can put your tenancy at risk. Report the issue in writing, involve environmental health if needed, and if you've paid for treatment yourself, negotiate a rent reduction rather than deducting it unilaterally.
What if the pests are coming from a neighbour's property?
Your landlord usually isn't responsible for a neighbour's infestation. Ask the neighbour to deal with it, and if they won't, report it to the council's environmental health team, which can investigate where there's a health risk or nuisance.
