Pest control responsibility in student housing

Short answer

There is no single rule that says “the landlord always deals with pests.” Who is responsible for mice, rats, cockroaches or bedbugs in rented student housing depends on what caused the infestation, what your tenancy agreement says, and whether the property was fit to live in. In most student lettings the responsibility falls on the landlord or letting agent, but a tenant can be responsible where the tenant’s own behaviour caused the problem.

When the landlord is responsible

The landlord will usually have to deal with the infestation in these situations.

The infestation was caused by a disrepair that the landlord must fix. For example, holes in the walls, gaps around pipes, broken air bricks, a defective roof or damaged drains that let vermin in. Under section 11 of the Landlord and Tenant Act 1985 the landlord must keep the structure and exterior in repair, so if the way in is a repair issue, sorting out both the repair and the resulting pests is the landlord’s job.

The property was not fit to live in. Under the Homes (Fitness for Human Habitation) Act 2018, which amended the Landlord and Tenant Act 1985, most residential tenancies granted or renewed on or after 20 March 2019 include an implied term that the home is fit for human habitation at the start of and throughout the tenancy. A serious infestation of vermin is one of the matters relevant to whether a home is unfit. If the property is genuinely unfit because of pests, the landlord must put it right, and you can enforce that directly in the county court.

The tenancy agreement makes the landlord responsible. Many agreements say the landlord will keep the property in a “good and habitable state,” free of pests, or contain an express clause dealing with pest control. If your agreement says this, the landlord is contractually bound regardless of the general law. Always check the wording of your own agreement first.

The infestation existed at the start of the tenancy or affects shared or common parts. If the problem was already present when you moved in, or if it affects communal areas the landlord controls (common in halls, HMOs and shared student houses), it is the landlord’s or the managing agent’s responsibility. Government guidance in the How to Rent guide confirms landlords should ensure the property is free of pests and vermin where these were not caused by the tenant’s lifestyle.

When the tenant may be responsible

You may have to deal with the infestation yourself where it was caused by something you did or failed to do. The clearest example is not disposing of rubbish or food waste properly, so that it attracts rats, mice or cockroaches. In shared student houses this is a common flashpoint. If the pests are the direct result of tenant behaviour rather than any defect in the building, the cost and responsibility can fall on the tenants.

Even then, the position is often mixed. A landlord may still need to fix any structural gap that let the pests in, while tenants deal with the housekeeping cause. The dividing line depends on the facts.

Houses in multiple occupation (HMOs)

Many shared student houses are HMOs, and larger ones need a licence. HMO management regulations place duties on the person managing the property to keep the common parts and the structure in good repair and to take reasonable steps to keep the property free from infestation. If your student house is an HMO, this strengthens the argument that the landlord or manager must deal with pests, particularly in shared areas.

The local council’s role

Local authorities have public health powers and duties in relation to pests. Councils have a duty to take steps to keep their area free of rats and mice, and their environmental health department can inspect and require action where conditions are a statutory nuisance or a health hazard.

Under the Housing Health and Safety Rating System (HHSRS), a serious infestation can be assessed as a hazard. If the council finds a category 1 hazard it must take enforcement action against the landlord, for example by serving an improvement notice. This is a useful route where a private landlord is ignoring the problem. Many councils also run a pest control service, though there is often a charge.

Purpose-built student accommodation and university halls

If you live in university-managed halls or private purpose-built student accommodation, the provider almost always retains responsibility for the building and for pest control in both your room and the communal areas, subject to the terms of your accommodation contract. Universities are also authoritative on their own housing rules and complaints procedures, so check the accommodation handbook or contract, and use the provider’s internal complaints process if they fail to act.

Practical next steps

1. Report the problem in writing straight away. This matters legally, because a landlord is generally only responsible once they know about the problem. Email or message so you have a dated record, describe what you have seen, and keep evidence such as photos, videos and any droppings or bites.

2. Check your tenancy or accommodation agreement for any clause about pests, repairs, or keeping the property habitable, and note whether the tenancy began on or after 20 March 2019 so the fitness for habitation term applies.

3. Give the landlord or agent a reasonable opportunity to act, and follow up in writing if nothing happens. Keep a clear timeline.

4. If they still do not act, contact the environmental health team at your local council and ask them to inspect under the HHSRS. This is free and can lead to enforcement.

5. Consider the university or provider complaints route if you are in halls or PBSA, and the redress scheme or property ombudsman the letting agent belongs to if a private agent is failing to deal with it.

6. Keep receipts if you have to arrange urgent treatment yourself where the landlord is clearly responsible, as you may be able to recover reasonable costs, but take care before deducting from rent because doing so incorrectly can put you at risk.

Points that change the answer

The outcome turns on a few facts worth pinning down: what actually caused the infestation and whether it links to a building defect, the exact wording of your agreement, the start date of your tenancy, whether the property is an HMO, and whether you are in a private let, university halls, or private student accommodation. If you can set out how the pests got in and what your agreement says, the responsibility usually becomes clear.
