Pest Control for a First-Time Landlord: What to Put in Place Before the First Tenancy
Pest control for a first-time landlord is mostly a job done before anyone moves in. Commission an inspection that dates the property's condition, proof the obvious entry points, photograph everything into the check-in report, and write a tenancy agreement that reflects the law rather than contradicting it. Reactive callouts are what happens when those four steps are skipped.
What should a landlord do before the tenant moves in?
Three things, in this order: a pest inspection, proofing at the obvious entry points, and photographs in the inventory or check-in report. The inspection matters most, because it dates the property's condition. A dated set of findings and images taken before handover — the loft, under the kitchen units, behind white goods, the external walls at ground level — is the document that later settles whether an infestation existed at the start of the tenancy or arrived during it.
Proofing is the physical half of the same job. The obvious entry points are gaps where pipes and cables pass through walls, broken or missing airbricks, gaps under external doors, damaged soffits, and open gaps behind a fitted kitchen.
What should a first-time landlord put in place, and when?
Seven actions cover the pest risk in a first let, and each one protects a different position.
| What to do | When | Why it protects you |
|---|---|---|
| Pest inspection with a written report | Before handover, during the void | Dates the property's condition, so a later infestation can be placed in time |
| Proofing of pipe entries, airbricks, soffits and door gaps | Before handover | Removes the entry routes, and evidences compliance with the repairing obligation |
| Photographs in the inventory or check-in report | At handover, signed by the tenant | Turns condition into agreed evidence rather than your word against theirs |
| Drain check where there is any rat history | Before handover | A defective drain is a building fault that presents as a pest problem |
| Tenancy clauses on food and refuse storage, and on reporting | In the agreement | Sets the tenant's conduct duties without removing your own |
| A named contractor and reporting route given to the tenant | At handover | Shortens the gap between first sighting and first visit |
| Scheduled proofing review between tenancies | Every void period | Deals with the cause rather than the symptom, and costs less than repeat callouts |
What belongs in the tenancy agreement, and what cannot be put there?
The agreement can allocate conduct and reporting duties to the tenant, and it cannot remove the landlord's repairing obligation. A landlord must keep the structure and exterior of the dwelling in repair, along with the installations for water, gas, electricity, sanitation and heating. That obligation is implied into every short residential tenancy, and a term purporting to exclude it is not effective: a clause making the tenant responsible for "all pest control" does not transfer an infestation that entered through disrepair.
Unfair terms are the second limit. A tenancy agreement is a consumer contract, so a term in it can be challenged as unfair, and every term must be expressed in plain, intelligible language. A clause making the tenant liable for every infestation regardless of cause is the kind of blanket allocation that invites challenge.
What does work is specific and behavioural. Require food to be stored in sealed containers, refuse to be bagged and placed in the provided bins rather than accumulated indoors, and any sighting of rodents or insects to be reported without delay — that reporting clause is the one that most often saves money.
How does responsibility for an infestation actually divide?
Responsibility follows the cause, not the wording of the agreement. Where pests enter because the building is in disrepair — a broken airbrick, an unsealed pipe entry, a defective drain, a gap under a door — it is the landlord's, because those items sit inside the repairing obligation for the structure, exterior and installations. Where an infestation is caused or sustained by how the property is used, such as food waste accumulating indoors, it usually falls to the tenant.
Two situations sit between. An infestation present at the start of a tenancy is the case the pre-tenancy inspection exists for: without dated evidence, the argument is unwinnable in either direction. And an infestation arriving from next door, common in terraces and converted flats, is nobody's conduct problem and everybody's proofing problem.
What does the HHSRS pest hazard mean for a landlord?
The HHSRS pest hazard means a council can assess a serious infestation in your rented property as a hazard and take enforcement action against you. The Housing Health and Safety Rating System (HHSRS) is the method a council uses to rate categories of housing hazard, and domestic hygiene, pests and refuse is one of them. An Environmental Health Officer inspects, scores the hazard, and where the score is high enough the council can serve an improvement notice specifying the works required and the period allowed for them. Failing to comply with such a notice is an offence. The assessment looks at the property's condition rather than at whose fault the infestation was, so "the tenant caused it" is not an answer to the notice.
A documented response is the practical protection against an enforcement notice. A landlord who can produce the inspection report, the attendance date, the treatment, the proofing completed and the follow-up findings has addressed the hazard on paper as well as in fact.
One further duty applies from the start: an owner or occupier of land must notify the local authority in writing where rats or mice are present in substantial numbers.
Can you enter the property to deal with pests?
Not without notice and agreement, however urgent the pest problem feels. A tenant has the right to quiet enjoyment of the property, and the landlord's implied right of access is a right to enter at reasonable times of day to view the condition and state of repair, on at least 24 hours' notice in writing. It is not a right to let a contractor in to carry out work unannounced. Entry without agreement risks a harassment allegation rather than a resolved infestation.
So arrange the visit with the tenant rather than around them. Ask which days they can give access, tell them who is attending and what the technician needs to reach, and confirm in writing. Where a tenant refuses access altogether and a hazard exists, that is a separate legal problem needing advice, not a set of keys.
Speed is available on the assessment side once access is agreed. 247 Pest Control states that same-day attendance is available across London and that it responds to emergency enquiries 24/7, while noting that attendance time cannot be identical for every call. An attending technician confirms the species, recommends the treatment the property needs, and gives the earliest date it can be booked.
What is different if you are letting a flat in a block?
In a flat, the freeholder or managing agent controls the common parts, which is where most of the pest problem usually lives. Your repairing obligation runs to the demised premises, while the bin stores, risers, roof voids and external walls that rodents actually use are typically the freeholder's under the lease. Treating inside the flat while the shared route stays open produces a repeat visit rather than a result.
The practical sequence is to read the lease to establish where the demise ends, report the problem to the managing agent in writing, and keep the correspondence. In a Victorian terrace converted into flats, common across Hackney and East London, floor voids and pipe boxings connect the whole structure, so mice found in one flat are a building problem for the freeholder. Where the agent will not act, treat the interior, proof your own boundary at pipe entries and floor voids, and record what you asked for and when.
Is scheduled proofing between tenancies better than reactive callouts?
Yes, for two reasons: cost and effect. Pest control for a first-time landlord becomes far cheaper once it moves into the void period, because a void has no occupants and no furniture. Proofing can then be done properly — kitchen plinths removed, pipe boxings opened, gaps sealed with wire wool bedded in sealant or a metal collar rather than expanding foam alone, which mice chew through. It is also completed faster, because a technician in an empty flat is not working around a tenant's day.
Reactive callouts also treat the symptom on repeat. A mouse infestation that returns each autumn is not bad luck; it is an unsealed entry point with a seasonal trigger. Proofing is the only spending that reduces the need for the rest. 247 Pest Control lists proofing alongside inspection, treatment and bird proofing among its services across Greater London, so ask for proofing by name when booking a void-period visit.
What else do first-time landlords ask about pest control?
Am I legally required to have a pest inspection before letting?
No, so it is protective rather than mandatory. But the Housing Health and Safety Rating System (HHSRS) rates domestic hygiene, pests and refuse as a housing hazard, so a council can assess an infestation in your property and require works. A dated report plus photographs evidences the condition at handover, which is what settles a later dispute.
Can I make the tenant pay for pest treatment in the agreement?
Only where the tenant's conduct caused the problem, and only through a term that is fair and clearly written. The landlord's repairing obligation for the structure, exterior and installations cannot be excluded by agreement, and an unfair term in a tenancy is not binding. Charge for conduct that caused an infestation, never for a building that let one in.
How much notice do I have to give before a pest control visit?
At least 24 hours in writing, at a reasonable time of day, and in practice by agreement rather than by notice alone. The landlord's implied right of access allows entry to view the condition and state of repair on that basis, not to carry out works unannounced. Confirm the appointment, the contractor and the access arrangements in writing.
What should I do if a tenant reports mice in the first week?
Book an inspection immediately and produce your pre-tenancy report. A sighting in week one, set against a dated inspection showing no evidence at handover, points to an entry route rather than to tenant conduct, and the answer is proofing plus treatment. Handle it quickly and in writing: a documented early response keeps a minor issue from becoming a dispute.
