Bed bugs when you rent: who has to deal with it

The short answerIn most of the UK the landlord is responsible for bed bugs that were present when you moved in, or that got in through disrepair, or that affect a licensed HMO or furnished let. If the infestation clearly started during your tenancy and nothing about the building let it in, the landlord can argue it is yours to sort. Report it in writing on the day you find it, keep photos, and do not sign anything that blames you.

Bed bugs in a rented home turn into an argument about money almost immediately. The landlord says you brought them in. You say they were there when you arrived, or came through the wall. Meanwhile the bugs keep biting. This guide sets out who is responsible in each part of the UK, what the housing bodies actually say, and how to protect yourself in writing.

We are a directory of pest control firms, not lawyers. Where this matters, we link to Shelter, Citizens Advice and the government pages so you can read the rules for yourself.

The principle that applies everywhere

Across the UK, the question comes down to cause. If the infestation was present when the tenancy began, or got in because of something the landlord should have fixed (gaps in walls, floors, pipework, shared ducts), the landlord is normally responsible. If it arrived during the tenancy through your own belongings, luggage or furniture, and the building did nothing to let it in, the tenant may be.

In practice, cause is hard to prove either way. That is why timing and paperwork decide most disputes, and why the first 24 hours matter.

England and Wales

Shelter England’s guidance on pests in rented homes is the clearest starting point. The landlord must deal with an infestation when:

• it was there at the start of the tenancy;
• it is caused by disrepair the landlord is obliged to fix;
• the tenancy agreement says the landlord is responsible for pests;
• the property is let furnished and the furniture is the source.

Under the Homes (Fitness for Human Habitation) Act 2018 in England, a home must be fit to live in throughout the tenancy, and a serious pest problem can make it unfit. Wales has similar fitness requirements under the Renting Homes (Wales) Act. If the landlord does nothing, the council’s environmental health team can inspect under the Housing Health and Safety Rating System. The GOV.UK tenant guide to HHSRS lists “domestic hygiene, pests and refuse” as one of the hazards they assess.

Citizens Advice adds a practical point: if the landlord refuses and you arrange treatment yourself, you may be able to claim the cost back, but only if you have told them in writing first and given them a reasonable chance to act.

Scotland

Private landlords in Scotland must meet the Repairing Standard. The Scottish Government’s statutory guidance, updated in 2024, requires the house to be wind and watertight and reasonably fit for human habitation, with the structure and fixtures in a reasonable state of repair. Shelter Scotland’s pests page says that where an infestation results from a repair problem, or was present when you moved in, the landlord should deal with it.

If the landlord will not act, Scottish tenants can apply to the First-tier Tribunal for Scotland (Housing and Property Chamber), which can order repairs. mygov.scot explains the process for private tenants. Firms on the Glasgow page and the Edinburgh page are used to dealing with tenement blocks, where the same infestation often spans several flats and several landlords.

Northern Ireland

Northern Ireland has its own rules. nidirect’s page on landlord and tenant responsibilities sets out that the landlord must keep the structure and exterior in repair, and the fitness standard for rented homes is enforced by district councils. nidirect’s housing standards page explains how to ask the council’s environmental health department to inspect. The Private Tenancies Act (Northern Ireland) 2022 strengthened the requirements on landlords. If you rent in Belfast or elsewhere in Northern Ireland, report to the landlord in writing and, if nothing happens, to the council.

HMOs and shared houses

A house in multiple occupation (HMO) is a property shared by three or more people from more than one household. GOV.UK sets out when an HMO needs a licence in England. Licensed HMOs have conditions attached, and most councils expect the landlord or managing agent to deal with pests in shared areas and usually in the whole house. In Scotland and Northern Ireland HMO licensing is stricter still.

In a shared house, you also cannot sort bed bugs on your own. Treating one bedroom while the one next door is untreated is wasted money. The landlord is the only person who can coordinate the whole property, which is one more reason to push the responsibility that way. Firms covering student areas, such as those on the Leeds list, the Sheffield list and the Nottingham and Midlands pages, quote whole-house treatments for exactly this reason.

Social housing

Council and housing association tenants should report bed bugs to the landlord’s repairs line. Many large social landlords have a pest contract and will treat without charge where the tenancy agreement puts pests on their side. Some charge where they decide the tenant caused the problem. Ask for the decision in writing. Southwark, Islington and other London boroughs set out their position on their own pest control pages, which our council pest control guide links to.

What to put in writing

Do this on the day you find the bugs, before you ring anyone.

1. Email or message the landlord or agent. State the date, what you found, where, and that you are asking them to arrange professional treatment. Keep it factual.
2. Photograph the evidence: live bugs, shed skins, blood spots on sheets, dark marks on mattress seams. Put the date on the photos.
3. Say when you first noticed bites, if you had any, and whether you have travelled or brought second-hand furniture in. Do not speculate about cause.
4. Ask for a written response within a set number of days.
5. If a technician visits, ask for a copy of the report. It will say how established the infestation is, which is the nearest thing to evidence of when it started.

Keep every message. If this ends up in a deposit dispute, the record is what decides it.

Deposits

Landlords in England and Wales sometimes try to deduct treatment costs from the deposit at the end of the tenancy. GOV.UK’s tenancy deposit pages explain that deductions can be challenged through the deposit scheme’s free dispute service, and the landlord has to show evidence that the tenant caused the loss. Scotland and Northern Ireland have their own deposit schemes with similar dispute routes.

Do not accept a deduction for bed bugs you reported promptly and in writing. Do not sign anything that says you caused the infestation unless you know that you did.

If you decide to pay yourself

Sometimes a tenant pays simply to make it stop. If you do, choose carefully. Ask the firm for a written report that describes the extent of the infestation, since you may need it later. Use a firm on the BPCA or NPTA register. Our guides to what happens during treatment and treatment costs will help you judge a quote.
