Understanding the causes of blocked drains
Blocked drains can occur for a range of reasons, some of which relate to how a property is used, while others stem from underlying issues within the plumbing system.
Common causes of blockages include the accumulation of grease, hair or food waste in kitchen or bathroom pipes. When not properly disposed of, items such as wet wipes or sanitary products can also clog drains and create more extensive damage throughout the plumbing system. In outdoor areas, tree roots can infiltrate underground pipes, while age-related wear or structural defects may lead to recurring blockages.
Identifying the cause of a blockage helps determine who is responsible for repairs and prevents the issue from worsening. A professional inspection can assess the plumbing system, identify the root cause and support landlords in finding the most appropriate resolution. AST Assistance can advise landlords on how to manage these scenarios in line with their legal duties.
The tenant's responsibility
Tenants have a duty to use the drainage system in a responsible manner and to maintain the drains within their rented property in good working order. This includes taking reasonable care to avoid flushing inappropriate items, such as sanitary products or wet wipes, which can easily cause blockages. Similarly, tenants should refrain from pouring grease, oils or food residues down kitchen sinks, as these substances can solidify and obstruct the pipes over time.
Most tenancy agreements set out clear expectations for the maintenance of the property, including the correct use of the plumbing and drainage systems. Tenants are expected to act promptly in reporting any signs of drainage problems to the landlord, such as slow-draining sinks or unpleasant odours. Failure to report such issues can result in further damage, for which the tenant may ultimately be held liable.
If a blockage occurs due to tenant misuse or negligence, the tenant may be responsible for covering the cost of repairs. In more serious cases, legal procedures may be required to recover these costs. AST Assistance can advise landlords on how to approach these situations and clarify where liability lies under the terms of the tenancy agreement.
The landlord's responsibility
Landlords have clear obligations under the Landlord and Tenant Act 1985, which requires them to keep the structure and exterior of a rental property in good repair. This includes responsibility for the property’s drainage system, meaning that landlords are generally accountable for drain repairs and plumbing repairs that arise from structural faults, natural wear, or damage outside the tenant’s control. Preventative maintenance plays an essential role in avoiding more serious issues, such as a collapsed drain, which can be both costly to repair and disruptive for tenants.
Under UK property law, landlords must act promptly once a tenant reports a drainage problem. Delays in arranging inspections or repairs can lead to further damage, potential health risks and legal consequences. Routine inspections and timely action can help landlords identify early signs of deterioration, protect the plumbing system and maintain the property’s habitability.
When plumbing repairs or drain repairs are required due to age, environmental factors, or a collapsed drain, the landlord is responsible for arranging professional intervention and covering the associated costs. AST Assistance advises landlords on how to meet these legal obligations, handle disputes regarding liability and manage drainage issues in line with tenancy legislation.
Resolving disputes over blocked drains
Disputes over blocked drains can arise when there’s uncertainty about whether the problem has been caused by structural faults, normal wear or tenant misuse. In these situations, clear communication and accurate documentation are necessary because they help you demonstrate that you’ve met your responsibilities as a landlord and identify where liability lies. Maintenance records, inspection reports and photographs can provide the evidence needed to show that you’ve taken reasonable steps to maintain the property and respond to issues in good time.
If you believe a blockage has resulted from tenant misuse - such as flushing inappropriate items or failing to report early warning signs - gathering detailed evidence will help support your position. Reaching an agreement through open discussion or mediation can often resolve the dispute efficiently, saving time and avoiding unnecessary legal expense.
However, if a resolution cannot be reached, court action may be required to establish liability and recover the cost of drain repairs. AST Assistance can guide you through this process, advising on how to collect supporting evidence, follow the correct legal procedures and communicate effectively with your tenant to achieve a fair outcome under tenancy law.

Blocked drain dispute FAQs
Respond promptly to any drainage issue by arranging for a qualified professional to inspect the system and identify the cause of the blockage. A professional assessment will clarify whether the problem stems from structural faults, wear and tear or tenant misuse. Once the cause has been confirmed, you can determine who is responsible for the repairs and discuss the findings with your tenant to agree on the most practical way to resolve the matter.
If a tenant fails to report a drainage issue and further damage occurs as a result, they may be held liable for the cost of repairing that damage. Making tenants aware of their responsibilities at the outset of the tenancy, and maintaining clear communication throughout, can help prevent these situations from arising and protect you from unnecessary repair costs or disputes.
If the blockage is due to tenant negligence, you may be able to charge the tenant for the cost of unblocking the drain. However, this will depend on the terms set out in the tenancy agreement. It is essential to have clear evidence of the cause and communicate this with the tenant.
Begin by attempting to resolve the issue through mediation or negotiation, as this approach is often quicker and more cost-effective than pursuing formal action. If the tenant refuses to pay for repairs after liability has been established, you may need to seek legal advice and consider taking the matter to court. AST Assistance can guide you through each stage of the legal process, helping you prepare the necessary documentation and pursue a resolution that protects your position as a landlord.
Including clear clauses in the tenancy agreement that set out the tenant’s responsibilities for drain usage and maintenance can help establish expectations from the start and reduce the risk of future disputes. If you decide to add these provisions, make sure the tenant fully understands and agrees to them before signing. This enables transparency and helps avoid complications or disagreements later in the tenancy.
