I have a blocked drain, but who is responsible?

Blocked drains are one of the most infuriating and common plumbing problems a person is likely to experience. In some cases there will be a shared drainage responsibility, other times it will be the sole responsibility of one party.

It can be very stressful to work out who is liable to pay for any repairs. Luckily with our extensive experience we’ve seen our fair share of examples, so we can help.

As with many facilities that the public use, the responsibility will depend on factors including the location of the drain and the situation of the occupier within the property.

What do I do if I own my property?

Responsibility for a blocked drain that is located on a person’s property will depend on its location. Most of the drains that a water company must maintain are on public land, outside of the private property boundary.

The property owner must maintain their own drains when they have a blockage. A property that relies on a private sewer system will also be the responsibility of the owner.

Should there be damage to the drain then the repair for the broken drain also falls with the property owner. In many cases drain repairs can include excavations and relining to restore the pipe and ensure any waste flows smoothly in future.

Shared drainage responsibility

Property owners in flats and other buildings that share drainage facilities will commonly have some form of management company that takes responsibility for building maintenance. This management or caretaker company will usually pay for drainage issues in the building with maintenance fees.

However, responsibility for drains inside individual flats may fall with the individual owner.

Tenants usually have the ability to pass on repair and maintenance costs for their property, including drains. This can help alleviate a lot of financial pressure for tenants.

However, there may be a stipulation in the tenancy agreement requiring a tenant to pay for, or contribute to, any costs. There will be terms in the tenancy agreement that will show tenants whether they are liable for any repairs or maintenance.

If people are renting, or considering renting, a property that may have drainage issues they can do the following:

  • Check the tenancy agreement.
  • Ask the landlord or letting agent.

Who is responsible for drain covers?

A drain cover, the round flat covering of a manhole, may or may not be the responsibility of the property owner.

If a council or water company manages or maintains the drain then it is probably a public drain. This is the case even if it is on a private piece of land, such as a driveway.

Private drains are the responsibility of the property owner. People can check their drain covers for signs it is a public drain if they are unsure. Signs include the presence of the name of a water company on the cover.

I have a blocked sewer drain, who is responsible?

In some cases certain types of drain will be the responsibility of the council or local water company. The types of drains that are not the responsibility of the property owner include sewers and lateral drains.

A lateral drain is a waste pipe, they are usually outside of a private property boundary and go under public roads. The sewer will in turn collect the waste and water from these lateral drains.

People should contact their water company if they are unsure whether they are responsible for a blocked drain. According to Citizens Advice, it may be possible to ask the sewerage company to take responsibility for a private sewer or lateral drain. This depends on the condition and standards the company requires.

What actually causes a blocked drain?

The cause of a blocked drain will depend on the type of drain and its location.The most common causes of a blocked drain include the following:

  • Plant matter: In some areas garden plant or tree roots can reach drains and grow into them. Due to the water content, plant roots may be attracted to a drain, which may cause a blockage.
  • Hair: Hair can block a drain in places such as a shower or bath. This blockage usually occurs within the internal drain, it is preventable by regularly cleaning the area around the drain and using a hair trap.
  • Fat, oils and grease: This is common in restaurant kitchens and may clog sewers too. Fatty build-ups stick together and can make a drain clog.
  • Other objects: Wet wipes, sanitary pads and other items that people may flush down a toilet can block a drain quite significantly. Prevention simply relies on not flushing such items.

Whatever the cause, the problems that can arise from blocked drains include overflowing water and inadequate drainage as well as potentially foul smelling odours.
