Does house insurance cover drains?

The good news is, that most building insurance (which is a form of home insurance) covers underground pipes, such as drains – as long as you are considered to have legal responsibility for them. If your policy doesn’t cover them, you can usually easily add this on.

Insurance for blocked drains and sewers will generally be for accidental damage, but not for age-related wear and tear.

Which drainage pipes are covered by home insurance?

Drains which lie within your property boundary are considered your legal responsibility. If accidental damage occurs to any of these, your insurer should cover any drainage pipe within your boundary which serves your home alone.

However, if one of these became damaged due to a lack of, or poor maintenance, your insurer will not cover the repair or replacement costs.

Do I need insurance coverage for my sewers?

If you’re wondering whether your underground sewage pipes are covered by your home insurance then it depends on where the pipes are located. If your sewers and drains connect to a public network, the good news is the water company will be responsible for issues relating to any of those plumbing lines – as long as they lie outside of your property boundary.

If your sewerage is off the mains, for example, you use a septic tank, most home insurance policies will offer you coverage for sudden accidental damages. Insurance claims related to broken sewer lines will depend on the cause of the damage. If your sewer pipes are damaged by accidental damage such as tree roots or tremors, you may be able to claim these as an insurable event. Gradual wear and tear of sewer pipes are typically excluded by most home insurance policies. Some standard homeowners insurance policies will exclude sewer line damage so be sure to check policy details.

Is there blocked drain insurance within my home insurance coverage?

Often, your building insurance will cover accidental damage to drains, but this may not include blocked pipes. Why?  Because your drains can become blocked through misuse and poor maintenance. 

If the blockage results from something out of your control, you’re more likely to be covered by building insurance.

It’s a good idea to check whether tracing, accessing and repairing a leak is covered. If you don’t feel happy with the protection offered as standard, ask to add on additional coverage, for example in the form of home emergency cover.

What is included with home emergency cover?
