Sewer flooding

If the flood is coming from a river, please contact the Environment Agency on 0800 807 060.

Flooding from groundwater can happen when the level of water within the rock or soil that makes up the land surface (known as the water table) rises.

The level of the water table changes with the seasons due to variations in long term rainfall and water abstraction.

If you're affected by groundwater flooding, contact your local council (opens new window).

If the flooding occurs due to a blocked gully, which is a slotted drain usually found close to the kerbside)

Please contact your local council (opens new window).

When you call us, we may be able to diagnose, over the phone, if the problem is on your private pipework.

If it is on your private pipework, it’s your responsibility and you’ll need to arrange the repair. We’ll support and advise you as much as we can over the phone. Find out more about sewer pipe responsibility.

This means the sewer flooding is coming from your private drain within your property boundary. It could be caused by a blockage, from putting wrong things down the toilet or sink or damaged private pipework.

We recommend you contact your insurance company, as they may be able to arrange a clean-up and replace damaged items. You can hire a plumber or a drain clearing company to help you.

If the sewer flooding is inside your property, turn off your gas and electric. It can help to prevent further damage.

It's important you get in touch with your home insurer to let them know of a flooding incident. If you've suffered any loss or damage, your insurer will let you know what to do next to make sure the terms of your policy are met.

When the problem is our responsibility, we aim to visit within two hours if it's inside your property. If it’s outside your property we aim to visit within four hours

Sewer flooding inside the property, is given priority. However, in the event of severe weather and widespread flooding, it can take us longer. If we do run late, we'll let you know and give you an estimated time of arrival.

Once on site, we'll aim to remove any blockage and stop any sewer flooding. We’ll carry out an investigation to help us find out what caused the flooding. We’ll update you on our progress and provide you with timescales for fixing the cause of the flooding.

After external sewer flooding, we will wash down and disinfect all hard standing areas, such as paths, patios or yards. If the ground is waterlogged, we may need to leave the clean-up for a day or two to avoid disturbing the ground and spreading the contamination.

If the sewer flooding is inside your property, we can help clean it up. This will be completed by the end of the next day. If this isn’t possible, we’ll discuss this with you and keep you updated.

In the most serious instances, you’ll need to complete any clean up with the support of your insurance company. To help with your costs, we'll pay for your insurance excess up to £500 where this is necessary.  

For customers who are experiencing financial hardship and are unable to obtain household insurance, we'll contribute up to £500 towards damaged house contents. Each application is considered carefully, and we do reserve the right to carry out investigations to assess the validity of your application.
