Internal flooding

Flooding from sewers is distressing and we're working hard to reduce the risk of it happening. However, it is not always possible to prevent it. Below you can find out what to do if you have sewer flooding inside your property.

Who to contact

It is important to contact your insurer immediately to tell them about any damage the flooding has caused to the interior of your property.

If you don’t, it may affect any insurance claims you need to make.

Call our 24-hour emergency number 0330 303 0368. Let us know if any nearby properties have been affected so we can help them too.

What we will do

Where possible, we will attend your property within one hour of you reporting the incident.

In the event of widespread storms and flooding, it may take us longer to reach you. We will call you to let you know we’re on our way and may also provide you with text updates, so please make sure you provide us with your mobile number.

When we see you, we will give you help and advice about what to do next. We will also ask questions about theflooding to help us understand the cause.

We will check our sewers and carry out work to address the cause as appropriate. We will carry out a basic litter pick to remove solids, where possible. One of our technicians will contact you to conduct an investigation.

What you can do

If safe to do so, please take photos of the flooded area. Pictures will help us work out why it has happened and may allow us to consider whether you’re entitled to a payment under our Guaranteed Standards Service. Keep children and pets away from the flooded areas.

How can you help?

Sewers sometimes flood during or after heavy rain if they are unable to cope with the amount of water. However, more commonly it is how we use our sewers and what we put down them that causes problems.

Many incidences of flooding could be avoided by not flushing items such as:

  • Wipes
  • Nappies
  • Sanitary towels
  • Cotton buds
  • Tampons and applicators
  • Condoms
  • Kitchen roll


Fat, oil and grease also cause blockages if poured down plugholes as it hardens when it cools.

Guaranteed standards of service payment

If your premises are internally flooded due to a failure of our drainage system, we will make a payment to you of an amount equivalent to your last two years annual sewerage charges, from a minimum of £150 for each incident.

These Guaranteed Standards Service payments are not compensation or an admission of liability. We are not able to make payments in the following circumstances:

  • The flooding was caused by you
  • The flooding was caused by exceptional rainfall events
  • If our investigation confirms the flooding was a result of a third party issue, for example surface water running over land, river inundation, private drainage or highway drainage.
