Blockages in pipes can be nasty, stopping waste from leaving your property.
You may have a blockage if:
- You find it difficult to flush your toilet.
- Your sink or bath empties very slowly.
- You notice a bad smell coming from your drains.
When wastewater is unable to flow away it can come back up from the toilet or sink, flooding your home. It's easy to avoid blockages, just remember to bin any item that's not pee, poo, or toilet paper.
What causes blockages?
Sewers are only designed to take water from your toilets, sinks, baths and showers along with human waste and toilet tissue. Everything else should be put in the bin.
Blockages are normally caused by:
- Fat, oil and food leftovers that solidifies in pipes.
- Wet wipes – even the ones labelled ‘flushable’ block your pipes.
- Sanitary items, including towels and tampons.
How do I know if the blockage is in my home?
If the blockage is in your home, it’s your responsibility to unblock it. These signs may indicate it's in your home:
- Your neighbours aren't experiencing problems with their drains.
- Your property doesn’t share a drain with any other property.
- There’s no other flooding in the local area.
- Your upstairs facilities are impacted but downstairs is working - this suggests an internal blockage.
- If you lift the manhole cover outside your property and the drain is clear, it's likely that suggesting the blockage is within your home.
Who is responsible?
We repair and clean the pipes that carry wastewater from your street to our treatment works. Property owners are responsible for the pipes in the homes and the ones connecting to our sewers.
A blockage may be the property owner’s responsibility if:
- Only one home is experiencing problems
- The property doesn’t share a drain with any other property
- There is no other flooding in the local area.
It may be our responsibility if we have public sewers in the area and at least one of the following applies:
- The problem is outside your property boundary
- More than one property is experiencing problems
If you think you have a blockage within your drains or sewer, we recommend you contact a plumber. Many home insurance providers or home protection includes drainage cover, so they may also be able to help.
If you think the blockage is in a section of pipework that's our responsibility, please report it to us and we'll send someone to look at it as soon as we can. If we investigate a blockage and it's in a section of pipework that's your responsibility, our engineer will discuss this with you. Our contractor, Lanes Group, may offer to clear it at a cost of £117.

Bin it – don’t block it, and keep life flowing
It's easy to avoid blockages in your home. Remember the three Ps: pee, poo and (toilet) paper – nothing else should be flushed!
- Wrap sanitary items, nappies, wipes and condoms in toilet paper and put them in the bin.
- Leave leftover cooking oil, fat and food to cool and put it in the bin.
- Take chemicals, solvents, engine oil and paint to your local refuse or recycling site.
- Take medicines, tablets, syringes and needles to your pharmacist, hospital or health authority for safe disposal.
