About Southwark

Southwark is a London borough on the south bank of the Thames. Southwark Council's documents place addresses in Bermondsey and Rotherhithe in SE16 and SE1, Peckham in SE15, Camberwell in SE5 and Walworth in SE17. Borough and Bankside are in SE1. This page therefore covers five postcode districts: SE1, SE5, SE15, SE16 and SE17. A blocked drain in any of them gets the same treatment. We look at what the drain is doing, clear the blockage and, if it returns, find out why.

Two parks give the borough some of its character. Burgess Park is Southwark's largest park at 56 hectares. It runs from Camberwell and Walworth in the west to Peckham and the Old Kent Road in the east. Peckham Rye Park opened as a municipal park in 1894. Both are good reasons to think about trees, because roots look for water. Old drains with open joints give them a way in.

If the blockage is in the road, it is neither ours to clear nor yours. Southwark Council says it is responsible for clearing roadside gullies, and you can report a blockage on a public road to the council. Our page on Southwark drain unblocking covers the pipes inside your boundary.

Property types: Southwark homes range from terraced houses and converted flats to larger blocks, and drains that serve several homes are common. Older properties tend to have older pipework, which is where cracked joints and root problems turn up.

Drainage in Southwark

Most blocked drains in Southwark have ordinary causes. Fat and grease go down the kitchen sink, and wipes go down the toilet. Roots enter through joints, while cracked joints catch debris. Slow draining, gurgling and smells are the early signs. This is general advice, not a claim about one street, and it applies in Bermondsey, Peckham and Camberwell alike.

Who is responsible comes next. Southwark Council's flooding page says the council clears roadside gullies. Gullies on private roads or estates belong to the landowner or management company, while Thames Water is responsible for sewers. Thames Water has been responsible for private sewers and lateral drains since 1 October 2011.

However, homeowners remain responsible for the pipe between their property and that sewer. A blockage inside your boundary is therefore generally yours to deal with. A blocked road gully is a council job, and a blocked public sewer is a job for Thames Water.

Many drains are shared between neighbouring homes, especially in terraces and flats. A fault can then sit on a shared section, not on your own pipe. Thames Water advises asking neighbours whether they have the same problem. If you are not sure where your part ends, a CCTV drain survey shows the layout and condition of the run. Our guide to a blocked drain or a blocked sewer and who is responsible in London has more.

Clearing a blockage usually starts with rodding or high-pressure jetting from the nearest access point. Jetting then cleans fat and debris from the pipe walls, which helps stop the blockage coming back. If it keeps returning, a camera survey finds the cause, whether roots, a displaced joint or a collapse. Our guide to the common causes of blocked drains in London goes through them. If you notice smells, our article on drain smells and London's lost rivers explains what may be behind them.

Blocked drains in Southwark: what we usually find

We clear blocked drains in Southwark, covering Bermondsey, Borough, Peckham, Camberwell and the SE1, SE5, SE15, SE16 and SE17 postcodes. Our engineers deal with blocked sinks, toilets and outside drains at terraces, flats and converted properties.

  • Fat and grease in kitchen sink pipes, which narrow the drain until it blocks
  • Wipes and other items flushed down toilets, which catch in the pipe
  • Roots entering through joints in older clay drains, especially near parks and street trees
  • Displaced or cracked joints that catch debris and cause repeat blockages
  • Shared drains where a fault on one section affects several neighbouring homes

We start at the nearest inspection chamber to find the blockage. Rodding clears most obstructions, while high-pressure jetting then cleans the pipe walls. We match the pressure to the age and condition of the pipe. If we cannot find the blockage, or it keeps returning, a CCTV survey shows the cause before we suggest a repair.

Southwark Council clears roadside gullies, while Thames Water is responsible for sewers. Check whether the blockage is inside your boundary before you arrange work. If a Southwark drain blocks repeatedly, tell us when you request a quote online.

Southwark drainage FAQs

Who is responsible for a blocked drain in Southwark: me, the council or Thames Water?

It depends where the blockage is. Southwark Council says it clears roadside gullies. Gullies on private roads or estates belong to the landowner or management company. Thames Water is responsible for sewers, and has been for private sewers and lateral drains since 1 October 2011. However, homeowners remain responsible for the pipe between their property and that section. A blockage inside your boundary is generally yours. If you are not sure, request a quote online, or arrange a CCTV survey to show where the problem sits.

How do I report a blocked road gully in Southwark?

A blocked roadside gully is a council matter. Southwark Council has a page for reporting a blockage on a public road. It also has a flooding form for surface water that lingers because of a blocked or damaged gully. Gullies on private roads or estates are the landowner's or management company's job. We clear blockages inside your own property.

What should I do about a blocked sink in Southwark?

Stop running water into it, and avoid pouring chemicals down. Chemicals can splash and rarely clear a solid blockage. Fat, grease, food waste and soap build-up are the usual causes. A plunger sometimes helps with a minor blockage. If the sink stays slow or gurgles, the blockage may be further along the pipe, so request a quote online.

What does drain cleaning in Southwark involve?

After rodding or unblocking, we use high-pressure water jetting. It washes fat, grease, scale and debris from inside the pipe. This restores the full bore of the drain, which helps stop the same blockage returning. It suits drains that block repeatedly or run slowly. If jetting does not solve a repeat problem, a CCTV survey can show cracks, displaced joints or roots.

What should I do before the engineer arrives, and how do I request a quote online?

Use the contact form and describe what is happening. Tell us which sink, toilet or drain is the problem, and whether water is slow or standing. Add your postcode. Meanwhile, stop using the affected fixtures and keep the area around the drain clear. Note whether it got worse after rain, because that helps us bring the right equipment.

How quickly can you respond to a blocked drain in London?

Request a quote online and tell us it is urgent. Arrival times depend on your location in London, the time of day and traffic. We cannot promise a set time, but we will do our best to attend soon.
