About Battersea
Battersea (SW11 and SW8) is in the London Borough of Wandsworth. It runs from Clapham Junction and Lavender Hill down to the Thames. It takes in Battersea Park, a registered park of about 81 hectares created under an 1846 Act of Parliament. In the north-east, builders have created many new homes around Nine Elms and Battersea Power Station.
Wandsworth's Local Plan describes the Victorian and Edwardian streets around Clapham Junction as part of the area's character. Drains here therefore range from older shared runs under converted houses to the private drainage of newer apartment blocks. If a sink, toilet or outside drain is slow, our Battersea drain unblocking clears the blockage. Drain jetting in Battersea deals with grease and build-up.
For a toilet that will not flush, see blocked toilets in Battersea. When a problem keeps coming back, a CCTV drain survey in Battersea shows the cause. We also cover the wider Wandsworth borough.
Drainage in Battersea
Battersea has two quite different drainage settings. Around Clapham Junction, Lavender Hill and Battersea Park, much of the housing is older terraced and converted property. Wandsworth's Local Plan says most homes in the borough are houses in terraces, flats, maisonettes or apartments. Nine Elms and the Power Station have been heavily redeveloped, and little historic building remains there.
Most of Wandsworth has a combined sewer network that carries rainwater and foul water together. The council's flood strategy says this older system was not built for very heavy rain. It adds that sewer flooding can happen quickly and may carry contamination. Blockages are one cause.
Grease, wipes and hair are the usual culprits in a blocked sink or toilet. A drain that backs up after heavy rain is therefore worth taking seriously. The council says Thames Water is responsible for sewer flood risk, so report blocked sewers to them.
Who looks after a drain depends on what it serves. Thames Water says it has been responsible for private sewers and lateral drains since 1 October 2011. You are still responsible for the pipes between your property and that sewer, and for plumbing inside. In a converted house, one run often serves several flats, so one blockage can affect them all.
Our guide to shared drain blockages in Battersea conversions explains why. A CCTV survey shows where the fault sits. In a newer block, ask your managing agent who is responsible before you pay for work.
Building work near drains needs care too. Thames Water says you generally need a build over agreement for work within 3 metres of a public sewer. The same applies within 1 metre of where a pipe serving only your property crosses your boundary. If you plan an extension, see our guide to build over agreements for London terrace extensions. If a pipe has damage, pipe relining is a no-dig repair that avoids digging up a garden.
Blocked drains in Battersea: what we usually find
A blocked drain in Battersea (SW11 or SW8) can be a one-off clog or a sign of a deeper fault. Slow sinks, gurgling toilets, wet patches outside and overflowing drains all deserve a proper look. Battersea has older converted houses with shared drain runs, as well as newer apartment blocks. The first job is therefore to find out where the problem sits.
- Shared drain runs under converted houses, where one blockage can back up several flats
- Fat, grease and wipes building up in kitchen and bathroom pipes
- Cracked, displaced or collapsed pipes, which let soil and debris in
- Leaves and silt blocking gullies, especially after heavy rain
- Newer apartment blocks, where the managing agent may need to be involved before work starts
We start by finding where the problem is. Then we clear it with rods or high-pressure jetting. If the blockage keeps returning, a CCTV survey shows the cause, so you can choose between regular clearance and a repair. If a pipe has damage, no-dig pipe relining can repair it without digging up the garden.
In a newer apartment block, ask the managing agent who is responsible for the drainage before you arrange any work. Public sewers and lateral drains are Thames Water's responsibility. You are responsible for the pipes between your property and them.

Battersea drainage FAQs
Who is responsible for a shared drain in a Battersea flat conversion?
Thames Water says it has been responsible for private sewers and lateral drains since 1 October 2011. A shared run outside your boundary is therefore usually its job. You remain responsible for the pipes between your property and that sewer, and for plumbing inside. If several flats lose their drains at once, the blockage is usually on a shared run. A CCTV survey can show which section has the fault.
Why do drains in converted Battersea houses block more often?
Many period houses were split into several flats. The drain under the building may be one run that now carries waste from several kitchens and bathrooms. When it blocks, every flat on that run feels it at once. Grease, wipes and hair are common causes. Clearing the run helps, but if it keeps blocking, a CCTV survey shows whether the pipe has a fault.
Do I need permission to build an extension near a drain in Battersea?
You may. Thames Water says you generally need a build over agreement for work within 3 metres of a public sewer. The same applies within 1 metre of where a pipe serving only your property crosses your boundary. A CCTV survey before the design is final can show where the pipes run. Check with Thames Water before work starts.
Who looks after the drains in Nine Elms and the Battersea Power Station area?
It depends on the pipe. Public sewers and lateral drains are Thames Water's responsibility. In a newer apartment block, the owner or managing agent often looks after the pipes inside the building and on the estate. Ask them first before you arrange any work. Wandsworth Council says you should report blocked sewers and sewer flooding to Thames Water.
Can heavy rain cause drain problems in Battersea?
It can. Wandsworth Council says most of the borough has a combined sewer network. This older system was not built for very heavy rain. Sewer flooding can happen quickly and may carry contamination. If water backs up after heavy rain, keep gullies clear and report sewer flooding to Thames Water. Tell us if a private drain has a blockage.
