If a blockage is near a gas appliance and you also smell gas, leave and call 0800 111 999. Full guidance in Safety first ↓.

Is it your drain, or someone else’s?

Before you pay anyone, work out whose drain is blocked. A single fixture may be a trap or branch-waste problem; several fixtures, a neighbouring property or an external chamber can point farther downstream, but symptoms still need checking before ownership is assigned.

Inside your boundary, serving only your property: the private drain is normally the owner’s responsibility. Public lateral drains and public/shared sewers: Thames Water maintains the transferred public section.¹ Each separate upstream branch serving only one property remains private until it reaches the transferred lateral drain or sewer. The 2011 transfer did not make every pipe inside a boundary public.²

Flooding and gullies. A blocked or damaged highway gully is reported to Wandsworth. Suspected public-sewer flooding is reported to Thames Water. Main-river flooding is an Environment Agency matter, while Wandsworth leads local risk management for surface water, groundwater and ordinary watercourses.⁷ The appearance of water in a street does not by itself identify the responsible authority. Council tenants use Wandsworth’s repair route for landlord-controlled drainage.³

Blocked drains and Tooting’s flood risk

Tooting has a quirk worth knowing about. The River Graveney — a tributary of the Wandle that starts as the Norbury Brook and runs mostly underground, culverted, through Tooting — is an Environment Agency flood-warning area, “River Graveney at Tooting and Colliers Wood.”⁴ The Wandle catchment more widely carries EA flood alerts too.

Heavy-rain timing is evidence to investigate, not proof that the River Graveney, surface water or sewer capacity caused the problem. The first checks are whether one fixture or several are affected, whether the nearest inspection chamber is holding water, whether neighbours are affected and whether the highway or sewer is also surcharging. A blockage may clear temporarily yet recur because of roots, collapse, poor fall, grease or incomplete clearance. CCTV is a diagnostic method used when recurrence or suspected damage justifies it; it does not itself clear the obstruction.

Clearing a blockage safely

Diagnosis should move from the fitting outward: trap, branch waste, soil stack, private drain, then the public lateral drain or sewer. A simple first blockage may only need dismantling, plunging or rodding. Mechanical cleaning or jetting is selected for the pipe condition; fragile or damaged pipework may need a gentler method. After clearance, the plumber should flow-test the affected fixtures and inspection chamber. Repeated blockages may justify CCTV, root cutting or a separate quote for lining, excavation or collapse repair.

Safety first

A blocked drain is mainly a hygiene and water-damage problem, but treat these seriously.

Contaminated water. Water backing up from a drain or toilet can carry sewage. Keep children and pets away, don’t use the affected sink or toilet, wear gloves, wash hands thoroughly, and disinfect surfaces once cleared. If foul water is near electrical sockets or fittings, keep clear and don’t touch switches.

Chemical cleaners. Do not mix products or pour caustic cleaner into standing water. It can create hazardous fumes or splashback and may be unsuitable for some fittings or damaged pipework. Tell the drainage plumber what has already been used.

Gas. It’s rare, but if a blockage is near a boiler or gas pipework and you also smell gas, leave the building and call the National Gas Emergency Service on 0800 111 999 from outside — free, 24/7.⁵

Find a verified drainage plumber by district

Tooting Broadway (SW17) — shops, cafés, takeaways and flats may share downstream drainage; fats, oils and grease from food premises and residential waste can affect the same back-of-parade run, so the plumber checks which branch and chamber are involved.
Tooting Bec (SW17) — houses where roots or pipe defects can be considered after inspection, but should not be assumed from trees or building age alone.
Upper Tooting & Furzedown (SW17) — terraces and conversions where separate private branches may join a shared/public downstream section; the affected fixtures and inspection chambers establish where the restriction sits.
Amen Corner & the Graveney streets (SW17) — heavy-rain timing may justify checking road, sewer and surface-water conditions, but does not prove the source of an individual backing drain.
Conversions, HMOs and managed flats — several gurgling fixtures can indicate a communal soil stack; access and permanent work may require the landlord or managing agent.

What it costs

The figures below are an editorial estimate only — not regulated rates, not market data, and not a published cost survey. Confirm the price before work starts, and see our London plumbing costs guide.

Blocked-drain job (indicative)	Typical range
Clear a simple blocked sink/basin/toilet	£80–£180
External drain rodding / clearance	£100–£250
High-pressure water jetting	£150–£350
CCTV drain survey	£150–£400
Out-of-hours emergency clearance	£150–£300+

Tooting sits inside the London-wide ULEZ (£12.50 daily for non-compliant vehicles), which TfL expanded across all boroughs on 29 August 2023, but outside the central Congestion Charge zone.⁶

Frequently asked questions

A private drain serving only your property is normally yours until it reaches the transferred public lateral drain or sewer. Thames Water maintains the public lateral drain and public/shared sewer section; the separate upstream branch remains private.¹ A blocked highway gully is reported to Wandsworth.

Possibly, but rain timing alone does not identify the cause. Check whether one fixture, several fixtures, the nearest chamber, neighbouring properties or the street are affected. Report a blocked highway gully to Wandsworth, suspected public-sewer flooding to Thames Water and main-river flooding to the Environment Agency.

Avoid mixing products or using caustic cleaner in standing water. It can be hazardous and may be unsuitable for the fitting or pipe condition; tell the plumber what has been used.

Possible causes include grease, wipes, hair, foreign objects, poor fall, roots, collapse or a restricted shared stack. The pattern of affected fixtures and inspection findings determines the cause; there is no single Tooting-wide default.

Report it to Wandsworth Council on 020 8871 8999 or through your area housing team.³

Why verified plumbers — not a general directory

A blocked drain often means someone coming onto your property, possibly digging, to deal with contaminated water. Whether they’re insured and who they say they are shouldn’t be a gamble.

Every listing is checked before going live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, and we confirm the plumber covers Tooting’s SW17 postcodes. For water-related work you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register.

Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. No customer middleman fee: enquiries go directly to the plumber.
