Drains in Kensington and Chelsea: what our engineers see

Kensington and Chelsea is dominated by nineteenth-century stucco terraces, garden squares and red-brick mansion blocks. Most were connected to Bazalgette's sewers well over a century ago, so many still drain through original clay pipes with mortar joints. Over time those joints crack or shift, and that is usually where blockages and slow drainage begin.

Basements are a big part of the picture. Lower-ground flats and newer basement extensions often sit below the level of the sewer, relying on pumps or on gravity runs that leave little margin. In heavy rain, a partly blocked outlet can push water back up through basement gullies and toilets, which is why we often suggest a CCTV survey before or after basement work and point owners towards non-return valves where they make sense. Where a new basement or extension is built over or near a public sewer, Thames Water may require a build-over agreement.

Tree-lined streets and garden squares bring their own problem: London planes and other mature trees send roots towards the moisture in cracked joints, gradually choking the pipe. Meanwhile the restaurants, cafes and bars along King's Road, Kensington High Street and Portobello Road produce a steady flow of fat and grease, and kitchens without well-maintained grease traps can block shared drains quickly. High-pressure jetting clears both roots and grease, and a camera inspection shows whether the pipe underneath needs repair.

My basement flat floods from the toilet in heavy rain. What can be done?

Water rising through a basement toilet or gully usually means the drain or sewer downstream cannot cope and is backing up. We clear any blockage, then run a CCTV survey to check the pipe condition and falls. If the problem is surcharging in the public sewer, a non-return valve can help protect the flat, and Thames Water should also be told.

Who is responsible for the drains in a converted mansion block?

Usually it depends on where the blockage is. A pipe serving only one flat and within the property boundary is generally that owner's responsibility, while drains shared by several flats are often the freeholder's or managing agent's to maintain. Shared sections beyond the boundary normally belong to Thames Water. Check your lease, and we can locate the blockage with a camera first.

Should I get a CCTV drain survey before buying a period house in Kensington?

It is a sensible step. Victorian and Edwardian drains are often clay and may have cracks, root intrusion or displaced joints that a standard survey will not pick up. Our camera survey records the inside of the pipes so you know their condition before you commit, and it is particularly useful if you plan a basement or rear extension.
