Our London drainage services
Every job is different. Some problems need an urgent visit; others need investigation or planned maintenance. Our services in London are kept separate below so you can quickly see how we can help.
A blocked sink, blocked toilet or overflowing outside drain can make part of a property unusable. Clearance work begins with finding where the blockage sits, removing it with a suitable method and checking that the water is moving again. If several fixtures are affected or the water is rising, tell us when you call.

Sewage entering a property or an overflowing manhole needs urgent attention. A quick response matters because using more water can make the overflow worse. Stop using taps, toilets and appliances that discharge water, then call and explain what is happening. Drainage emergencies can happen day or night, so we will confirm the emergency response available when you call. Keep away from wastewater and do not touch electrical equipment that has become wet. If the pipe is damaged, any emergency repairs are discussed separately from the immediate clearance.

Water jetting can remove grease, silt and other deposits from suitable pipework. Before using high-pressure drainage equipment, the engineer considers the access, the likely cause and the condition of the line. Jetting is recommended when it fits the job, not simply because it is the most powerful option.

A CCTV drain survey shows what is happening inside a pipe without relying on guesswork. The footage can help locate cracks, displaced joints, root intrusion and sections where waste repeatedly catches. CCTV surveys are useful when a blockage keeps returning, the route is unclear or repair options need reliable evidence.

Grease, silt, scale and other material can gradually reduce the space inside a line. Cleaning removes that build-up before it becomes a larger drainage issue. We can discuss one-off work or a cost-effective maintenance plan for properties where the same deposits, smells or slow drainage keep returning.

Excavation is sometimes necessary for a collapsed pipe, a failed section or drainage that needs to be rerouted. It can also form part of a new installation. The route, fall, connections and access all need to be considered so the finished drainage system works as intended.

Older and altered properties do not always have an accurate record of their underground drainage. Mapping identifies accessible pipes, chambers and connections, creating a clearer picture of the site. It can support building work, help with drainage and plumbing solutions, show where new fixtures may plumb into the network or clarify how several properties share a system.

London Drainage Co supports customers in Central London, North London, East London, South London and West London, with further coverage in Greater London where available. Give us the property postcode and we will confirm coverage before arranging the job.
Central London
Access can involve loading restrictions, basements, shared service areas and busy streets. Mention anything that may affect how an engineer or equipment reaches the drain.
North London
Converted houses, flats and shared courtyards can place inspection chambers away from the affected room. Let us know if access runs through another part of the building.
East London
For homes, managed blocks and commercial sites, tell us who can provide access and whether there are gates, permits or working-hour restrictions.
South London
Drainage routes may cross gardens, side returns or shared land. Any plans or previous survey information can be useful, but they are not required before you call.
West London
If the property is rented or managed, provide the details of the tenant, concierge or site contact who can meet the engineer and approve the agreed work.
Do we cover your area?
If you are unsure whether we cover your area, call 020 4652 9799 with the postcode. We will check availability for the location rather than make you work from a general map.
There are many drainage companies in London. We believe reliable drainage work starts with a clear explanation of the problem and a recommendation grounded in what the engineer can see. If further investigation is needed, we will say so rather than presenting a guess as a permanent answer. Expert drainage is not about promising that a fault can never return; it is about carrying out the agreed work to a high standard and giving the customer useful peace of mind.
