Why drains block in London

Common causes of blocked drains in London

Wet wipes — labelled "flushable" but cause most London sewer blockages
Fat and grease poured down kitchen sinks solidifying in pipes
Hair and soap scum accumulating in bathroom drains over time
Tree root ingress through clay drain pipes — common in older London streets
Limescale build-up narrowing pipe bore in hard water areas
Collapsed or cracked pipe sections in Victorian-era drainage
Shared drains — blockages building up between multiple properties
Foreign objects — often in rental properties and HMOs

London landlords

Recurring blocked drains in your rental property?

Frequent blockages in a rental property often indicate a structural drain issue — collapsed pipe, root ingress or inadequate pipe fall — rather than tenant misuse. A CCTV drain survey identifies the root cause and provides evidence for insurance claims or disputes with tenants.

We combine drain clearance visits with gas safety certificates, EICR electrical certificates and boiler services to reduce your landlord compliance visits.

Common questions

Blocked drains London: frequently asked

How quickly can you clear a blocked drain in London?

For severe blockages — drains overflowing into the property, toilets backing up or sewage smell — we aim to attend same day across all London boroughs. For routine blockages, we typically attend within 24 hours. Contact us with your postcode and describe the fault for an accurate response time.

What causes blocked drains in London?

Common causes of blocked drains in London include: grease and fat build-up in kitchen sinks, hair and soap scum in bathroom drains, wet wipes and hygiene products in toilets (flushable wipes are a major cause), tree root ingress in older clay drainage, scale build-up in areas with hard water, and collapsed or misaligned drain sections in Victorian-era drainage systems common across London.

Who is responsible for a blocked drain — landlord or tenant?

If the blockage is caused by misuse (e.g. wet wipes flushed by a tenant), the tenant is responsible. If it is caused by the property's drainage condition (e.g. tree root ingress, collapsed drain, scale build-up), the landlord is responsible. Shared drains between properties are typically Thames Water's responsibility.

Do you use CCTV drain surveys in London?

For recurring or unexplained blockages, we carry out CCTV drain surveys to identify the root cause — collapsed sections, root ingress, misaligned joints or serious scale build-up. This is particularly useful for older London properties with Victorian-era drainage.
