Blocked Drains (Emergency)

A blocked drain rarely stays a small problem for long. What starts as a slow gully or a bad smell can quickly become a full back-up, flooding, or even an overflowing manhole, especially during heavy rainfall.

ICE Drainage provides rapid emergency blocked drain call-outs for homes and businesses across London and the Home Counties, with strong experience supporting hospitality sites where downtime and hygiene risk are critical.

Acting quickly can make all the difference

When drains are blocked, pressure builds in the system. If it can't flow away, it will find another route, often through toilets, sinks, floor drains, or manholes.

Delaying an emergency call-out can lead to internal back-ups and contamination, flooding in kitchens, bathrooms, basements, or plant rooms, damage to floors, walls, fixtures, and electrics, persistent odours and hygiene issues, and business disruption or potential closure.

If your drains are backing up or you've got standing water, it's best to act immediately.

Signs you need emergency drain unblocking

Not every slow drain is an emergency, but these symptoms usually are: water backing up in sinks, showers, toilets, or floor drains, multiple fixtures blocked at the same time, gurgling sounds and air bubbles when flushing or draining, foul smells coming from drains or manholes, overflowing external gullies or pooling around drains, or an overflowing manhole or sewage visible on site.

If you're seeing foul water, treat it as contaminated and keep people away from the affected area. Then call ICE Drainage.

What causes emergency blocked drains?

Blocked drains happen for lots of reasons, some simple, others a sign of something deeper. Common causes we deal with include fat, oil, and grease build-up, very common in hospitality, wet wipes, sanitary products, nappies, and other non-flushable items, food waste, coffee grounds, and debris, silt build-up and sediment in lines, root ingress catching debris and restricting flow, collapsed, cracked, or displaced pipework, blocked gullies and rainwater lines during heavy rainfall, and poor drainage design or insufficient capacity.

If the same drain keeps blocking, it's a sign the root cause hasn't been fixed. We can help you identify what's really going on.

Our emergency blocked drain response

Our goal is to restore flow quickly, minimise disruption, and reduce the risk of it happening again.

Our emergency response typically includes a rapid assessment covering contamination risk, access, and whether the issue is local or affecting the main line, locating the blockage based on symptoms, site layout, and affected fixtures, emergency unblocking to restore normal flow, jetting and debris removal where appropriate to reduce the chance of immediate re-blockage, functional testing to confirm drainage is running correctly, and advice on what likely caused the blockage and how to prevent it happening again. If there are signs of a structural defect or a recurring issue, we'll recommend the best next step.

Emergency blocked drains for hospitality and commercial sites

Blocked drains in hospitality can become urgent fast, especially in kitchens, cellars, plant rooms, and customer toilets. We support restaurants and commercial kitchens, hotels and serviced apartments, pubs and bars, retail and office premises, schools, public buildings, and managed estates, and facilities managers and multi-site operators.

We understand the pressure: you need a team that turns up prepared, communicates clearly, and gets you operational again quickly.

If you manage multiple sites, ask us about planned preventative maintenance to reduce emergency incidents and keep drainage systems reliable.

Preventing emergency blocked drains

Many emergency call-outs are preventable with a sensible maintenance plan, particularly on commercial sites. We can help reduce risk with routine drain cleaning and jetting, gully and rainwater line maintenance, interceptor servicing and silt removal, grease management support for hospitality kitchens, drain inspections and condition reporting, and reactive call-outs backed by a planned schedule.

If your site has repeat blockages, we can recommend a targeted plan based on usage, risk areas, and previous incidents.
