24/7 & EMERGENCY?

Emergency Drainage in London

Blocked, flooded or overflowing drains, day or night

Our emergency drainage service in London runs 24 hours a day, 7 days a week, for homes and businesses. If sewage is backing up into a toilet or shower, a manhole is overflowing into the garden or a drain has flooded after heavy rain, call us and an engineer will come out to clear it. There is no call-out fee. Emergency work is part of our drainage services, and for everyday blockages you can also book our drain clearance team.

Emergency drainage services

EMERGENCY:
AVAILABLE 24/7

Drain blocked or overflowing out of hours? We offer 24 hour drain unblocking for homes, landlords and businesses across London, with no call-out fee and a clear price before we start.

SEWAGE BACKING UP
OVERFLOWING MANHOLES
FLOODED DRAINS

What happens when you call us

  • Your call: Tell us what you can see, whether it affects one fixture or the whole property, and we will tell you how to keep things safe until we arrive.

  • Clearing the drain: Our engineer finds the blockage and clears it with drain rods or high-pressure water jetting, then runs water through to check everything is flowing.

  • Next steps: If the drain keeps blocking, we can carry out a camera survey to find out why and give you a free fixed-price quote for any repair.

What to do while you wait

Stop using the taps, toilets, showers and appliances that drain into the blocked pipe, as every flush adds to the backflow. Keep children and pets away from sewage and overflowing manholes, and do not try to lift a heavy manhole cover on your own. If the water is coming from a pipe rather than a drain, turn off the stopcock and call our emergency plumbers instead.

Areas we cover

From busy city hubs to peaceful suburban neighborhoods, we’ve got London covered. Our expert property maintenance services ensure your home or business stays in top condition, no matter where you are in Greater London.

Amazing communication and good availability. plumber was extremely professional and arrived on time. Wish there was a bit more transparency on additional payments ie. parking and sealant.

What a fantastic company! From my first conversation with Sian to installation of my new Vaillant boiler they have been absolutely brilliant. Sian responded instantly via What's App when ever I had a question regarding pricing and installation. Sam the installer and his colleague with very friendly, professional, tidy and talked me through the full installation once completed. I have already given contact details to some of my work colleague's this morning. I will use them to service my boiler going forward in the future and for any other plumbing needs. Absolutely 1st Class Company!

Easily one of the best experiences I’ve had with tradesmen. Sian was super friendly and helpful, and then Harry showed up early, fixed the issue promptly and was a legend! Highly recommended.

I’ve been dealing with ongoing pump issues for as long as I can remember, and after multiple visits from different plumbers, nothing ever fully got resolved. Harry from Jennings was the first to actually diagnose the problem and sort it in one visit. Professional, efficient, and clearly knows his craft inside out. I couldn’t recommend Jennings more highly.
