Drain Clearance & Unblocking in London
Fast drain unblocking across London
Blocked drain, sink or toilet? Jennings provides drain unblocking in London for homes and businesses, from a slow kitchen sink or bath to a blocked outside drain or sewer. We clear the blockage, find out what caused it and explain how to stop it coming back. If a drain keeps blocking, a CCTV drain survey shows exactly what’s going on inside the pipe.

How we clear blocked drains
- High-pressure water jetting: Jetting blasts grease, scale and debris out of the pipe, clearing blockages that rods and plungers can’t shift.
- CCTV drain surveys: A waterproof camera shows us the inside of your drains, so we can find cracks or root ingress without digging. You get a clear report and advice on any drain repairs needed.
- Inside and out: From blocked toilets, sinks and urinals to manholes and gullies, we handle drain clearance inside and outside your property.

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!Posted on Google![]()

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.Posted on Google![]()

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.Posted on Google![]()
