Our emergency drain clearance service in London runs through the night, at weekends and on bank holidays. Ring 0800 689 3497 and a person answers.
We aim to reach an emergency within two hours, depending on where the vans are that night. Nothing is added to the bill for the call being urgent.

When you ring
Five questions, and the engineer leaves with the right kit and the right address.
Your full postcode and how to get in. Mention a gate code, a shared entrance or a flat number.
Which toilets, sinks or drains are affected, and whether the water is inside, outside or both.
Whether you can see a manhole cover, and whether the chamber under it is full of water.
Where the van can stop. A permit or a visitor voucher helps, because parking charges go on the invoice.
A homeowner, a tenant or a business. Tenants should have the landlord's or agent's details to hand.
Have those answers to hand and the call is over quickly. The desk is open day and night.
Call 0800 689 3497Brilliant service and team, callout and sorted within two hours and great price for the work. Easily identified the issue and cleaned everything following. Highly recommend.
Brilliant service all very professional. Problems started to arise in the restaurant on a Sunday evening and phoned in. Robert arrived within 45mins. Robert was a source of great help, talk us through the problem step by step. Issue involving the drains was resolved under an hour. Highly recommend FS Drainage!!
Top service on a bank holiday. Fast, efficient, very polite and fairly priced. Would definitely recommend.
Great service - called at 7am, had someone here within 45 minutes, issue sorted quickly. Reasonable price too.
Very quick response on a Sunday to unblock the drains that were threatening to flood our basement flat. Thank you!
Our experience with FS Drainage Services was exceptional. Gabs arranged an emergency service for us at short notice and Josh did an excellent job diagnosing and solving a complicated problem with our external pipes. He was very friendly and thoughtful and helped make a stressful situation feel a bit more manageable. Would recommend.
Mitch came out for an emergency visit to my Mum’s flat on a bank holiday . Not only did he solve the problem brilliantly, but he was so kind and caring about our situation. Couldn’t recommend him more. Thank you.
Called this morning with an emergency. Were out to me within 2 hours. Easy and efficient throughout. Will definitely use again.
On the night
An emergency clearance follows the same steps as any other job, just faster.
The engineer rings when they are on their way. You can also follow their journey to you in real time.
They open the chambers and run water from the affected fittings. That shows where the water stops and how far down the problem sits.
Rods, the machine or the jetter, whichever the blockage needs. Once it runs, they flush the line through and check every fitting that was affected.
You get photos from before and after the work, sent digitally with the invoice. If the pipe is cracked or collapsed, the report says so and what the options are.






Report it to them with our photos, and you pay nothing for the repair. Keep the report for any insurance claim.
Drain ownership
The engineer can show you exactly where the blockage sits, and that usually settles it.
