What to do while you wait for an engineer
- Stop using toilets, sinks and showers on the affected drain.
- Keep children and pets away from any standing water.
- Do not pour chemical drain cleaners down the drain. They can make the work harder and less safe for the engineer.
Is there a call-out charge for drain unblocking in London?
No. M.R. Drains does not charge a call-out fee, day or night. You pay for the work needed to clear and restore the drain, and we explain what that involves before we start.
Fixed price drain unblocking in London
Where the blockage can be assessed up front, we aim to agree a fixed price before work starts, so there are no surprises on the day. We provide upfront, fixed-price quotes over the phone or immediately after initial on-site inspection for standard domestic blockages, ensuring total cost transparency before jetting begins.
A typical scenario: a homeowner in Wandsworth or Clapham finds their basement gully overflowing after heavy rain. An engineer attends via the South Circular, inspects the line, confirms an upfront fixed price, and clears the blockage via high-pressure water jetting.
How much does drain clearance and jetting cost in London?
Cost depends on the type of blockage, how accessible the drain is and whether a CCTV survey or repair is needed. The table shows how the main services compare.

|---|---|---|---|
| Drain unblocking | Sinks, toilets, gullies | Access and severity | From a competitive fixed fee Standard toilet, sink, or gully unblock |
| High-pressure drain jetting | Grease, silt, debris, limescale | Pipe length and condition | Fixed-price quote Based on run length; zero call-out charges |
| Tree root removal | Roots entering joints | Extent of root growth | Fixed quote Following initial camera check |
| CCTV drain survey | Recurring blockages, unknown cause | Pipe length and report type | Fixed package rate Including HD video file and written defect report |
| Drain repair or relining | Cracked or collapsed pipes | Depth, length, method | Fixed proposal Quoted after diagnostic survey |
Reliable drain unblocking service in London
Blocked drains are usually caused by debris, grease, root growth or pipe damage, and the right fix depends on finding which one. Clearing the symptom without finding the cause is why many blockages return.
Our drain unblocking in London includes an inspection to identify the exact source of the blockage and confirm the system is fully restored. Stubborn debris, foundation movement and root penetration are all common causes, and clearing them is often harder than a DIY fix.
Drain jetting service in London
High-pressure water jetting removes grease, oil build-up, silt and foreign objects from drains and sewer pipes without digging. It is the usual first choice for stubborn blockages and routine drain cleaning in London.
How do I choose a drain clearance specialist for recurring blockages?
Choose a specialist who surveys the drain with CCTV, gives you the footage and a clear explanation, guarantees the work and confirms their insurance and accreditation. A blockage that keeps returning almost always has a cause that jetting alone will not fix.
Use this checklist when comparing companies:
- Do they offer a CCTV survey, with video and a written report?
- Do they explain the cause in plain English?
- Is the work guaranteed? M.R. Drains badges: guaranteed work, insured, CHAS accredited and background checked engineers.
- Is the price clear before work starts, and is there a call-out charge?
- Do they handle repairs as well as clearance, so you do not need a second visit?
Understanding Drain & Sewer Ownership
If the blockage is on a shared or public sewer, your water company may be responsible rather than you. A survey helps show where the fault sits.
Under UK drainage legislation, private homeowners are responsible for pipes within their property boundary serving only their home. Shared sewers or pipes outside the boundary fall under Thames Water's statutory maintenance.
Drain repair service in London
If CCTV shows damage, we repair it with relining, pipe replacement or targeted clearance, depending on the fault. We use specialist CCTV technology to examine a broken drain and find the underlying cause, then restore it with a long-term fix.
Removing tree roots from drains
Roots can look harmless from outside but cause serious damage inside the pipe. To remove them, a powered mechanical auger is fed down the sewer line to cut away the intrusion safely. Roots are cleared before they can fully obstruct the pipe.
Best drain clearance for blocked outside drains and sewers in London
For blocked outside drains, we jet the line from the access point, camera the pipe to check for damage and cut back any roots we find. This clears the blockage and tells you whether it is likely to return.
Which is right for you: jetting, CCTV survey or repair?
| Problem | Likely cause | Best first step |
|---|---|---|
| Slow drain, gurgling | Build-up in the pipe | Drain jetting |
| Repeated blockages | Roots, damage or a fault in the line | CCTV survey |
| Damp patch or sunken ground | Cracked or collapsed pipe | CCTV survey, then repair |
| Foul smells or drain flies | Damaged waste pipe or trap | CCTV survey, then repair |
