Across London properties, we attend a consistent set of issues for this service. We explain the cause clearly before recommending any work.

  • Slow-draining sink, bath, or shower
  • Toilet that won't flush properly or keeps backing up
  • Gurgling sounds from other fixtures when one drains
  • External gully or manhole overflowing after rain
  • Recurring blockages in the same drain run
  • Sewage smell from an internal or external drain

What's included

Every visit follows the same structured process. As a result, you receive a consistent standard of work whether the job is a quick clearance or a multi-stage diagnostic survey.

  • On-site assessment to locate the blockage before any work starts
  • Drain rodding for accessible, straightforward blockages
  • High-pressure jetting for grease, scale, or stubborn build-up
  • Test flush and flow check on all affected fixtures before we leave
  • Fixed price agreed in writing — no call-out fee

What drain unblocking actually involves

Drain unblocking is the clearance of an active blockage — a sink that won't drain, a toilet that won't flush, or a main run backing up — rather than routine preventive maintenance. We start by identifying the fixture and drain run affected, then access the nearest inspection point to locate the blockage before choosing a clearance method. Simple, accessible blockages are cleared with drain rods; grease, scale, or root-related build-up needs high-pressure jetting to clear fully and scour the pipe walls clean.

If a drain keeps blocking at the same point despite repeated clearance, that points to a structural cause — a displaced joint, a partial collapse, or root ingress — rather than a one-off obstruction. In that case we recommend a CCTV drain survey to identify the fault before it causes a more serious failure.

Drain unblocking vs drain cleaning — which do you need?

These are two different services, even though the terms are often used interchangeably. Drain unblocking is what you need right now if a drain is actively blocked, slow, or backing up — it's reactive, fixture-specific, and priced by blockage type and access.

Drain cleaning, by contrast, is scheduled maintenance carried out on drains that are still flowing normally — routine jetting or descaling to prevent grease and scale building up into a future blockage. If your drains are running fine and you want to stop a blockage happening in the first place, that's the service to book instead.

Our process

Assess

We identify which fixture and drain run are affected and locate the blockage from the nearest accessible inspection point before choosing a clearance method.

Clear

We clear the blockage with drain rods for simple obstructions or high-pressure jetting for grease, scale, or stubborn build-up, then test flow on all affected fixtures.

Prevent

We explain what caused the blockage and, for recurring problems, recommend a CCTV drain survey to identify and fix the underlying structural cause.

Drain Unblocking London — frequently asked questions

Do you provide drain clearance London-wide?

Yes — our drain clearance London service covers all 32 London boroughs, 24 hours a day. We clear sinks, baths, showers, toilets, external gullies, and main lateral drains running to the public sewer. We respond promptly, with urgent jobs prioritised, and fixed pricing is agreed before any work begins, with no call-out fee.

What is the difference between drain unblocking and drain clearance?

In practice the two terms are used interchangeably — both refer to clearing a blockage from a drain. We use "drain unblocking" for the immediate clearance of a specific blocked fixture or pipe, and "drain clearance" for the broader service that may also include flushing the drain run, scouring scale or debris, and confirming flow with a CCTV check. Either way, our 24/7 drain clearance London team handles the job in a single visit.
