Before you do anything else

If the pan is full and rising, stop flushing. Every flush adds another six or nine litres to something that has nowhere to go, and the difference between a blockage and a flooded bathroom is usually two more flushes.

Newly fitted close-coupled toilet in a refurbished bathroom — Most blocked toilets clear without lifting anything. Some do not.

If water is backing up out of a downstairs toilet, a shower tray or a ground floor gully at the same time, that is not a toilet blockage. That is the drain run itself, and it needs a drainage engineer rather than a plunger.

What actually causes it

The only proper UK forensic study of the problem, funded jointly by Water UK, Defra and the wipes industry, examined the material pulled out of sewer blockages. Wipes made up around 93% of it. Water UK now puts the figure at 94% of blockages nationally, with roughly 2.9 billion wipes flushed a year.

So the ranking, honestly, is:

Wipes. Overwhelmingly the largest cause and it is not close.
Sanitary products and other non flushables. Cotton buds, dental floss, condoms, nappies, kitchen roll.
Too much paper, usually in a pan with a weak flush or a poor fall.
Structural problems. A fall shallower than the Building Regulations require, displaced joints, root ingress or a partial collapse. These are the ones that come back.

The “flushable” wipe question, and the answer has changed

You may have been told to look for the Fine to Flush logo. That scheme ended in March 2024 and nothing has replaced it. Water UK withdrew it because the word “flushable” was causing exactly the confusion it was meant to prevent.

So as things stand in 2026 there is no UK certification scheme for flushable wipes at all. Any wipe on a shelf making a flushability claim is doing so without an industry mark behind it. Water UK’s position is now simply the three Ps, pee, poo and paper, and bin the wipe.

A ban on plastic wet wipes takes effect in England on 19 May 2027. That does not make plastic free wipes flushable. They still break down slowly and still cause blockages. If a page tells you to buy the certified flushable ones, it has not been updated in over two years.

What you can safely try yourself

Two things, and both are worth ten minutes before you pay anyone.

A proper plunger. Not a small sink cup. A toilet plunger has a flange that seats into the outlet. Seal it, then work it steadily rather than violently. The aim is to move water back and forth through the obstruction, not to force it downstream.

Hot, not boiling, water. A bucket of hot water poured in from waist height adds volume and momentum. Boiling water can crack a ceramic pan and can soften plastic waste connections, so hot from the tap, not off the hob.

If two or three attempts do nothing, stop. Repeated plunging on a solid obstruction just pushes it further into the pipe and makes the eventual job harder.

Chemical drain cleaner, and why we would rather you did not

This is worth being straight about.

The strong acid products that genuinely shift a blockage are, at trade strength, regulated substances that a member of the public cannot legally buy. Sulphuric acid above 15% is an explosives precursor requiring a Home Office licence, and using it without one is an offence carrying up to two years’ imprisonment.

What you can buy is weaker, and it still burns. The NHS names drain cleaner explicitly among the household products that cause chemical burns, alongside oven cleaner and battery acid.

The practical problem is what happens when it does not work. You are then left with a pan or a trap full of caustic or acidic liquid, and the next person to open it up is exposed to it. That person is usually our engineer.

So if you have poured something down, tell us when you ring. Not to catch you out. So that whoever attends knows what they are opening.

There is also the pipework. Older property across our patch is more likely to have cast iron, lead, pitch fibre or early plastic waste runs, and none of those is specified for repeated strong acid exposure.

What we actually do

In order, and we stop as soon as it is cleared:

Plunging and a closet auger. A drain snake designed for a WC trap, which clears most single toilet blockages without touching the drain outside.
Rodding from the nearest inspection chamber if the blockage is past the pan.
High pressure jetting where rodding will not reach or the run is silted rather than blocked. Our jetting work follows the Water Jetting Association’s Red Code for drain and sewer cleaning.
A CCTV survey if it has blocked before, or if the clearance tells us something is wrong with the pipe rather than what went into it.

When it keeps happening, it is not what you are flushing

A drain that blocks repeatedly at the same point has a defect, and no amount of care about wipes will fix it. What we look for:

Fall

The Building Regulations set minimum gradients for foul drainage, 1:40 or 1:80 for a 100mm pipe depending on flow. A run laid too flat, or one that has settled into a back fall, will silt up regardless of what goes into it. This is common where a drain crosses made ground or runs under an extension.

Structural defects

Displaced joints, fractures, deformation, root ingress and partial collapse. A CCTV survey codes these to MSCC5, the water industry’s national defect classification standard, which matters because an MSCC5 coded report is one an insurer or a water company will actually accept. A survey that comes back as a video with a verbal opinion is not.

Access

Missing or buried rodding points, usually after a patio or a driveway went in over them.

And it might not be your drain to pay for

Worth knowing before you agree to anything.

On 1 October 2011 all private sewers and lateral drains connecting to a public sewer transferred to the sewerage undertaker. In practice, a drain shared with another property, or one that runs beyond your boundary, is very likely theirs to maintain rather than yours. A drain serving only your house and staying inside your boundary is yours.

That distinction matters a great deal in Victorian and Edwardian terraces, where a single rear run often serves an entire row. We will tell you which side of the line your blockage sits on before quoting for work on it, and if it is the water company’s we will say so.

Frequently asked questions

How do I know whether it is the toilet or the drain?

If only the toilet is affected, the blockage is almost certainly in the pan or the short run behind it. If a downstairs toilet, a shower tray and a ground floor gully are all backing up at the same time, it is the drain run itself and a plunger will not touch it.

Can I use a chemical drain cleaner?

We would not. Caustic products can damage older pipework and seals, they rarely clear a solid blockage, and they leave a pan full of corrosive liquid for whoever opens it next. If you have already poured some in, tell us before we start so we know what we are putting our hands into.

Should I keep flushing?

No. If the pan is full and rising, stop. Every flush adds another six to nine litres to something that has nowhere to go, and the difference between a blockage and a flooded bathroom is usually two more flushes.

What causes most of the toilet blockages you attend?

Wet wipes, including the ones sold as flushable, followed by sanitary products, cotton buds, and in older properties a build up on rough or damaged pipework. Occasionally it is a collapsed or root damaged run, which is a repair rather than a clearance.

Do you need to dig anything up?

Rarely. Most blockages clear with rodding or high pressure jetting through an existing access point. If we suspect damage rather than a blockage we put a camera down first, so any digging is based on a picture rather than a guess.

How quickly can you come out?

Same day for most blocked toilet calls, and we run a 24 hour emergency line if it goes wrong overnight. We will also tell you honestly on the phone whether this needs somebody tonight or whether it will safely wait until morning.
