A blocked drain never fixes itself. It builds. Grease, wipes, roots and forty years of “it’ll be fine” collect in the pipe until one morning the shower is ankle-deep and the kitchen smells like something died under the floor.

Here’s the part we should probably keep to ourselves: we find blockages genuinely interesting. Every blocked drain is a little mystery. Is it a fatberg? Tree roots that found a joint in a Victorian clay pipe? A toy dinosaur? (Real find. His name is Trevor now.) The point is, the job everyone else dreads is the one we turn up excited about, with the right kit to solve it first visit.

We clear the blockage at its source, not just poke it further down the pipe to become next month’s call-out. If more than one drain is backing up at once, that usually points to the main run between your house and the sewer, and we handle that too.

What it costs: most straightforward domestic blockages in the TW area run £90–£180, rising to £150–£250 for middle-of-the-night call-outs. You get a price on the phone or at the door before any work starts, and it doesn’t change when we’re covered in the evidence.

One honest note: standing water from a blocked drain is a health hazard, and foul water backing up indoors can damage floors and walls quickly. The sooner it’s cleared, the smaller the bill. Day or night, we answer.

What to do right now

  1. Stop running water into the affected drain, sink or toilet. Every litre you add has nowhere to go.
  2. If an outside gully is overflowing, keep children and pets away from the standing water.
  3. Don't pour chemical unblocker into a fully blocked drain. It sits in the pipe, and whoever clears it (us, happily) gets a face full of it.
  4. Call us. We'll give you an honest ETA and talk you through anything urgent while we're on the way.

Blocked drains · questions

Blocked Drain: the questions we get asked most

How much does it cost to unblock a drain in the TW area?

Most blocked drains in the TW area come in between £90 and £180, and out-of-hours visits run £150 to £250. You get the price agreed on the phone or at the door before anything starts, and it does not change when we are covered in the evidence. If it turns out to be Thames Water's responsibility, we will tell you and you will not be charged for us saying so.

How quickly can you get to a blocked drain in the TW area?

Typically 60–90 min across the TW area and the wider TW area, 24 hours a day. When you call, a real person picks up and gives you an honest ETA for your actual street rather than a national average. If something needs doing before we arrive, like stopping water going into the drain, we will talk you through it on the phone.

What actually happens when you arrive?

We find the blockage before we touch anything, usually by lifting the nearest inspection chamber to see which way the water is standing. That tells us whether the problem is in your pipe or the shared run. Then we clear it at the source with rods or a jetting lance, run water through to prove it is genuinely gone, and put your covers and flowerpots back where we found them.

Why does my drain keep blocking?

A drain that re-blocks within weeks is telling you something structural is wrong, not that it needs clearing more often. The usual causes are tree roots that have found a joint, a cracked or dropped section collecting debris, or years of grease narrowing the pipe. A camera survey finds the actual cause so you stop paying to treat the symptom.

Is the blocked drain my responsibility or Thames Water's?

Roughly: pipes inside your boundary serving only your home are yours, and shared drains or sewers beyond the boundary are usually Thames Water's. The quickest tell is where it is overflowing and whether your neighbours have the same problem. We will say honestly on the phone if it sounds like their job, because a free fix for you is a fair answer from us.

Should I pour drain unblocker down it first?

Please don't, not into a fully blocked drain. The chemical has nowhere to go, so it sits in the pipe as a caustic pool, and whoever opens it up next gets a face full of it. That is usually us, and we would rather it wasn't. If the drain is completely blocked, stop adding anything to it, including water, and call.

How do I stop it happening again?

Three things prevent most repeat blockages: no fat or cooking oil down the kitchen sink, no wipes down the toilet however "flushable" the packet claims, and a gully guard to keep leaves out of the outside drain. If you have done all that and it still blocks, the pipe itself is the problem and a survey is the honest next step.

Several drains are backing up at once. Is that worse?

It usually means the blockage is further down, in the main run between your house and the sewer, rather than in one fixture. That is more urgent, because there is nowhere left for the water to go and foul water indoors damages floors quickly. Stop using water in the house and call. We handle main-run blockages as standard, day or night.

Don't wait for it to get worse.
