Common Causes of a Blocked Toilet
A blocked toilet is one of the most common call-outs we get, and it’s rarely down to one single cause. We identify the actual problem before we start, not just clear the symptom.
- Wipes, nappies and sanitary products: the single biggest cause of toilet blockages, even “flushable” wipes don’t break down the way toilet paper does. Left unaddressed, these build into a dense mass that rodding alone often can’t shift, and repeated flushing only pushes the blockage further down the pipe. We clear these with rodding first and move to jetting if the blockage has compacted.
- Limescale build-up: hard water areas see the trap and outlet gradually narrow over years, slowing flow until a blockage forms. This tends to show up as a toilet that flushes more slowly than it used to, months before it blocks completely, and rodding alone often isn’t enough once scale has built up. Jetting clears the pipe wall properly rather than just pushing through a gap.
- Foreign objects: toys, cotton buds and other items that shouldn’t go down the toilet but end up there anyway, especially in family homes. These often lodge right in the trap, causing a sudden, complete blockage rather than the gradual slowdown you get with grease or scale. We check the trap first before reaching for rodding equipment, since the object sometimes needs retrieving rather than clearing.
- A blockage further down the line: sometimes the toilet is the symptom, not the cause, and the real blockage is in the drain run beyond it. This is common where a toilet keeps blocking shortly after being cleared, a sign the problem sits further along the pipe. In these cases we recommend a CCTV survey to confirm exactly where the blockage is before repeating the same fix.

Frequently Asked Questions
We always confirm the price before starting work, so there are no surprises on the invoice.
We prioritise genuine emergencies and give you a realistic arrival window when you call.
Yes, an out-of-hours surcharge applies.
Not usually. Most toilet blockages clear with rodding or jetting through the pan or the nearest access point. Removing the toilet is a last resort, only if the blockage sits in the trap itself.
Every completed job is covered by our 1-year guarantee.
Never. Every job is completed entirely by our own team.
Recurring blockages often point to a problem further down the drain run rather than the toilet itself, a CCTV survey identifies the specific cause so we can fix it for good rather than clearing the same blockage repeatedly.
