A toilet that keeps running, won't flush, or leaks at the base is more than annoying. A running toilet wastes hundreds of litres a day and pushes up a metered water bill. The usual causes are a worn flush valve or flapper, a fill valve that won't shut off, a broken handle linkage, or a cracked cistern. We find the exact part at fault rather than replacing the whole mechanism. Since we carry the common parts on the van, most repairs finish in one visit.
We check the flush and fill valves, the flapper seal, the water level, and the base seal. This finds exactly which part has failed.
We close the toilet's own isolation valve first, since that isolates just the toilet. This lets us repair it without cutting water to the rest of the house.
We fit a like-for-like or compatible part. This replaces the flush valve, fill valve, flapper, or base seal, whichever has failed.
We flush several times and check the water level. We still confirm there's no leak at the base or cistern.
Most toilet repairs are a fixed-price job, since the faulty part is easy to spot. Request a fixed-price quote online — no call-out fee, and we confirm the price before starting.
If it's your only toilet, or it's actively leaking onto the floor, treat it as urgent. The repair itself is usually straightforward, and waiting risks water damage to the floor below. A running toilet isn't an emergency, but book it in soon. It keeps costing you money on the water bill until it's fixed.
A plumber can fix almost every running or leaking toilet. These are usually cistern and seal issues, not gas or heating work. It's only a job for someone else if the toilet sits on a shared or complex drain, since that needs separate investigation.
Some faults are simple — you can nudge a flapper back into place if it's sitting out of position. If the noise or waste keeps going, the valve or seal has worn out. At that point it needs replacing, not adjusting.
