What a running toilet is telling you
A toilet that refills by itself, hisses, or runs on after the flush is wasting water around the clock. It is almost always the inlet valve or the flush valve seal inside the cistern, and both are quick repairs.
A leak at the base of the pan is different. That is the pan seal or the connector, and water under the floor is the sort of problem that gets expensive if it is left.
Repair or replace?
If the suite is sound, we repair the internals and it is good for years. If it is cracked, badly stained, a water-hungry old model or you are refreshing the bathroom, a new suite is often better value than chasing repairs.
Most modern suites retrofit straight onto the existing plumbing, so there is no need to repair or alter the walls: the old toilet comes out, the new one goes in, and it looks brand new.
We tell you which you have and what each option costs before any work starts.
Signs your toilet needs a look
- Runs or hisses after flushing
- Refills on its own during the night
- Water on the floor around the base
- Weak or incomplete flush
- Cracks in the cistern or pan
- Rocking or loose on the floor
What we do
- Inlet and flush valve replacements
- Cistern and pan seal repairs
- Pan connector and floor flange repairs
- Full toilet suite replacements, supplied or your own
- Retrofit replacements on the existing plumbing, with no wall repairs or alterations
- Wall-hung, back-to-wall and water-saving upgrades
- Blocked toilets cleared at the source
Done properly
A toilet is only as good as the seal under it. We set the pan level, seal it correctly, connect the water with an isolation valve, and test it through several flushes before we leave. You get a toilet that stays put and stays dry.
Before and after
A tired suite out and a new one in, sealed, levelled and tested, on the same visit.

Common questions
My toilet is blocked, not broken. Is that you too?
Yes. Blocked toilets are cleared at the source rather than plunged and left. If the blockage keeps coming back, we find out why. See our blocked drains page for what that involves.
Can you fit a toilet I have bought myself?
Yes. Tell us the model before the visit so we can check it suits the existing waste position, and we install it.
How long does a replacement take?
A straightforward like-for-like swap is usually done in a couple of hours, with the old suite taken away.
